摘要
由于煤矿资源的过度开采,使得矿区土壤重金属污染问题加剧。为了有效解决这一问题,提出生态敏感性下矿区土壤重金属污染治理技术。该方法通过获取矿区边坡数据,并根据获取结果将矿区划分成5个生态敏感因子,结合生态敏感性综合指数,评价矿区生态敏感的可视化分布;通过对矿区土壤的采样及重金属形态测定,取得不同采样点的矿区土壤重金属污染指数。依据获取结果,采用沸石-生物炭配施,对矿区土壤重金属实施治理修复。根据最终修复评价可知,复合改良剂对污染土壤的治理及修复具有优越性。
Due to the excessive mining of coal resources,the problem of heavy metal pollution in the soil of the mining area is aggravated.In order to effectively solve this problem,the research method of heavy metal pollution control technology in mining soil under ecological sensitivity was proposed.This method obtains the slope data of the mining area,divides the mining area into five ecological sensitive factors according to the obtained results,and evaluates the visual distribution of the ecological sensitivity of the mining area combining with the comprehensive index of ecological sensitivity.Through the sampling and heavy metal speciation determination of the mining area soil,the heavy metal pollution index of the mining area soil at different sampling points was obtained.According to the obtained results,the heavy metals in the soil of the mining area were treated and remedied by the combination of zeolite-biochar.According to the final remediation evaluation,the composite modifier has advantages in the treatment and remediation of contaminated soil.
