The tank body is designed into a commonly-called double-layer capping mode, namely the tank body is capped to meet the deodorization requirement, and the tank surface maintenance space is capped and isolated from the underground to create a good ground environment. Daily field operation and maintenance are mainly performed in underground spaces. The operators can often carry out production activities such as daily inspection, operation, maintenance and the like in the underground space. The typical form of the vertical section is generally divided into three layers: the underground negative two layers (a sewage treatment structure tank layer), the underground negative one layer (a treatment tank surface layer, a production auxiliary building layer and a production operation management space layer) and the ground layer (a ground other use layer).
