Abstract
The invention belongs to the technical field of sewage treatment, and discloses an MABR-MBR combined type sewage treatment device. The device comprises a pre-treatment unit, an MABR unit, an MBR unit and a backflushing unit matched with the MBR unit, wherein the four units are arranged along a sewage flowing direction. The invention further discloses a control method thereof. The effect of removing nitrogen and phosphorous is well realized through the sufficient combination of advantages of two membrane reactors. Since the bubbleless aeration is adopted in an MABR pond, the utilization rate of the oxygen is high and nearly can achieve 100%. Since the mass transfer range of the oxygen is small, denitrifying bacteria and denitrifying phosphate-accumulating organism are mainly existent in the water to finish denitrification and phosphorous releasing process of the nitrate, and the performance of removing nitrogen and phosphorous in the next stage is strengthened. After entering an aerobic MBR pond, the aerobic bacteria further remove residual nitrite and ammonia nitrogen, and the aerobic phosphorous-accumulating bacteria finish the phosphorous removal work. Through the previous treatment of the MABR, the volumetric loading of the MBR is reduced.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of MABR and MBR combined type waste disposal plant and treatment process.
Background technology
As shown in Figure 1, membrane aerated bioreactor (being usually called for short MABR) is a type of membrane bioreactor, this reactor is a kind of passing through to oxygenation in the hollow-fibre membrane cavity 100 of hydrophobic, air-permeability, oxygen and pollutent form concentration difference near microbial film, centered by film chamber, both respectively incorgruous diffusions with ecto-entad from inside to outside, make the organic pollutant in sewage obtain a kind of sewage disposal technology of degrading by the metabolic consumption dissolved oxygen of microorganism in microbial film.The process that MABR system removes pollutent can be divided into following four steps: first, pollutent in water body and the anerobe in current react, make that a part of phosphoric acid salt is adsorbed, itrogenous organic substance is degraded to ammonia nitrogen, second, pollutent after degraded is with current and microbial film making contact, under concentration difference drives, spread to biological face, oxygen externally spreads by film chamber simultaneously; 3rd, pollutent is degraded to nitrate NO by metabolism by the aerobic bacteria in microbial film or double oxygen bacterium further
3 -, nitrite NO
2 -deng; 4th, the pollutent after secondary degraded enters anaerobic zone again with current, and the nitrate after conversion, nitrite are reduced into N
2, release reaches efficiencies of nitrogen removal.This reactor anoxic and coexisting of anaerobic environment also make Denitrifying Phosphate Accumulating Organisms be able to enrichment, while denitrogenation, go back part that can be removed phosphorus.
When bubble-free aeration avoids traditional aeration, in sewage, volatile substances enters air as toluene, phenol with bubble and to environment, can not produce foam due to the existence of tensio-active agent simultaneously.By foamless oxygen-supplying, oxygen transfer efficiency is greatly improved, and almost can reach 100%, and working cost also can reduce.Meanwhile, gas-liquid two-phase is using film as boundary, and the control of aerating system can be more flexible.
At present this reactor Problems existing is exactly MABR when being used alone, although there are some researches show that reactor can carry out nitrification and denitrification simultaneously, phosphor-removing effect is not good.
Film-separation biological reactor (MBR) is a kind of new and effective sewage treatment process combined with membrane filtration technique by biologic treating technique.It replaces traditional biologic treating technique end second pond with membrane module, makes to keep high reactivity sludge concentration in bio-reactor, improves biological treatment organic loading, reduces surplus sludge volume by keeping low sludge loading.Under continuous aeration condition, the aerobic bacteria in active sludge is used for autophage to a pending organic pollutant part, and a part is degraded to small-molecule substance and removes.Through the wastewater effluent bacterium of membrane biological reactor process process, suspended substance and turbidity close to zero, can also retain the contaminants of biological origin such as fecal coliform, the water outlet after process can direct reuse after sterilization.
MBR technique completes roughly divides as follows to the removal of pollutent: first, the sewage entering MBR reactor directly contacts with active sludge, continuous print aeration is not only continuously aerobic bacteria oxygenation in granule sludge, also increase the contact-impact probability of pollutent and bacterium, aerobic bacteria carries out consuming using pollutent as the nutritive substance needed for own metabolism and degrades; The second, under the suction function of producing water pump, the water after process is discharged by micropore on membrane module, and granule sludge stays on and to react in pond, and this may cause the accumulation of nitrifier, makes reactor adapted process high ammonia-nitrogen wastewater.There are some researches show, at high ammonia-nitrogen wastewater process Fang Ming, MBR reactor can reach good treatment effect.
But the utilization ratio of oxygen is too low when being used alone MBR, most oxygen is diffused in air by bubble, and aerating system energy consumption is high.The oxygen of trace is only had to be utilized by Institute of Micro-biology, easily foam is produced when there being tensio-active agent in waste water, not easily remove, and due to the raising of sludge concentration in aeration tank, the problem of fouling membrane often can be there is again in actual moving process, the shortcomings such as need frequent rinsing membrane module, the life-span that therefore can there is again film is short, and maintenance cost is high.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of MABR and MBR combined type waste disposal plant and treatment process thereof are provided.
The technical scheme adopted for realizing object of the present invention is:
