Up to now, many of our country's sewage treatment plant in the work of this process will be incorporated as the primary work technology for application. 循环活性污泥工艺是以SBR技术基础上发展而成的一种新型的污水生物处理工艺，这种方法的应用是结合社会发展和先进科学技术为基础的一种综合性的污水处理收集措施和处理工艺，并且在其工作中有良好的工作优势与广泛的应用。截至当前，我国多个污水处理厂在工作中都纳入了这种工艺将其作为首要工作技术进行应用。 11 2014 2014 Chatuchak,Thailand Recirculating activated sludge technology consists of the following processes:Intake and mixing: wastewater is introduced into the treatment system and mixed with activated sludge already present in the reactor.Biodegradation: The mixed wastewater comes into contact with the activated sludge in the reactor, where microorganisms degrade the organic substances in the wastewater into water and carbon dioxide.Sedimentation: The treated water is settled over a period of time so that the sludge particles settle to the bottom to form sludge deposits.Return flow: A part of the activated sludge that has been settled is returned to the reactor to maintain the number and activity of microorganisms in the sludge.Discharge: The treated water is discharged through the outlet and the clean water is released into the environment. 循环活性污泥技术包括以下过程：进水和混合：废水被引入处理系统，并与已经存在于反应器中的活性污泥混合。生物降解：混合后的废水在反应器中接触到活性污泥，微生物将废水中的有机物质降解为水和二氧化碳。沉淀：处理后的水经过一段时间的沉淀，使污泥颗粒沉降到底部形成污泥沉积物。回流：一部分已经沉淀的活性污泥被回流到反应器中，以保持污泥中的微生物数量和活性。排放：经过处理后的水通过出水口排放，清洁水被释放到环境中。 The Cyclic Activated-Sludge Technology described in this data set is used for municipal wastewater treatment to remove contaminants and produce environmentally safe treated wastewater. It is typically implemented as a part of municipal wastewater treatment plants. 本数据集描述的循环活性污泥技术用于市政污水处理，以去除污染物并产生环境安全的处理过的污水。它通常作为市政污水处理厂的一部分进行实施。 Unit process, black box None 无 None 无 None 无 None 无 None 无 Polruang, S., Sirivithayapakorn, S. & Prateep Na Talang, R.

Since the data is specific to the Chatuchak area in Thailand, adjustments may be needed for differing technological standards, local environmental regulations, or wastewater composition when applying this data to other regions. Additionally, users should consider the boundaries of the unit process defining what is included in the system ('black-box' approach) and what falls outside its scope. 本数据集的用户应考虑该流程与应用地区情境的地理及技术相关性。由于数据特定于泰国Chatuchak地区，当将此数据应用于其他地区时，可能需要针对不同的技术标准、当地环境法规或污水组成进行调整。此外，用户应当理解单元过程的边界定义，了解系统内包含的内容（“黑箱”方法）及其范围之外的内容。 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 YU Chenyang, yuchenyang0506@foxmail.com 于晨阳, yuchenyang0506@foxmail.com yuchenyang0506@foxmail.com yuchenyang0506@foxmail.com 2024-03-27T14:58:34+08:00 2024-04-20T14:37:13.423083+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=54b1e7cf-470d-44ef-aa4d-9ac94f84b10e&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 Waste (solid) Output 0.0015 0.0015 Measured nitrogen, total (excluding N2) Output 0.0078 0.0078 Measured phosphorus, total Output 0.0012 0.0012 Measured Suspended solids, unspecified,Suspended solids, unspecified,Suspended solids, unspecified Output 0.0053 0.0053 Measured chemical oxygen demand Output 0.022 0.022 Measured biological oxygen demand Output 0.0043 0.0043 Measured nitrous oxide Output 0.00014 0.00014 Measured carbon dioxide (biogenic) Output 0.0146 0.0146 Measured The original text does not provide information on biogenic and fossil sources.
