摘要
Abstract
Taking a steel company's reclaimed water reuse system as an example,the contamination types and pollutant compositions of ultrafiltration membranes were analyzed.Meanwhile,the EFM method and the optimal cleaning dosage were studied.The results showed that the ultrafiltration membrane contamination was mainly organic pollutants and a small amount of inorganic pollutants.EFM cleaning is based on NaClO cleaning,and citric acid cleaning is used intermittently.The optimal dosage of NaClO is 800 mg/L,and the op-timal dosage of citric acid is 600 mg/L.The cleaning method and the optimal dosage of chemicals can effectively improve the safe and stable operation of the ultrafiltration system for a long period of time,which has certain reference significance for the same industry.关键词
