Description

A kind of efficient anaerobic-aerobic integratedization reactor
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of efficient anaerobic-aerobic integratedization reactor.
Background technology
At present aspect the biological treatment of organic waste water, often adopting anaerobic process or the large class of aerobic method two.Anaerobic process has that accretion rate is slow, the residence time is long, container volume is large, influence factor is many, high cost unfavorable factor, aerobic method is obvious to BOD removal effect, but colourity and COD clearance are low, and the high working cost of aerobic method and the not solution of excess sludge handling problems.In view of the feature of above two kinds of methods, the aerobic coupling technique of anaerobism one becomes the main flow technique of the various high-concentration industrial-waters of current processing and sanitary sewage.
Anaerobic Methods in Treating is developed so far the history of existing more than 100 year.At first, Anaerobic Methods in Treating is mainly used in the digestion process of mud; Since the seventies, anaerobic waste water treatment technology is because it has reduced investment, working cost is low and can produce the advantages such as energy (biogas) that can provide recycling, and obtain sending out faster the development into representative, and there is a collection of anaerobic reactor treatment technology that can be detained a large amount of microbial solids with up flow anaerobic sludge blanket reactor (UASB), but UASB technical requirements is high, and granular sludge is stricter to processing requirement; Since the eighties in 20th century, people, being fully recognized that on the basis of advantage that UASB reactor for treatment technique is unique and existing deficiency, have developed some new and effective anaerobic reactor anaerobic baffled reactors.The similar a plurality of UASB reactors connection of its structure, in reactor, microorganism, with flow process alternation step by step, has ideally been realized the multistage process thought of SMPA phase-splitting, thereby has had preferably contaminant removal capacity.
Compare with other Anaerobic biotreatment method, the most obvious advantage of ABR technique is not need special consideration Gas-solid-liquid separater, due to repeatedly upper and lower baffling effect of current in reactor, having improved sludge microbe body contacts with the mixing of processed wastewater room, in compartment, formed the microorganism chain of stable performance, population no-float, to adapt to the current water quality situation of the different compartments that flows through, organism is by the dissimilar microbiological deterioration in different compartments, promoted formation and the growth of granule sludge, reactor can long-time running and is not needed spoil disposal.By reactor, reasonably design, ABR technique also can realize integrated two-phase or multiphase treating processes in a reactor, this is also that other anaerobic technique is incomparable, yet acidifying problem has become the bottleneck that the high efficiency anaerobic reactors such as restriction ABR are promoted, and how the anti-souring ability of enhancing reactor has become the focus that high-load anaerobic reactor is researched and developed.Adopt sewage backflow can avoid reactor front end compartment to cause pH value to reduce the acidifying phenomenon causing because producing more VFA, can regulate basicity, the granulating of accelerate sludge, shortens the reactor start-up time, improves the output of methane; Also can dilute the hazardous and noxious substances in water inlet, thereby improve treatment effect, reduce acidifying risk.In addition, ABR reactor is a kind of as Anaerobic treatment technique, although although organism is had to higher processing rate, but in reactor water outlet, still contain a large amount of organism, water outlet can not reach emission standard, often after anaerobic reactor, need to add aerobic treatment, further remove the organism in anaerobic reactor water outlet.
BAF (BAF) is the aerobic sewage treatment process rising the phase at the beginning of the nineties in last century, it has the advantages that to integrate bio-oxidation and hold back suspended substance, save post precipitation pond, have that volumetric loading is high, hydraulic detention time is short, initial cost is few, effluent quality advantages of higher.
The aerobic coupling technique of anaerobism one can make the poor polymer substance of biodegradability in waste water, at anaerobism section generation acidication, becomes small molecules, thereby improves wastewater biodegradability, for aerobic treatment creates conditions.But the floor space of biological treatment structures is generally larger, and structure is not compact, and its application and development are restricted.
