【摘要】 用聚硅硫酸铝处理黄浦江原水进行中试研究,以解决冬季低温时硫酸铝混凝效果不佳的问题,结果表明:与硫酸铝相比,在相同投加量情况下,聚硅硫酸铝沉淀池出水浊度可降低50%;在投加量为硫酸铝1/2情况下,聚硅硫酸铝沉淀池出水的浊度仍低于硫酸铝沉淀池出水;残留的铝含量降低,而残留硅的含量没有增加,但投加聚硅硫酸铝会导致滤池水头损失增加。更多还原

【Abstract】 Pilot study on aluminium sulphate polysilicate for Huangpu raw water treatment is discussed here.The results show settled water turbidity for aluminium sulphate polysilicate is 50% lower than that for aluminium sulphate at the same dosage;dosage of aluminium sulphate polysilicate can be reduced 50% in comparison with aluminium sulphate at appropriate settled water turbidity;application of aluminium sulphate polysilicate can decrease residual aluminium content.But water head loss of filter for aluminium sulphate polysilicate application will grow quicker than that for aluminium sulphate.更多还原
