【摘要】 概述了煤炭地下气化过程对地下水环境的影响,指出煤炭地下气化生产过程中产生的主要污染物为有机物和无机物两大类:有机物主要包括酚类、杂环类以及多环芳烃,无机污染物主要有钙、钠、钾、镁等无机阳离子以及硫酸盐、碳酸氢盐。提出气化压力控制法和严格的水文地质条件遴选是控制煤炭地下气化环境污染的主要防治措施。更多还原

【Abstract】 The effects of underground coal gasification process on groundwater environment were analyzed and summarized, and the main pollutants in this process were categorized into two components: organic pollutants including phenols, heterocyclic and polycyclic aromatic hydrocarbons,inorganic pollutants including calcium, sodium, potassium, magnesium and other inorganic cations and sulfate, bicarbonate. It is suggested that the gasification pressure control method and the strict selection of hydrogeological conditions are the main measures to control the environmental pollution of underground coal gasification process.更多还原
