摘　　要：介绍了过滤技术在我国的应用,重点从滤料和反冲洗方式两方面论述其对过滤效果的影响。发现普通快滤池存在过滤周期短、出水水质不高等现象,通过总结成功改造滤池的方法和案例,得出合理选择滤料及相适应的反冲洗方式,并同时对集配水系统进行改造是延长过滤周期、提高滤后水水质关键的结论。Authors introduced the applications of granular filtration technology in China, with a focus on the influence of filter media and backwashing strategy on the filter performance. It was found that problems existed in conventional rapid filters such as too frequent backwashing, and high filter effluent turbidity. Based on the analysis of successful cases about filter reconstruction, this study concluded that the keys to prolonging the filtration cycle duration and improving the filtered water quality were choosing appropriate filter media and backwashing methods, at the same time, reforming water distribution systems.
