Abstract
The invention relates to a double-membrane double-circulation sewage treatment process for enhancing denitrifying phosphorus removal. An anaerobic/anoxia membrane bioreactor and an aerobic membrane bioreactor are connected in series so as to enhance denitrifying phosphorus removal through a double-membrane filtration two-way circulation mode. The double-membrane double-circulation sewage treatment process comprises the steps of: firstly, carrying out anaerobic phosphorus release on phosphorus-accumulating bacteria under anaerobic condition, and storing organic matters in inflowing water as poly-beta-hydroxybutyric acid; then circulating supernate subjected to anaerobic phosphorus release to the aerobic membrane bioreactor for carrying out aerobic nitrification and degrading organic matters through a membrane assembly, circulating nitrifying liquid in the aerobic membrane bioreactor to the anaerobic/anoxia membrane bioreactor for carrying out denitrifying phosphorus removal through the membrane assembly; then filtering effluent water by utilizing the membrane assembly, and finally discharging phosphorous-rich sludge, thus realizing the phosphorous removal.

Description
Technical field
The present invention relates to technical field of waste water processing, especially a kind of two circulating water treatment process of two films of reinforced low-carbon source urban sewage denitrification dephosphorization.
Background technology
Body eutrophication is paid close attention to widely because having serious environmental hazard.Body eutrophication can affect the normal reoxygenation level of atmosphere, reduces dissolved oxygen concentration in water body, causes hydrocoles and fish kill, and aquatic algae can produce biotoxin simultaneously, also can cause that hydrobiont and person poultry poisoning are pathogenic.And anthropogenic discharge is the important factor of the body eutrophication that causes containing the trade effluent of nutritive substance (nitrogen, phosphorus) and sanitary sewage.The denitrogenation dephosphorizing usefulness that improves sewage work is one of effective measure of prevention body eutrophication generation, and in order to control the day by day serious trend of body eutrophication, many areas or country have put into effect stricter sewerage nitrogen and phosphor emission standard in succession.Recently the < < urban wastewater treatment firm pollutant emission standard > > (GB18918-2002) implementing as China has clearly stipulated total nitrogen, total phosphorus emission standard: TP≤0.5mg/L, TN≤8mg/L (one-level A standard).
Traditional biological phosphate-eliminating technology is thought, denitrification process and dephosphorization process all need to consume carbon source, there is denitrifying bacterium and the polyP bacteria problem to carbon source competition, meanwhile in China's municipal effluent, exist organic concentration more and more lower, the carbon nitrogen of sewage, the phenomenon of carbon-phosphorus ratio continuous decrease.Traditional sewage treatment process is (as A
2/ O, improvement A
2/ O, UCT, SBR etc.) there is certain denitrogenation and dephosphorization function, but owing to there being the contradiction of carbon source competition and mud difference in age at denitrogenation and dephosphorization process, dephosphorization and denitrogenation restrict mutually, actual operating performance is unsatisfactory, and there is the drawbacks such as floor space is large, energy consumption is more, and excess sludge production is larger.
At present, denitrification nitrogen and phosphorus removal technology is the focus of dirty water living creature processing technique research.Research shows, occurring in nature exists another kind of denitrifying phosphorus removing bacteria (Denitrifying phosphate Removal Bacteria, DPB), denitrifying phosphorus removing bacteria can be usingd nitrate and nitrite as final electron acceptor(EA) under anoxia condition, realizes the excessive absorption of phosphorus in water.Denitrification dephosphorization has been broken through the mechanism of anaerobic phosphorus release, aerobic suction phosphorus in traditional biological dephosphorization process, has solved the contradiction between denitrifying bacteria and polyP bacteria, is particularly useful for high nitrogen phosphorus waste water and low carbon source urban sewage.Compare with traditional technology, Denitrifying Phosphorus Removal Technology can be saved 50% organism (COD) and consume, reduces approximately 30% aeration energy consumption and 50% sludge yield, so denitrification dephosphorization is considered to be a kind of " sustainable process for removing nitrogen and phosphor from sewage ".
Two types of the current main single sludge system of technical study about denitrification dephosphorization and two sludge systems.
(1) single sludge system denitrification dephosphorization
Sequencing batch reactor (SBR) belongs to typical single sludge system denitrifying phosphorus removal technique.This technique is taked the operation scheme of sequence batch (, by anaerobism, anoxic and aerobic replacing, makes system realize the function of denitrogenation dephosphorizing.But in the operational process of SBR technique, dephosphorization bacterial, denitrifying bacteria, nitrifier etc. coexist in same active sludge, inevitably exist mud competition in age and denitrifying bacteria and the competition of dephosphorization bacterial to organism (carbon source) between nitrifier and dephosphorization bacterial, make dephosphorization and nitrated interfering with each other, cause denitrogenation dephosphorizing efficiency to be difficult to further raising.
Sequencing batch biofilm reactor (SBBR) also belongs to a kind of deformation technique of single sludge system.This technique is to utilize microbial film strengthening nitrification effect and a kind of technique of carrying out denitrogenation dephosphorizing.On microbial film, growing nitrifier and Denitrifying Phosphate Accumulating Organisms are conducive to the growth of longer nitrobacteria in mud age simultaneously on microbial film, thereby have improved the efficiency of biological denitrificaion.Because SBBR is a kind of technique deriving, therefore also exist some shortcomings in SBR on the basis of SBR.
(2) two sludge system denitrification dephosphorizations
Two sludge systems are that short distance nitration bacterium and Denitrifying Phosphate Accumulating Organisms are independent of in above-mentioned two identical reactors and are grown, and by pipeline, two reactors are connected, to realize the backflow of supernatant liquor.This technique has solved in SBR and SBBR technique carbon source competition and mud inconsistent problem in age in dephosphorization and denitrification process.But the drawbacks such as two sludge systems exist, and reactor quantity is many, mud pipeline complexity and complex operation.
In sum, Denitrifying Phosphorus Removal Technology has obvious advantage aspect current municipal effluent denitrogenation dephosphorizing, and development potentiality is huge.And the technology type of studying about denitrification dephosphorization at present mainly contains single sludge system and two sludge systems.Single sludge system (SBR, SBBR) has certain denitrification dephosphorization usefulness, but multiple population is because of mud (SBR) difference in age and different to DO and nutritional needs in single sludge system, between different microorganisms, influence each other, cause that denitrification dephosphorization usefulness is difficult to increase substantially.Two sludge systems can have been realized the enrichment of Denitrifying Phosphate Accumulating Organisms preferably as A2N technique, anaerobic-aerobic-anoxic staged reactor etc.But two sludge systems will be through repeatedly precipitation and multistage backflow, there is technical process complexity, operation inconvenience, control many weak points such as loaded down with trivial details in two sludge systems, and its denitrification dephosphorization usefulness and stability need further to be improved.
