摘　　要：In recent years, with the acceleration of urbanization progress, the rapid growth of urban sewage volume, urban sewage treatment plants generally show overload operation, scale expansion and quality and efficiency improvement have put forward incremental demand for its construction land. With the development of the city, the original planned sewage treatment plants located in the town edge or the suburbs are mostly gradually surrounded by new construction and development land, and the expansion is restricted. Underground sewage treatment plant has the advantages of land saving, environmental protection, small ground dirty gas and noise, and small impact on the ground landscape, which provides an effective way to alleviate the construction land shortage of urban sewage treatment plants in China. However, underground sewage treatment plants also have inherent disadvantages in flood control and drainage, such as entrance and exit, equipment lifting other exposed space, easy to cause flood pouring, becomes the key and difficult point of urban flood control and drainage;through the inlet pipe connected with urban sewage pipe network (or confluence sewage pipe network) overflow is easier to directly cause underground urban sewage treatment plant flooding, causing serious accidents and serious environmental pollution. Based on this, this article studies the key points and difficulties of structural design of underground sewage treatment plant for reference.
