摘要
用生物通风技术来修复土壤中有害的有机污染物 ,试验研究结果显示 :通风流量为 2 0mL/min时 ,挥发去除的甲苯与生物降解去除的比例约为 1 5∶1。在土柱通风操作的 2 2 6h期间 ,共有 96 6 8%的甲苯被去除 ,同时产生了 12 8 13mg的CO2 ,生物降解所去除的甲苯约为初始加入甲苯的 4 2 %~ 4 9%。
Bioventing method was used to remedy the organic contaminants in soil. Experimental data show that the ratio of removing toluene by volitilization to that due to biodegradation by bioventing was about 1.5∶1.During the course of 226?hr of the operation, about 96.68% of the initial toluene was removed, and 128.13?mg CO 2 was produced.The toluene removed by biodegradation was about 42%~49% of the initial mass.
