中水处理工艺及其工业应用

Reclaimed Water Reuse Process and its Industrial Application

针对煤化工用水情况,介绍并分析了中水处理装置的工艺原理、流程以及在运行过程中所产生的经济和环境效益。来自污水处理厂的中水达到国家A标后进入中水处理装置,经生物流化床+凝聚+沉淀+过滤+脱盐工艺处理后,出水完全能够满足化工企业生产用脱盐循环水的要求。

In connection with water use situation of coal chemical industry, introduction and analysis are made of the process principle and flow of reclaimed water treatment plant and the economic and environmental benefits generated in operation. After coming up to level A of the national standard, the reclaimed water from wastewater treatment plant enters reclaimed water treatment plant, through process treatments, including biological fluidized bed, coagulation, precipitation, filtration and desalination, the water can fully satisfy the requirement of circulating desalinated water used in production of chemical enterprises.
