STUDY OF BRACKISH WATER TREATMENT TECHNOLOGY IN HIGH SALT MINE AREA

According to high-turbility,high salt and high hardness character of brackish water in Xinjiang Lop Nur potassium salt mine;the paper studied the following technology:pipeline coagulation plus the multi -media filtration plus fine filtration plus reverse osmosis for the brackish water treatment.The treatment result shows that the technology has good treatment effect to suspended solids,turbidity and TDS of brackish water.In the effluent,the TDS is decreased from 8000mg/L to 30 mg/L,the increment of SiO2 is less than 20μg/L.The effluent quality completely meets the requirement of the make-up water in power generating units.The research provides the technology reference for high salt poor-quality water use of severe water shortage mine.
