Chemical feeding reaction tank with chemical feeding flow guide device

The utility model provides a dosing reaction tank with a dosing guide device, which comprises a reaction tank provided with a cavity inside, a water inlet and a water outlet, the water inlet is communicated with a superior sedimentation tank through an external water inlet pipe, and a stirring blade connected with a power machine is arranged in the cavity of the reaction tank. The input end of the drainage pipe is communicated with the water inlet, the output end is located at the bottom of the reaction tank, a baffle is arranged in front of the output end, and a dosing port is formed in the external water inlet pipe. The wastewater entering and exiting the dosing reaction tank is changed into a bottom-in and top-out form from a previous top-in and top-out form through the drainage pipe, so that the flocculation and precipitation reaction time of a treatment agent and the wastewater is prolonged, and the normal effluent quality is ensured. The dosing port is arranged on the external water inlet pipe, so that
