Abstract:

以北京某焦化厂污染土壤为研究对象,按照5:1的比例添加锯末后加入5%的草炭进行好氧堆肥,通过对污染土壤堆肥处理过程中16种PAHs的降解率、CAT值、SOM值、土壤毒性、pH和TN值的变化规律进行比较,研究添加草炭好氧堆肥对实际有机污染土壤中PAHs的降解效果。研究结果表明,(1)添加草炭好氧堆肥能有效降解有机污染土壤中PAHs,堆肥49d后,EPA优控的16种PAHs总值从1085.42mg/kg降低到71.10mg/kg,总降解率为93.27%。(2)焦化厂土壤中PAHs浓度较高的分别为荧蒽、菲、芴、苯并(a)蒽、芘、蒽和苯并(k)荧蒽,它们的和占Σ16PAHs总量的73.56%,其中荧蒽的含量最高,浓度为186.913mg/kg。这7种PAHs的经过49d添加草炭堆肥后降解率分别为95.67%、93.52%、92.22%、93.12%、93.01%、95.19%和96.24%。(3)通过有机质值和Σ16PAHs总量作图发现,有机质值和Σ16PAHs总量有一定的相关性,这表明在堆肥过程中,微生物在PAHs降解过程中起到很大的作用。
