[0014] The stirring mechanism allows the flocculant and sewage to be fully and quickly mixed.
[0015] A wastewater treatment device for a thermal power plant, the adsorption device comprises a protective shell 12, an inner shell 13, an end cover A14, and an end cover B15, a drain outlet 16 and a sewage outlet 17 are respectively arranged below the surface of the protective shell, and the two ends are fixedly connected to the end cover A and the end cover B, the interior of the protective shell is connected to the inner shell through a fixing plate 18, a Jiaolong drum 19 is installed in the inner shell, the end of the Jiaolong drum is fixedly connected to a water filter cover 20 near the end cover A, the end of the Jiaolong drum away from the water filter cover is connected to the coupling 21 through the end cover B through a pipe, and the central tube of the Jiaolong drum is provided with three water outlets, and the coupling is connected to the motor B22.
[0016] The sewage containing sediment is pumped into the adsorption mechanism by the driving force of the high-pressure pump, and the sewage enters the inner shell from the water outlet of the Jiaolong drum. The motor B is used as the driving force to drive the Jiaolong drum to move continuously. Due to the specific gravity difference between solid and liquid, the sediment is adsorbed on the inner wall of the inner shell through the centrifugal force generated. Then, the sediment is discharged from the sewage outlet after continuous rotation, and the treated water is discharged from the drain outlet through the water filter cover.
[0017] The wastewater treatment device of a thermal power plant, the discharge mechanism includes a drainage chamber 23 and a sewage chamber 24, a high-precision filter 25 is installed inside the drainage chamber, a drainage pipe 26 is arranged at the rear lower part, the sewage chamber is provided with a sewage pipe 27, and an electric push plate 28 is arranged inside the discharge port.

[0019] Working principle: The desulfurized wastewater to be treated is discharged from the water inlet into the mixing barrel, and then flocculants are added from the flocculation box. The flocculants enter the mixing barrel through the drug guide tube and mix with the wastewater. At this time, start motor A, which is the driving force to rotate the stirring rod to fully blend the flocculant and wastewater. After completing this step, start the high-pressure pump, open the control valve, and the mixed wastewater reaches the water outlet of the Jiaolong drum in the adsorption mechanism through the pipeline and enters the inner shell. Start motor B, which is the driving force to drive the Jiaolong drum to move continuously. The centrifugal force generated at this time will adsorb the sediment on the inner wall of the inner shell, and then continue to rotate. The sediment will be discharged from the sewage outlet to the sewage cavity. Starting the electric push plate can discharge the sediment into the sewage pipe; the treated water will be discharged from the drain outlet to the drainage cavity through the water filter cover. The treated water passes through the high-precision filter in the drainage cavity and is discharged from the drainage pipe.
