Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] like figure 1 An urban sewage purification method is shown, and the sewage purification method includes the following steps: (1) collection process: the sewage is passed through the sewage pipe and the grid, and the larger floating objects in the sewage are cleaned and intercepted, and then After passing through the grit chamber, impurities such as sand and solid particles in the sewage are removed, and the cleaned sewage is collected into the reservoir. The grid is provided with a coarse grid and a fine grid, and the coarser grid is removed through the coarse grid The finer solid floating matter is removed through the fine grid, and then the sand and gravel can be removed through the grit chamber, which can clean the floating matter and sand in the water, and prevent the floating matter, sand and solid particles from being transported in other sewage In the mo...
