Data underlying the research of the Recovery and Characterization of Extracellular Polymeric Substances from Activated Sludge

1) Research objective: Our research focuses on the extraction and characterization of extracellular polymeric substances (EPS) from activated sludge. All the samples primarily activated sludge, are collected from lab-scale and full-scale wastewater plants. 2) Data collection and type: The data type is the results associated with the chemical and physical characteristics of sludge and EPS samples. All chemical and physical measurements are based on laboratory instruments. Specifically, after collection, the hot alkaline protocol is applied to extract EPS. Subsequent analyses include total proteins and total sugars, functional groups, monosugars, staining methods, and microscopic visualization, all conducted following standard methods. 3) Data statistic: Raw data is analyzed and designed using the Excel and Origin software. No scripts and relevant coding methods are used in our research. Further analysis of the results and mechanism can be found in the main text of the thesis. <br>

1) 研究目标：本研究聚焦于从活性污泥中提取并表征胞外聚合物（extracellular polymeric substances，EPS）。所有样本以活性污泥为主体，采集自实验室规模与全规模污水处理厂。2) 数据采集与类型：本数据集涵盖污泥与EPS样本的理化特性相关测试结果。所有理化检测均依托实验室仪器完成。具体流程为：样本采集完成后，采用热碱法提取EPS；后续分析项目包括总蛋白质、总糖含量、官能团表征、单糖组成、染色实验以及显微可视化观测，所有分析均遵循标准方法开展。3) 数据统计：原始数据采用Excel与Origin软件进行分析与设计。本研究未使用脚本或相关编码手段。针对研究结果与作用机制的进一步分析，请参见论文正文部分。
