摘　　要：对上流式分段污泥床反应器在中温(35±2)℃下处理生活污水前的启动过程进行了试验研究。反应器经过40d的启动后,当进水有机负荷为2 .2kgCOD/m3·d时,其COD去除率能稳定在80%左右,出水pH值和碳酸氢盐碱度/VFA分别大于6 .5和2,整个系统运行稳定。A laboratory study was conducted on start-up of a new anaerobic reactor——USSB before treating domestic wastewater at (35±2)℃. After the reactor had been operated for 40 days, the COD removal efficiency of USSB reactor could reach about 80% with organic loading rate 2.2 kg COD/m3·d.The pH and the ratio of bicarbonate alkalinity to VFA of effluent were above 6.5 and 2 respectively. The reactor had stable operation performance.
