摘要
采用孔径为200 nm的陶瓷膜处理微污染水,研究了试验工艺和常规工艺在不同条件下的膜清洗恢复情况,分析了反冲洗压力、反冲洗时间以及化学药剂对膜通量恢复的影响,并对试验工艺进行了长期、连续运行。结果表明:该试验工艺清洗情况运行良好;当反冲洗压力为0.60 MPa、反冲洗时间为40 s时,使用柠檬酸进行清洗时效果最好。
Membrane cleaning of ceramic membrane with pore size of 200 nm was used to treat the micro polluted water. The recovery of membrane cleaning of the test process and conventional processes under different conditions was studied. The effects of backwash pressure,backwash time and chemical reagents on the recovery of membrane flux were analyzed,and the test processed to carry on the long-term continuous operation. Experiment shows that process cleaning situation ran well.When the backwash pressure is 0. 60 MPa and the backwash time is 40 s,using citric acid,the cleaning effect is best.
