摘要:
罗桥水厂改造工程采用浸没式超滤膜工艺,将原有产水量为1×104 m3/d的砂滤池原位改造成产水量为2×104 m3/d的虹吸超滤膜滤池,水质水量达到了设计要求。该项目的运行情况良好,膜通量大,截留精度高,当产水量为设计产水量(2×104 m3/d)时,跨膜压差为5 kPa,膜通量为35 L/(m2·h)。在用水高峰期产水量为3×104 m3/d时,膜通量为50.4 L/(m2·h),跨膜压差为10 kPa。该系统水回收率超过96%,没有新增占地,实现低液位差虹吸产水,产水不用水泵抽吸,系统运行稳定,能耗低,费用省。
Abstract:
The siphon submerged ultrafiltration membrane process with the capacity of 2×104 m3/d was adopted to reconstruct the original sand filter with the capacity of 1×104 m3/d in Luoqiao waterworks. The system has operated well, with large membrane flux and high interception accuracy. At the designing water yield of 2×104 m3/d, the transmembrane pressure was 5 kPa and the membrane flux was 35 L/(m2·h). At the peak-hours water yield of 3×104 m3/d, the membrane flux was 50.4 L/(m2·h), and the transmembrane pressure was 10 kPa. The water recovery exceeded 96%. The system produced water using the method of siphon in low liquid level, without additional land occupation and water pump. The system had run stably with low energy consumption and operating costs.
