城市污泥结构特性及其能源化利用的分析与探讨

Structural Characteristics of Municipal Sludge and Its Energy Utilization

随着城市化进程的发展,城市污泥产量在大幅增长,对城市污泥开展能源化利用,不仅能够缓解生态环境压力,还能够实现污泥中热值的回收利用。综述了国内外学者对城市污泥结构特性的研究成果,分析了中国城市污泥能源化利用现状。污泥的絮体结构导致其水分含量很高,高水分含量使污泥的能源化利用难度增加,因此,改善污泥结构特性是推动污泥能源化利用的有效措施。

With the development of urbanization process, the output of municipal sludge is increasing greatly. The energy utilization of municipal sludge can not only relieve the pressure of ecological environment, but also realize the recycling and utilization of calorific value in sludge. This paper reviewed the research results of domestic and foreign scholars on the structural characteristics of municipal sludge, and analyzed the current situation of energy utilization of municipal sludge in China. The floc structure of sludge results in high water content, which makes the energy utilization of sludge more difficult. Therefore, improving the structure characteristics of sludge is an effective measure to promote the energy utilization of sludge.
