The management of one tone of dry sludge (DS) is selected. 7 Maidao sewage treatment plant 麦岛污水处理厂 The sludge treatment and disposal steps are gravity thicking, anaerobic digestion, dewatering, and agricultural use. 污泥处理处置步骤为重力浓缩、厌氧消化、脱水、农业利用。 This data set describes the process used at the Maidao sewage treatment plant for the treatment and disposal of municipal sludge. The anaerobic digestion of dry sludge is intended for reducing the volume and mass of waste, biogas production, and potentially for energy recovery and soil amendment applications. This process can serve municipal waste management systems by transforming biodegradable sludge into stabilized products used in various sectors. 该数据集描述了麦岛污水处理厂用于处理和处置市政污泥的过程。干污泥的厌氧消化旨在减少废物的体积和质量，生产沼气，并可能用于能源回收和土壤改良应用。该过程可以通过将可生物降解的污泥转化为稳定产品，服务于市政废物管理系统，并用于各个部门。 MOmdbhx0LoLG09x6yKmcaUD6nlg.png Unit process, single operation None 无 None 无 None 无 None 无 None 无 Xu, C., Chen, W. & Hong, J.

Life-cycle environmental and economic assessment of sewage sludge treatment in China. Journal of Cleaner Production 67, 79–87 (2014). When using this data set for life cycle assessment, the selected functional unit is the management of one tonne of dry sludge (DS). Ensure the treatment process being compared in the life-cycle inventory is equivalent in the terms of the functional unit. For modeling purposes, explicitly account for all outputs, including any biogas produced during anaerobic digestion, and consider the final disposition of the digested sludge. Additionally, evaluate the local technological practices for potential variability in the data. 在使用此数据集进行生命周期评估时，选定的功能单位是管理一吨干污泥（DS）。确保生命周期清单中比较的处理过程在功能单位方面是等价的。在建模时，应明确计算所有输出，包括厌氧消化过程中产生的任何沼气，并考虑消化后污泥的最终处置。此外，评估本地技术实践中的潜在数据变异性。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Jin Sitian, 2331276@tongji.edu.cn 金思甜, 2331276@tongji.edu.cn 2331276@tongji.edu.cn 2331276@tongji.edu.cn 2024-03-26T16:47:22+08:00 2024-04-20T14:37:32.177148+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=09434133-fe20-49e1-88ba-9d08b3075d90&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 ['opt4ROkqig'] Free of charge for all users and uses Electricity Input 553.86 553.86 Measured electricity from landfill gas utilisation Output 2215.368 2215.368 Measured waste water - untreated Output 3.56 3.56 Measured methane (biogenic),methane (biogenic) Output 250.0 250.0 Measured The original text does not distinguish between biogenic and fossil, and according to experts, it is biogenic here. 原文未区分biogenic和fossil，根据专家判断此处为biogenic。 dinitrogen Output 10.08 10.08 Measured nitrogen,emission to air 氮气,排放到大气中 hydrogen Output 0.71 0.71 Measured hydrogen sulfide Output 0.43 0.43 Measured Sludge Input 1000.0 1000.0 Estimated one tone of dry sludge (DS) 1吨干污泥(DS)
