市政污泥处理与处置;湿污泥 含水率80%;干化焚烧
数据集使用建议 在使用该数据集进行生命周期评估时，重要的是要将描述的单元过程作为污泥管理系统内的独立操作。考虑干化和焚烧阶段所需的能源和资源输入，以及过程产生的排放和残余物。用户应确保数据集适用于污泥处理的地理和技术背景，并针对实践或规模上的任何差异进行校正。此外，如果考虑循环利用或处置后的环境影响，这些方面必须单独地整合到整体的生命周期评价框架中。
产品或过程的技术目的 描述的工艺属于市政污泥的处理与处置。这些污泥具有高含水率80%，需要经过干化后进行焚烧处理。这是一个单元过程（单一操作），能够处理特定水分水平的湿污泥。常用于污水处理厂副产品的管理，并且是在最终处置之前减少污泥体积的关键步骤。

技术代表性
技术说明，包括后台系统 湿污泥首先进入污泥干燥机进行干燥处理，从含水率 80%干燥至 50%；干燥后的污泥送入流化床进行燃烧，流化床温度在 850~1 000 ℃之间；燃烧产生的高 温烟气进入空气预热器，预热后的空气进入流化床作为助燃空气；从空气预热器出来的烟气进入余热锅炉加热锅炉给水，由余热锅炉产生的高温蒸汽（0.8 MPa, 200 ℃）进入污泥干燥机作为热源对污泥进行干燥，冷却后的烟气经除灰除尘处理后排放。
