Research on Treatment of Domestic Wastewater by Sequencing Membrane Batch Reactor

应用序批式接触氧化工艺处理生活污水。研究了水力停留时间(HRT)、曝气量、冲击负荷对处理效果的影响。研究结果表明:在HRT为6h、气水比为20∶1的条件下,采用的污水处理工艺对COD105～565mg/l、NH3-N7.2～32.6mg/l的生活污水,COD和NH3-N的平均去除率分别为94%和97%;在一定范围内,冲击负荷对处理效果的影响不大。

To treat domestic wastewater by sequencing membrane batch reactor, investigation was made to the influence of HRT, aeration flux and impulsive loading to the effluent. The result was that when HRT was 6h, the ratio of air and wastewater was 20:1, COD105~565 mg/l,NH_3-N7.2~32.6 mg/l, the average removal of COD and NH_3-N was 94%and 97% respectively, and in certain range, loading had little affect on the effluent.
