摘　　要：采用热干化工艺处理福建某开发区污水处理厂的剩余污泥,处理能力为12 t/d。一年多来的稳定运行结果表明,该技术能快速降低污泥含水率至30%以下,污泥减量率达71%,且干化过程中尾气的恶臭及二口恶英指标均符合国家标准。该工程总投资为226.67万元,运行成本为195.62元/t污泥。A sludge thermal drying process is adopted to treat excess sludge in a wastewater treat- ment plant in a development zone in Fujian Province. The treatment capacity was 12 t/d. The treatment result over one year shows that the thermal drying process could quickly reduce the water content of sludge to below 30% , and reduce the amount of sludge to 71%. The odor and dioxin index of exhaust gas in the drying process met the national standard. The total investment of this project is 2. 266 7 million Yuan, and the operation cost is 195.62 Yuan per ton of sludge.
