热电厂除盐水装置的节水降耗技术应用
|
摘要
在离子交换废水再利用工艺研究的基础上,通过在热电厂除盐水装置增建酸碱废水回收和再利用系统,对酸碱废水进行回收和重复利用,每年减少废水外排量为20×10~4m~3,其他经济效益达200余万元。该工艺的工业化应用经验,可供同行借鉴。
Based on the research of ion exchange wastewater reuse process,the acid-alkali wastewater recycling and reuse system was added to the desalination unit of the thermal power plant to recycle and reuse the acid and alkali wastewater. The annual effluent discharge was reduced by 20 × 10~4 m~3,and other economic benefits reached more than 2 million yuan. The industrial application experience of this process could be used for reference.
