摘要：
考察了电絮凝-膜分离反应器（ECMR）去除水中腐殖酸（HA）的效果。研究了不同电化学参数对腐殖酸去除率的影响、ECMR平板陶瓷膜和EC-MF平板陶瓷膜抑制膜污染的作用机制，并进行了比较。结果表明，在电流密度为10 A/m2、初始电导率1 000 μS/cm、初始pH=6、电解时间30 min、初始HA质量浓度5 mg/L时，ECMR工艺对水中HA的去除率为88.3%，ECMR平板陶瓷膜膜通量高于EC-MF平板陶瓷膜20%，HA去除率高8%，所用时间较短。

Abstract:
Humic acid(HA) removal by electrocoagulation-membrane reactor(ECMR) was investigated. The effects of different electrochemical parameters on the removal of HA were studied. Besides, the mechanism of antifouling by ECMR flat ceramic membrane and EC-MF flat ceramic membrane were compared. The results showed that under the current density 10 A/m2, initial conductivity 1 000 μS/cm, initial pH=6, electrolysis time of 30 min, and initial mass concentration of HA 5 mg/L, the HA removal reached 88.3%. The flux of ECMR flat ceramic membrane showed an enhancement by 20% than that of EC-MF flat ceramic membrane, the removal rate of humic acid was 8% higher, and the time used was shorter.
