城市污水处理厂在处理污水的同时会产生大量的污泥,其含有大量有机物和有害物,性质不稳定,易腐化,如果处理不当,将会造成严重的环境污染和资源浪费.用城市污水处理厂污泥制备活性炭是20世纪80年代后期出现的一种新型利用途径,因其制备成本低,活性炭用途广泛,可以用于污水处理去除有毒有害物质,具有良好的环境效益和社会效益,引起国内外研究人员的关注.而有毒重金属对环境的严重威胁正逐渐成为全球性问题,活性炭吸附法是一种常用来处理重金属废水的方法.综述了国内外污泥制备活性炭的工艺方法,及在这些制备方法基础上对重金属废水的处理研究.

In recent years, large numbers of municipal sludge are produced during the disposal of city water, which contain a lot of organic matter and harmful substances, their nature unstable and easily degenerate. If not handled properly, it will cause serious environmental pollution and waste of resources. With urban sewage sludge on the preparation of activated carbon is a new way to use in the late 1980s, it caused a lot of concern because of low cost, widespread use of activated carbon, can be used for sewage treatment to remove toxic and harmful substances, has a good environmental benefits And social benefits. However, the toxic heavy metals pose a serious threat to the environment is becoming a global problem, activated carbon adsorption is a common method to deal with the heavy metal waste water method. This paper reviews the preparation process of activated carbon sludge at home and abroad, and heavy metal waste water treatment study on the basis of these preparation methods.
