摘要: 利用自行设计的生物泥浆反应器研究了多环芳烃(PAHs)污染土壤生物修复技术.结果表明,在相同环境条件下,污染物自身的理化性质是影响生物修复的关键因素,苯环越多、分子量越大,越难以被微生物利用,故菲(PHE)比芘(PY)具有更高的污染可修复性.温度、空气流量是重要的调控因子.本实验中,生物泥浆反应器处理PAHs污染土壤选择的最佳运行工艺参数是:温度20~30℃,水土比2:1,空气流量8L·h-1·L-1,接种量50g·kg-1.该工艺参数为生物泥浆反应器技术实用化及其他相关研究工作的深入开展提供了理论依据.

Abstract: Studies on bioremediation of PAHs contaminated soil were carried out using bio slurry reactor process.Phenanthrene (PHE) and pyrene (PY) were chosen as the test pollutants.The results showed that the physical and chemical properties of the pollutants were key factor affecting the bio remedying possibility of PAHs in soil.PAHs with less benzene rings and lower molecule weight were easier to be biodegraded.So,phenanthrene had higher bio remedying possibility than pyrene.Temperature and airflow were important control factors in bio slurry reactor process. In this research,the optimized parameters were operating temperature as 20~30℃,ratio between water and soil as 2:1,airflow as 8 L·h-1·L-1,and the inoculating amount as 50 g·kg-1.
