摘　　要：全膜法(IMT)处理工艺,用两级反渗透(RO)+电去离子(EDI)处理工艺,代替传统的RO+混床处理工艺,在初始投资相近的情况下,由于系统无酸碱消耗,无废水排放,无需再生用水,运行费用显著降低,同时系统占地面积大大下降。IMT水处理系统出水水质优良,运行稳定,出水电导率小于0.2μS.cm-1,含硅量小于20μg.L-1,符合电厂锅炉补给水水质要求,综合性能优于RO+混床处理工艺。IMT watertreatment technology,which instead of the RO＋osmosis-mixed bed treatment process,with two step RO＋EDI processing,had a lower operating costs than the traditional watertreatment technology with the similar initial investment,since no acid-base system consumption,no waste water discharge,no regeneration of water,and small footprint.IMT water treatment system was stable,the effluent water conductivity was less than 0.2 μS·cm-1,silicon content was less than 20 μg ·L-1,which was consistent with requirements of the power plant boiler make-up water quality.The overall performance of the IMT water treatment technology was superior than the RO＋osmosis-mixed bed treatment process.
