摘要
“十三五计划”提出提高各工厂的废水排放标准,作为高排放水量的火电厂,其废水近零排放是必然趋势。火电厂烟气脱硫废水因成分复杂、高浊度、高硬度、回用困难,成为制约火电厂废水“近零排放”实现的关键因素之一。本文针对火电厂中脱硫废水处理问题,从预处理和深度处理两方面简述了国内外实现脱硫废水近零排放处理装置的研究现状,为火电厂脱硫废水的近零排放提供参考。
With the proposal of “the 13th Five-Year Plan” to improve the wastewater discharge standards of various factories, as a thermal power plant with high discharge water, the near-zero discharge of wastewater becomes an inevitable trend. Because of its complex composition, high turbidity, high hardness and difficulty in reuse, flue gas desulfurization wastewater from thermal power plant has become one of the key factors restricting the realization of near-zero discharge of thermal power plant wastewater. Aiming at the problem of desulfurization wastewater treatment in thermal power plant, the research status of near-zero discharge treatment device for desulfurization wastewater at home and abroad is briefly described from two aspects of pretreatment and advanced treatment, which provides a reference for near-zero discharge of desulfurization wastewater in thermal power plant.
