摘要
采用絮凝沉淀+接触氧化+人工湿地工艺处理印染废水中COD研究。结果表明,斜板沉淀池出水COD平均值为1322mg/L,此间COD去除率为38·6%;二沉池出水COD平均值为71mg/L,此段COD去除率达94·6%;人工湿地出水COD平均值为37mg/L,人工湿地COD去除率为48·0%。处理设施COD总去除率98·3%。
COD removal from dyeing wastewater with flocculation ＋ contact oxidation ＋ artificial wetland process was studied. The results showed that the effluent concentrations of COD from flocculation, contact oxidation and artificial wetland process were 1322 mg/L, 71 mg/L, and 37 mg/L, the removal rates of COD were 38.6% , 94.6% and 48.0% respectively. Total removal rate of the disposal system was 98.3%.
