固废基无机高分子混凝剂研究进展及改进途径

无机高分子复合型混凝剂具有优越的絮凝能力，但目前于基于固废资源化利用制备无机高分子复合混凝剂的相关研究缺乏系统性。本文介绍了三类固废基无机高分子复合混凝剂的制备工艺、性质特点，简述了其在水处理领域的应用、作用机理及存在的问题，并结合新型无机高分子复合混凝剂的研究进展，分析了固废基无机高分子复合混凝剂的发展方向。根据已有结果，文中指出需要从固废原料的化学组成，建立全面的固废资源，优化不同来源固废基无机高分子复合混凝剂的制备工艺；其次指出应进行混凝剂的物耗、能耗等技术经济分析，促进其规模化生产使用；并提出对污泥固废应进行循环资源化利用，关注制备过程中产生的无机盐，避免对水质的不良影响；最后表明，应加强混凝剂功能化研究，开发具有协同效应的固废基无机高分子复合混凝剂。

Progress and improvement of inorganic polymer coagulant based on solid waste

Inorganic polymer composite coagulants have superior flocculation ability, but few studies are on the preparation of inorganic polymer composite coagulants based on solid waste recycling. This paper introduced the preparation technology, properties and characteristics of three inorganic polymer composite coagulants based on solid waste, briefly described their application in water treatment, the interaction mechanism and existing problems, and combined with the research progress of new inorganic polymer composite coagulants to analyze the development direction of inorganic polymer composite coagulants based on solid waste. According to the current results, it was necessary to establish a comprehensive solid waste resource from the chemical composition of solid waste raw materials and optimize the inorganic polymer composite coagulant preparation process from different sources. Secondly, it was concluded that the technical and economic analysis should be carried out on the material and energy consumption of the coagulant to promote its large-scale production and use. It was suggested that the solid waste of sludge should be recycled and the inorganic salt produced in the preparation process should be paid attention to avoid the adverse effect on water quality. The results showed that it was necessary to strengthen the study of coagulant functionalization and develop the solid waste inorganic polymer composite coagulant with a synergistic effect.
