摘　　要：采用传统污水处理工艺与膜法相结合对电厂排放废水进行深度处理,实现回收利用。工程结果表明,经过传统污水处理工艺处理后的中水,经过反渗透系统,大部分悬浮物、COD及盐分被有效截留,反渗透产水悬浮物含量<10 mg/L,COD<10 mg/L,电导率<50μs/cm,可回用到生产工艺中。该工艺可实现水循环利用,减少废水的排放,创造了较为直观的社会效益和可观的经济效益。The traditional wastewater treatment technology and membrane method are used to treat the waste water discharged from power plants in depth to realize recycling.The engineering results show that after the traditional sewage treatment process,the middle water,after the reverse osmosis system,most of the suspension,COD and salt are effectively intercepted,and the content of the reverse osmosis water suspension is less than 10 mg/L,and the COD is less than 10 mg/L.The conductivity is less than 50滋s/cm and can be reused in the production process.The process can realize water recycling,reduce waste water discharge,and create more intuitive social benefits and considerable economic benefits.
