摘    要:以地下水NO3^-污染为例,利用优选的菌群刺剂和少量营养碳源,在河北平原进行了NO3^-污染地下水的原位微生态修复试验.试验结果显示,地下水NO3^-含量在58~72.66mg/L时,经4.5~10天的修复试验,地下水中NO3^-含量降低至7.38~0.85mg/L,去除率达到86.5%~98.8%,去除效果较好,持续时间长.该方法为修复治理大面积地下水NO3^--N污染提供了可行的技术支撑.

关 键 词:地下水  硝态氮污染  微生态  原位修复  河北平原

Abstract:Take NO3^--N pollution of groundwater for example, the authors used a selected microbial pool agent and a little nutrient carbon to perform an experiment for in situ microecological remediation of NO3^--N-contaminated groundwater in the Hebei plain. The results indicate that the NO3^- concentration in groundwater decreases from 58-72.66 mg/L to 7.38-0.85 mg/L through 4.5-10 days of remediation experiment with the removal rate reaching 86.5-98.8%. The removal effect is good and lasted long. The technique provides a feasible technical support for the remediation and control of extensive NO3^--N pollution of groundwater.
Keywords:groundwater  nitrate contamination  microecology  in-situ remediation  Hebei plain
