煤泥水处理方法研究

为提高煤泥水沉降效果,实现洗水闭路循环,阐述了常用煤泥水处理方法的优缺点和应用情况,说明混凝沉淀法是目前煤泥水深度澄清的主要手段。论述了煤泥水处理药剂的作用机理和应用进展,分析了煤泥水处理的主要研究方向,说明天然有机高分子絮凝剂具有原料来源广泛、价格低廉、无毒、易生物降解等特性;微生物絮凝剂是一种高效、安全、可自然降解的新型水处理剂,开发高效安全无污染的微生物絮凝剂并将其与矿业技术结合是今后煤泥水处理技术的发展方向。最后指出在实际生产中,应根据煤质特性选择合适的煤泥水处理方法,此外还应不断优化煤泥水处理方法,研发经济、高效、绿色的煤泥水处理药剂。 To improve the effects of slime water settlement and achieve closed water circulate,describe the advantages and disadvantages, application of common slime water treatment methods. Point out that the coagulation sedimentation is the primary means of slime water depth clarification. Summarize the application and mechanism of treatment agents and the main research direction of slime water treatment. The natural organic macromolecule flocculant has properties of wide material source,low price,non-toxic,biodegradable. The microbial flocculant is efficient,safe and can be natural degraded. Developing microbial flocculant and combining it with mining technology is the direction of slime water treatment. The slime water treatment method should be chosen according to coal properties. Slime water treatment methods optimization and efficient,safe,environmentally friendly agents development is also important
