活性炭滤池

至2016年,全国活性炭深度处理工艺的应用规模约为2000万m3/d,约占城镇日供水总量的10%;活性炭滤池反冲洗水量约为200万m3/d,约占水厂日供水量的2%。活性炭滤池为矩形,钢筋混泥土结构,装配滤板,滤板上安装开口的塑料滤头,下向流过滤,滤板上面填放均质活性炭滤料层。

V型滤池

V型滤池为普遍采用的一种池型。V型滤池因两侧进水槽设计成V型而得名,滤池设有滤板,滤板上有预埋环,将细缝长柄滤头用丝扣装上。滤头上覆盖有均匀的滤砂层。其优点在于所用的均质滤料和前进的气、水反冲洗兼表面清扫技术。20世纪90年代以来,我国新建大、中型净水厂大多采用V型滤池过滤工艺,特别是广东省新建净水厂几乎全部采用V型滤池工艺。
