【摘要】：选取石河子市典型燃煤电厂,对其燃煤烟气重金属排放浓度及飞灰、底渣、脱硫石膏重金属的富集进行定量分析。结果表明,烟气中各重金属排放浓度从高到低依次为Zn、Ni、Cr、Pb、Cu、Hg、Co、Cd、As。各重金属元素在飞灰中的富集程度较高,除Hg、Cd、Ni外,其他重金属元素在飞灰的富集因均值均大于5。其中,As在飞灰的富集因子均值为5.76。研究结果可为石河子重金属污染控制提供基础数据。
[Abstract]:A typical coal-fired power plant in Shihezi City was selected to quantitatively analyze the concentration of heavy metals in flue gas and the enrichment of heavy metals in fly ash, bottom slag and desulphurized gypsum. The results show that the emission concentrations of heavy metals in flue gas from high to low are ZnONiNiCrPbPbPbCuHgCuHG / CD ~ (2 +) ~ (2 +) As in the order of high and low levels of heavy metal emission. The enrichment degree of each heavy metal element in fly ash is higher than that in fly ash. The average enrichment factor of as in fly ash is 5.76. The results can provide basic data for heavy metal pollution control in Shihezi.
