摘　　要：比较了三氯化铁、硫酸铝和硫酸亚铁处理低温低浊水的效果,结果表明,三氯化铁除浊效果最好,硫酸铝次之,硫酸亚铁最差;在此基础上,通过投加活化硅酸作为助凝剂进一步进行实验,表明硫酸铝用活化硅酸作为助凝剂对于低温低浊水的处理具有相当好的效果,而三氯化铁对助凝剂反映不明显,因此,不适宜用其做助凝剂。Through the beaker experimentation, compared with the effects of FeCl3· 6H2O, Al2 （SO4）3H2O, FeSO4- 7H2O on dealing with low temperature and low turbidity, the results show that the FeCl3·6H2O removes the colloid most effectively, followed by Al2（SO4）·3H2O, the third is FeSO4·7H2O.on the basis ,through plunging into silicate-activated experiment, it fmds that Al2（SO4）·3H2O is the best flocculant on disposeing of low temperature and low turbidity,whereas, the effects of the FeCl3·6H2O is not distinctness, therefore,it is not fit to be flocculant.
