图们江是中朝俄三国的界河，随三国经济的发展，图们江流域受到不同程度的污染。现阶段，图们江流域生活污水治污比例非常低，其中，农村生活污水的治污需求非常迫切。研究开发适合图们江流域农村生活污水的处理技术，对改善图们江流域水环境，促进图们江流域国际合作与开发具有积极意义。.本项目拟采用Atmosphere-Exposed Biofilm处理图们江流域农村生活污水。通过分析不同运行条件下该技术对图们江流域农村生活污水的处理性能，阐明其净化机理；通过动力学研究及动力学参数的探求，建立适合图们江流域农村生活污水的基质降解动力学模型；通过Pilot plant的试运行，设计该技术在图们江流域的运行方案；并对该技术的能效性做出科学的评价。以此，研究开发适合图们江流域农村生活污水处理的Atmosphere-Exposed Biofilm，为该技术在图们江流域的推广与应用提供科学的理论依据。

The Tumen River is international river that it is located the junction of North Korea, China and Russia. With the economic of three country development, the Tumen River is polluted in different degrees. But in the present stage of Tumen River Basin domestic sewage pollution control is relatively low, especially the rural domestic sewage. Thus, research and development for treatment technology of Tumen River Basin rural domestic sewage, to improve the Tumen River Basin water environment, and promote international cooperation and development of the Tumen River Basin that has a positive meaning. .This project will use Atmosphere-Exposed Biofilm treatment of rural domestic sewage in Tumen River Basin. In various operation conditions using the technology in Tumen River Basin rural sewage treatment performance, illustrate the purifying mechanism; through the kinetics study and the search of kinetic parameters, will establish kinetic model of substrate decomposing in the Tumen River Basin rural domestic sewage ; through operation the pilot plant, will design the operation plan of the technology in Tumen River Basin; finally, will make a scientific evaluation for the technology of the energy efficiency. Through the above study, this project aims to research and development Atmosphere-Exposed Biofilm for treatment the Tumen River Basin rural domestic sewage, it is provide a theoretical basis that the technology popularization and application in Tumen River Basin.
