| 摘 要： | 针对水厂滤池低负荷下滤后水浊度远低于标准要求、水头损失小、截污滤层浅、反冲洗时间较长、耗水耗电量大的问题,采用增加滤池负荷、延长过滤周期并调整反冲洗时间的优化方案.试验结果表明:在增大滤池负荷的基础上,将过滤周期由目前的55 h延长到71 h,水头损失随时间增加较快,截污滤层下移,滤层截污效能提高.不同反冲洗条件下的排... |

| Abstract: | Considering the lower turbidity,small head loss,shallow distribution of interception suspended solids,long backwash time and high energy consuming under low load,an optimization scheme by means of increasing filtration load,prolonging filtration cycle and adjusting the distribution time of backwash was brought forward.The experiment results showed that the head loss could be increased rapidly with the filtration time based on increasing filtration tank load and prolonging the filtration from 55 h at present... |
