循环冷却排污水深度处理回用研究进展

摘要

循环冷却排污水的回用处理方法有超滤、反渗透、膜蒸馏、电吸附等.综述分析了这几种方法的原理、优缺点和应用现状,并列举了国内外相关的试验研究进展和工程应用实例.对循环冷却排污水进行深度处理回用,既能节约水资源满足生态效益,又能减少用水成本实现经济效益.%RO,membrane distillation and electrosorption are commonly used for desalination of cooling tower blowdown. The principle,advantages and disadvantages and application of these methods are intro-duced and analysed. In addition,experimental research progress as well as some application examples both at home and abroad are reviewed. It is economical and environmentally friendly to purify and reuse cooling tower blowdown.
