以淹没式微滤或超滤和新型纳滤膜 (比普通纳滤膜能更为有效地去除有机污染物和较少地去除硬度和矿物质 )代表的饮用水深度净化新技术 ,具有去除有机污染效率高 ,有机污染的去除率高达90 %以上 ,在线颗粒计数 (d>2μm )小于2个/mL。而且出水能有效地去除三致物质前质、病毒和病原原生动物。运行能耗低 ,费用低。淹没式超滤的能耗仅为0.2kWh/m3 ,同时原水中存在的对人体健康有益的矿物质和微量元素仍保留在产水中。
New technologies for deep purification of drinking water represented by submerged microfiltration or ultrafiltration and new nanofiltration membranes (more effective in removing organic contaminants and less removing hardness and minerals than ordinary nanofiltration membranes) have the ability to remove organic contamination. The efficiency is high, the removal rate of organic pollution is up to 90%, and the online particle count (d>2μm) is less than 2/mL. Moreover, the effluent can effectively remove the three substance precursors, viruses and pathogenic protozoa. Low energy consumption and low cost. The energy consumption of submerged ultrafiltration is only 0.2 kWh/m3. At the same time, the minerals and trace elements that are beneficial to human health that exist in raw water still remain in the production water.
