Replace settling tank with membrane module 54 in the present embodiment, in bio-reactor, keep high reactivity sludge concentration to reduce sewage treatment facility take up an area, and by keeping low sludge loading to reduce sludge quantity.Compared with traditional biochemical water technology, MBR has following principal feature: processing efficiency is high, effluent quality good; Facility compact, floor space are little; Easy realization controls automatically, operational management is simple.Since the eighties, this technology more and more comes into one's own, one of focus becoming research.China is very rapid to the progress of MBR, is widely used in the field such as sewage disposal and Treated sewage reusing.
50% floor space, compared with traditional, can be saved in the membrane biological reaction pond 5 provided in the present embodiment, this system can maintain higher MLSS value (< 15g/L) and the residence time short, degradation efficiency is high; For different water inlets, have stable product water water quality, surplus sludge volume is few, decreases sludge treatment expense, consumes energy low, and cleaning is simple, and working cost is low.
Membrane biological reaction pond 5 comprises biochemical part and membrane sepn part, and biochemical part adopts biological bacteria organics removal matter, and membrane sepn part adopts built-in microfiltration membrane to be separated.For submerged MBR, both using ultrafiltration membranes, also microfiltration membrane can be used.Because the gel coat on film surface also serves filteration, when processing sanitary sewage, the effluent quality of microfiltration membrane and ultra-filtration membrane does not have significant difference, therefore the many employings of submerged MBR 0.1-0.4 μm of microfiltration membrane.
But find in the research that submerged MBRs is disposed of sewage: when aeration intensity is enough large (gas-water ratio is similar to 100:1), when MLSS changes to 35g/L by 10g/L, MLSS and membrane flux do not have obvious phase husband property; If but reduced heating installation intensity, MLSS might produce certain impact to membrane flux.
Sludge concentration is the important parameter of MBR system, not only affects organic removal ability, also has an impact to membrane flux.Under certain condition, sludge concentration is higher, and membrane flux is lower.Sludge concentration is to the influence degree of membrane flux and aeration intensity, and face circulation velocity, HYDRODYNAMIC CONDITION RELATING TO etc. are closely related.All there is the critical membrane flux of a mud in a large amount of deposition in film surface to sludge concentration different in submerged MBRs, when membrane flux is less than critical membrane flux, fouling membrane causes primarily of the deposition of dissolved organic matter at face; When membrane flux is greater than critical membrane flux, fouling membrane causes primarily of the deposition of suspended sludge at face; When sludge concentration is lower, aeration intensity is little to the pollution effect of film, under middle and high sludge concentration condition, increases aeration intensity and is conducive to decelerating membrane pollution;
In anaerobism MBR, sludge concentration raises slowly, and sludge loading and volumetric loading almost correlation, therefore anaerobism MBR effluent quality is subject to the impact of volumetric loading.And in aerobic MBR, sludge concentration raises rapidly with the increase of volumetric loading, organic matter removal speed is accelerated, and sludge loading remains unchanged substantially, thus suppresses the deterioration of effluent quality.
Under the prerequisite ensureing effluent quality, membrane flux should be large as far as possible, and can reduce the usable floor area of film like this, reduce capital cost and working cost, therefore controlling diaphragm pollutes, and keeping higher membrane flux, is the important content of the research of MBR.Existing mould material can be divided into organic membrane and mineral membrane two kinds.Because higher cost of investment limits the widespread use of mineral membrane in China, domestic MBR is once all over adopting organic membrane, and conventional mould material is polyethylene, polypropylene etc.Submerged MBRs membrane reactor is in fact a kind of circulation cross flow filter mode.Design adopts subtend cross-flow fluid structure, improves intermembranous liquid upflow velocity, larger aeration rate is served wash away the cross flow filter effect on film surface to seem particularly important for submerged MBR.
Energy consumption is the important evaluation index of of sewage treatment process, is directly connected to the feasibility for the treatment of process.At present, conventional separate type MBR operation energy consumption is 3-4kwh/m
3, submerged MBR operation energy consumption is 2kwh/m
3below, far above activated sludge process 0.3-0.4kwh/m
3, higher working cost runs into subject matter during MBR applies.Many results of study show: energy consumption is the major cause causing MBR working cost high.
MBR membrane bioreactor is good as a kind for the treatment of effect, and the membrane technology of stable advanced person had been commonly used in sewage disposal and Treated sewage reusing field in recent years.Be mainly used in turbidity removal bacteriological filtration in tap water and sewage disposal and the poor industrial organic waste water process of biodegradability and the pretreatment technology as RO reverse osmosis desalination at present.
