摘要
合理优化运行条件可有效缓解膜污染,降低制水成本。超滤反洗排水水质较好,水量较大,能够满足循环水补水要求,因此有效地回收超滤反洗排水,可以减轻污水处理的负担,有效解决废水处理量大、处理困难的实际问题,同时又可以节约循环水补充工业水量,有很好的经济效益。
Reasonable optimization of operating conditions can effectively alleviate membrane pollution and reduce water production costs.Ultrafiltration backwashing drainage has good water quality and a large amount of water,which can meet the requirements of circulating water replenishment.Therefore,effectively recycling ultrafiltration backwashing drainage can reduce the burden of sewage treatment,effectively solve the practical problems of large wastewater treatment volume and difficulty,and also save circulating water to supplement industrial water,with good economic benefits.
