电厂锅炉清洗废水治理工艺

Technique of Power Plant Boiler Cleansing Water Treatment

电厂锅炉清洗废水中,含有高浓度的柠檬酸和丙酮肟等有机污染物。经试验,采取原水作适当稀释后,进行好氧曝气——活性炭生物膜法二级处理,COD_(Cr)总去除率可达88％—90％;BOD_5去除率为90％。经两级处理后的出水,COD_(Cr)<100mg/l,BOD_5<50mg/l,可达到较好的处理效果。

Power Plant boiler cleansing wastewater contains high concentration of citric accid and acetone oxime organic pollutants. By adopting dilution of original water and then treated with aerobic aeration activated carbon biomembrane method, secondary treatment, total removal rate of CODcr was up to 88%—90%, and BOD_5 90%. CODcr abd BOD_5 in the effluent were less than 100mg/l and 50mg/l respectively after secondary treatment.
