多介质土壤渗滤系统去除农村污水中典型污染物的研究进展EI北大核心CSCD

多介质土壤渗滤(multi-soil-layering,MSL)系统作为低成本、易维护的农村污水处理技术成为新发展趋势。本文梳理了MSL系统的常见类型与运行原理,阐述了MSL系统去除农村污水中典型污染物的效果及其影响因素,从经济、社会与环境效益角度对MSL系统的应用现状与前景进行了评估,分析了其处理农村污水的优劣势与限制因子。指出应进一步优化MSL系统工艺,深入探究该系统对典型污染物的去除机制,加大其对抗生素耐药基因等新兴污染物的去除研究,为农村污水的高效处理与利用提供理论基础与技术支撑。

Research progress on removal of typical pollutants from rural sewage by multi-soil-layering system

Multi-soil-layering (MSL) system has become a new trend as a lower cost and maintenance-friendly technology for rural sewage treatment. This paper combs the common types and operating principles of the MSL system, and expounds the effect of the MSL system on removing typical pollutants in rural sewage and its influencing factors. The application status and prospect of the MSL system are evaluated from the perspective of economic, social and environmental benefits, and its advantages, disadvantages and limiting factors for rural sewage treatment are analyzed. It is pointed out that the MSL system process should be further optimized, the removal mechanism of typical pollutants should be deeply explored, and the removal of emerging pollutants such as antibiotic resistance genes should be increased, so as to provide theoretical basis and technical support for the efficient treatment and utilization of rural sewage.
