摘要:

采用聚合氯化铁(PFC)作为混凝剂对腐殖酸-高岭土模拟水样进行混凝-超滤-氯消毒处理,分析混凝絮体特性和超滤处理过程对消毒副产物前驱物的生成趋势的影响。结果表明,PFC混凝效果随着投加量的增大而增强;投加量为12 mg/L时,酸性条件有利于增强混凝效果;超滤过程可以去除混凝出水中的大分子有机物,但对快速反应物的去除效果却不明显;在絮体粒径>500μm的范围内,絮体粒径的增大有利于快速反应物的去除,从而降低了消毒副产物的生成潜能。

Abstract:

Polyferric chloride(PFC) has been used as coagulant for treating humic acid and kaolin simulated water samples by the combined coagulation-ultrafiltration-disinfection process. The impacts of coagulation floc characteristics and the ultrafiltration treatment process on the forming tendency of disinfection by-products and precursors are analyzed. The results indicate that the PFC coagulation effect is enhanced with the increase of PFC dosages. When the PFC dosage is 12 mg/L,the acidic condition is advantageous to the enhancement of coagulation effect. The process of ultrafiltration can effectively remove the macromolecular organics from the coagulated effluent water,but the removing effect on the fast reactants is not obvious. The increase of floc size is advantageous to the removal of fast reactants when the floc size is in the range of larger than 500 μm,so as to reduce the formation potential of disinfection by-products.

Key words: polyferric chloride, humic acid, disinfection by-products, precursors, floc characteristics
