粘土层孔材料处理含铬废水的研究

Study on the treatment of chromium-containing wastewater with rectories

研究了以粘土层孔材料作为吸附剂 ,以F0 2为添加剂对含铬电镀废水的处理 ,并对其吸附性能作了初步探讨。试验表明在不改变原水 pH值的条件下 ,吸附剂用量为 2 5 g/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 ;试验结果还表明

The treatment of chromium containing wastewater with rectories as adsorption agent and F02 as reacting agent is studied. The adsorption behavior of rectories is investigated. The results show that under the conditions of without changing the pH value of wastewater, the amount of rectories 2.5g/L, F02 0.5g/L, the concentration of chromium(Ⅵ) can reach 0.2mg/L, which lower than that in the standard of GB8978-1996. The adsorption behavior of rectories for chromium(Ⅵ) obeys the Freundlish experience relation.
