Abstract

PROBLEM TO BE SOLVED: To monitor waste and to prolong the life of a final disposal site where the waste is subjected to reclamation disposal as a final disposal in a reclamation area by providing a waste monitor area for monitoring whether the material inadequate for reclamation are included in the waste or not before the waste is subjected to the reclamation disposal. SOLUTION: Incombustible refuse and recyclable waste are transported to a recycle plaza 7 as an intermediate disposal facility of respective municipalities blocks A to C. The recyclable refuse is recovered as valuable matter and the rest are transported as residues to the reclamation area 2 through the waste monitor area 3 of the final disposal site 1. The waste monitor area 3 is used for monitoring whether the materials inadequate for reclamation are included in the carried waste or not before the waste is subjected to the reclamation disposal in the reclamation area 2. A watchman standing on a monitor stand monitors whether the materials inadequate for reclamation are included in the transported waste or not. If the materials inadequate for reclamation are included in a large amount in the waste, the reclamation disposal of the waste is rejected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a final disposal site for waste and a method for managing the final disposal site, and more particularly to a measure for preventing landfilling of waste containing an unsuitable landfill.

[0002]

2. Description of the Related Art Garbage from homes and businesses is collected by municipalities in collection vehicles, treated as different types of waste according to the type of waste, and unsuitable materials that are not suitable for landfill remain mixed in the waste. We are trying not to landfill.

[0003] As a general waste disposal method, for example, non-combustible waste and recyclable waste are sorted at a recycling plaza as an intermediate treatment facility, and those that can be recycled are collected as valuable resources. It is landfilled at a final disposal site as residue. Items that cannot be disposed of at the recycling plaza, such as non-combustible bulky waste, are transported directly to the final disposal site for landfill disposal.

[0004] On the other hand, combustible waste and combustible bulky waste are incinerated in an incineration plant as an intermediate treatment facility, and incineration ash, which is a residue, is detoxified by melting treatment or the like, and is disposed of at a final disposal site. Such a formulation depending on the type of waste is an important environmental issue and is mandated by the government.

[0005]

However, at present,
Since the final disposal site is not fully equipped with a function to check whether the received waste is appropriate for landfill disposal, even if the prescription according to the type of waste is obligatory as described above, the intermediate It is necessary to go through a treatment facility, but at present there is an inexperienced person who carries waste directly to a final disposal site without going through an intermediate treatment facility. In addition, it is expected that intermediate processing is not sufficiently performed even after passing through the intermediate processing facility. In these cases, the life of the final disposal site is short-lived because the unsuitable landfill is mixed into the waste. In addition, if such a terrible situation occurs, when constructing a final disposal site in the future, it will cause trouble with the residents around the planned site, and the construction of the final disposal site will not be confused.

[0006] Therefore, an intermediate treatment facility is also installed at a final disposal site, and waste that has not been subjected to intermediate treatment but should be originally treated, or waste that is insufficiently treated. Is brought to the final disposal site,
It is conceivable to perform an intermediate treatment on these wastes immediately before landfilling so that unsuitable landfills are not mixed in the wastes to be landfilled. However, setting up a number of intermediate treatment facilities with different prescriptions depending on the type of waste causes a rise in equipment costs, and is difficult to adopt due to the recent financial difficulties of local governments.

[0007] The present invention has been made in view of such a point, and an object of the present invention is to prevent the improper landfill from being mixed into the waste immediately before landfill without incurring much equipment cost, and to perform final disposal. It is to extend the life of the place.

[0008]

In order to achieve the above object, the present invention is characterized in that the waste is monitored so that the waste is not landfilled with unsuitable landfill.

Specifically, the present invention is directed to a final disposal site for waste and a method for managing the final disposal site, and has taken the following solutions.

That is, the invention according to claims 1 to 3
The present invention relates to the former landfill site where the waste collected and brought in from municipalities is landfilled as a final disposal in a landfill area. It is characterized by having a waste monitoring area for monitoring whether or not waste is unsuitable for landfill before disposal.

With the above arrangement, according to the first aspect of the present invention, the carried waste is monitored in the waste monitoring area before the landfill disposal as to whether or not an unsuitable landfill is mixed.

[0012] Therefore, if the intermediate treatment is not performed although the intermediate treatment should be performed, or if the intermediate treatment is insufficient and the unsuitable landfill is mixed in the waste, By refusing disposal or removing unsuitable landfills, waste can be prevented from being landfilled with unfilled landfills, and the life of the final disposal site can be extended.

In addition, a plurality of intermediate treatment facilities having different prescriptions depending on the types of waste are not present in the final disposal site, so that the facility cost is not so much increased and the rise of the facility cost is avoided.

According to a second aspect of the present invention, in the first aspect of the present invention, in the waste monitoring area, the waste once discharged and received in order to search for unsuitable landfills from the received waste. A receiving means is provided.

