石油污染盐碱土壤生物修复模式研究
Study on Bioremediation Mode of Saline Soil Contaminated by Petroleum
摘要
Abstract
[Objective]To find a suitable bioremediation model for petroleum contaminated saline soil.[Method]Based on the oil-degrading bacteria flora saved by experiment previously and screened freshly,the solid fertilizer was prepared.The effect of C∶N∶P and the quantity of solid fertilizer on oil-degradation rate and amount of microbe were studied,and the impact of quantity of solid fertilizer applied,kinds of plant,tillage on remediation of contaminated soil in the field were studied by experiment.[Result]Degradation characteristics of fertilizer determined the degradation efficiency of petroleum pollutants,remediation invalid fertilizer will reduce oil pollutants in both indoor and outdoor test.In the soil C∶N∶P under appropriate conditions,the fresh fertilizer application amount increased,which can effectively improve the degradation of oil pollutants.Enough fertilizer can play a role the degradation in the short term (10-20 d).In the field remediation model,the effect of tillage on the remediation of contaminated saline soil was limited.The indigenous dominant plant Suaeda glauca was more suitable for phytoremediation than Medicago sativa.[Conclusion]Under field conditions,the appropriate bioremediation mode for saline soil contaminated by oil was Suaeda glauca + 10% fresh bacterial fertilizer +no tillage + nutrition (C∶N∶P=100∶5∶3).关键词
