超滤技术处理高盐卤水中试实验
Pilot treatment of high salt brine by ultrafiltration technology
摘要
Abstract
"Self-cleaning filter+ultrafiltration system"combination technology as a pretreatment process of nanofiltration units was used to treat high salinity of underground brine from ShanDong Ocean Chemical Group Ltd. The technological parameters of membrane flux, washing frequency are optimized by using external pressure type hollow fiber ultrafiltration membranes from Tianjin Motimo Membrane Technology Co Ltd. The selection of effect of CEB cleaning for controlling the membrane fouling is discussed according to the theoretical and experimental data analysis. The cleaning agent is optimized. The results showed that membrane flux of 40 L/(m2·h) is the best membrane flux, under this flux, the membrane equipment can keep a long-term stable operation and the water recovery rate is stable around 95%;CEB cleaning effect is good, the equipment has a high stability, and recovery rate is stable for a long time. No algae is detected in the UF effluent, which show the combination technology has a good effect on algae removal. The effluent turbidity water was under 0.1 NTU, SDI15 was less than 3, the average effluent TOC was 11.7 mg/L, this satifies the requirements of subsequent nanofiltration into the water.关键词
