Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a gray water treatment device used to treat gray water discharged from a household, such as kitchen waste water, bath waste water or laundry waste water. Inside the treatment tank provided with an inlet, there is a first filter consisting of a separate pipe arranged in the water direction with one end inserted into the gray water inflow 1, and a space provided below the first filter. A built-in second filter and a septic layer placed on the bottom of the treatment tank below the second filter are built in, and an outlet is provided continuously on the bottom of the treatment tank to remove gray water. In addition to discharging organic waste and oil components that cause decomposition, the first
This filter and the second filter reliably capture the bacteria to prevent spoilage, and further improve air permeability to promote purification by bacteria.

Conventional technology Soil treatment equipment such as evaporation diffusion equipment is well known as a wastewater treatment method that treats domestic gray water on the premises. It is necessary to remove floating substances. Furthermore, after removing various floating substances contained in gray water, the wastewater may be discharged as is without passing through a soil treatment device. As such a gray water treatment apparatus, one having a structure as shown in FIGS. 2 and 3 is known. In Figure 2, in the front stage of soil treatment equipment l,
A sedimentation tank 2 is provided, and gray water is allowed to flow into the sedimentation tank 2 from the home, which is the gray water source, and organic waste, oil components, etc. contained in the gray water are settled in the sedimentation tank 2, and the [-clear] It is designed to directly flow through the L soil treatment device 1 or without passing through the soil treatment device.

In the conventional example shown in FIG.
At the same time, gray water poured into the settling tank 2 is sent toward the outflow 11 by overflowing the partition plate 40. The filter 3 is placed submerged in the gray water of the settling tank 2. A cage-shaped filter may be used instead of the mesh filter 3.

Problems to be Solved by the Invention - L As mentioned above, in the conventional wastewater treatment, a sedimentation tank 2 is provided, and organic waste, oil components, etc. contained in gray water are removed from the sedimentation tank 2.
The system was designed to precipitate water inside the tank and then discharge the clear water into the water, which caused the following problems.

(b) Gray water that has just been drained from a household is a mixture of ice and garbage and is not putrid. However, in the past, this miscellaneous wastewater was allowed to flow into the sedimentation tank 2 and temporarily stagnate.
Sediment 4 (Rotation occurs within the soil. Rotation not only causes a bad odor, but also causes a decrease in the processing capacity of the soil treatment equipment.

(b) Since the precipitate (a) that has turned into sludge accumulates at the bottom of the settling tank 2, it is necessary to remove it. However, not only is it difficult to remove the precipitate (a), but
Difficult problems arise, such as how to dispose of the removed precipitate (a).

(c) Since this type of fij This is a great point. However, conventional precipitation methods cannot meet this desire. As a result, filter replacement and sediment removal work were neglected, and decay and sediment (a) accumulation in sedimentation tank 2 progressed, leading to a decline in pretreatment capacity and, eventually, ■ - treatment of soil treatment equipment l. This creates a serious problem with the cap, which reduces its ability.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the gray water treatment device according to the present invention has a gray water inlet on one side and a gray water inlet inside the treatment tank. It was inserted into the gray water inlet and placed in the direction of the tree. A first filter made of a mesh pipe, a second filter disposed below the first filter at an interval, and a purification layer disposed on the bottom surface of the processing tank below the second filter. 4. An outlet is provided continuously on the bottom surface. Let it be the ν sign.

The miscellaneous wastewater discharged from households is collected in the inlet “1” installed above the treatment tank.
The water flows into the first filter from #1 and flows downward from #l[l while flowing in the direction of the water flow through the first filter. In the process, relatively coarse debris contained in the gray water is captured by the first filter. Since the first filter is made of a mesh pipe, moisture flows down and dirt is captured over the entire circumference and length of the filter, and gray water does not stagnate. Also, the first
Since the second filter is placed below the second filter with an interval, it has good ventilation and water drainage.

spoilage due to pneumobacteria in the first filter;
The occurrence of wetness etc. is suppressed. This first filter can be removed after checking the presence of garbage, and the attached garbage can be incinerated as raw garbage, used after cleaning, or replaced with a new one.

Gray water flowing down from the first filter enters a second filter spaced below it. This second filter captures oil components, minute dust, and the like. The second filter is also removably arranged so that it can be removed after checking the adsorption status of oil components and minute dust, incinerated, and washed and reused or replaced with a new one. Thereafter, the gray water is treated by the action of bacteria in the purification layer and is discharged from the outflow [1] to the subsequent soil treatment equipment. Leaked “
” is continuous with the bottom surface where the purification layer is located, so gray water is discharged smoothly without stagnation under the purification layer.

