脱硫废水中不同类型污染物零排放 技术的研究与应用.

This article summarizes the source and water quality characteristics of desulfurization wastewater, and introduces the main treatment technologies for heavy metals, COD, chloride ions and other pollutants in desulfurization wastewater at this stage・ The basic reviews and analyzsis the principles, applicability and problems of different processing technologies in actual operation, lists cases of zero discharge of desulfurization wastewater that are already in operation. In view of the shortcomings of different technologies, the future direction of zero discharge treatment technology for desulfurization wastewater of coal-fired power plants is expected to be expanded, that is - the implementation of pre treatment integration to reduce operating costs; the development of new membrane materials to improve the efficiency of the advanced treatment stage of desulfurization wastewater. In order to provide idea for the selection and design of desulfurization wastewater removal technology for coal-fired power plants. [ABSTRACT FROM AUTHOR]
