浸没式超滤膜替代砂滤处理东江水的中试研究
Pilot study of immersed UF membrane substituted for sand filtration in drinking water treatment of Dongjiang River
摘要
Abstract
To focus on the upgrade and improvement of the conventional drinking water treatment processes, the effluent quality of immersed ultrafiltration( UF) for the treatment of Dongjiang River was investigated, and the operation conditions under higher flux were studied. Results show that effluent turbidity of UF which is lower than that of sand filter during the same period, was not affected by the quality of source water, and the tu-bidity of which were maintained less than 0. 1 NTU. But the removal of organics by UF was almost the same as sand filter. Tests on optimization of operating conditions show that membrane filtration cycle should be shortened appropriately under the condition of a relatively high flux. Effective physical cleaning and auxiliary to short-term enhanced flux maintenance (EFM) cleaning would ensure the long-term stable operation of membrane filtration.关键词
