| 摘 要： | 随着城市污水处理厂不断增加,城市污泥的产量也大幅度增长。减量化是城市污泥资源化的首要步骤,而干燥是城市污泥减量化最有效的方法之一。本文简述了城市污泥的干燥特性及各种干燥方法,并对各种方法的优缺点进行比较,得出利用太阳能和通过种植植物对污泥进行干燥是较为经济可行的污泥干燥方法。在提倡可持续发展理念及能源危机不断恶化的情况下,这两种方法在污泥干燥方面的应用将具有广泛前景。

| Abstract: | The production of municipal sludge has been sharply increasing with more and more municipal sludge treatment plants in China. Volume reduction is the first step on resource utilization of municipal sludge, and drying is the most efficient way for the volume reduction of municipal sludge. This paper reviews the drying characteristics of municipal sludge and its various drying means, and concluded that drying sludge by sunlight and plants were more economic and feasible than other drying methods for municipal sludge. These two methods will have bright future in sludge drying, as calling for sustainable development and energy shortage are getting more and more serious. |
