摘要
采用厌氧颗粒污泥膨胀床(EGSB)反应器在常温下处理小区生活污水,接种颗粒污泥。试验结果表明:当进水COD 411-560 mg/L,反应器容积负荷可达到3 kg COD/(m3.d),水力停留时间4 h,上升流速8 m/h,COD去除率可达到85%以上,出水COD为67-88 mg/L。并对EGSB反应器的结构及运行控制参数进行了优化,使其适宜于在常温下处理生活污水及其他低浓度有机废水。
Domestic wastewater was treated by expanded granular sludge bed reactor(EGSB). When the COD of EGSB influent was 411 -560 rag/L, the volumetric COD loading rate reached to 3 kg COD/(m^3 · d) , HRT was 4 h, up-flow rate was 8 m/h, COD removal rate reached 85% , the effluent COD was 67 -88 mg/L. In order to treat low concentration organic wastewaters, the structure and performance parameters of the reactor were optimized.
