Description
Technical field
The present invention is mainly concerned with the environmental protection equipment field, refers in particular to a kind of integral treatment apparatus for urban sewage.
Background technology
At present, contrast aerobe treatment technology, the advantage of anaerobic treatment is: (1) does not need oxygen supply, saves process cost; (2) the mud generation lacks 3～20 times than aerobic processes, and mud is easily handled; (3) less investment is safeguarded etc. easily.And anaerobic process produce biogas, make the energy that is stored in the organism obtain reclaiming.Along with the Chinese Urbanization's process, the quantity discharged of municipal wastewater is increasing, and anaerobic reactor also will be widely used in the municipal sewage treatment field.
Anaerobic treatment is not owing to there is the supply of oxygen, ammonia nitrogen in the sewage can not change into nitrate nitrogen and nitrous acid nitrogen by nitrification, denitrification can't be carried out, so the ammonia nitrogen in the water can't remove, cause the concentration of water outlet ammonia nitrogen of general anaerobic reaction all very high.Equally, polyP bacteria needs anaerobic and aerobic to hocket, and just can reach the removal of phosphorus, and anaerobic environment can't be removed squama separately.Therefore in various fields, use anaerobic technique and aerobic process to combine mostly and handle high-concentration waste water, at first utilize anaerobic treatment that the characteristics of very strong anti-organic loading ability are arranged, high-concentration waste water is done pre-treatment, and then the use aerobic treatment, the place to go of solving residual organic substances, ammonia nitrogen and phosphorus.But for municipal wastewater, original concentration is just very low, re-uses aerobic treatment if use anaerobic treatment earlier, will increase processing cost.Therefore for low concentration municipal wastewater, also there is no need to use aerobic and two kinds of technology bonded of anaerobism way.Yet the advantage of anaerobic technique contrast aerobic process is clearly, how directly to use anaerobic technique and handles the problem that municipal wastewater is the needs solution.
EGSB (anaerobic expanded granular sludge bed) is a kind of novel anaerobic reactor, and it can make and produce higher upflow velocity in the reactor, makes granule sludge be swelling state, keeps sewage and microorganism excellent contact state, can adapt to various COD concentration.Concerning the lower concentration municipal wastewater, the EGSB reactor can guarantee the good treatment effect.But domestic also do not have the application of EGSB on actual engineering, main is exactly because the concentration height of water outlet ammonia nitrogen and phosphorus, the anaerobion growth is slow, recirculated water can not effectively utilize water pump to pump into reactor, the swelling state of the mud of inoculating in the reactor is bad, and channeling takes place easily, and sewage can better not contact with mud, for the lower concentration municipal wastewater, fully contacting of sewage and mud is extremely important especially.Normally used in the past adsorption column filler is a gac, but a little less than the fluctuation buffering of active carbon adsorption column to ammonia nitrogen, shows as influent ammonia nitrogen and raise, and the water outlet ammonia nitrogen also raises.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem of prior art existence, the invention provides a kind of municipal effluent that can adapt to lower concentration, the COD and can effectively solve the shortcoming that anaerobic biological treatment can not denitrogenation dephosphorizing of effectively degrading, make water outlet COD, ammonia nitrogen and phosphorus all can reach the integral treatment apparatus for urban sewage of municipal sewage treatment first discharge standard.
