| 摘 要： | 针对小城镇生活污水水质、水量波动大的特性,在融合侧流除磷技术的基础上,开发了一种新型环流式活性污泥/生物膜组合工艺(简称CASBS).采用该工艺处理校园生活污水,在进水COD为111～606 mg/L,NH3-N为14.9～63.9 mg/L、TN为17.4～75.2 mg/L、TP为1.23～15.81 mg/L的情况下,出水COD、NH3-N、TN和TP的平均浓度分别为22.5、1.07、10.1和0.39mg/L.研究发现,CASBS特有的生物膜和交错布设的曝气系统,在环流反应器中形成了相对稳定的膜好氧区和非膜缺氧区,CASBS系统特殊的运行方式使之具备了排放剩余污泥除磷、排放厌氧富磷污水侧流除磷以及反硝化除磷等多种除磷方式,缓解了生物脱氮除磷效果对进水水质的依赖,从工艺技术优化的角度使CASBS系统具有了较强的抗冲击负荷能力.

| Abstract: | Aimed at the characteristics of wide fluctuation in quality and quantity of domestic sewage in small towns,a combined process of cyclic activated sludge and biofilm was developed based on integrating side stream phosphorus removal technology.In the treatment of campus domestic sewage by the combined process,the average concentrations of COD,NH3-N,TN and TP in effluent are 22.5 mg/L,1.07 mg/L,10.1 mg/L and 0.39 mg/L when the concentrations of COD,NH3-N,TN and TP in influent are 111 to 606 mg/L,14.9 to 63.9 m... |
