  • 摘要: 针对某水厂以超滤为核心的短流程水处理工艺,在通过聚氯乙烯(PVC)超滤膜之前选择不同投加量(5、10、15和20 mg/L)的高效聚合氯化铝(HPAC)对长江下游原水进行混凝处理。通过跨膜压差(TMP)增长趋势、CODMn的去除率以及混凝后的水质,可知HPAC的最优投加量为15 mg/L。在此投加量下,运用体积排阻色谱法分析原水、膜前水、膜后水中各相对分子质量有机物的变化,可以发现混凝去除有机物的效果要优于超滤截留的。继而将HPAC与另外4种常用混凝剂:硫酸铝(分析纯)、氯化铁(化学纯)、聚合氯化铝(PAC)、聚合硫酸铁进行对比,结果表明,在它们各自最优投加量下,HPAC能够更有效地减缓超滤膜TMP的增长率,从而降低膜污染。因此,认为HPAC是与PVC超滤合金膜契合效果最佳的混凝剂。
    Abstract: In order to find out the optimal dosage for the in-line coagulation combined with UF membrane process in a water treatment plant.Different dosages (5,10,15 and 20 mg/L) of high performance poly-aluminum chloride (HPAC) were performed in a pilot scale to treat the raw water from Yangtze River before PVC UF membrane filtration.According to the variations of TMP (trans-membrane pressure),the removal efficiency of CODMn and the water quality after coagulation,15 mg/L was determined as the optimal dosage of HPAC.In addition,HP-SEC was employed to examine the distribution of MW in raw water,coagulated and filtration effluent,indicating that the coagulation process could remove organic matter efficiently.After that,other four coagulants (Al2(SO4)3,FeCl3,PAC,PFS) were compared with HPAC,and it can be concluded that the incensement of TMP could be alleviated by using HPAC as a pretreatment.The results indicated that HPAC was the best coagulant which could prevent the membrane fouling.
