摘　　要：针对早期建设的水厂V型滤池运行中出现的滤后水浑浊度超标等问题,检测了反冲强度、滤砂含泥量等一系列参数,找出了滤池运行工况不佳的原因。在此基础上,采取了相应的改造措施,大幅降低了滤后水浑浊度,取得了满意的效果。For the turbidity of water which from early built V-type filters was out of standard frequently, some factors such as back wash strength, soil content of sand which impact water quality were measured. Several improvements have been taken, the results show that the turbidity of filtered water is decreased sharply compare with before.
