摘要
介绍了电厂再生高盐废水产生阶段和一种再生废水分盐收集方案。通过对某电厂精处理混床再生废水水量,水质变化规律测试、分析,明确了高盐废水主要产生于进酸/进碱、置换、快速漂洗3个阶段;基于高、低盐废水划分的分界点,提出了与再生时间程序联锁控制的分盐收集方案,实现再生废水的分质收集、分质回用,每个再生周期仅产生12.2%的高盐废水,回收的低盐水电导率小于0.2mS/cm,优于原水水质。
This paper introduces the stage of generating high-salt wastewater and a salt-separating collection scheme for the regeneration wastewater in a power plant.Through the test and analysis of the water flow and quality change of a mixed-bed,it is clarified that high-salt wastewater is mainly produced in three stages:acid/alkali,replacement,and rapid rinsing;according to the boundary between high and low salt wastewater,based on the demarcation point of the division of high and low salt wastewater,a salt-separating collection scheme interlocked with regeneration time program is proposed.This scheme can realize the qualitative collection and reuse of regenerating wastewater,and only 12.2%of high-salt wastewater is generated in each regeneration cycle.The recovered low-salt water conductivity is less than 0.2mS/cm,which is better than the raw water quality.
