城市污水处理厂污泥资源化研究探讨

Approach to the Utilization of Sludge from Municipal Sewage Treatment Plants

城市污水污泥产量巨大且成分复杂,如何对它进行合理利用已越来越受人们关注,若处置利用不当就不能够充分发挥其消除污染、保护环境的作用,也就明显地削弱了污水处理厂的净化功能。文章系统地综述了城市污泥处置与利用的现状和趋势,指出污泥资源化利用是今后污泥最终处置的根本方式,并就目前研究较多的污泥制作建筑材料、热解制油、制取燃料、堆肥利用、等资源化利用技术及前景进行了分析,为今后污泥的资源化利用提供参考。

The productivity of city sludge is very huge and its components are completed. It＇s an attractive problem that how to deal with it efectively. It can weaken the purified function of the sewage factory if the city sludge Can not be deposed right.The paper reviewed the tendency an d the actuality of the disposal and reuse of city sludge, it is put forward that resource utilization technique will be the main way of the final disposal of sludge. The technologies of sludge pyrolysis for oil producing,fuel producing,compost land utilization, adsorbent producing, etc. are analysed, providing reference to the resource utilization of sludge in the future.
