摘要
采用优化土著微生物菌群的生物技术,开展了华北濮阳地区石油污染地下水的修复实验。选择优化出的菌群包括假单胞菌属、微球菌属、放线菌属、真菌类的青霉属、曲霉属;实验过程中,分别在石油含量为182.0mg/L、862.5mg/L、1695.0mg/L污染水中加入了1.5%的优化菌群制剂。经过28d、37d、37d的修复实验,三种浓度中石油污染物的最大累计去除率分别为53.46%(28d)、70.87%(37d)和58.19%(37d),和对照5%的净化率相比,加入优化菌群制剂显著提高了石油污染物的去除率;温度是影响修复效果的因素之一,30℃是该菌群的最佳生长温度,对油污地下水的修复效果最明显,浓度是影响石油污染物浓度的另一重要因素。
Using optimized indigenous microbial flora biotechnology, we had conducted repair experimental research on oil-contaminated groundwater in Puyang area of North China. The selected optimized flora include pseudomonas, micrococcus, actinomyces, fungi such as penicillium and aspergillus; in experiment process, add 1.5%＇s optimized flora preparation into the polluted waters with oil content of 182.0mg / l, 862.5mg / l and 1695.0mg / l. After 28 days,37days and 37 days remediation experiments, the maximum cumulative removal rates of oil pollutants in the three concentrations are 53.46% （28d）, 70.87% （37d） and 58.19% （37d）. The temperature is one of the remediation affecting factors and 30℃ is the best flora growth temperature, with the most significant remediation effect on oil-contaminated groundwater; concentration is another important factor influencing oil pollutants; in sterile contrast experiment, the removal rate of oil pollutants is within 5%, indicating slow groundwater oil degradation in natural conditions.
