Rapid decarbonization and coagulation integrated clarifying equipment

The invention provides rapid decarbonization and coagulation integrated clarifying equipment, which comprises a mixed reaction chamber, an internal reflux circulating reaction chamber, an external reflux circulating reaction chamber and a settling zone which are sequentially sheathed together. A reflux port which is communicated with the internal reflux circulating reaction chamber is arranged on the internal wall of the mixed reaction chamber. A closed small-resistance water distribution ring is arranged at the top of the internal reflux circulating reaction chamber. A water outlet hole which is communicated with the internal reflux circulating reaction chamber is arranged in a ring plate at the bottom of the water distribution ring. An internal reflux circulating turbulent flow mixing device is arranged in the internal reflux circulating reaction chamber. An external reflux circulating turbulent flow mixing device is arranged in the external reflux circulating reaction chamber. Since internal and external m
