Typically use carbon steel structure, glass fibre reinforced plastic structure or PE structures.Meeting to set in the effective integrated sewage-treatment plant design of HA types
Count under parameter request, water quality reaching standard can be ensured well.
Embodiment 2：
The present embodiment is substantially the same manner as Example 1, and difference is, reference picture 2, integration excrement device 2, the sewage
Oil partiting precipitation pool 12 is additionally provided between inspection shaft 3.In the present embodiment, oil partiting precipitation pool 12 precipitates preferably by inclined plate grease
Pond 12, inclined plate grease sedimentation basin 12 be set in common oil interceptor inclination angle as 45 degree swash plate carry out oil float separation and with again
Oil, the oiliness sewage treatment structures of impurities sink down separation.It can further be filtered out after integrationization excrement device 2
Oil in sewage.
Embodiment 3：
The present embodiment is substantially the same manner as Example 1, and difference is, reference picture 3, between intermediate pool 8 and second pond 7
It is additionally provided with CASS ponds 13.Pre-reaction zone and main reaction region are divided in CASS ponds 13.In pre-reaction zone, microorganism can pass through the fast of enzyme
Most of dissolved organic matter in the fast rapid absorption effluent of transfer mechanism, the matrix Rapid Accumulation process of a high load capacity is undergone,
This plays preferable cushioning effect to influent quality, water, PH and poisonous and harmful substance, while suppression is played in the growth to der Pilz
Make and use, can effectively prevent sludge bulking；Then a substrate degradation process compared with underload is undergone in main reaction region.CASS works
Skill integrates reaction, precipitation, draining, function, and the degraded of pollutant is a plug-flow process in time, and microorganism is then located
Among aerobic, anoxic, anaerobism cyclically-varying, so as to reach to pollutant removal act on, while also have preferable denitrogenation,
Phosphorus removal functional.
Embodiment 4：
The present embodiment is substantially the same manner as Example 1, and difference is, reference picture 4, drainage pipeline 9 is connected with DC in turn
BAF 14, N BAFs 15, DN BAFs 16 and clear water reserviors 17.Clear water reserviors 17 and DC aerations are given birth to
The second reflux line 18 is connected between thing filter tank 14, N BAFs 15, DN BAFs 16；Second return duct
Backwashing pump 19 is provided with road 18.
DC+N BAFs 15 combine the nitrification of the degraded for being mainly used in dirty Organic substance in water and ammonia nitrogen.First paragraph DC
Based on organics removal, second segment N BAFs 15 mainly nitrify BAF 14 to ammonia nitrogen.In DC sections
Filter material layer, gradually reduced from water inlet end to the concentration of water side organic matter, its degradation rate also gradually successively decreases.Entrance point due to
The concentration of organic matter is higher, and heterotroph is in increased logarithmic phase, and microbial film is bred quickly.Heterotrophic microorganism turns into dominant bacteria
Kind, but autotrophic microbe is in holddown.With the progress of degradation reaction, organic concentration in filter material layer is along water (flow) direction
Gradually reduce, the heterotroph on filter material layer top is in the rise period of slowing down, and microbial film increasess slowly, and autotrophic microbe is then in
Multiplicative stage.After the processing of DC BAFs 14, the organic concentration in water outlet is in reduced levels.DC is aerated
The volumetric loading of biofilter 14 is with 3~6kgBOD5/（M3 filtrates d）It is advisable, height of filter media layer is empty between 2.5~4.5m
The hydraulic detention time of tower is not less than 45min, and 2~3mg/L should be maintained at by the remaining dissolved oxygen after filter material layer.By DC sections
After processing, the organic concentration into N sections is relatively low, and heterotrophic microorganism is less, and dominant bacteria is from nitrifier of nourishing one's nature.Due to right
Nitrifier has the material of inhibitory action, is largely removed in DC BAFs 14, and N BAFs 15 can
Effectively by the ammonium oxidation in water into nitrate or nitrite.The nitrification volumetric loading of N BAFs 15（With NH3-
N is counted）With 0.3~0.8kgNH3-N/（M3 filtrates d）It is advisable.
16 whole filter bed of DN BAFs is in anaerobic state, and under anaerobic, NO3-N and NO2-N exist
Gaseous state N2 is reduced in the presence of nitrifier, so as to realize denitrification.
Backwash uses combined water and air backwash.Backwashing water is water up to standard after processing, and back-flushing is from filter tank bottom
Flowed out into top, recoil air individually backwashes air inlet pipe from bottom, closes bottom water inlet and technique sky during backwash
Gas, water-air two-phase flow individually recoil, and are finally rinsed with water.Filtering layer has slight expansion, to the fluid scouring of filler and is filled out in air water
Between material under phase mutual friction, the biomembrane of aging and the SS being trapped are separated with filler, and filter tank is rushed out in rinse stage, recoil
Wash sludge and then return to preprocessing part.
