Abstract

本发明公开了一种新型絮凝剂。该新型絮凝剂由粉煤灰、淀粉、氯化铁、氧化钠、氯化锌、硫酸铝、聚丙烯酸钠、聚乙烯吡咯烷酮、聚硅酸铁组成。本发明絮凝剂化学性能稳定，用量少，投料范围宽，沉淀形成时间短，形态粗大易于沉降，可缩短水样在处理系统中的停留时间等，因而提高了系统的处理能力，对处理水的pH值基本无影响。

Description

一种新型絮凝剂
技术领域
本发明涉及一种化学制剂，具体是一种絮凝剂，属于水处理技术领域。
背景技术
在水处理过程张，絮凝剂主要使带有正（负）电性的基团中和一些水中带有负（正）电性难于分离的颗粒，降低其电势，使其处于不稳定状态，并利用其聚合性质使得这些颗粒集中，并通过物理或者化学方法分离出来。
絮凝剂主要分无机、有机两大类，此外还有微生物絮凝剂。无机絮凝剂价格便宜，但对人类健康和生态环境会产生不利影响；有机高分子絮凝剂虽然用量少，浮渣产量少，絮凝能力强，絮体容易分离，除油及除悬浮物效果好，但这类高聚物的残余单体容易致崎、致癌、致突变，因而使其应用范围受到限制；微生物絮凝剂因不存在二次污染，使用方便，应用前景被看好。
发明内容
本发明的目的是提供一种新型絮凝剂。
本发明的技术方案如下：一种新型絮凝剂，由粉煤灰、淀粉、氯化铁、氧化钠、氯化锌、硫酸铝、聚丙烯酸钠、聚乙烯吡咯烷酮、聚硅酸铁组成。
优选的原料配比是：粉煤灰25~35份、淀粉20~40份、氯化铁5~10份、氧化钠4~10、氯化锌3~12份、硫酸铝15~30份、聚丙烯酸钠10~20份、聚乙烯吡咯烷酮10~15份、聚硅酸铁5~12份。
本发明絮凝剂化学性能稳定，用量少，投料范围宽，沉淀形成时间短，形态粗大易于沉降，可缩短水样在处理系统中的停留时间等，因而提高了系统的处理能力，对处理水的pH值基本无影响。
