Design of Water Purification Plant of Micro-polluted Source Water in Shendong Mine Area

According to the characteristics of micro-polluted surface water source in Shendong mine area,combined with technology research and engineering practice of micro-polluted source water treatment in recent years,the integrated treatment technologies including potassium permanganate double salt / powdered activated carbon pretreatment,enhanced conventional treatment and ozone / activated carbon advanced treatment could effectively remove organic matters from the polluted water body. The finished water quality was superior to the Standards for Drinking Water Quality( GB 5749- 2006),with turbidity 1 NTU,color 10 and COD Mn 1 mg / L. The operation practice showed that the process had the characteristics of stable operation effect,high degree of automation,and low running cost. Meanwhile,the process selection,process flow,design parameters of main structures were introduced for reference.
