Underground wastewater treatment plants (U-WWTPs) have emerged as a novel paradigm for urban wastewater pollutants management, offering benefits such as alleviating the Not-in-my-backyard (NIMBY) effect and utilizing land resources efficiently. China stands at the forefront, witnessing swift advancements in U-WWTP technology and deployment. However, the absence of a thorough understanding of their geographical distribution and operational characteristics could lead to misaligned planning and construction, resulting in inefficient resource allocation and treatment capacities for urban wastewater treatment. This dataset provides an up-to-date overview of the spatial distribution, process selection, and discharge standards for all U-WWTPs in China (with a total number of 201) constructed since 1995. To enhance comparative analysis, the dataset has been supplemented with information on conventional aboveground wastewater treatment plants (A-WWTPs), comprising a total of 2464 records, which enriches a more comprehensive evaluation of different wastewater treatment approaches. Utilizing this dataset can provide essential data support for the strategic management of urban wastewater systems and serve as a valuable reference for the paradigmatic renovation of existing wastewater treatment plants.
地下污水处理厂（U-WWTPs）已成为城市污水污染物管理的一种新范例，具有减轻邻避效应和高效利用土地资源等优点。中国处于领先地位，见证了U-WWTP技术和部署的迅速发展。然而，对其地理分布和运行特征缺乏全面了解可能导致规划和建设失调，造成城市污水处理资源分配和处理能力低下。本数据集提供了自1995年以来中国建成的所有U-WWTPs（总数为201个）的空间分布、工艺选择和排放标准的最新概况。为加强比较分析，该数据集补充了常规地上污水处理厂（A-WWTPs）的信息，共计2464条记录，丰富了对不同污水处理方法的更全面评估。利用该数据集可为城市污水系统的战略管理提供重要数据支持，并为现有污水处理厂的范式改造提供有价值的参考。
