Description

Integrated bioreactor for the treatment of trade effluent and sanitary sewage
Technical field
The present invention is a kind of integrated bioreactor of handling city domestic sewage and various trade effluents.
Background technology
Existing A2-O sewage treatment process is commonly anaerobic-anoxic-aerobic process, and aerobic section is independent activated sludge process or biomembrance process.Each biological respinse unit is independently built, and has the big defective of floor space.
Activated sludge process belongs to the suspended biological treatment system, and its advantage is that microorganism in the aeration tank, each environmental element are evenly distributed, and mass-transfer efficiency is higher, and reduced investment.But the subject matter of this technology is: at first, sludge volume is big, and mud is shorter age, can not satisfy the requirement of high efficiency nitrification, and then can not realize efficient denitrification; Secondly, volumetric loading is low, causes processing efficiency low big with floor space; The 3rd, bring out that easily thread fungus is expanded etc.Biomembrance process belongs to the biological attachment Sewage treatment systems, and it utilizes biologic packing material to fix microorganism.Compare with the active sludge technology, the major advantage of biomembrance process has: long sludge age is suitable for the growth of long nitrifier of generation cycle; The Gradient distribution of dissolved oxygen on microbial film is for different microbial ecological structure and metabolism provide condition; Sewage treating efficiency height, floor space are less relatively, shock resistance is strong etc., therefore, are fit to handle trade effluent.But the main drawback of biomembrance process is that the mass-transfer efficiency between microorganism and all kinds of substrate is lower, shows as:
(1) biologic packing material in the aeration tank, form easily block up, conglomeration or channel, mass transfer is inhomogeneous, directly reduces the efficient of biomembrance process;
(2) gas-liquid contact time is short in the reactor, and the utilization ratio of oxygen is low;
(3) the aging microbial film that comes off enters and should not finish mud-water separation after the subsequent disposal system and influence effluent quality.
Summary of the invention
For anaerobic-anoxic-aerobic-settling tank in the solution prior art is built respectively, the problem that floor space is big, the contriver provides a kind of integrated bioreactor.
Integrated bioreactor for the treatment of trade effluent and sanitary sewage provided by the present invention comprises anaerobic pond, anoxic pond, Aerobic Pond and settling tank; Described integrated bioreactor integral body is barrel-shaped, and its cross section is three concentric(al) circless, is divided into anoxic pond and Aerobic Pond by dividing plate in the outmost annulus that is surrounded by two circles of outermost, and the dividing plate height is lower than reactor staving height; The middle annulus that is surrounded by interior two circles is settling tank, is anaerobic pond in the inner most circle; Anaerobic pond is connected with anoxic pond by pipeline, is provided for the underwater propeller that impels sewage, filler, mud to circulate between anoxic pond and Aerobic Pond in the Aerobic Pond, and Aerobic Pond is connected with settling tank by pipeline.
Aerating apparatus is installed at the bottom of the described Aerobic Pond pond, is carried out aeration by roots blower usually.
Shore pipe is established in described settling tank bottom.
Described anaerobic pond is connected by mud return line with the settling tank bottom.
During use, pending trade effluent and/or sanitary sewage enter in the anaerobic pond by water inlet pipe, through behind the anaerobic reaction, enter anoxic pond by the pipeline gravity flow, through behind the hypoxia response, water enters Aerobic Pond by baffle plate top gravity flow between anoxic pond and the Aerobic Pond, after Aerobic Pond is finished aerobic reaction, enter settling tank by the pipeline gravity flow, in settling tank, finish post precipitation, discharged by water shoot.Active sludge in the waste water and the microbial film that comes off precipitate in settling tank, mud is behind the settling tank bottom settlings, discharged by settling tank bottom shore pipe, a mud part of getting rid of enters mud storage pond, another part mud is back to anaerobic pond, be that mud refluxes, determine when the ratio of spoil disposal and backflow mud needs according to engineering debug; When system normally moves, in each pond body waste water is arranged, waste water is circulated between Liang Chi by the underwater propeller effect in anoxic pond and the Aerobic Pond, and waste water replaces by aerobic, anaerobic environment, i.e. the usually said backflow of those of ordinary skills.Described gravity flow is those of ordinary skills' term, refers to flow to low level by liquid level official post liquid from a high position.Filler in the anaerobic pond is to be in the filler suspension flow state, its growth inside autotrophic type anaerobic ammonia oxidizing bacteria under the effect of agitator and waterpower.Filler in anoxic pond and the Aerobic Pond be flow at this two ponds internal recycle, it is inner except growth carbon source bacterium and aerobic nitrifier, the filler of the denitrification phosphorus-collecting bacterium that also grows.
For reaching better effect, preferred, in described anaerobic pond, anoxic pond, Aerobic Pond, add BM

Biologic packing material is produced by Dalian source of students water treating equipment Development Co., Ltd, and its patent No. grant number is ZL200510047122.7.
Integrated bioreactor for the treatment of trade effluent and sanitary sewage of the present invention by in anaerobism, anoxic section filler being set, is cultivated special bacterium colonies such as autotrophic type anaerobic ammonia oxidizing bacteria and denitrification phosphorus-collecting bacterium, further improves the denitrogenation dephosphorizing effect.Purpose is the condition that is fit to filler contact sewage and abundant fluidisation by creating, and makes the reaction efficiency of different dissolved oxygen process section reach best; Mud to different floras is distinguished and is controlled age, realizes the optimization of various floras, overcomes between the different floras, and especially the mud contradiction in age of nitrifier and polyP bacteria makes denitrogenation and dephosphorization can both reach best.
The technical solution adopted for the present invention to solve the technical problems and beneficial effect are:
1. anaerobic-anoxic-aerobic-settling tank integral body arranges construction, has solved the big problem of floor space that traditional mode exists.
2. utilize organic cooperation of anaerobism, anoxic, aerobic three kinds of different envrionment conditionss and different types of microorganisms flora, and by cultivating special bacterium colonies such as autotrophic type anaerobic ammonia oxidizing bacteria and denitrification phosphorus-collecting bacterium on the filler of anaerobism and oxygen-starved area, can have simultaneously and remove organism, take off N except the function of P.
3. by control anaerobism, anoxic, aerobic condition alternate run, suppress thread fungus and breed no sludge bulking phenomenon in a large number;
4. the aerobic process that combines with biomembrance process of activated sludge process utilizes the high characteristics of pollution load of biomembrance process to reduce the structures volume on the one hand, reduces investment; Utilize the sufficient characteristics of solid-liquid separation of activated sludge process on the other hand, improve the removal efficient of organic pollutant greatly, reduce water outlet SS, guarantee that stable effluent quality is good;
5. aerobic zone adds BM
