摘　　要：应用新型蜂窝陶瓷生物反应器处理市政污水并对其重新启动特性进行了研究。试验结果表明,在重新启动情况下,系统COD的去除率能在1d之内恢复,COD的去除率为49.7%～65.1%;接种相同水质、不同工艺内的硝化污泥能使蜂窝陶瓷反应器在24h内快速提升氨氮处理效果,使氨氮去除率从5.0%提高到85.7%,接种污泥中硝化菌是氨氮去除率快速增加的重要原因。A novel ceramic honeycomb bioreactor was investigated for treatment of municipal wastewater and the second up-start property was studied. The results shown that the COD removal rate can renew within ld under the bioreactor is secondly up-started, the COD removal rate is 49.7%-65.1%, but the ammonia removal rate is low in continually 5 d. When the nitrification sludge was inoculated into the bioreactor in the fifth day, the ammonia removal rate was heightened from 5.0% to 85.7% in the sixth day. It indicated that the nitrify bacteria in inoculated nitrification sludge is a principal cause of the ammonia rate which can rapidly improve.
