The treatment of wastewater containing high concentration of salt by reverse osmosis and evaporation method are studied
after the wastewater be treated
major pollutants like CODcr and BOD5 of the condensate can be removal more than 95% and 98.5%. And the wastewater can be achieved the highest lever in table 4 of GB 8978—1996 "Integrated Wastewater Discharge Standard"
that can reduce the impact on the receiving water
