| 摘 要： | 以微絮凝和微滤作为反渗透的预处理工艺,采用连续流微滤-反渗透集成膜工艺深度处理城市污水厂二级生物处理出水,比较了投加聚合氯化铝和氯化铁进行微絮凝控制微滤膜污染的效果.结果表明,投加氯化铁对微滤膜污染具有更好的控制效果;微滤出水浊度＜0.5 NTU,对TOC的去除率为50%左右,对UV260的去除率＜30%. |

| Abstract: | Micro-flocculation and microfiltration (MF) processes were used for pretreatment of reverse osmosis (RO), and the combined membrane of continuous flow MF/RO was used for advanced treatment of secondary effluent from urban wastewater treatment plant. Polyaluminum chloride and ferric chloride were used as flocculant for controlling the MF membrane fouling. By comparison, ferric chloride was more efficient, and the result shows that the effluent turbidity is less than 0.5 NTU, and the removal rate of TOC is about 50%, and UV 260 less than 30%. |
| Keywords: | microfiltration reverse osmosis micro-flocculation advanced treatment secondary effluent |
