摘　　要：通过试验探讨了滤池关闭对生物过滤的影响。结果表明 :短期的滤池关闭对生物过滤影响较小 ,滤池在重新启动后的 2～ 6h内就能基本恢复到关闭前的处理效果 ;长期的滤池关闭对单层石英砂滤料生物过滤有较大的影响 ,但对活性炭 石英砂双层滤料生物过滤影响较小。The effects on the operation of bio-filtration in case of filter closedown are discussed on the basis of experimental research.It was observed that in case of short-time shutdown,the normal state of filtration could recover at 2 to 6 hours.since re-startup,In case of long-time shutdown more serious effects could be observed for single layer sand filter.but no such effect was found for the filter with double-layer media of composite bed of activated carbon and quartz sand.
