摘要：

天津市王朝包装印刷有限公司废水处理工程采用混凝沉淀—生物接触氧化组合工艺处理包装印刷废水,取得了很好的处理效果,其对废水中COD、BOD₅、NH₃^-N、色度等污染指标的去除率均在90%以上。从工程验收完毕后两个多月的运行情况来看,系统运行稳定,出水优于相关排放标准。

Abstract:

The coagulating sedimentation-biocatalytic oxidation combined technology has been introduced to the baling and printing wastewater treatment project, from which perfect effects are obtained. The removal rates of the COD,BOD₅,NH₃ - N,chroma and so on in the wastewater are all above 90%. Based on the operational aspect after finishing the checking and acceptance of this engineering for two months,the system runs steadily and the effluent is better than the relevant discharge standard.

Key words: baling and printing wastewater, coagulating sedimentation, hydrolyzing acidification, bio-aeratic fluidized, bed
