住宅小区中水净化工艺设计摘 要我国面临着严重的水资源短缺和水环境污染问题。日益严重的水量型和水质型缺水不仅严重困扰着人民的生活，也成为影响和制约我国经济可持续进展的主要因素之一。随着人口的增长和房地产事业的进展，城市住宅小区的用水量和污水排放量越来越大，建立住宅小区中水回用系统，将居民生活污水经集流、水处理后回用于小区的冲厕、绿化等，既可以大幅度减少小区周围水环境的污染负荷，又可开辟可靠、稳定的第二水源，因而具有重大的讨论和应用价值。目前，我国大多数城镇住宅小区建设中水系统的条件已基本具备，并日趋完善。随着城镇住宅小区的规模化以及水处理技术的进展，中水系统的投资和运行费用将大幅度降低；小区物业管理的兴起和完善也为小区中水系统的投资回报奠定了基础。本文通过对多种中水净化工艺进行综合比较，采纳“生物接触氧化法＋混凝沉淀”作为主体工艺对住宅小区杂排水进行处理，并对小区地埋式中水净化站进行设计计算。出水水质可达到国家生活杂用水水质标准(CJ/T48-1999)。关键词：杂排水，生物接触氧化法，混凝沉淀，中水回用Design on Reclaimed Water Treatment Processfor Residential areaAbstractChina is facing increasingly serious problems of water shortage and water pollution. They not only make people’s life difficult, but also become one of the main factors which affect and restrict the sustainable development of our economy. As the growth of population and the development of real estate, the amount of running water consumption and sewage discharging are becoming larger and larger in urban residential areas. Building up reclaimed water systems for residential areas, treating the collected sewage, and then using the reclaimed water for flushing and virescence, can efficiently reduce the water pollution load around those districts. More important, it is a good way to open up the second reliable and stable water source. So it is of great significance on research and application. At present, the majority of our urban residential areas are ready to build up...
