摘要
采用A2/O和无阀滤池组合工艺处理昆明船舶公司生活区的污水,介绍了该工艺的特点和设计参数。运行结果表明,该工艺投资费用较小,运行成本低(1.1元/m3),出水水质达到了《城市污水再生利用城市杂用水水质》(GB/T18920—2002)的要求,可全部回用作该小区的绿化用水;系统的干污泥作为农田有机肥外运,实现了污泥资源化再利用的目的。实践证明,该工艺具有较强的实用性,为城市小区生活污水的再生回用提供了一种新的处理模式。
The combined process of A^2/O and valveless filter was used to treat sewage from the living quarters of Kunming Shipping Company. The characteristics and design parameters of this process were introduced. The operation results show that the process has less investment and low operation cost （ 1.1 yuan/m^3 ）. The effluent, whose quality can meet the requirements of Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption （GB/T 18920 -2002）, can be reused for greening of this residential area. The dried sludge from the system, used as organic manure on arable land is transported out, the aim of resource reuse is achieved. The practice indicates that the process has higher practicability and provides a new method for reclamation and reuse of domestic sewage from urban residential areas.
