厌氧水解—接触氧化—混凝气浮工艺处理化工废水

摘要

采用厌氧水解—接触氧化—混凝气浮工艺处理化工废水,运行结果表明,当进水COD、氨氮、SS、TP、苯胺、色度分别为875 mg/L、22.5 mg/L、400 mg/L、10.5 mg/L、12 mg/L、200度时,出水分别为87.4 mg/L、7.1 mg/L、7.8mg/L、0.4 mg/L、1.3 mg/L、17.4度,出水可稳定达到GB 8978-1996《污水综合排放标准》的二级排放标准要求,处理效果稳定.%The process of anaerobic hydrolysis-contact oxidation-coagulation flotation has been used for treating chemical wastewater.The operation results show that when the average mass concentrations of influent COD,NH3-N,SS,TP,aniline,and chroma are 875 mg/L,22.5 mg/L,400 mg/L,10.5 mg/L,12 mg/L,200 degree respectively,the effluent would correspondingly be 87.4 mg/L,7.1 mg/L,7.8 mg/L,0.4 mg/L,1.3 mg/L,17.4 degree,meeting the second class of Integrated Wastewater Discharge Standard(GB 8978-1996),and the treatment efficacy is stable.
