剩余污泥为污水处理厂副产物，具有成分复杂难处理，易滋生二次污染的特性。主要介绍了近年来剩余污泥制吸附剂和能源化技术的研究进展。由于剩余污泥中有机质含量丰富，首先对单一污泥和剩余污泥添加工农业废弃物制备吸附剂的研究现状进行了介绍，指出吸附材料制备过程中活化剂大量使用会造成环境的再污染；随后综述了剩余污泥直接能源化，或通过热解等手段将其间接能源化的研究进展；最后提出用生物质废弃物代替化学活化剂制备污泥吸附剂的研究思路，并指出将污泥制备材料和能源利用技术相结合是今后剩余污泥资源化研究的主要发展方向。
Excess sludge is the byproduct of the sewage treatment plant,which has the complex composition, difficult to dispose of,and could easily breed secondary pollutants characteristics.This paper mainly describes the re-search progress of using excess sludge for sorbent manufacturing and energy utilization technology in recent years. Since excess sludge is rich in organic matter,the paper will first introduce the research status on absorbent manufac-turing from single sludge and excess sludge in combination with agricultural and industrial waste,and it will cause the recontamination of environment due to extensive use of activating agents in the absorbent manufacturing process.Then the paper will go on to summarize the research progress of excess sludge in direct energy utilization,or indirect energy utilization by means of pyrogenic decomposition.In the end,we propose the idea that using biomass waste take the place of chemical activating agents in preparation of sludge absorbents.And it is indicated that the combination of sludge materialization and energy utilization technology will become the mainstream direction in excess sludge re-sources.
