城市地下污水处理厂规模分类与工艺规模选择优化

近年来，随着我国城市地下污水处理厂开发建设类型的不断增多，地下污水处理厂已成为城市市政工程建设的发展趋势。目前，我国城市地下污水处理厂规模类型还没有明确的标准规范，无法准确表达各城市地下污水处理厂处理规模的差异性。通过对城市地下污水处理厂处理规模和工艺分析，基于K-means算法，提出城市地下污水处理厂规模划分方法。根据城市地下污水处理厂不同污水处理工艺规模与数量的正态拟合，得出各工艺处理规模的分布曲线，明确各工艺的适宜规模类型。研究内容为城市地下污水处理厂规划与设计及工艺选择提供了参考依据。

Scale Classification and Optimization of Selecting Process Scale of Urban Underground Sewage Treatment Plants

In recent years, with the increase of types of urban underground sewage treatment plants in China, underground sewage treatment plant has become the trend of urban municipal engineering construction. At present, there is no clear standard for classifying the scales and types of urban underground sewage treatment plants in China, and the differences of the treatment scale of underground sewage treatment plants in each city cannot be accurately expressed. By analyzing the treatment scales and processes of urban underground sewage treatment plants in China, this paper proposes a classification method for scales of urban underground sewage treatment plants based on the K-means algorithm. According to the normal fitting of scales and numbers of different treatment processes of urban underground sewage treatment plants, the distribution curve of different process scales is derived, and the appropriate scale of each process is clarified. This study provides a good reference for the planning, design and process selection of urban underground sewage treatment plants.
