摘　　要：本研究以石英砂滤池为试验对象,探讨了不同石英砂粒径、砂滤池填层高度以及反冲洗方式对砂滤池过滤性能的影响,结果表明:当砂滤池采用200 mm厚粒径8~12 mm的粗砂+200 mm厚粒径4~8 mm的中砂+300 mm粒径2~4 mm的细砂的装填方式且采用气水联合反冲洗的方式,砂滤池的过滤性能最佳,出水SS降低率为56.8%~67.7%。在实际应用中,应根据项目的运行周期、出水要求等实际情况选择合适粒径的石英砂滤池。In this study,quartz sand filter was used as the test object,and the filtration performance of sand filter was studied by different quartz sand particle size,sand filter packing height and backwashing method.The results show that when the sand filter is filled with 200 mm thick quartz sand 8~12 mm in diameter,200 mm thick quartz sand 4~8 mm in diameter and 300 mm quartz sand 2~4 mm in diameter,air-water combined backwashing is used,the sand filter has the best filtration performance,and the effluent SS reduction rate is 56.8%~67.7%.In practical application,quartz sand filter with appropriate particle size should be selected according to the actual situation of project operation cycle and effluent requirements.
