摘要
研究了陶瓷膜过滤啤酒洗瓶废碱液膜污染机理,提出了相应的清洗再生方案。对比研究了硝酸、盐酸、次氯酸钠、三聚磷酸钠4种清洗剂单独使用和复合使用的清洗再生效果。试验表明:0.20%硝酸+0.55%次氯酸钠+0.15%三聚磷酸钠复合清洗再生陶瓷膜,膜通量恢复率在85%以上。陶瓷膜连续运行两个月,清洗再生效果稳定,具有工程实用价值。
Membrane pollution mechanism had been researched in filtering the bottle washing waste alkali liquid by ceramic membrane and the corresponding cleaning regeneration schemes had also been put forward.The cleaning effect of nitric acid,hydrochloric acid,sodium hypochlorite and sodium tripoly phosphate on the ceramic membrane had been researched.Experiments show that the membrane flux recovery rate is more than 85% by the ceramic membrane of 0.20% nitric acid＋0.55% sodium hypochlorite＋0.15% sodium tripoly phosphate.Ceramic membrane is operated continuously in two months,the cleaning effect is stable and has practical value.
