| 摘 要： | 农村生活污水的随意排放对农村的生态环境构成了严重威胁,因地制宜地研发适合农村分散式生活污水处理的新技术与新工艺是解决农村水污染问题的关键所在.采用生物净化槽/强化生态浮床(BPT-EEFR)组合工艺处理崇明岛的农村生活污水,生物净化槽(BPT)可以有效地对有机物进行生物降解,强化生态浮床(EEFR)则进一步去除了氮和磷.在稳定运行的状况下,BPT-EEFR组合工艺的平均出水COD<45 mg/L、NH+4-N<5.0 mg/L、TP<0.75 mg/L、SS<20 mg/L,其对COD、NH+4-N、TN、TP及SS的平均去除率分别为80.3%、83.1%、50.2%、79.4%和88.1%,其中BPT对去除COD、NH+4-N、TN、TP及SS的贡献率分别为78%、25%、37%、53%及35%,EEFR的则为22%、75%、63%、47%及65%.同时,BPT-EEFR组合工艺还具有占地少、造价低、易于维护管理等优点,比较适合农村地区生活污水的处理.
