聚硅硫酸铝在水处理中的性能研究

目的研究聚硅硫酸铝 (PASS) 在水处理中的性能. 方法就原水温度、浊度、 pH 值对自制的絮凝剂 PASS 絮凝性能的影响及处理前后原水 pH 值改变量进行烧杯搅拌实验. 结果聚硅硫酸铝具有适应的水温及 pH 值范围宽, 处理前后 pH 值变化小等优越性. 结论聚硅硫酸铝比硫酸铝和聚合硫酸铝具有更好的絮凝效果.

Study on Properties of Polymeric Aluminum Sulfate-silicate for Water Treatment

Aim\ To study the properties of the flocclant polymeric aluminum silicate sulfate (PASS) in water treatment. Methods\ The efficiency of removing turbidity by self prepared PASS under different temperature, turbidity , pH value of the water sample and the change of pH value of water sample before and after treatment were compared by the jar experiments.Results\ PASS had the characters of wider working pH value and the temperature range, less changes of pH of water sample before and after treatment were observed. Conclusion\ The results of study indicate that PASS had advantageous properties for the water treatment.
