物化-生化法组合工艺降解酞菁蓝生产废水

Treatment of Wastewater from Phthalo Cyanine Blue Production with Physical and Biological Process

酞菁蓝生产废水中含有COD1 657 mg/L,BOD1 048 mg/L,NH3-N895 mg/L,Cu2+25.6 mg/L,采用物化、生化组合处理工艺,出水各项污染物指标均达到《污水综合排放标准》的一级指标。COD去除率90.7%;BOD去除率88.5%;NH3-N去除率99.1%;Cu2+去除率99.2%。本方法操作简单,工艺流程合理,处理效果好,可操作性强,环境友好。

The wastewater discharged from the production of phthalo cyanine blue pigment contains COD （1 657 mg/L）, BOD （1 048 mg/L）, NH3-N （895 mg/L） and Cu^2＋ （25.6 mg/L）. When a combined process of physical-chemical and biochemical treatment was used, the outlet of the treatment is measured up the first-class of the let standard complex. This method has some merits, including convenient operation, optimizing process-flow, ideal treatment effect, strong operation and friendly environment.
