摘要:

探讨了终端超滤膜工艺对水中常见微囊藻毒素(MC-RR和MC-LR)的去除效率、机理和影响因素。结果表明:试验中超滤膜对微囊藻毒素的去除率很低,由最初的26%(MC-RR)、42%(MC-LR)分别降为2%、10%。氢键吸附和静电吸引可能是超滤膜去除水中微囊藻毒素主要机理。

Abstract:

The removal efficiency, mechanisms and influencing factors of microcystins(MC-RR and MC-LR) from deionized water by ultrafiltration membrane(UF)in terminal mode are discussed.The results show that the removal rate of microcystins by UF membrane is very low,from 26%(MC-RR)and 42%(MC-LR)to 2% and 10%,respectively.The hydrogen bonding adsorption and electrostatic attraction might be the dominant mechanisms of removing microcystins from water by UF membrane.

Key words: ultrafiltration membrane, microcystins, water treatment, adsorption
