摘要
以活性污泥为材料吸附处理垃圾渗滤液中的Cr(Ⅵ),研究溶液pH值、活性污泥投加量、吸附时间、温度和转速等因素对吸附效果的影响。结果表明,选取pH值为7、活性污泥投加量为15g、吸附平衡时间为20 min、吸附温度为25℃、转速为100 r·min-1具有最佳的吸附效果,在此条件下,Cr(Ⅵ)的吸附率可达65%。
The adsorbing Cr （VI） of the activated sludge with different pH, increment of the activated sludge, adsorption equilibrium time, temperature and rotational speed were studied. The experimental results showed that the optimum conditions were studied pH 7.0, the increment of the activated sludge 15 g, the adsorption time 20 min,the adsorbent temperature 25℃, the rotational speed 160 r·min^-1. Activated sludge capacities of adsorbing Cr （Ⅵ） separately reached 65% under the optimum adsorption condition.
