摘要
根据缺氧 好氧 (Anoxic Oxic ,A O)工艺原理设计了升流式一体化A O生物膜反应器 ,并就反应器对生活污水的处理效果和运行参数进行了试验。结果表明 ,当缺氧区HRT为 5h、好氧区HRT为 3h时对COD的去除率 >80 % (大部分接近 90 % ) ,对SS去除率 >95 % ;维持反应器内适宜的碱度可获得良好而稳定的脱氮效果 ;剩余污泥少 ,无需频繁排泥。
Upflow integrative A/O biofilm reactor was designed on the principle of anoxic/oxic process, and test was made on domestic sewage treatment effect and operational parameter. The test result showed that when HRT is 5 h and 3 h respectively in anoxic and oxic area,removal rate of COD will be more than 80% (mostly approaches to 90%) and SS more than 95%. A proper alkalinity kept in reactor may result in a good and stable nitrogen removal with less excess sludge and no frequent discharge required.
