污水灌溉与污水土地处理系统在公厕污水处理中的应用

位于昆明市下游的滇池，因受市区排放的生活污水、工业废水以及当地污水的影响，水污染问题十分突出，急需治理。污水灌溉与污水处理相结合的土地系统是一种可供选择的技术措施。本文阐述了将该系统用于公厕污水处理的工程构造型式与运行管理方式，建立了示范应用工程，开展了污染物去除效果研究和效益分析。结果表明，采用污水灌溉与污水土地处理系统处理公厕污水，处理后回用于厕所冲洗，可获得良好的污水处理效果，并可节约宝贵的淡水资源。该技术在实际应用中具有经济可行性。

Application of a wastewater land treatment system combined with wastewater irrigation

Due to domestic wastewater and industrial wastewater efflux from Kunming City and local cantaminant water, the Dianchi Lake has been badly polluted. From all kinds of technical measures dealing with pollution, the wastewater land treatment method is one of the choices. A wastewater land treatment system combined with landscape irrigation was applied to the treatment of wastewater from toilets in a park near the Dianchi Lake. A pilot project of the system was constructed and a mode of management and operation was established. The treated wastewater could be re-used for flushing toilets. The rates of pollutants removal were observed and the cost-benefit ratio was analyzed. The results show that the application of wastewater land treatment system combined with landscape irrigation in toilet wastewater treatment is feasible, in view of pollutants removal and economic utilization of water resources.
