Description
Technical field
The invention belongs to sewage treatment area, relate generally to a kind of integral type film biological reactor.
Background technology
Membrane technique is called " the third time Industrial Revolution " by home and abroad environment industry specialists as 21 century one of the most promising new and high technology.Membrane bioreactor (MBR) technology grows up over nearly 20 years, be widely used in an engineering of wastewater treatment, MBR occupies obvious technical superiority in following active sludge improving technique, can be used for the advanced treatment of municipal wastewater, sanitary wastewater, various trade effluent and micro-polluted raw, and reusing sewage field, market capacity is huge.
MBR system and technique thereof have plurality of advantages, but there is following shortcoming: 1) system oxygen requirement is large, energy consumption is high; 2) film surface easily blocking; 3) membrane module is expensive.Type selecting and the flow scheme design of the power consumption values of MBR system and membrane flux, fouling membrane situation, sludge concentration, aeration rate, system scale, pump all have relation.Therefore in lectotype selection, flow scheme design, membrane module form and mould material selection etc., doing further research and improve, is MBR future thrust.
MBR technical operation control to stablize more flexibly in addition, are the new technologies easily realizing equipmentization in sewage disposal, can realize microcomputer automatic control, thus make operational administrative more convenient.Due to the high efficiency separation effect of film, separating effect is much better than traditional settling tank, and process water outlet is extremely limpid, suspended substance and turbidity are close to zero, bacterium and virus are significantly removed, and effluent quality is better than traditional technology process, and water outlet directly can carry out reuse as non-municipal usage of drinking.Simultaneously, membrane sepn also makes microorganism and macromolecular difficult decomposed substance be dammed in bio-reactor, higher microorganism concn can be maintained in system, not only increase the overall removal efficiency of reaction unit to pollutent, also make not labile material have the longer residence time, ensure that good effluent quality.MBR membrane technique can run under high volumetric loading, low sludge loading, and excess sludge production is low, reduces sludge treatment expense.Can maintain the microbial biomass of high density in bio-reactor, treatment unit volumetric loading is high, and can save second pond, floor space is saved greatly simultaneously; This technical process is simple, compact construction, small accommodation area, do not limit by setting place, be suitable for any occasion, ground type, semi-underground type and underground type can be made.Because microorganism is dammed in bio-reactor completely, thus be conducive to breeding microorganism slowly and retain growth as nitrobacteria, system nitrification efficiency is improved.
Existing membrane bioreactor mainly adopts built-in immersion technique, carrys out the reacted active sludge mud mixture of separating bio, reaches the object of purification of water quality.Submerged hollow fiber membrane, due to cost advantage, occupies most practical application engineering case, is the main application form of membrane module.But in practical engineering application, hollow-fibre membrane also exists several obvious technological deficiency: 1) fiber yarn easily ruptures in vigorous stirring process; 2) cleaning difficulty, generally needs to take out biological reaction tank and cleans specially; 3) because high-bulk-density, making very easily by sludge blockage in reaction tank between fiber yarn, wherein the blocking of membrane module two terminal membrane silk and seal gum joint portion, is modal sludge blockage.After blocking, membrane flux sharply declines, and goes out water unstable, easily causes broken fiber filaments, and improves cleaning difficulty.
Current, fouling membrane mainly adopts the method for physical cleaning and matting to solve, and namely matting is injected in bio-reactor can the pharmaceutical chemicals of dissolved contaminants, but matting will consume pharmaceutical chemicals, can cause secondary pollution again to water.Physical cleaning method then removes pollutent from film to mechanically on the surface, to flow down greatly and flows through face, under the shear action that waterpower is formed face, rinsed by face settling mainly with water at low-voltage high speed.Physical method rinses and is used widely because of its non-secondary pollution.But existing effect of being undertaken rinsing by physical method is undesirable, still there is the problem that membrane flux reduces gradually.Therefore the membrane bioreactor designing the few easy to clean of a kind of efficient pollution seems particularly important.
