废水处理剂ABR Hydrocarbon对石油污染土壤生物修复的研究

摘要

The application conditions of wastewater treatment agent ABR Hydrocarbon and the microbial remediation of petroleum contaminated soil were studied. The results showed that the optimal fermentation temperature of wastewater treatment agent ABR Hydrocarbon was 40 ℃, and the optimal fermentation pH was 7. 0 , surfactants produced in the fermentation liquid, there was a good correlation between the activity of dehydrogenase activity and the degradation rate of petroleum hydrocarbons in soil. After continuous cultivation for 32 days, petroleum hydrocarbon degradation rate reached 33. 4%, soil microbial dehydrogenase activity was 83. 0 μg/( g · h ) . The experiments showed that the wastewater treatment agent ABR Hydrocarbon had good petroleum hydrocarbon degradation ability.%对废水处理剂ABR Hydrocarbon的应用条件及其对石油污染土壤的微生物修复进行了研究。结果表明：废水处理剂ABR Hydrocarbon的最佳发酵温度为40益、最佳发酵pH为7.0,发酵液中有表面活性物质产生,土壤中微生物的脱氢酶活性与石油烃降解率之间存在较好的相关性。连续培养32天,石油烃的降解率达到了33.4%,土壤微生物脱氢酶活性为83.0μg/( g·h)。试验表明废水处理剂ABR Hydrocarbon具有较好的石油烃降解能力。
