微滤膜与混凝集成反应器处理微污染水源水研究

Membrane Coagulation Reactor for Micro-polluted Raw Water Treatment

采用微滤膜与混凝集成反应器（简称膜混凝反应器，MCR）处理某湖水，规模为0．5m^3／h。结果表明：当氯化铁投加量为30～50mg／L、粉末炭投加量为20～30mg／L时，MCR对微污染水中浊度、有机物和细菌具有良好的去除效果；试验期间出水浊度和菌落总数分别低于0．3NTU和30CFU／mL；当原水为《地表水环境质量标准》（GB3838-2002）规定的Ⅴ类水时，出水水质基本可以满足《生活饮用水卫生标准》（GB5749-2006）的要求；当原水是劣Ⅴ类水时，出水水质接近饮用水标准。

Membrane coagulation reactor （MCR） was used for the treatment of lake water. The capacity of the reactor was 0.5 m^3/h. The results indicated that turbidity, bacteria and organic pollutants were effectively removed when dosages of ferric chloride and powdered activated carbon （PAC） were 30 to 50 mg/L and 20 to 30 mg/L, respectively. Turbidity and total bacterial count in finished water were less than 0.3 NTU and 30 CFU/mL, respectively. When the raw water was under the V criteria specified in the Environmental met the requirement not meet V criteria, Quality Standards for Surface Water （GB 3838 -2002 ） , the finished water quality of Standards.for Drinking Water Quality （ GB 5749 - 2006 ）. When the raw water did the finished water quality was close to the standard.
