Pyrolysis of urban plant sewage sludge has been demonstrated to be an effective way to produce fuel gas. However, a complete disposal of this particular waste is not achieved if the solid residues from the treatment are not considered. In this paper we discuss the feasibility an integrated pyrolysis/vitrification/sintering approach, aimed at a "full" disposal: the pyrolysis residues are first converted into a glass, then transformed into glass-ceramics, by simple viscous flow sintering treatments, with or without additions of inexpensive recycled glasses and kaolin clay. The obtained products were demonstrated to constitute an alternative to natural stones, in terms of both mechanical strength and chemical stability.
城市植物污水污泥的热解已被证明是生产燃料气的有效方法。然而，如果不考虑处理后的固体残渣，这种特殊废物的完全处理是无法实现的。在本文中，我们讨论了一种综合的热解/玻璃化/烧结方法的可行性，旨在实现“完全”处置：热解残渣首先被转化为玻璃，然后通过简单的粘性流烧结处理转化为玻璃陶瓷，添加或不添加廉价的回收玻璃和高岭土。所得到的产品在机械强度和化学稳定性方面被证明是天然石材的替代品。
