污水处理厂污泥富含多种有机、无机成分,经热解碳化,可制备用于水处理的吸附剂,是实现污泥资源化的有效途径之一.污泥吸附剂的孔结构特征和化学性质是决定其去除污染物效能的关键因素.介绍了国内外有关热解碳化制备污泥吸附剂的方法、制备条件、污泥吸附剂去除污染物机制,以及针对不同类型污染物增强污泥吸附剂相应功能的技术途径和方法,分析了不同方法的优缺点.%sludge form sewage treatment plant is rich in variety of organic and inorganic constituents;therefore, using the pyrolytic carbonized sludge to prepare water treatment adsorbent is one of the effective ways to realize sludge reutilization. The pore structure features and chemical characteristics are the key factors that de-termines the pollutants removal efficiency. The methods and conditions for sludge adsorbent preparation using pyrolysis carbonization adopted by China and abroad were introduced, and then, the mechanism of the sludge ad-sorbent removing pollutants was pointed out. Additionally, according to different types of pollutants, technical ap-proaches and methods were adopted to enhance the corresponding performance of the sludge adsorbents, and the advantages and disadvantages of different methods were explained finally.
