摘要
针对燃煤电厂进行脱硫废水零排放处理时成本较高问题,提出对烟气余热浓缩后的废水进行沉淀、酸化、纯化、提纯等工艺,可以提纯出纯度及经济价值较高的氢氧化镁,降低燃煤电厂的废水处理成本。
In view of the high cost of zero discharge treatment of desulfurization waste water in coal-fired power plants,the process of precipitation,acidification,purification and purification of waste water after flue gas waste heat concentration is proposed,which can purify magnesium hydroxide with high purity and economic value and can save the cost of waste water treatment in coal-fired power plants.
