基于生物-生态耦合工艺的农村生活污水处理研究
开发低投资、低能耗、低维护的生活污水处理工艺是解决农村污水处理问题的关键。采用无动力升流式厌氧生物滤池(UAF)与潜流式人工湿地(SFW)耦合工艺处理农村生活污水,考察了耦合工艺在不同水力停留时间(HRT)下对生活污水的处理效果,并通过增加SFW内的植株密度改善脱氮除磷效果。结果表明:UAF与SFW耦合工艺无动力消耗,免维护,适合农村地区的生活污水处理,对氮、磷的去除主要依靠SFW阶段完成,通过增加芦苇的植株密度可以明显增强SFW内生物的脱氮除磷能力,并保证UAF与SFW耦合工艺的处理性能稳定在较高水平。在t(HRT)UAF=18h,t(HRT)SFW=3d的条件下,UAF与SFW耦合工艺出水...

| Summary: | 开发低投资、低能耗、低维护的生活污水处理工艺是解决农村污水处理问题的关键。采用无动力升流式厌氧生物滤池(UAF)与潜流式人工湿地(SFW)耦合工艺处理农村生活污水,考察了耦合工艺在不同水力停留时间(HRT)下对生活污水的处理效果,并通过增加SFW内的植株密度改善脱氮除磷效果。结果表明:UAF与SFW耦合工艺无动力消耗,免维护,适合农村地区的生活污水处理,对氮、磷的去除主要依靠SFW阶段完成,通过增加芦苇的植株密度可以明显增强SFW内生物的脱氮除磷能力,并保证UAF与SFW耦合工艺的处理性能稳定在较高水平。在t(HRT)UAF=18h,t(HRT)SFW=3d的条件下,UAF与SFW耦合工艺出水COD、氨氮、总氮、总磷的平均质量浓度分别为44.07,4.25,13.36和0.44mg/L,达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准。 |
