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 μs/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.
