广州市污泥处理处置技术路线及其经济性分析

X705; 详细介绍了广州市城市污泥的产生、危害及处理现状。结合我国污泥处理规范化路线，对5种处理工艺进行了重点讨论。根据降低成本、节能降耗的原则对广州市目前的组合技术及各路线的经济性进行比较，得出广州市污泥处理处置的组合技术路线为“浓缩＋机械脱水＋热干化→异地或就地处置”，其中污泥干化单位投资总成本为190万元／tDS，运行总成本为19660元。该技术路线有望成为缓解广州市污泥处理处置的规范化路线。...

Summary:X705; 详细介绍了广州市城市污泥的产生、危害及处理现状。结合我国污泥处理规范化路线，对5种处理工艺进行了重点讨论。根据降低成本、节能降耗的原则对广州市目前的组合技术及各路线的经济性进行比较，得出广州市污泥处理处置的组合技术路线为“浓缩＋机械脱水＋热干化→异地或就地处置”，其中污泥干化单位投资总成本为190万元／tDS，运行总成本为19660元。该技术路线有望成为缓解广州市污泥处理处置的规范化路线。
Bibliography:The production, damage and treatment of municipal sewage sludge in Guangzhou city are dis-cussed in detail. In combination with the standardization of sludge treatment in China, 5 processing tech-niques are discussed. According to the principle of reducing cost, saving energy and reducing consump-tion ,current combination technology of Guangzhou and the economic performance of the routes are com-pared. It is concluded that the combined technical route of sludge treatment and disposal in Guangzhou is “ concentration ＋ mechanical dehydration ＋ thermal dry→ off-site or in-site disposal” , and the unit invest-ment cost of sludge drying is 1,900,000 yuan /tDS, the total cost of operation is 19,660 yuan. The tech-nical route is expected to become the standardized route for Guangzhou municipal sludge treatment and disposal.