For this reason, the occurrence of rotting, sliminess, etc. due to aerobic bacteria is suppressed.

As a result, the gray water treatment device of the present invention has no place for gray water to accumulate in the route from the gray water inlet to the outlet, and moreover, it uses gray water that has just left the home and is not yet rotten. , three spills can be made into water, organic waste, and oil components. Therefore, it suppresses the progress of water rot, the accumulation of sludge, and the generation of slime, eliminates the occurrence of bad odors due to rot, and prevents pollution of the surrounding environment11;, and the removal and disposal of accumulated sludge is almost unnecessary. Thus, a gray water treatment device that is easy to handle can be obtained.

Embodiment FIG. 1 is a sectional view of a gray water treatment apparatus according to the present invention.
In the figure, 5 is a second lieutenant, and 6 is a processing tank. The second lieutenant 5 and the processing tank 6 are integrally formed using a suitable material such as metal or plastic. 2nd Lieutenant 5 opens the inflow [■51] to bubble gray water from the home into one part.

The treatment tank 6 has a gray water inlet 61 connected to the bottom surface 52 of the second lieutenant 5 at the top, and an outflow [162] at the bottom. and a purification layer 9 is built-in.

The first filter 7 is made of a mesh pipe, and one end thereof is detachably attached to the inlet [; 61 formed in the ensign 5, and is inclined or It is placed in the direction of the water without any slope. This first filter 7 has a net "1" on its entire length j-(
A structure with a structure is suitable. 71 is a gap that closes the tip of the first filter 7. The first filter 7 may have an open tip and an elbow shape bent toward the side, so that it overflows from the tip when the amount of gray water is large. A filter mat with a filter mat inserted therein can also be used.

The second filter 8 is arranged below the first filter 7 at a distance. This second filter 8 is for adsorbing minute dust, oil components, etc. that cannot be captured by the first filter 7, and is made of fibers such as coconut, in the form of a mat of an appropriate thickness, and is removable. Deploy.

The purification layer 9 is located below the second filter 8 and the treatment tank 6
It is arranged on the bottom surface 62 of. This purification layer 9 is constructed by paving purification stones to ensure air permeability. The bottom surface 63 of the treatment tank 6 in which the septic layer 9 is placed is drained [16
This is a continuation of 2.

The outflow 162 is arranged so as not to be much higher than the bottom surface 63. In addition, reference numeral 2) 1O in FIG. 1 is a hand basket for removing coarse dirt that is detachably placed inside the second lieutenant 5.

In the example described above, the gray water discharged from the home flows into the inflow tank 1.

Since the inlet 61 on the treatment tank 6 side is opened continuously, the miscellaneous wastewater that has flowed into the second lieutenant 5 does not stagnate inside the tank and is transferred from the inlet 61 to the treatment 4P! Enter 6. Since the first filter 7 arranged in the direction of the tree is inserted into the inlet 61, the gray water enters the first filter 7 from the inflow [ ] 61 and passes through the inside of the first filter 7 above the water. While flowing in the direction, it flows downward from the net [1]. In the process, relatively coarse dirt contained in the gray water is captured by the first filter 7. Since the first filter 7 is a separate pipe, the entire circumference and length of the first filter 7 is used to drain water and trap dust. Therefore, even if the treatment capacity is high and there is a large amount of gray water flowing in, no stagnation of water will occur. The first filter 7 is removably attached, so it can be removed at will depending on how much dirt is attached, and the attached dirt can be disposed of as raw garbage and reused after cleaning or replaced with a new one. Work can be done easily.

The gray water flowing down from the first filter 7 does not contain coarse waste, but contains oil components and fine waste. These oil components and minute dust are adsorbed to the second filter 8 disposed below the first filter 7 and removed. After this,
The gray water is treated by the action of bacteria in the purification layer 9 provided below the second filter 8, and is discharged from the outlet 62 of the treatment tank 6 to the soil treatment device in the rear. If there is no soil treatment equipment, the water will be discharged as is. Processing 4P
! Since the outlet 62 of No. 6 is continuous from the bottom surface 63 where the purification layer 9 is located, the 3I wastewater is smoothly discharged without being stagnated in )' of the purification layer 9.
