摘　　要：随着工业化的发展,化工废水对环境的污染也变得越来越显著.采用复合厌氧反应器(HAF)、微氧生物反应器(MABR)、流离生物反应床(FSBBR)等组合工艺对某化工企业生产和清洗废水进行处理,最终出水的COD Cr稳定在100 mg/L左右,氨氮稳定在15 mg/L以下,出水水质符合污水综合排放一级标准(GB8978-1996).该工艺在运行期间抗冲击负荷能力强,出水水质稳定,为后期处理含有难降解污染物工业废水的实际工程处理奠定基础.With the development of industrialization,the pollution of chemical wastewater to the environment has become more and more significant.The combined processes of hybrid anaerobic filter(HAF),micro-aerobic biological reactor(MABR)and flow separate bed biological reactor(FSBBR)are used to treat the production and cleaning wastewater of a chemical enterprise.The final CODCr of the effluent is stabilized at about 100mg/L,ammonia nitrogen is stabilized below 15mg/L.The effluent quality meets the first-level standard of comprehensive sewage discharge standard(GB8978-1996).The process has strong impact load resistance during operation and stable effluent quality,which lays the foundation for the actual engineering treatment of industrial wastewater containing refractory pollutants in the later stage.
