摘要
以累托石层孔材料为吸附剂、以FO2为添加剂对含铬电镀废水进行处理 ,并对其吸附性能做了初步的探讨。实验结果表明 ,在不改变原水 pH值的条件下 ,吸附剂用量为 2 .5g/L ,还原剂用量为 0 .5g/L ,处理后水中残留铬浓度为 0 .2mg/L ,远低于国标GB8978- 1996一级排放标准 ;累托石吸附铬的反应符合Freundlich吸附经验式 :lgQ =- 1.910 2 + 0 .35 4 5lgC。
In this paper, the Chromium-containing wastewater treatment with rectorites as adsorption reagent and with FO2 as redacting reagent has been studied. The sorption behavior of rectorites for chromium (Ⅵ) also were investigated. The result of the experiment shows that under the condition without changing its pH, the amount of the rectorites in 2.5g/L, FO2 0.5 g/L, it can make the wastewater reach the standard and drain off. It's more economical. The sorption behavior of rectories for chromium (Ⅵ) obeys the Freundlich, lgQ= -1.9102 + 0.3545 lgC.
