摘　　要：污水湿地处理系统是利用土壤、作物、微生物自然净化功能的生态工程技术。主要有水面湿地和渗滤湿地两种类型 ,在天津城市污水土地处理与利用系统研究的基础上 ,将两种工艺的优点进行优化组合 ,并应用于大港油田等污水湿地处理工程 ,运行结果表明 :将水面湿地和渗滤湿地工艺优化组合设计的示范工程 ,具有提高水力负荷、减少运行费用、节省工程投资、处理效果稳定等特点 ,有利于处理工程的长期稳定运行。Sewage wetland treatment system is an ecological technique by using natural purifying functions of soil,vegetation and microorganisms. It mainly consists of two types as water surface wetland system and infiltration wetland system. Advantages of these systems are combined and applied to sewage wetland system of Dagang oil field based on researches of national key project on science and technology of environmental protection. The results show that the design can improve hydraulic load,reduce operation cost,save investment and has a steady treatment effeiency. So,it is benefits for the long term and stead operation of such a type of treatment project.
