【摘要】 采用驯化活性污泥来降解垃圾渗滤液较高浓度氨氮环境中的苯酚,使用好氧序批间歇反应器(SBR),在停留时间HRT为23 h,MLSS为1200-2000mg/L时,活性污泥对苯酚的去除率可达95％以上,而较高浓度氨氮条件下的苯酚的降解速率更快。更多还原

【Abstract】 Degradation behavior of phenol contained in landfill leachate with the high-strength ammonium was studied by using a SBR(sequencing batch reactor) .Results show that removal rate of phenol can reach 95% at different concentration levels of NH4+ -N at HRT of 23 h and MLSS of 1 200 - 2 000 mg/L,and further more the high-strength ammonium not only shows no inhibition to the activity of phenol-utilizing bacteria, but also could promote the degradation of phenol.更多还原
