Method for treating pollution point sources of rivers and lakes by clear water type water ecosystem

The invention discloses a method for treating a river and lake pollution point source by a clear water type water ecosystem, which comprises the following steps: selecting a vertical internal circulation integrated sewage treatment equipment placement point in a flat area with lower terrain according to the field terrain and landscape design requirements of the river and lake pollution point source; sewage enters the sedimentation tank through the local collection pipe network, and the sewage is guided into the vertical internal circulation integrated sewage treatment equipment after standing in the sedimentation tank; sewage is treated by the vertical internal circulation integrated sewage treatment equipment for a first time and then discharged into a clear water type water ecological system; and constructing a clear water type water ecosystem. According to the invention, after sewage is treated at the front end of the vertical internal circulation integrated sewage treatment equipment, point source sewage
