【摘要】 随着污水厂生物技术的广泛采用,污泥的产量近年来明显增加,污水污泥的处理及处置是目前比较严重的问题。针对目前污水厂污泥传统处理方法如填埋、焚烧、填海及土地利用等存在的不足与弊端,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热解制油、制取燃料、堆肥土地利用、热解制取吸附剂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。更多还原

【Abstract】 Since the biological technology is applied widely, the amount of sewage sludge is obviously increasing in recent years. Therefore, the treatment and disposal of the sewage sludge is a serious problem at present. Aiming at the disadvantages of the traditional treatment ways of municipal sewage sludge, such as landfilling, incineratation, sea-filling and earth application, 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.更多还原
