Abstract:

将新型CAMBR反应器(厌氧折流板反应器(ABR)与膜生物反应器(MBR)优化组合)用于处理生活污水,研究温度对该反应器处理效能的影响。实验水力停留时间7.5h,混合液回流比设置为200%,pH值为6.5~8.5,溶解氧3mg/L左右。控制3个温度梯度:高温(32~37℃),中温(20~25℃),低温(5~10℃),每个温度运行35d。结果表明,在高温条件下,系统出水COD、NH4+-N、TN和TP平均浓度分别为25、0.5、12.5和0.7mg/L。在中温条件下,系统出水COD、NH4+-N、TN和TP浓度分别30、1.2、12.5和0.4mg/L。在低温条件下,COD和TP分别经过15d和20d调整适应,出水可恢复至35mg/L和1mg/L。由于低温(10℃以下)对硝化细菌产生强烈抑制,出水NH4+-N去除率最终稳定在35%,TN去除率为40%。低温条件下,该反应器应用于污水处理中需注意适当保温,以保证出水水质。
