[0002] The flocculation reactor used for water treatment is a key equipment for treating suspended matter and turbidity in water, especially playing an important role in sewage treatment and drinking water purification. Flocculation is achieved by adding flocculants, such as aluminates or polymers and other chemical substances, to make tiny suspended matter particles in the water condense into larger floccules, which are convenient for subsequent sedimentation or filtration treatment to ensure treatment effect and stability. It is combined with sewage treatment plants, drinking water treatment plants, industrial wastewater treatment and other fields, and can adapt to various water quality and treatment requirements through different designs and configurations.

[0003] Currently, flocculation reactors on the market generally lack stirring devices, which is not conducive to the mixing of reagents and water to be treated, and is not convenient for throttling control according to the pH value of the water.
