摘　　要：针对钢铁行业废水特点,分析了目前钢铁行业各工序及全厂主要废水污染控制措施,重点分析了二级反渗透工艺的主要流程及进出水水质,以及该工艺存在的主要问题。通过对大型钢铁集团的现场调研,以太钢采用的反渗透和蒸发结晶工艺为例分析了钢铁行业真正实现废水零排放的技术可行性。该技术可以很好解决钢铁行业浓盐水的外排问题。For the characteristics of wastewater in steel industry,the paper analyzed the current wastewater pollution control measures of mainly processes and the whole plant in steel industry,stressed the major processes,water quality and main problems of the two levels reverse osmosis. Through the site survey in large steel groups,taking TISCO’s reverse osmosis and evaporation and crystallization process as an example,the technical feasibility of zero discharge of wastewater was realized in steel industry. This technology could resolve the problem of discharging the brine.
