Description
Technical field
The utility model is a kind of integrated bioreactor of processing 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 defect that floor space is large.
Activated sludge process belongs to suspended biological treatment system, and its advantage is that microorganism in aeration tank, each environmental element are evenly distributed, and mass-transfer efficiency is higher, and reduced investment.But the subject matter of this technique is: first, sludge volume is large, mud is shorter age, can not meet the requirement of high efficiency nitrification, and then can not realize efficient denitrification; Secondly, volumetric loading is low, causes processing efficiency low large with floor space; The 3rd, easily bring out that thread fungus is expanded etc.Biomembrance process belongs to biological attachment Sewage treatment systems, and it utilizes biologic packing material to fix microorganism.Compare with active sludge technology, the major advantage of biomembrance process has: longer sludge age, is suitable for the growth of longer nitrifier of generation cycle; The Gradient distribution of dissolved oxygen on microbial film, for different microbial ecological structure and metabolism provide condition; Sewage treating efficiency is high, floor space is relatively little, shock resistance is strong etc., therefore, is applicable to processing 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 easily in aeration tank, form block up, conglomeration or channel, mass transfer is inhomogeneous, directly reduces the efficiency of biomembrance process;
(2) in reactor, gas-liquid contact time is short, and the utilization ratio of oxygen is low;
(3) the aging microbial film coming off enters and should not complete mud-water separation after subsequent disposal system and affect effluent quality.
Summary of the invention
For solving anaerobic-anoxic-oxic-settling tank in prior art, build respectively, the problem that floor space is large, contriver provides a kind of integrated bioreactor.
Integrated bioreactor for the treatment of trade effluent and sanitary sewage provided by the utility model, 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, in the outmost annulus being surrounded, by dividing plate, is divided into anoxic pond and Aerobic Pond by two circles of outermost, and dividing plate height is lower than reactor staving height; The middle annulus being surrounded by interior two circles is settling tank, in inner most circle, is anaerobic pond; 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 Aerobic Pond, and Aerobic Pond is connected with settling tank by pipeline.
Aerating apparatus is installed at the bottom of described Aerobic Pond pond, conventionally by roots blower, is carried out aeration.
Shore pipe is established in described settling tank bottom.
Described anaerobic pond is connected by mud return line with settling tank bottom.
During use, pending trade effluent and/or sanitary sewage enter in anaerobic pond by water inlet pipe, after anaerobic reaction, by pipeline gravity flow, enter anoxic pond, after hypoxia response, water enters Aerobic Pond by baffle plate top gravity flow between anoxic pond and Aerobic Pond, at Aerobic Pond, complete after aerobic reaction, by pipeline, flow automatically and enter settling tank, in settling tank, complete after precipitation, by water shoot, discharged.Active sludge in waste water and the microbial film coming off precipitate in settling tank, mud is after settling tank bottom settlings, by settling tank bottom shore pipe, discharged, a mud part of getting rid of enters sludge storage pool, another part sludge reflux is to anaerobic pond, be sludge reflux, when the ratio of spoil disposal and backflow mud need be according to engineering debug, determine; When system is normally moved, in each pond body, have waste water, in anoxic pond and Aerobic Pond, waste water, by underwater propeller effect, circulates between Liang Chi, 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 by liquid level official post liquid and flows to low level from a high position.Filler in anaerobic pond is in 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 Aerobic Pond be at this two ponds internal recycle, flow, it is inner except growth carbon source bacterium and aerobic nitrifier, the filler of the Denitrifying Phosphate Accumulating Organisms of also growing.
For reaching better effect, preferred, in described anaerobic pond, anoxic pond, Aerobic Pond, add
biological suspended packing.
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 described in the utility model, by anaerobism, anoxic section, filler being set, cultivates the special bacterium colonies such as autotrophic type anaerobic ammonia oxidizing bacteria and Denitrifying Phosphate Accumulating Organisms, further improves Nitrogen/Phosphorus Removal.Object is the condition that is applicable 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 different floras, and especially the mud contradiction in age of nitrifier and polyP bacteria, makes denitrogenation and dephosphorization can reach best.
The utility model solves technical scheme and the beneficial effect that its technical problem adopts:
1. anaerobic-anoxic-oxic-settling tank whole installation is built, and has solved the large 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 on the filler by anaerobism and oxygen-starved area, cultivate the special bacterium colonies such as autotrophic type anaerobic ammonia oxidizing bacteria and Denitrifying Phosphate Accumulating Organisms, can there is removal organism simultaneously, take off N except the function of P.
3. by controlling anaerobism, anoxic, aerobic condition alternate run, suppress thread fungus and breed in a large number, without sludge bulking phenomenon;
