摘要
采用混凝-气浮移动罩-超滤膜工艺处理太湖源水中试研究,考察了过滤周期、中间曝气时间、气水体积比、通量、排污时间对浸没式膜污染的影响。结果表明,在高温高藻期采用过滤周期1.5 h、中间曝气30 s、气水体积比4:1~5:1、通量30 L.m-.2h-1、排污时间25~30 s的工况能较好的减缓膜的污染。
A pilot study on the treatment of TaiHu Lake was conducted by coagulation-floatation movable hood filter-immersed ultrafiltration process.The effects of different filter cycle,aeration time,gas-water ratio,different flux and the discharging time were investigated.The results showed that when the raw water were in high algae and temperature,the conditions of the filter cycle of 1.5 h、the aeration time of 30 s、the gas-water ratio between4:1~5:1、the flux of 30 L·m-2·h-1、the discharging time between 25~30 s could alleviate the membrane fouling well.
