城市污泥水热处理技术研究进展

Research Progress on Hydrothermal Treatment of Municipal Sludge

随着城市发展,城市污泥的安全处置备受关注。污泥水热处理技术能明显改善污泥的水分结构,提高污泥脱水性能。同时改善污泥的性质,提高泥饼后续利用效率。电解质的添加能进一步提高处理效果。污泥水热处理技术为今后城市生活污泥的热处理技术和泥饼的后续资源化利用提供了一定的技术支持和保障。

With the development of cities,the safe disposal of municipal sludge has attracted much attention.Hydrothermal treatment of municipal sludge can significantly improve the water structure of sludge and improve the sludge dewatering performance.At the same time this technology can improve the properties of sludge and improve the subsequent utilization efficiency of mud cake.The addition of electrolyte can further improve the treatment effect.The technology of hydrothermal treatment on sludge will provide certain technical support and guarantee for the future heat treatment technology of municipal sludge and the subsequent resource utilization of sludge cake.
