Abstract
The utility model relates to a multi-layer self-flow biomembrane sewage treating device which is composed of a high layer filter tank 4, a middle layer filter tank 5, a low layer filter tank 6 and a sedimentation tank 7. The tanks are arranged longitudinally. Multiporous filling material 3 is loaded in each filter tank and is used for the growth of the biomembrane; a siphon tube 2 is arranged in each filter tank, and the highest point of each siphon tube 2 is below the height 1 of the designed liquid surface of each filter tank; the water inlet of the siphon tube 2 is arranged at the position which is very near to the bottom of the filter tank, and the sewage in the filter tank is discharged to the utmost extent. The utility model has the advantages of simple device and easy process control.
Description
The utility model relates to a kind of multilayer gravity flow biofilm sewage treatment device.
Dispose of sewage with biomembrance process, especially organic sewage, usually the treatment process process that adopts is, the aerobiont apposition growth is on the surface of filler, form the microbial film that colloid links to each other, under the condition that the sufficient oxygen supply is arranged, microbial film is contacted with sewage, organic dirt and the dissolved oxygen in the water in the sewage are adsorbed by microbial film, microorganism on the microbial film is constantly decomposed, these organism are synthesized in oxidation, flow out from the biological treatment structures with the sewage of handling after old and feeble microbial film comes off naturally,, can obtain conforming to the clear water of cleanliness standard again through precipitate and separate.So the general process that biomembrance process is disposed of sewage carries out with biological respinse → aeration → precipitation circulation.Keep the excess oxygen that oxidation is synthetic and aerobiont is survived in order to provide, aeration process is absolutely necessary.For this purpose, produced many technology and equipment such as tower biological filter, blodisc, biological contact oxidation process, biological fluidized bed, and all be in order to keep above-mentioned biological treatment working cycle.All there are the process control complexity in these technologies and equipment, and is with high costs, the shortcoming of mass consumption additional energy source.
The utility model has designed a kind of multilayer gravity flow biofilm sewage treatment device at this, and purpose is to overcome the shortcoming that technology and equipment in the past exist, and has simple in structurely, with low cost, and energy consumption is humble, the characteristics of automatic control process.
Structure design of the present utility model is as follows.
The utility model is made of a plurality of biological filters with certain head difference, is filled with biologic packing material in the filter tank, is used for biomembranous growth.There is siphon piping that each filter tank is connected, the vertex of siphon piping is positioned under the design liquid level in higher level filter tank, when high-rise filter tank sewage is progressively filled with vertex above siphon piping, siphonage will take place, sewage through preliminary biological respinse in the high-rise filter tank is entered the next stage filter tank rapidly, after the whole emptyings of sewage, along with the air admission siphon piping, siphonage stops, and the higher level filter tank then enters " aeration " process.Inferior one-level filter tank has the structure same with the higher level filter tank, along with entering of sewage, repeats the treating processes in higher level filter tank, and sewage is entered the next stage filter tank once more till water quality reaches standard.At last, sewage is entered settling tank precipitate, just finished the entire treatment process.When the microbial film porosity of filler in the filter tank and generation greater than 40% the time, just can not influence the generation of syphonic effect.If the siphonal flow of control, quantity and height, i.e. may command biological treatment round-robin speed; Because sewage level lifting significantly in the filter tank, oxygenizement is abundant, and oxygen in water increases severely, and biochemical action is remarkable; Because draining is rapid, can promote the aged microbial film to peel off and taken away again by flowing water.
Specifically describe a kind of embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a kind of multilayer gravity flow biofilm sewage treatment device with three metafiltration ponds.
Device is by the high-rise filter tank 4 of vertical arrangement, filter tank, middle level 5, and low layer filter tank 6 and settling tank 7 are formed; Protruded packing 3 all is housed in each filter tank, is used for biomembranous growth; Siphon pipe 2 also is housed in each filter tank, and the vertex of each siphon pipe 2 all is lower than the design liquid level 1 in filter tank separately; The water-in of siphon pipe 2 is opened in very near position, bottom, distance filter tank, to discharge the sewage in the filter tank to greatest extent; The water outlet of siphon pipe 2 is opened above next metafiltration pond or settling tank, sewage can be entered down one deck pond.Sewage at first is injected into high-rise filter tank 4, begin biochemical reaction simultaneously, when liquid level is higher than the vertex of siphon pipe 2, siphonage produces, rapidly sewage is entered filter tank, middle level 5, when high-rise filter tank 4 was continued to accept sewage and carried out new biochemical reaction, 5 in filter tank, middle level began the process that takes place in the high-rise filter tank 4 of repetition; Sewage drains into low layer filter tank 6 under continuing, and has just finished whole process until settling tank 7.
Claims (3)
1, a kind of multilayer gravity flow biofilm sewage treatment device, biological filter and a settling tank identical by a plurality of structures and that have certain head difference are formed, it is characterized in that each biological filter all is filled with the multiporous biological filler 3 that is used for biofilm development, and each filter tank is linked up mutually by siphon pipe 2.
2, according to the described a kind of multilayer gravity flow biofilm sewage treatment device of claim 1, it is characterized in that the vertex of siphon pipe 2 is positioned under the design liquid level in filter tank of living in the biological filter, water-in is then opened near as far as possible position, bottom, distance filter tank.
3, according to the described a kind of multilayer gravity flow biofilm sewage treatment device of claim 1, it is characterized in that, the multiporous biological filler 3 of filling in the biological filter, its porosity is greater than 40%.
