摘　　要：分散型污水处理难度大,人工快渗技术为其提供了一种适宜的可选技术,但该技术存在复氧效果差、脱氮除磷效率低、稳定性不佳等弊端。为解决这些问题,构建了改进型人工快渗系统,考察了其对分散型污水的处理性能。结果表明:采用多层复合有氧区的组合设置可实现高效复氧,获得较高的有机污染物和NH4+-N去除效率;缺氧区的改良使铁自养反硝化和氢自养反硝化成为可能,同时反硝化时间延长,保障了良好的TN去除效果;污水中的磷素污染物通过各类滤料的吸附及滤料表面微生物的转化而实现高效去除。通过逐步增大水力负荷的进水方式,可实现改进型人工快渗系统对污染物的稳定去除,为分散型污水的净化提供一条性能优良的新途径。The dispersed wastewater is difficult to treat.Artificial Rapid Infiltration Technology provides a suitable alternative technology,Therefore,it has some disadvantages,such as poor reoxygenation effect,low removal efficiency of nitrogen and phosphorus,and poor stability.In order to solve these problems,an improved artificial rapid infiltration system is constructed and its treatment performance for dispersed wastewater is investigated.The results show that efficient reoxygenation can be achieved by using the combination of multi-layer aerobic zone,and higher removal efficiency of organic pollutants and NH_(4)^(+)-N can be obtained.The improvement of anoxic zone makes it possible for iron and hydrogen autotrophic denitrification.At the same time,the denitrification time is extended to ensure the good removal effect of TN.Phosphorus pollutants in sewage can be effectively removed by adsorption of various filter materials and transformation of microorganisms on the surface of filter materials.By gradually increasing the water inlet mode of hydraulic load,the improved artificial rapid infiltration system can realize the stable removal of pollutants,and provide a new way with excellent performance for the purification of dispersed sewage.
