双膜法在安钢污水深度处理中的应用

摘要

Double membrane method was used in advanced treatment of industrial wastewater to reach national secondary discharged water standard. Through the process of pretreatment, ultrafiltration, reverse osmosis and mixed bed, qualified desalinated water was produced with water conductivity at exit smaller than 10 μS/cm and SiO2 content lower than 0.1 mg/L. The process is not only environment friendly but also energy saving.%工业废水水处理达到国家二级排放标准的外排水，采用双膜法进行深度处理，经过预处理、超滤、反渗透、混床产出合格的脱盐水，出水水质电导率小于10μS/cm，二氧化硅含量小于0.1 mg/L，该工艺环保又节能。
