无机复合型高效净水剂的研制及应用

Synthesis and Application of Inorganic Complex-type High-efficient Coagulants

研制了多种无机复合型高效净水刘。通过搅拌实验评价了各种净水剂的净水性能,包括除浊率、沉降速度及对pH的适应范围等。结果表明,聚硅氯化铝和聚合氯化铁铝是两种较好的净水剂,具有矾花大、沉降快、余浊低等特点。聚硅氯化铝还有较宽的pH适应范围,聚合氯化铁铝对pH值相对敏感。

Many kinds of inorganic complex-type coagulants were prepared in this paper. Their water-purifying properties,such as removal rate of turbidity,sedimentation velocity,range of pH value for effective treatment,and so on, were evaluated. It was shown that poly-silicon aluminum chloride and polyferric aluminum chloride were better ones of which,with characteristics of big floe formation and thus,speed sedimentation and low turbidity of treated water. Futhermore,poly-silicon aluminum chloride is suitable to a wide range of pH of raw water while polyferric aluminum chloride is sensitive to pH value.
