[0002] The treatment of desulfurized wastewater mainly involves steps such as neutralization, precipitation, flocculation, concentration, and clarification. Desulfurized wastewater mainly comes from the discharged water of the absorption tower during the wet desulfurization of boiler flue gas (limestone / gypsum method), and contains impurities such as suspended solids and supersaturated sulfites.

[0003] The existing Chinese patent with the authorized announcement number CN216445036U discloses an automatic calcium hydroxide dosing device for desulfurized water treatment, including a dosing device main body. A fixing frame is welded to the inner wall of the dosing device main body. A slider chute is provided on the side of the fixing frame. A slider is slidably connected inside the slider chute. A sieve plate is fixedly installed on the side of the slider. A vibration motor is arranged at the bottom of the sieve plate to prevent caked drugs from entering the treatment tank and affecting the normal reaction of the drugs. The bottom of the dosing device main body is fixedly connected with a discharge pipe. The bottom of the discharge pipe is fixedly connected with a treatment tank. A control frame is arranged outside the discharge pipe. Rotating motors are arranged on the left and right sides of the control frame.
