摘要: 针对传统技术制备污泥活性炭的比表面积不高、吸附值低等不足，通过在污泥中添加核桃壳以改善污泥原料缺陷，研究了活化剂种类、核桃壳加量、活化温度、活化时间、活化剂浓度及浸渍比等影响活性炭吸附能力的制备条件。在优化后的条件下制备出了高吸附性能的生物质污泥复合活性炭。结果表明：选择氯化锌作为活化剂，核桃壳加量20%、活化温度500℃、活化时间60 min、活化剂浓度2.5 mol·L-1、浸渍比1：2.5为最优化制备条件。制备出的生物质污泥复合活性炭碘吸附值为574.11 mg·g-1，产率为43.93%。

Abstract: According to the deficiencies of traditional technology of sludge activated carbon preparation such as low specific surface area and low adsorption, the research focus on improving the defects of raw sludge material by adding walnut shell in sludge, studying the experiment condition such as the species of activator, the mass fraction of walnut shell, activation temperature, activation time, activator concentration and dipping ratio, etc. It can provide high adsorption performance biological sludge activated carbon under the optimum experimental conditions. The optimization condition is choosing Zinc chloride as activator, 20%walnut shell, activation temperature 500℃, activation time 60 min, activation concentration 2.5 mol·L-1, dipping ratio 1:2.5.The biological sludge activated carbon is prepared that the iodine index is 574.11 mg·g-1 and the yield is 43.93%.