[0015] According to the above-described configuration, according to the second aspect of the invention, one mode of a monitoring system in the waste monitoring area is embodied. That is, the carried waste is once discharged and received by the waste receiving means, where the contents are exposed.

Therefore, even if a landfill unsuitable object is concealed and carried in a container or the like, this is immediately found, and illegal carrying-in action is reliably prevented.

According to a third aspect of the present invention, in the first aspect of the present invention, the waste monitoring area is provided with a landfill unsuitable material removing means for removing the unfit landfill from the waste. And

According to the above configuration, in the invention according to the third aspect, a countermeasure in a case where the landfill unsuitable is mixed into the carried waste is embodied. That is, the unsuitable landfill is removed from the waste by the unsuitable landfill removal means, and the waste suitable for the landfill that does not contain the unsuitable landfill is disposed of.

The invention according to claims 4 and 5 relates to the latter final disposal site management method in which waste collected from municipalities and carried into a final disposal site is disposed as a final disposal in a landfill area. Among them, the invention according to claim 4 is characterized in that the waste carried into the final disposal site is once discharged and received by the waste receiving means in the waste monitoring area, and the received waste is mixed with unsuitable landfill. It monitors whether or not waste is landfilled, and if it does not contain unsuitable landfills, rejects the waste, while rejects waste if it contains unsuitable landfills. I do.

According to the above configuration, an example of a method for managing a final disposal site is embodied in the invention described in claim 4. In other words, the incoming waste will be landfilled in the landfill area as planned if unsuitable landfills are not mixed,
If any unsuitable landfill is mixed in, landfill disposal will be refused and taken home.

According to a fifth aspect of the present invention, the waste carried into the final disposal site is once discharged and received by the waste receiving means in the waste monitoring area, and the received waste is mixed with an unsuitable landfill. It monitors whether or not the waste is landfilled, and if it is not landfilled, disposes of the waste.On the other hand, if the waste is landfilled, remove the waste from the waste and dispose of it. Disposal of landfills is a feature.

According to the above configuration, another management method in the final disposal site is embodied in the invention described in claim 5. In other words, the incoming waste will be landfilled in the landfill area as planned if unsuitable landfills are not mixed,
If unsuitable landfills are mixed, unsuitable landfills are removed and landfilled.

[0023]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a mode of loading waste into a final disposal site.
4 is common to all of them.

As shown in FIG. 1, the final disposal site 1 includes a landfill area 2 and a waste monitoring area 3 which is a feature of the present invention. The landfill area 2 is where landfilled waste collected and brought in from municipalities is landfilled as final disposal. The waste monitoring area 3 is used for landfilling waste carried in the landfill area 2 before landfill disposal. It is monitoring whether or not unsuitable landfills are mixed. That is, the waste is not directly carried into the landfill area 2, but is carried into the landfill area 2 through a so-called checkpoint called the waste monitoring area 3.

The wastes carried into the waste monitoring area 3 of the final disposal site 1 are treated with different prescriptions depending on the types of the wastes, except for incombustible bulky waste. In other words, garbage from homes and businesses is collected by municipalities in collection vehicles, and garbage that needs intermediate treatment is treated as waste at the intermediate treatment facility with different prescriptions depending on the type of waste, and the waste is monitored in the waste monitoring area. In step 3, it is inspected whether or not an unsuitable material that is not suitable for landfill is mixed. Also, non-combustible bulky waste that does not require intermediate treatment is once carried into the waste monitoring area 3 and inspected for unsuitable landfills.

Specifically, non-combustible garbage (ceramics, light bulbs, leather goods, etc.) and resource garbage (cans, bottles, PET bottles, waste paper, etc.) can be stored in A village block 4, B town block 5, C city block 6,.・ ・ They are brought into the recycling plaza 7 as an intermediate treatment facility for each municipal block, where they are sorted into those that can be recycled and those that cannot be recycled. Those that can be recycled are collected as valuable resources, and the rest are residues. It is carried into the landfill area 2 through the waste monitoring area 3 of the final disposal site 1 and is disposed of as landfill. In addition, items such as non-combustible bulky waste (home appliances, bicycles, etc.) that cannot be processed at the recycling plaza 7 are not directly carried into the landfill area 2 but are carried into the landfill area 2 through the waste monitoring area 3. And landfilled. In FIG.
The carry-in route indicated by an arrow from the recycling plaza 7 to the waste monitoring area 3 is a carry-in route of the residue after valuable materials have been collected from non-combustible waste and resource garbage, and a carry-in route beside it is a recycling route. This is a path for carrying incombustible bulky waste that is directly carried into the waste monitoring area 3 without passing through the plaza 7.

On the other hand, combustible waste (garbage, paper cups, cigarette butts, etc.) and oversized combustible waste (furniture, futons, etc.)
Village block 4, B town block 5, C city block 6, ...
・ They are brought into the incineration plant 8 as an intermediate treatment facility of each municipal block and incinerated, and the incineration ash, which is the residue of the incineration, is brought into the detoxification treatment plant 9 as another intermediate treatment facility and processed. The ash is detoxified (melting treatment, cement solidification treatment, chelating treatment, etc.), and is carried into the landfill area 2 via the waste monitoring area 3 of the final disposal site 1 to be landfilled.

