| 中文摘要 |
| 采用混凝、粉末活性炭和UF膜分离的联用技术对黄浦江原水进行试验 ,结果表明 ,混凝、粉末活性炭可有效地去除溶解性有机物 .混凝处理主要去除大分子量的有机物 ,粉末活性炭主要去除低分子量的有机物 .混凝、粉末活性炭还能有效地去除三氯甲烷生成潜能 (THMFP) ,对于低分子量的THMFP ,混凝去除效果很差 ,而粉末活性炭去除很好 .试验还表明 ,混凝、粉末活性炭还可大大降低膜的滤饼层阻力 ,当混凝剂投加量为 4mg/L时 ,膜的滤饼层阻力最小 . |
| 英文摘要 |
| The experiments of ultrafiltration of Huangpu River water with coagulation and powered activated carbon (PAC) combinations was evaluated.The results showed that coagulation and PAC pretreatment effectively remove dissolved organic matters (DOM),of which coagulation removes high molecular weight (MW) DOM and PAC removes low MW DOM.Coagulation and PAC are effective treatment for removing Trihalomethane Formation Potential (THMFP).In terms of low MW THMEP,coagulation removes poorly and PAC removes effectively.The results also showed that addition of coagulant and PAC reduce cake resistance greatly.At coagulant dosage 4 mg/L (as Al),cake resistance was minimized. |
