Novel coagulant and preparation method thereof

The invention discloses a novel coagulant and a preparation method thereof. The coagulant is prepared from the following raw materials: polyaluminum ferric sulfate, silicate, PAC, PDMDAAC, titanium tetrachloride, MOFs, macromolecular chitosan and fly ash. The preparation method comprises the following steps: mixing and stirring the raw materials at normal temperature for 0.5-3 hours to obtain the novel coagulant. According to the coagulant used in the technical field of water treatment provided by the invention, the synergistic effect among medicaments is fully exerted, and the problems of poor treatment effect, high dosage, long settling time, poor stability and poor selectivity of the existing single coagulant are solved. 本发明公开了一种新型混凝剂及其制备方法，该混凝剂由以下原料组成：聚合硫酸铝铁、硅酸盐、PAC、PDMDAAC、四氯化钛、MOFs、高分子壳聚糖、粉煤灰；该制备方法包括将上述原料在常温下混合搅拌0.5-3h即可得到该新型混凝剂；本发明的提供一种水处理技术领域所用混凝剂，充分发挥了药剂之间的协同效应，解决现有单一混凝剂处理效果差，用量多，沉降时间久，稳定性差、选择能力差的问题。
