混凝技术在焦化废水深度处理中的应用

摘要

The research status of several kinds of conventional coagulants and novel coagulation methods applied in coking wastewater advanced treatment were elaborated. The existing problems of the currently used coagulation methods were summarized, besides, the future application and development trend of the coagulation technology and its combination process were also analyzed. It was pointed out that, the mechanism and industrial application of magnetic coagulation, electro coagulation, coagulation-oxidation, and coagulation-membrane tech-nology, should be thoroughly researched, more than that, a further study on efficient organic-inorganic macro-molecule coagulant for coking wastewater treatment was also required.%综述了焦化废水深度处理中几种常规混凝剂及一些新型混凝法的研究现状,总结了当前混凝技术用于焦化废水深度处理中存在的问题,分析了混凝技术及其组合工艺未来的应用发展趋势,指出应深入创新研究磁混凝、电混凝、混凝-氧化、混凝-膜技术的机理及工业化应用,以及进一步研究针对焦化废水的高效的有机-无机高分子混凝剂.
