摘要

本文研究了燃煤火电厂飞灰进入非线型灰池后对地下水的污染。选择Tendubhata作为马尔瓦热电厂灰池周围的研究场地。采用复合抽样法随机抽取地下水样本。在煤、粉煤灰和地下水样品中检测到10种重金属(Ca、Cu、Cd、Cl、Zn、Pb、Ni、Cr、Mn和Fe)。采用能量色散x射线荧光法评价煤和粉煤灰中的重金属浓度,采用原子吸收光谱法评价地下水中的重金属浓度。监测结果显示,该地区地下水重金属超标。

Heavy Metal Concentration in underground water due to Fly Ash at Janjgir Champa region in Chhattisgarh
The present study focused on the groundwater contamination due to fly ash disposal of coal-fired thermal power plant into a non-liner ash pond. Tendubhata were selected as study site around ash pond of Marwa thermal power plant. Groundwater samples were collected on random basis using composite sampling method. Ten heavy metals (Ca, Cu, Cd, Cl, Zn, Pb, Ni, Cr, Mn, and Fe) were detected in coal, fly ash, and groundwater samples. Heavy metal concentration in coal and fly ash was assessed by Energy Dispersive X-ray Fluorescence, while AAS was used for groundwater assessment. The observed results revealed the exceeding value of heavy metals prescribed by WHO for groundwater.