As shown in FIGS. 2A and 2B,

The waste G, which is the residue of non-combustible refuse and resource garbage sorted at the recycling plaza 7 of each municipal block 4, 5, 6,..., The waste G, which is non-combustible oversized garbage that does not pass through the recycling plaza 7 The waste G, which is the treated ash treated in the incineration plant 8 and the detoxification plant 9, is loaded into the container t1 of the container handling vehicle T, carried into the waste monitoring area 3 of the final disposal site 1, and subjected to the disposal. It is designed to once discharge and receive into the receiving hopper 11 of the object receiving device 10 (see FIG. 2A).

The conveyor 12 conveys the waste G received in the receiving hopper 11 to the upstream side of the conveyor, and the conveyed waste G is visually monitored by an observer M climbing a monitor 13. The waste G is searched for an unsuitable landfill (not shown). Then, the conveyed waste G is not subjected to intermediate treatment without passing through the recycling plaza 7, the incineration plant 8 and the detoxification plant 9 due to the misconduct of the trader, or is passing through an intermediate treatment facility such as the recycling plaza 7. If the intermediate waste is inadequate or the landfill unsuitable is mixed in the waste G due to insufficient treatment, this is detected by the monitoring person M. Further, there is a case where the unsuitable landfill is mixed in the waste G which is the non-combustible bulky waste which is directly carried into the waste monitoring area 3 without passing through the recycling plaza 7. In this case, the unsuitable landfill is also similarly used. Can be found by the observer M.

In the middle of the conveyor 12, an unsuitable landfill removal device 14 as a means for removing unsuitable landfill is installed. This landfill unsuitable object removing device 14 is a multi-joint arm 14.
a) A claw 14b is provided at the tip, and when the observer M finds an unsuitable landfill, the unsuitable landfill removal device 14 is operated to grasp the unsuitable landfill with the claw 14b and remove it from the waste G. ing.

The container handling vehicle T is a container t1
After discharging the waste G into the receiving hopper 11, the waste G is moved below the upstream end of the conveyor 12, the inspected waste G is loaded from the conveyor 12 (see FIG. 2B), and is carried into the landfill area 2. Landfill disposal is required.

(3) The observer M climbs the monitoring platform 13 and monitors whether or not the waste G that has been conveyed is unsuitable for landfill. If the waste G does not contain any unsuitable landfill, the waste G is transported as it is and the conveyor 1
The container 2 is loaded into the container t1 of the container handling vehicle T waiting below the downstream end of the container 2, and is loaded into the landfill area 2 for landfill disposal.

On the other hand, even in the case where the landfill unsuitable material is mixed in the waste G, if the number thereof is small, the landfill unsuitable material is removed by the landfill unsuitable material removing device 14, and thereafter the same as above. It is loaded into the container t1 of the container handling vehicle T waiting below the downstream end of the conveyor 12, and is carried into the landfill area 2 for landfill disposal. However, even if the received waste G is not subjected to intermediate treatment at all without passing through the recycling plaza 7, the incineration plant 8 and the detoxification plant 9, or even if the waste G is subjected to intermediate treatment at an intermediate treatment facility such as the recycling plaza 7. If the disposal is insufficient and the amount of unsuitable landfills is large, and if the unsuitable landfills are mixed in large amounts in the waste G, which is non-combustible bulky waste that does not pass through the recycling plaza 7, the unsuitable landfills are Rejection of landfill disposal of waste G without removal, conveyor 1
The container 2 is directly loaded into the container t1 of the container handling vehicle T waiting below the downstream end of the container 2 and brought back.

As described above, the waste monitoring area 3 is provided in the final disposal site 1, and the waste receiving apparatus 10 in the waste monitoring area 3 discharges and receives the waste G, and the exposed waste G is exposed. In the process of transporting the waste by the conveyor 12, the monitor M monitors the presence or absence of the improper landfill before the landfill, so the landfill disposal of the waste G containing the inappropriate landfill is refused. In addition, by removing the unsuitable landfill with the unsuitable landfill removal device 14, it is possible to prevent the waste G from being landfilled while including the unsuitable landfill, thereby extending the life of the final disposal site 1. be able to.

Further, the container t of the container handling vehicle T
Even if the unsuitable landfill is concealed and transported in 1, the contents of the loaded waste G are exposed in the process of being conveyed by the conveyor 12 of the waste receiving device 10, so that the observer M immediately recognizes this. Thus, illegal carry-in action can be reliably prevented.

Further, a plurality of intermediate treatment facilities (recycling plaza 7, incineration plant 8,
In addition, since the detoxification treatment plant 9) does not have to be installed in the final disposal plant 1, the equipment cost can be reduced and the cost can be reduced.
