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 rag/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.
