摘要
将活性污泥法与生物膜法相结合,开发出一种新型脱氮除磷处理工艺,成功地解决了传统工艺中硝化细菌与除磷菌之间的泥龄矛盾问题。试验结果表明,该工艺对COD、NH3-N、TP的去除率分别高达85%、95%、90%,同时处理效果稳定,对水质的适应能力也较强。
Activated sludge process was combined with biofilm process to develop a new type nitrogen and phosphorus removal process,which gave a successful solution to the contradiction of SRT between nitrifying bacteria and phosphorus-removing bacteria in traditional process.The test result shows that the process has removal rate of 85%,95%,and 90% respectively for COD,NH3-N,and TP,with stability in treatment effect and good adaptability to water quality.
