水解酸化—膜生物反应器处理城市综合污水

Experimental Study on Treatment of Municipal Sewage with Hydrolysis Acidification-Membrane Bio-Reactor Process

分析了水解酸化—膜生物反应器(MBR)工艺处理城市综合污水的应用可行性。结果表明,利用水解酸化-MBR工艺处理污水处理厂综合污水,除TP外,出水COD、NH4+-N、TN等指标符合《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准,对出水再采用强化除磷措施(如投加化学除磷药剂等),可完全满足现阶段城市污水处理需要。

The feasibility of hydrolysis acidification-membrane bio-reactor （MBR） used in treatment of municipal sewage was analyzed. Results showed that comprehensive sewage treatment plant wastewater treated by hydrolysis acidification-membrane bio-reactor application （MBR）, the COD, NH4＋-N and TN of ultimate effluent were qualified to standard A of discharge standard of pollutants for municipal sewage treatment plant （GB18918- 2002）. Some enhanced phosphorus removal measures, such as adding chemical agent, should be applied after MBR process to reduce the effluent TP. It can fully meet the needs of urban sewage treatment.
