MBR污泥可滤性调控对生物脱氮的影响

摘要

采用膜生物反应器（MBR）处理模拟生活污水，向MBR中加入的臭氧，臭氧与粉末活性炭（PAC）及不同价态的金属离子等药剂，调控污泥混合液可虑性，监测反应器出水污染物含量，分析膜生物反应器在投入不同能改善污泥可滤性的药剂后，对生物脱氮效果的影响。%This subject adopts membrane bioreactor to process simulation sewage,joining ozone, ozone and PAC and different valence states of metal ions and other agents to the MBR,improve the sludge filterability. Through the long time running process of the MBR ,monitor water pollutants of the reactor, analysis the membrane bioreactor for input different potions which can improve the sludge filterability, to NH4+-N removal efficiency andNO3--N、NO2--N accumulation quantity change in the reactor. research on biological denitrification effect. And joining the potion into the sludge to get analysis and study of the growth situation of the nitric acid bacteria and the nitric acid bacteria etc microorganisms living in the sludge.
