Description

生活污水处理剂及其制备方法
技术领域
本发明属于处理剂技术领域，具体涉及一种生活污水处理剂及其制备方法。
背景技术
污水处理厂是水环境污染治理的主要功能承担者，在净化水污染方面发挥着关键作用。截至2014年底，全国投运的城镇污水处理设施接近4000座，总设计处理能力超过500亿m3/d。污水处理厂的一个突出特点就是水池种类多，面积大：调节池、酸化水解池、初沉池、曝气沉砂池、生化池、二级沉池、高密度沉淀池、砂滤池、紫外消毒池等。在生产过程中，由于污染物种类成分复杂，污水中的金属离子、无机成分、有机物及微生物分泌物的相互作用，结果在池壁上出现了黑色污垢沉积物，导致出水的水质变差，影响生产运行。因此，在日常运行过程中，要经常定期或不定期地去除这些污垢。
传统使用的去垢剂有漂白粉、漂白精、硫酸铜、新洁尔灭等，但是这些去垢剂大部分为强酸、强碱等成分，存在腐蚀性强、挥发性大、操作难度高，耗时长，不仅给操作人员身心健康带领不利影响，而且清洗效果差，清洗时间长，清洗效率低，最终影响生产运行。因此，有必要研制能够高效去除污水处理厂池壁污垢的清洁剂。
发明内容
为解决现有技术存在的问题，本发明提出一种生活污水处理剂，该处理剂能有效吸附污水中的颗粒物，同时迅速将水中的污垢沉淀和水面上的油去除，去除后的水其级别达到实验室用水一级。
本发明的技术方案是这样实现的：
一种生活污水处理剂，按照重量份数计算，包括以下组分：
硅酸钠5～10份、氯酸钠5～10份、麦饭石20～40份、矿渣20～30份、木质素磺酸钠20～30份、壳聚糖10～15份、聚乙烯吡咯烷酮10～20份、聚硅硫酸铝5～10份、聚合三氯化铁10～20份、膦酸盐10～20份、乙二胺四甲叉膦酸10～20份、去离子水60～120份。
进一步，按照重量份数计算，包括以下组分：
硅酸钠7份、氯酸钠7份、麦饭石30份、矿渣25份、木质素磺酸钠25份、壳聚糖12份、聚乙烯吡咯烷酮15份、聚硅硫酸铝7份、聚合三氯化铁15份、膦酸盐15份、乙二胺四甲叉膦酸15份、去离子水90份。
本发明的另一目的是提供一种生活污水处理剂的制备方法，包括以下步骤：
1)按照上述配比，称取麦饭石与矿渣进行粉碎，然后研磨得到粉末；
2)按照上述配比，称取硅酸钠、氯酸钠、木质素磺酸钠、壳聚糖、聚乙烯吡咯烷酮、聚硅硫酸铝与聚合三氯化铁进行混合搅拌，然后加入去离子水与步骤1)得到粉末进行搅拌均匀，得到液体混合物；
3)将步骤2)得到的混合物水浴加热至40～60℃，然后加入膦酸盐与乙二胺四甲叉膦酸，边加边搅拌均匀，加料结束后缓慢降温至室温，然后用pH调节剂调节pH至7.5～9，即可。
本发明的有益效果：
本发明通过麦饭石与矿渣作为吸附材料，能够在不对水造成污染的前提下，迅速将水中的污垢沉淀和水面上的油吸附，同时能够快速将水面上的油层吸附。在不采用聚丙烯酰胺(常用污水处理剂)的前提下，通过聚合三氯化铁、壳聚糖、膦酸盐以及乙二胺四甲叉膦酸协同作用，将水中的细菌、微生物等进行灭杀，达到将污水净化成能够使用的标准用水。
