Autoprecipitation lumen 34 flows into, and can stay in large-size particle in aerobic treatment device, and longitudinal pipe 442 is connected in transverse pipe 441
Portion keeps water volume flow rate in transverse pipe 441 uniform, and then is ejected to water body uniformly tiltedly from the spout of 441 array arrangement of transverse pipe
In runner between plate 421, since the flow velocity of solid particle and liquid water body on inclined plate is different, make solid particle along inclined plate
421 slide into the blowdown chamber 43 of lower section, and 43 cross-sectional area of blowdown chamber is gradually reduced from top to bottom, make the sludgd deposition collected in blowdown
43 bottom of chamber is discharged from sewage pipe 431.And the water body for filtering out sludge flow to aeration biological filter device 5 from the 6th discharge outlet 86
It is handled.
It is equipped with volcanic rock filled layer etc. in aeration biological filter device 5, further filters the water body after precipitation process, is promoted
Then water quality is handled water body feeding dephosphorization apparatus 6, dephosphorization apparatus 6 takes conventional absorption type dephosphorization process, flocculation dephosphorization work
Skill or Biological Phosphorus Removal Processes etc. remove the P elements in water body, form the harmless water body that can be directly discharged to natural environment.Its
In, if aeration biological filter device 5 can also be saved in the discharge low-down situation of water quality requirement.
Long-chain organic matter in water body is decomposed into short by the sewage disposal system of the utility model by anaerobic processing device
Chain organic matter by anoxic treatment device and the further decomposing organic matter of aerobic treatment device and filters out nitrogen, by heavy
Shallow lake processing unit filters out the sludge in water body, water body is further filtered by aeration biological filter device, at dephosphorization
Reason device filters out P elements, so that organic matter, nitrogen, the P elements in sewage be removed, will not make after remaining discharge into water
At environmental pollution.
Those skilled in the art are considering specification and after practicing utility model disclosed herein, will readily occur to practical
Novel other embodiments.This application is intended to cover any variations, uses, or adaptations of the utility model, these
