摘　　要：在国家环保要求日益严格的形势下,针对目前公路服务区污水处理领域存在的运行成本高、管理养护复杂和设备故障率高等实际问题,将多介质生物滤池和生态湿地有机组合形成多介质生物生态协同处理技术,并开展了工程实践应用。结果表明,该技术运行效果稳定,对COD、NH3-N、TN和TP的平均去除率分别达到94.22%、94.12%、85.42%和82.65%,处理出水水质优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,直接运行成本仅为0.185元/m^3。Under the situation of increasingly stringent environmental requirements in China, there has been problems such as high cost, complex management and maintenance, as well as high equipment failure rates of most domestic sewage treatment systems in expressway service areas. To solve these prob- lems, multi-media biological filter and ecological wetland are combined and put into engineering practice. Results showed stable operating effect with direct operation cost of only 0. 185 Yuan/m3. The average re- moval efficiency of COD, NH3 - N, TN and TP was 94.22% , 94.12% , 85.42% and 82.65% , respec- tively. The effluent of the sewage treatment project could meet first level A criteria of Discharge Standard of Pollutants of Municipal Wastewater Treatment Plant （ GB 18918 - 2002 ）.
