摘要:

地下水污染问题是国家关注的重要环境问题之一,监测与评估含水层自然降解污染物能力是防治地下水污染的基本手段,也是国外地下水中修复技术研究热点课题。以华北平原某石油化工类场地为案例,通过调查场地水文地质条件、土壤及地下水污染现状,监测场地地下水中苯系物(BTEX)浓度及相关化学参数变化,运用微生物水文地球化学方法和水文地质方法,估算了该场地含水层自然降解苯系物量。这一研究成果为评估我国石油类场地地下水污染的自然修复能力提供了实证和基础数据。

Abstract:

Groundwater pollution is one of the important environmental issues concerned in China. Monitoring and assessing natural attenuation capacity of an aquifer is not only a basic means for preventing and treating groundwater pollution, but also a hot topic in groundwater remediation technology research in abroad. In this paper, authors, taking a petrochemical site in North China Plain as a case study, estimate the aquifer natural attenuation amount of BTEX per year using microbial hydrogeological and chemical method, based on investigation of hydrogeological condition and pollution status in soil and groundwater as well as monitoring of BTEX concentration and some related chemical parameters in groundwater. This research result provides an empirical and basic data for assessment of natural attenuation capacity of petroleum contaminated sites in China.

Key words: petrochemical site, groundwater pollution, BTEX, aquifer natural attenuation, assessment
