冷轧废水回用处理的研究进展

Research progress of cold rolling wastewater reuse treatment

随着国家对钢铁企业节能减排的日益重视,废水资源化利用和“零排放”逐渐成为钢铁企业发展的目标。冷轧产品作为钢铁企业的主要产品之一,使得冷废水逐渐成为钢铁行业废水关注的焦点,其污染物种类较多,成分复杂,给废水回用处理带来了较大的难度。分析了冷轧废水回用处理的现状,并对回用技术在工程应用中的发展趋势进行了分析。

As the country pays more and more attention to energy saving and emission reduction of steel enterprises,waste water resource utilization and"zero discharge"gradually become the goal of steel enterprises.As one of the main products of iron and steel enterprises,cold-rolling products have gradually become the focus of wastewater in iron and steel industry.The cold-rolled wastewater has more types of pollutants and complex components,which makes waste-water reuse treatment more difficult.The current situation of cold rolling wastewater reuse treatment is analyzed,and the development trend of reuse technology in engineering application is analyzed.
