新型PSAZ-CTS的制备及对松花江水的絮凝效果研究

Study on the Preparation for a New Kind of PSAZ-CTS and Its Flocculation Capability to Songhua River Water

摘要:

以硅酸钠、硫酸锌、硫酸铝、壳聚糖为原料制备了PSAZ-CTS复合型絮凝剂，并对其制备条件进行优化。实验结果表明：当n(Al Zn)/n(Si)=1.0，n(Al)/n(Zn)=5，(Al Zn)与壳聚糖的质量比为4，反应温度为40℃，pH为1.4时，制备的PSAZ-CTS复合絮凝剂对于松花江江水净水效果良好，特别是能够处理低温松花江水。最后采用扫描电镜对PSAZ-CTS进行表征分析。

Abstract:

In this experiment, Using sodium silicate, zinc sulfate, aluminum sulfate, chitosan to Synthesize poly-silicate aluminum zinc-chitosan, and optimizing the preparation conditions at the same time. .The result showed that the prepared PSAZ-CTS had best flocculation performance when n(Al+Zn)/n(Si)=1, n(Al)/n(Zn)=5, m(Al+Zn)/m(CTS)=4, pH=1.40, in the condition of 40 ℃ experimental environment. The turbidity removal rate of the water from Songhua river reached a high level, even at a low temperature had a better treatment effect. Finally, The morphology of PSAZ-CTS flocculant was observed by an scanning electron microscopy. Key words: flocculant；PSAZ-CTS；preparation；turbidity；chroma；SEM
