双层均匀滤料滤池在生产上的运用

PRACTICAL APPLICATION OF UNIFORM GRANULAR DOUBLE-BED FILTERS

柳州市自来水公司与重庆建筑工程学院等单位合作,在柳南区水厂进行了双层均匀滤料滤池的生产性试验。试验结果表明:陶粒-石英砂双层均匀滤料滤池的出水优于石英砂滤池的出水,前者的滤速和工作周期分别是后者的1.5倍与2～3倍。作者还对该滤池在运行过程中出现的问题进行了讨论,并提出了改进建议。

A productive experiments of filters filled with dual- layer of uniform granular media was performed in Liunan Waterworks in Liuzhou,by cooperation of Liuzhou Watersupply Company and Chongqing Civil Engineering Institute. The result shows that the quality of water produced by ceramsite-quartz sand filter was better than that by quartz sand bed. The filtration speed and the operation cycle of the former was 1. 5 and 2 to 3 times than the latter respectively. Some problems occured in filter operation was discussed and suggestions to improve its performance proposed by the author.
