摘要
采用膜混凝反应器(MCR)对滦河原水进行中试研究,重点考察了对污染物的去除效果、膜污染及清洗方式。结果表明:MCR工艺的出水水质符合《城市供水水质标准》(CJ/T 206—2005)的要求;在高温、高藻期投加4 mg/L三氯化铁后,对CODMn的去除率为44.6%,若同时投加2mg/L的有效氯,则可使对CODMn的去除率提高到53%,且进水水质波动较大时出水水质仍保持稳定;该工艺对浊度、细菌有很好的去除效果;当膜在较高通量下运行时,采用化学在线清洗(即EFM操作)可有效清除膜污染物质,及时恢复膜的过滤性能。
A pilot study on the treatment of Luanhe River water was conducted by using membrane coagulation reactor （MCR）. The effects of pollutants removal, membrane fouling and cleaning methods were studied. The experimental results show that the treated water by MCR conforms to the requirements of Water Quality Standard for Urban Water Supply （ CJ/T 206 - 2005 ） issued by the Ministry of Construction. In the period of high temperature and algae, the CODMn removal rate is 44.6% at FeCl3 dosage of 4 mg/L, and increases to 53% when the effective chlorine of 2 mg,/L is added at the same time. And the treated water quality still keeps steady when the inlet water quality fluctuates largely. The turbidity and bacteria can be removed effectively by MCR. Enhanced flux maintenance （EFM） is an important method to decrease the membrane fouling under the condition of higher flux, which can restore the performance of membrane in time.
