Description

Municipal effluent mixing fecal sewage A 2/ O-microbial film synchronous denitrification dephosphorizing device and method
Technical field
The present invention relates to wastewater processing technology, particularly relate to a kind of municipal effluent mixing fecal sewage A 2/ O-microbial film synchronous denitrification dephosphorizing treatment unit and technology thereof.
Background technology
In existing sewage and the biological wastewater treatment process; Removing of nitrogen phosphorus is much more complicated than the removal of carbon element; Nitrated, the denitrification that relate to nitrogen, the processes such as phosphorus and suction phosphorus of releasing of mikrobe, the purpose of above-mentioned each process is different; Mikrobe is formed, and the requirement of matrix type and envrionment conditions is also different.How in a water treatment device, organically to combine various appropriate reaction conditionss, be a significant problem.
Since Wuhrmann in 1932 utilizes the endogenous nitrogen of having set up the rear-mounted denitrification technology removal municipal effluent of mikrobe; Improvement and development through over half a century; 1984 by Deakyne, Patel and Krichten have proposed on the present engineering of water treatment to use the most general, the most succinct A of technology 1(Anaerobic) A 2(anoxic) O (Oxygen) denitrification dephosphorization technique is called for short A 1A 2O technology or title A 2/ O technology.
A 2/ O technology is made up of anaerobic zone, oxygen-starved area, aerobic zone, settling region and two return-flow systems, and its function is an anaerobic phosphorus release, the anoxic denitrification denitrogenation; Aerobic nitrification is inhaled phosphorus; After deposition, mud-water separation, discharge dephosphorization with excess sludge, but there are two big defectives in this technology:
The first, mud contradiction in age affects the effect of denitrogenation dephosphorizing.Nitrifier all belongs to autotrophic type obligate aerobic bacteria usually, and generation time is long.In winter, nitrifier breeds and is more than 30 days required generation time, even in summer, mud age less than 5 days activated sludge process system in nitrification also very faint.Mostly polyP bacteria and denitrifier are short mud mikrobe in age, and mud age, generally in 10 days, mud is short more age, and was faster more than denitrification speed, and 4 days mud is 2.5 times of 8 days mud ages age.Other has report, and in U.S. Hyperion Sewage Plant, when water temperature during at 22～24 ℃, the mud weak point in age of dephosphorization system reaches 3.1 days, and water outlet phosphorus is merely 0.4mg/L.The generation time of this explanation polyP bacteria is very short really.Unique channel of biological phosphate-eliminating is to get rid of excess sludge in addition, also requires short mud age, just can have more phosphorus to get rid of with excess sludge.Obviously; Nitrifier and polyP bacteria exist contradiction at mud on age; Common during with a backflow sludge drainage system by two quasi-microorganisms, the mud of total system has to be controlled at a very narrow scope age, though this mediation can make system possess the denitrogenation dephosphorizing function; But can not make two quasi-microorganisms performance advantage separately, influence the effect of denitrogenation dephosphorizing.
To mud contradiction in age, people have developed A again 1/ O-A 2/ O technology and A 1/ A 2/ O-O technology.This water technology is than conventional A 2/ O technology has solved mud contradiction in age limitedly, but its water treatment process is then further complicated, exists denitrifying carbon source not enough, and nitrifying sludge can not utilize again.And do not end so far, do not see better method as yet and solve mud contradictory problems in age.
The second, the nitrate salt in the returned sluge influences the effect of the dephosphorization denitrogenation of technology.At conventional A 2In/O the technology; Before anaerobic zone was located at, returned sluge can be brought a part of nitrate salt into this district inevitably, can have a strong impact on the phosphorus speed of releasing of polyP bacteria; Especially VFA is less in water inlet; When the mud phosphorus content was not high again, so the existence of nitrate salt even can cause polyP bacteria directly to inhale phosphorus was at conventional A 2Under the framework of/O technology, how to avoid nitrate salt to get into anaerobic zone and disturb polyP bacteria to release phosphorus, become the research focus, how solved the nitrate salt key of problem and be before returned sluge gets into anaerobic zone, manage its nitrate salt that carries is consumed.Around this problem people JHB technology, EASC technology, UCT technology etc. have been proposed. there is the scholar to propose the imagination of inversion A AO technology in recent years.Replace the mixed-liquor return of conventional AAO technology through refluxing with 100%～200% mud, this technology is preposition with anoxic pond, and denitrification effect is improved, and also makes anaerobic pond avoid the interference of nitrate salt.
