【摘要】：湿法脱硫废水具有含盐量高、重金属种类多等特点,目前主要采用化学沉淀法处理,但是该工艺存在药剂投加量大、污泥产生量多、以及部分指标达标困难等不足。而且该工艺出水含盐量高,排放后会产生二次污染。因此,研究开发新型、经济高效的脱硫废水处理工艺至关重要。对已有相关文献进行全面系统的分析和总结,介绍了脱硫废水的来源及组成特性,对常规湿法脱硫废水处理技术原理和利弊进行详细介绍,系统分析了流化床法、膜分离法、吸附法和电絮凝法等新兴处理技术。最后,对脱硫废水现有处理技术进行分析总结,并对脱硫废水处理技术研究和发展进行展望。
[Abstract]:The wastewater from wet desulfurization process has the characteristics of high salt content and many heavy metals. At present, chemical precipitation method is mainly used to treat the wastewater. However, there are some shortcomings in this process, such as large dosage of medicament, large amount of sludge production, and difficulty in reaching the standard of some indexes. Moreover, the effluent of this process has high salt content and secondary pollution after discharge. Therefore, it is very important to develop new, economical and efficient desulfurization wastewater treatment process. This paper makes a comprehensive and systematic analysis and summary of the related literatures, introduces the source and composition characteristics of desulfurization wastewater, introduces in detail the technical principle and advantages and disadvantages of conventional wet desulfurization wastewater treatment, and systematically analyzes the fluidized bed method and membrane separation method. New treatment technologies such as adsorption and electroflocculation. Finally, the existing treatment technology of desulphurization wastewater is analyzed and summarized, and the research and development of desulphurization wastewater treatment technology are prospected.
