摘　　要：为解决序批式活性污泥法(SBR)对含盐生活污水处理效率低的问题,考察了油菜秸秆生物炭(RSB_(650))投加对污染物去除效率和污泥性能的影响,探讨了应用于强化含盐生活污水处理效果的可行性和机制。结果表明,投加1.5~2.0 g/L RSB_(650)至受中低盐度(0.5%~1.0%)冲击的SBR系统,经11 d~50 d运行后COD、NH_(4)^(+)-N、TP去除率可恢复至90%以上,TN去除率可恢复至80%以上;而投加2.0 g/L RSB_(650)至受较高盐度(1.5%)冲击的SBR系统,上述污染物去除率仅能恢复至50%~80%左右。RSB_(650)优良的结构特性为SBR系统抵御盐度冲击提供了有利条件,用于强化中低含盐度生活污水处理效果具有良好的可行性。Aiming to tackle the inefficiency of the sequencing batch activated sludge(SBR)method in salt-laden domestic sewage treatment,the effects of rape straw biochar(RSB_(650))dosing on pollutant removal efficiency and sludge performance were investigated,and the applicability and mechanics of its use for enhanced salt-laden domestic sewage treatment effects were probed.The outcomes revealed that the COD,NH_(4)^(+)-Nand TP removal rates could be recovered to more than 90%,and the TN removal rate could be recovered to more than 80% after 11~50 days of operation by adding 1.5~2.0 g/L RSB_(650) to the SBR system subjected to the impact of low to medium salinity(0.5%~1.0%),while the removal rates of the above pollutants could only be recovered to 50%~80% in the SBR system impacted by high salinity(1.5%)with the dosage of 2.0 g/L RSB_(650).The excellent structural characteristics of RSB_(650) provide favourable conditions for the SBR system to withstand the salinity impact,and it is feasible to use it to enhance the treatment effect of domestic sewage with low and medium salinity.
