2.2 开发末端脱硫废水的蒸发结晶处理系统

确保整个系统的安全运行,石膏—石灰石湿法的脱硫系统要定时排一些废水才能正常运行,这个称为脱硫废水。脱硫废水是全系统的产生的废水,pH是5~6,但是盐的含量是25000~55000mg/L,废水中有Cl-、过饱和亚硫酸盐、悬浮物、重金属与硫酸盐等,此废水容易结垢,有很强的腐蚀性。运用常用的工艺处理以后,采用常规工艺处理后,排放的污水达标有关标准,可是这个废水的硬度很高、Cl-没有减少,有很强的腐蚀性,不能直接重复利用,要经过外排或者是加入粉煤灰来调节湿度。国内外还没有先例将脱硫的废水输送到前端的设备继续使用。要去除废水中氯离子浓度和硬度的浓度,以免设备结垢或者受到腐蚀,只有解决这个问题,脱硫的废水才能重复使用。河源电厂开发了 “多效蒸发结晶+二级预处理”脱硫废水进行处理工艺的先例,实现了盐分和污泥的完全分离,污水经过上述工业处理后水质跟蒸馏水无异,通过管道回水至前端的处理工艺,整个过程无废水排放,达到工业废水零排放
