| 摘 要： | 以甲苯废气吸收液为研究对象,利用活性污泥法降解吸收液中的污染物,研究了吸收液与生活污水混合比,重点分析了反应体系降解中污染物COD、SS、SCOP和甲苯的浓度变化。实验结果表明,当吸收液与生活污水体积比为5:95,曝气量5L/min,连续曝气4h的条件下,COD、SS、SCOP和甲苯的去除率达到77.18%、94.59%、100%和89.47%,甲苯的好氧降解符合准一级动力学方程。

| Abstract: | Effects of ratio of absorbing wastewater and domestic wastewater on removal of COD,SS,SCOP and toluene from organic waste gas absorbing wastewater by activated sludge process were studied. Results indicated that 77.18% of COD, 94.59% SS,100% SCOP and 89.47% toluene were removed in 4h when ratio of absorbing wastewater and domestic wastewater were 5: 95 and aeration rate of 5L/min. Kinetics of aerobic degradation of toluene fitted quasi first order equation. |
