摘要
采用不投加任何药剂的一级硝化—反硝化工艺，研究了“活性污泥法＋缺氧变速生物滤池”城市污水深度处理系统．通过正交试验确定系统最佳运行条件，此时系统ＣＯＤｃｒ去除率为９１．１％，缺氧变速生物滤池ＮＯｘ－Ｎ去除率为７４．４％．系统出水可用于农田灌溉，消毒后可用作城市生活杂用水．
The “Activated slodge process+anoxic variable velocity Biological Filtcr” system of advanced municipal sewage treatment, with no cxternal alkaline and organic matter added has been studied in this paper. The optimum operating condition of cxperimental system has been determined by orthogonal experiment method. It is HRT 1=4h, HRT 2=3 52h, and the maximnm COD cr removal effieiency 91 1%, the maximnm NO x-N removal efficicncy 74 4% in optimnm operating condition. The effluent water of the system can be used for irrigation and be considered of municipal use for planting, washing and so on when is disinfected.
