摘　　要：以猪皮制革废水为研究对象,在比选研究序批式生物膜(SBBR)和序批式活性污泥法(SBR)工艺处理制革废水的基础上,根据异养菌和硝化菌的微生物特性,研发形成以匀质调节—序批式生物膜(SBBR)—曝气生物滤池(BAF)为主的污水生物处理工艺.长期运行研究表明,该工艺处理效果稳定,出水水质COD≤80mgL-1,NH4+-N≤10mgL-1,SS≤30mgL-1,达到《污水综合排放标准》(GB8976-1996)一级排放标准.处理水可用于制革生产各工段冲洗水.该生物处理工艺操作方便,产泥少,无污泥回流系统,耐冲击负荷能力强,长期运行水质稳定.According to the microbial characteristics of heterotrophic bacteria and autotrophic bacteria,based on the comparison of the sequencing batch biofilm reactor （SBBR） and sequencing batch reactor （SBR）,the bioprocess for treating pig tannery wastewater by equalization tank,sequencing batch biofilm reactor and biological aerated filter （BAF） was studied.It was found that the quality of the pig tannery effluent could stably meet the first level requirements of the National Integrated Wastewater Discharge Standard （GB8976-1996）,especially,COD≤80 mg L^-1,NH4＋-N≤10 mg L^-1 and SS≤30 mg L^-1.The effluent could be reused as washing water in a tannery.Furthermore,the bioprocess had the following characteristics such as easy operation,less sludge,no return sludge system,great ability of shock load resistance and so on.Fig 9,Tab 3,Ref 15
