Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an energy-saving and emission-reducing urban sewage treatment system. Background Art

[0002] Disinfection is required during urban sewage treatment. In the prior art, chlorine-containing disinfectants are generally added to the sewage to kill pathogenic microorganisms in the sewage through the strong oxidizing properties of chlorine.

[0003] However, the applicant found that only adding disinfectants without stirring and mixing the sewage resulted in the disinfectant not being able to mix quickly and evenly with the sewage, resulting in excessively long disinfection time, which in turn prolonged the sewage treatment time and caused energy waste. In addition, the open-air disinfection pool is easily affected by pollutants in the air. For this reason, we proposed an energy-saving and emission-reduction urban sewage treatment system.
