钢铁行业废水零排放运行难点及解决方案OA

In active response to policies on energy conservation,emission reduction,and cleaner production,and to promote wastewater resource reuse and achieve Zero Liquid Discharge(ZLD)goals,an increasing number of iron and steel enterprises have begun constructing ZLD facili-ties.However,numerous problems have emerged during actual operation.To address this predica-ment,this paper systematically reviews common problems encountered during the operation of pre-treatment,membrane concentration,and membrane salt separation processes within ZLD systems.It analyzes the causes of these problems and proposes targeted solutions and operational sugges-tions,providing practical guidance for the subsequent stable operation of ZLD systems.
