摘要
采用多种化学清洗剂对处理循环水排污水过程中被污染的超滤膜进行了清洗。结果表明,在被污染的膜丝内,悬浮物和无机盐相互覆盖,用次氯酸钠和Aquaklean7314对超滤膜进行交替清洗可以获得较好的清洗效果。
The cleaning of utrafiltration membrane polluted in the blowoff process of circulating water treatment equipment has carried out by using several kinds of cleaning agents. Results show that the suspended solids and inorganic salts overlaid on each other in the pollutted membrane silks. The ultrafiltration membrane has been cleaned by alternately using the sodium hypochlorite and the Aquak-lean 7314,obtaining comparatively good effectiveness of cleaning.
