| 摘 要： | 我国分散型污水处理问题亟待解决,研究开发了四区一体式生物膜-活性污泥生物脱氮反应器,采用梯度缩短HRT方法,考察了冬季8~15℃水温环境下的反应器COD、NH+4-N、TN去除效果,同时,采用荧光原位杂交技术(FISH)对种泥及其启动过程中的生物膜硝化菌群(AOB、NOB)结构进行分析,并对反应器运行效果与功能微生物的相关关系进行了探讨.结果表明,在HRT为9.2 h下COD、NH+4-N、TN去除率分别为92.11%、99.21%、61.63%;启动末期生物膜内AOB、NOB数量是种泥的5.82倍、6.14倍,硝化细菌占总菌量由6.12%上升至16.38%,成为生物膜的优势菌群;末期硝化效率由初期78.49%上升至97.52%,NOB数量增长5.61倍,AOB/NOB值优化为1.47,反应器内富集生长的AOB、NOB及合适的AOB/NOB比值是确保硝化出水水质的重要保障.
