Abstract:

In the running process of double-membrane system,it is found that membrane fouling,chemical damage,and improper operation are the main causes affecting the membrane life and economic benefits.Combined with the wastewater treatment process,the key points that need attention to the double membrane processes operation,as well as some typical troubleshooting are introduced.The discovery and treatment of metal,colloids,microorganisms,and organic pollutants are especially described in detail.

Key words: double-membrane system, key running points, advanced treatment, fault treatment

摘要：
