摘要
随着国家环保政策的持续收紧,燃煤电厂脱硫废水排放问题日渐凸显。通过对脱硫废水的特点分析,明确了现有处理方法与国家政策之间的矛盾。介绍了国际国内的主要脱硫废水零排放工艺及应用案例,目前各项技术均存在一定的优缺点,开发稳定性更高、投资运行成本更低的脱硫废水零排放技术是未来的发展趋势。
With the continuous tightening of national environmental protection policy,the problem of desulfurization wastewater discharge from coal-fired power plants is becoming increasingly prominent.Based on the analysis of the characteristics of desulfurization wastewater,the contradiction between the existing treatment methods and national policies is clarified.The main desulfurization wastewater zero discharge processes and application cases at home and abroad are introduced.At present,there are some advantages and disadvantages in various technologies.The development of desulfurization wastewater zero discharge technology with higher stability and lower investment and operation cost is the future development trend.
