生物-生态组合系统处理分散生活污水应用研究

Research on Decentralized Domestic Sewage Treatment by Combined Biological and Ecological System

介绍了一种基于生态工程技术(生物-人工湿地)的低费用、低能耗的分散式污水处理系统,并对该系统的运行效果进行了长期监测,结果表明:该系统对CODCr、NH4+-N、TP、SS等污染物具有很好的去除效果,出水水质优于国家城镇污水处理厂的一级排放标准和《再生水回用于景观水体的水质标准》(CJ/T 95—2000).在分析该系统实际运行问题的基础上指出:作为一种全新的污水处理模式,分散式污水生态处理应在优化群集设计的前提下向小规模、设备化方向发展.

This paper introduced mainly an economical decentralized domestic sewage treatment system based on ecological engineering （biological and artificial wet land） . Through long period monitoring, the results show that the combined system could effectively remove CODCr, NH4^＋ -N, TP and SS. That meant the contents of CODCr, NH4＋^-N, TP and SS would be better than the Ⅰ level according to the Emission Standard of Town Wastewater Treatment Plant of China and the level of the Standard of Sight Reuse Water. It comes to a conclusion that as a new wastewater treatment technology, it would develop in ways of small scale and equipment.
