摘　　要：为降低污水厂污泥干燥能耗,结合太阳能温室干燥技术和电厂烟气废热干燥技术,提出了烟气废热/太阳能预干化新工艺,构建了工艺流程并对工艺单元进行了确定,并通过烟气余热/太阳能预干化污泥中试试验结果进行了能量衡算。In order to reduce the energy consumption of sewage sludge drying, the new drying technology with flue gas waste heat and solar was presented by combining the drying technologies of solar greenhouse and flue gas waste heat from power plants. The process flow was constructed and the process units were determined. The energy balance calculation was carried out on the basis of the pilot result for drying sludge with flue gas waste heat and solar.
