Specific embodiment

The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments, but these specific embodiments are not to appoint Where formula limits the protection scope of the utility model.

Embodiment 1

Referring to Fig. 1, a kind of Multifucntional filter tank, including pond body 1 and aeration tube 9, in the pond body 1 from top to bottom successively Equipped with inhalant region 2, nitrification zone 3, denitrification zone 6 and exhalant region 8, filter plate is equipped between the nitrification zone 3 and air breaking plant 5 4, it is flowed into air breaking plant 5 after being distributed uniform fluid flow, improves wastewater treatment efficiency, one end of the aeration tube 9 is stretched out Outside pond body 1, the other end is protruded into nitrification zone 3, is additionally provided between the nitrification zone 3 and denitrification zone 6 for gas collection and exhaust Air breaking plant 5.

Open Side Down and the first pipe 51 of horizontally spaced arrangement including several for the air breaking plant 5, Second pipes 52 parallel and opening upwards with the first pipe 51 are equipped with below the gap of adjacent two first pipes 51, The first pipe 51 and the both ends of second pipe 52 are connected on two opposition sides of the pond body 1, and described first The cross section of pipeline 51 and second pipe 52 is half arc.

The air breaking plant 5 further includes the gas-guide tube for gas to be discharged, one end of the gas-guide tube and described the The connection of one pipeline 51, the other end stretch out outside pond body 1.

Referring to fig. 2, when water flow flows downwardly into air breaking plant 5 from nitrification zone 3, by being equipped with several, Open Side Down First pipe 51 and opening upwards second pipe 52, water flow first it is downward from the gap between two neighboring first pipe 51 Gap between stream, then second pipe 52 along first pipe 51 and below is to flowing down, the shape inside and outside first pipe 51 At pressure difference, make to form negative pressuren zone in the opening of 51 inside of first pipe, the oxygen in water flow is inhaled into 51 inside of first pipe Opening in, then by gas-guide tube the oxygen in negative suction area is exported outside pond body 1, makes to flow into the water flow of denitrification zone 6 not It is oxygenous, it so that denitrification zone 6 be made to be in oxygen-free environment, ensure that the progress of anti-nitration reaction in denitrification zone 6, increase anti- Nitrification zone 6 removes the ability of total nitrogen, improves wastewater treatment efficiency and efficiency；The air destroys in use, and water flow exists It flows downward under gravity, the pressure difference of the generation of first pipe 51 is flowed through using water flow under field conditions (factors), in first pipe 51 insides form the area Fu Yang 15 and suck oxygen in the area Fu Yang 15, do not need additional equipment during collecting oxygen, such as Gas and liquid collecting device, pump etc. reduce the use cost of filter tank equipment when purifying sewage.

It is equipped with porous filter-material layer in the nitrification zone 3, is equipped with quartz sand filter media layer in the denitrification zone 6.

Biofilm medium of the porous filter-material layer as nitrification biology is attached to aerobic nitrification bacterium on porous filter-material layer for ammonia nitrogen It is oxidized to nitrate nitrogen；Meanwhile the particle diameter of filter medium of porous filter-material layer is small, can retain a large amount of suspended matters in sewage.Quartzy sand filtration Biofilm medium of the bed of material as denitrification biology, the anaerobic denitrifying bacterium being attached on quartz sand filter media layer handle nitrification zone 3 The nitrate nitrogen in water afterwards is reduced to nitrogen and overflows from water and complete denitrification process, while making most of suspension in waste water Object is trapped in the gap of quartz sand layer, makes clarifying contaminated liquids.

The side of 2 outer wall of inhalant region is equipped with water inlet pipe, and the inner wall of the inhalant region 2 is connected with the weir plate that catchments, described The side of 8 outer wall of exhalant region is equipped with outlet pipe 13.

Sewage first the weir plate that do not catchment to flow downwardly at the top of the weir plate that catchments again, was collected by setting after water inlet pipe inflow Weir board can first pre-process the sewage flowed into from water inlet 11, make the electrodeposition substance of bulky grain catchment weir plate with into The trench bottom that catchments that 2 inner wall of pool is formed, water flow are flowed out from the top for the weir plate that catchments, and prevent the substance of bulky grain from blocking porous filter Layer influences nitration reaction in nitrification zone 3, improves the effect of sewage treatment；Meanwhile water flow directly flows downwardly into nitrification from water inlet pipe When area 3, it will cause water-flow equation unevenly and water velocity be too fast, the utility model, which passes through, can both make water flow equipped with the weir plate that catchments It is evenly distributed when flowing into nitrification zone 3, additionally it is possible to reduce water velocity, so that sewage be made to divide in the porous filtering layer of nitrification zone 3 More evenly, sewage and the contact of porous filtering layer are more abundant for cloth, improve the treatment effeciency of sewage.

Water distribution gas distribution system 7 is additionally provided in the pond body 1, the water distribution gas distribution system 7 is located at denitrification zone 6 and exhalant region Between 8.

The filter tank further includes back-purge system, and the back-purge system includes backwash air inlet pipe 10, backwash water inlet One end of pipe 14 and backwash outlet pipe 12, the backwash air inlet pipe 10 is stretched out outside the pond body 1, and the other end protrudes into described In water distribution gas distribution system 7, the backwash water inlet pipe 14 is set on 8 outer wall of exhalant region, and the backwash outlet pipe 12 is set In on 2 outer wall of inhalant region.

After the utility model long-time use, filter tank can be backwashed by back-purge system, extend the filter tank Service life, reduce the use cost in filter tank.

The operation principle and using method of the utility model:

When a kind of Multifucntional filter tank of the utility model works, sewage enters in pond body 1 from water inlet pipe, first and does not catchment Weir plate flows downwardly into nitrification zone 3 at the top of the weir plate that catchments, and oxygen is supplied into nitrification zone 3 by aeration tube 9 simultaneously, dirty Ammonia nitrogen in water is reduced to nitrate nitrogen under the action of nitrifier in porous filter-material layer, meanwhile, the suspended matter quilt in sewage Porous filter-material layer is retained and is removed；Treated for nitrification zone 3 water is after the distribution of filter plate 4 even into flowing into air breaking plant In 5, the oxygen in water flow is inhaled into the area Fu Yang 15 formed in first pipe 51, passes through air guide after the area Fu Yang 15 is collected Pipe is discharged outside pond body 1；Water flow after being deoxygenated by air breaking plant 5 continues to flow into denitrification zone 6, the nitrate in water flow Nitrogen is reduced under the action of denitrifying bacterium of the nitrogen in quartz sand filter media layer to overflow from water and complete denitrification process；By Treated for denitrification zone 6, and water flows into water distribution gas distribution system 7, then flows out after flowing into exhalant region 8 from outlet pipe 13, completes cleaned Journey.

When being backwashed after the filter tank long-time use of the utility model, pass through backwash air inlet pipe 10 and backwash Inflation and water-filling into filter tank, water flow sequentially enter exhalant region 8, water distribution gas distribution system 7, denitrification zone 6, sky to water inlet pipe 14 respectively Gas breaking plant 5, nitrification zone 3 are finally flowed out from the backwash outlet pipe 12 of inhalant region 2, complete backwash process.
