1 前言祥符水厂第一制水系统普通快滤池建于1989年,设计规模为14.5万m~3/d,采用陶瓷滤砖中阻力配水系统,单层石英砂滤料。经过十年的运行,固定陶瓷滤砖的铁压条已腐蚀,以及陶瓷滤砖的磨损,造成部分滤池的配水层损坏,导致承托层紊乱,滤池有漏砂现象,出水水质达不到要求,影响了生产。为了改善水质,适当增加产水量,祥符水厂决定对滤池进行改造。
1 Foreword Xiangfu Waterworks first water system ordinary fast filter was built in 1989, the design scale of 145000 m ~ 3 / d, the use of ceramic filter in the resistance distribution system, single-layer quartz sand filter. After ten years of operation, the iron bars of the fixed ceramic filter brick have been corroded and the wear of the ceramic filter brick has caused damage to the water distribution layer of some of the filters, resulting in disorder of the support layer, leakage of sand in the filter, Requirements, affecting the production. In order to improve the quality of water, increase the amount of water produced, Xiangfu water plant decided to transform the filter.
