摘要:

由于池体滤板破损、进出水流向与反洗流向相同,快滤池无法满足中水回用项目的要求。针对快滤池存在的问题,采取了相应的改造措施,消除了超滤及反渗透装置因预处理效果不佳而出现的膜污堵现象,不仅节约了化学清洗超滤和反渗透装置的原材料,而且增大了废水回用率,外排水量也控制在规定的范围内,有效降低了排污费用。

Abstract:

Because the filter plate of the pool body is damaged, the flow direction of the inlet and outlet water is the same as that of the backwashing, the rapid filter cannot meet the requirements of the reclaimed water reuse project. In connection with the existing problems of the rapid filter, the corresponding modification measures are taken to eliminate the membrane fouling phenomenon of the ultrafiltration and reverse osmosis devices due to poor pretreatment effect, which has not only saved the raw materials of the chemical cleaning ultrafiltration and reverse osmosis devices, but also increased the wastewater reuse rate, the external drainage volume is also controlled within the specified range, and the sewage discharge cost is effectively reduced.
