Leading portion anoxic section and back segment aerobic section are cascaded by this equipment use A/O technique (abbreviation of Anoxic/Oxic), A section DO(dissolved oxygen) be not more than 0.2mg/L, O section DO=2 ~ 4mg/L.Anoxic section heterotrophic bacterium, the suspended contaminant such as the starch in sewage, fiber, carbohydrate and dissolved organic matter are hydrolyzed to organic acid, larger molecular organics is made to be decomposed into small organic molecule, insoluble organism changes into dissolved organic matter, when these products through anaerobic hydrolysis enter Aerobic Pond carry out aerobic treatment time, improve the biodegradability of sewage, improve the efficiency of oxygen; The pollutent such as protein, fat carried out ammonification (N in organic chain or the amino in amino acid) anoxic section heterotrophic bacterium to dissociate ammonia (NH3, NH4+), under sufficient oxygen supply condition, the nitrification of autotrophic bacteria is by NH3-N(NH4+) be oxidized to NO3-, A pond is back to by backflow control, under anoxic conditions, NO3-is reduced to molecular nitrogen (N2) and completes C, N, O circulation in ecology by the denitrification of heterotrophic bacteria, realizes sewage harmless treatment.
Anoxic pond front, the organic carbon in sewage utilize by denitrifying bacteria, can alleviate the organic loading of Aerobic Pond thereafter, the basicity that anti-nitration reaction produces can compensate in Aerobic Pond and carries out the demand of nitration reaction to basicity.Aerobic after anoxic pond, the residual organic pollutant of denitrification can be made to be removed further, improve effluent quality.The clearance comparatively Gao Keda more than 90 ~ 95% of BOD5, but Nitrogen/Phosphorus Removal is slightly poor, and nitric efficiency 70 ~ 80%, dephosphorization only has 20 ~ 30%.
Aerobic section is rear, microbial process is relied on to remove a large amount of organism and suspended substance, reduce COD and BOD5, select comprehensive aeration type contact oxidation method, the method makes certain biologic packing material be immersed in water, and the space between filling surface and filler generates membranaceous biological activated sludge, waste water is in contact with it thus is purified, for making purification ratio comparatively abundant, waste water must be made fully to circulate, repeatedly with biofilm contact.Because filler and microbial film are all immersed in water, at the bottom of pond, arrange aeration altar uniformly, air directly enters packing area and fully contacts with microbial film, and washes away it, and microbial film renewal frequency is high, and activity is strong and stable, and aeration also plays the function making waste water circulation.
In an embodiment of the present utility model, arrange built-up type many idle loops filler in biological O pond 4, this is because material specific surface area is large, microorganic adhesion space is large, and coefficient of oxygen utilization is high; Comprehensive cost is about 1/2 of honeycomb filler, 2/3 of semi soft packing.
MBR membrane cisterna replaces traditional biological treatment technology end second pond with membrane module, high reactivity sludge concentration is kept in bio-reactor, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.Active sludge in the membrane separation plant entrapping tank in aerobe pond and larger molecular organics are immersed in main utilization.
This technique not only reaches the object of mud-water separation effectively, and has the incomparable advantage of tertiary sewage treatment traditional technology:

2, the efficient crown_interception of film, makes microorganism be trapped in completely in bio-reactor, and realization response device hydraulic detention time (HRT) is separated completely with sludge age (SRT's), runs and controls to stablize flexibly.
3, because the aeration tank of traditional wastewater process and second pond unite two into one by MBR, and instead of whole process facility of tertiary treatment, therefore significantly can reduce floor space, save construction investment.
4, be beneficial to retaining and breeding of nitrobacteria, system nitrification efficiency is high.Also deamination and phosphorus removal functional can be had by the change of operation scheme.
5, because mud age can be very long, thus the degradation efficiency of hardly degraded organic substance is greatly improved.
6, reactor runs under age at high volumetric loading, low sludge loading, long mud, and excess sludge production is extremely low, because mud age can endless, can realize zero sludge discharge in theory.
After biological contact oxidation pond runs for some time, aging microbial film will come off, if get rid of not in time, the humus sludge of accumulation will affect effluent quality, so waste water must be carried out mud-water separation.
After biological contact oxidation pond, enter settling tank, conventional settling tank has rectangular sedimentation tank, vertical sedimentation basin, radical sedimentation basin, tube settler.
