A dosing device for sewage treatment

Abstract

This invention discloses a dosing device for wastewater treatment, relating to the technical field of wastewater treatment devices. The structure includes a feeding tank with a feeding pipe on its side wall. An annular input pipe is located inside the feeding tank, communicating with the feeding pipe. A mounting base is rotatably mounted inside the feeding tank, and a stirring mechanism is installed on the mounting base. Multiple discharge ports opposite to the stirring mechanism are opened on the inner side of the input pipe. A backflushing assembly for backflushing the liquid is also provided inside the feeding tank. This backflushing assembly allows the stirring mechanism to simultaneously stir the wastewater and the chemicals, while also backflushing the wastewater and chemicals, resulting in a more uniform mixing of the chemicals within the wastewater, thereby improving the wastewater treatment effect.
