The output end diameter of the upper water distribution pipe 39 is smaller than the diameter of its upper part. A baffle 40 is provided on the upper part, and the gap between the baffle 40 and the upper water distribution pipe 39 is used to discharge clean water.

[0026] During operation, the dosing device 3 stores flocculating agents and backwashing agents. The coagulation acceleration device 2 mixes the raw water with agents through the drug outlet of the dosing device 3 and then inputs it into the steady flow deceleration flocculation device 4. The mixed liquid of the agents and the raw water hits the clean water tank 9 in the steady flow deceleration flocculation device 4 and mixes in the space between the steady flow deceleration flocculation device 4 and the clean water tank 9.

The low-temperature mixed liquid between the steady flow deceleration flocculation device 4 and the clean water tank 9 is fully mixed to further evenly distribute the agent, ensuring a more complete reaction between the agent and impurities in the water. The precipitation efficiency of the mixed liquid in the precipitation device 5 is improved.
