摘要:- 羅橋水廠改造工程采用浸沒式超濾膜工藝,將原有產(chǎn)水量為1×104 m3/d的砂濾池原位改造成產(chǎn)水量為2×104 m3/d的虹吸超濾膜濾池,水質(zhì)水量達(dá)到了設(shè)計要求。該項(xiàng)目的運(yùn)行情況良好,膜通量大,截留精度高,當(dāng)產(chǎn)水量為設(shè)計產(chǎn)水量(2×104 m3/d)時,跨膜壓差為5 kPa,膜通量為35 L/(m2·h)。在用水高峰期產(chǎn)水量為3×104 m3/d時,膜通量為50.4 L/(m2·h),跨膜壓差為10 kPa。該系統(tǒng)水回收率超過96%,沒有新增占地,實(shí)現(xiàn)低液位差虹吸產(chǎn)水,產(chǎn)水不用水泵抽吸,系統(tǒng)運(yùn)行穩(wěn)定,能耗低,費(fèi)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.
