At the outer peripheral top of the efficient reactor 1, there is a protective mechanism 3 which facilitates the climbing and walking of the staff. Outside the efficient reactor 1, there is a water inlet tank 4 which is made of a wastewater buffer tank using existing technology. On the adjacent side of the water inlet tank 4 outside the efficient reactor 1, there is a hydrocyclone clarifier 5. The hydrocyclone clarifier 5 is a device for solid-liquid separation, mainly using the action of centrifugal force and gravity to separate the solid particles in the suspension from the liquid, so as to achieve the purpose of clarifying the liquid. On one side outside the hydrocyclone clarifier 5, there is a sludge pool 6 which is used to temporarily store sludge. On the side of the efficient reactor 1 outside and away from the water inlet tank 4, there is a vacuum belt filter 7. The slurry on the vacuum belt filter 7 is used to mix with the sludge for desulfurization gypsum removal, reducing environmental sludge and operating costs. The equipment power consumption cost per ton of wastewater is saved by about 10.19 yuan / t, and the cost of chemicals and spare parts per ton of wastewater is saved by about 15.3 yuan / t, saving costs. On the side of the hydrocyclone clarifier 5 outside and away from the sludge pool 6, there is a clear water tank 8 which is used to store clear water. Outside the sludge pool 6, there is a second transfer pump 10 which can pump out the sludge. The output end of the second transfer pump 10 is fixedly connected with a sludge discharge pipe 12 which plays a connecting role.

The desulfurization wastewater system realizes one-key startup, controls the full-process automatic operation and real-time monitoring of the system, greatly reduces manual intervention and labor intensity. The number of manual workers for sludge treatment is reduced from the original two to no manual input. When treating wastewater, first open the electric valve, and then the wastewater in the inlet water tank 4 will enter the interior of the high-efficiency reactor 1. The high-efficiency water purifying agent is added through the feeding and stirring mechanism 2, and the wastewater can be stirred inside the high-efficiency reactor 1 through the feeding and stirring mechanism 2. After the wastewater fully reacts into flocs, open the solenoid valve, and then it flows by gravity through the overflow port of the high-efficiency reactor 1 to the hydrocyclone clarifier 5 for hydrocyclone clarification. After clarification, the clear water flows out through the opened automatic valve from the overflow port of the hydrocyclone clarifier 5 and enters the clear water tank 8 through the drain pipe 14. Open the first transfer pump 9. The input end of the first transfer pump 9 sucks the bottom sludge of the hydrocyclone clarifier 5 through the inlet mud pipe 11 and discharges it through the output end of the first transfer pump 9 into the interior of the sludge tank 6. Then open the second transfer pump 10. The input end of the second transfer pump 10 sucks the sludge in the sludge tank 6 and discharges it through the output end of the second transfer pump 10 into the interior of the sludge discharge pipe 12 and enters the vacuum belt filter 7. By adjusting the frequency of the second transfer pump 10, it is fully mixed with the slurry of the vacuum belt filter for desulfurization of gypsum.

A driven bevel gear 207 is fixedly connected to the side of the rotating rod 208 close to the driving bevel gear 206. The driving bevel gear 206 can drive the driven bevel gear 207 to rotate, and the driven bevel gear 207 is meshed with the driving bevel gear 206. A plurality of dispersing frames 209 are fixedly connected to the outside of the rotating rod 208. After the rotating rod 208 drives the dispersing frames 209 to rotate, the agglomerated high-efficiency water purifying agent can be dispersed. A top cover 212 is arranged on the top of the dry powder feeder 211, and a handle is fixedly connected to the top of the top cover 212, which is convenient for picking up the top cover 212. After the wastewater is introduced into the feeding and stirring mechanism 2, the motor 202 is started. After the output end of the motor 202 rotates and is decelerated by the speed reducer 203, it drives the rotating shaft 204 to rotate. After the rotating shaft 204 rotates, it drives the stirring frame 205 to rotate, so as to stir the wastewater and the high-efficiency water purifying agent poured into the wastewater, accelerating the mixing of the wastewater and the high-efficiency water purifying agent. When the high-efficiency water purifying agent is added into the dry powder feeder 211, the driving bevel gear 206 can be driven to rotate by the rotation of the output end of the motor 202. After the driving bevel gear 206 rotates, it can drive the driven bevel gear 207 to rotate. After the driven bevel gear 207 rotates, it can drive the rotating rod 208 to rotate. After the rotating rod 208 rotates, it drives the dispersing frames 209 to rotate, so as to pre-disperse the high-efficiency water purifying agent added into the dry powder feeder 211, preventing the agglomerated high-efficiency water purifying agent from affecting the reaction speed of the wastewater and the high-efficiency water purifying agent after being added into the wastewater.

[0025] The protection mechanism 3 includes a top plate 301. The middle of the top plate 301 is fixedly connected to the outer peripheral top of the high-efficiency reactor 1.

[0026] Working principle: When treating wastewater, first open the electric valve. At this time, the wastewater in the water inlet tank 4 will enter the interior of the high-efficiency reactor 1. Then, add a high-efficiency water purifying agent through the feeding and stirring mechanism 2, and the feeding and stirring mechanism 2 can stir inside the high-efficiency reactor 1, so that the wastewater fully reacts into flocs. Then, open the solenoid valve, and the wastewater will flow by gravity through the overflow port of the high-efficiency reactor 1 to the cyclone clarifier 5 for cyclone clarification. After clarification, the clear water will flow out through the overflow port of the cyclone clarifier 5 by opening the automatic valve and enter the clear water tank 8 through the drain pipe 14. Open the first transfer pump 9. The input end of the first transfer pump 9 sucks the bottom sludge of the cyclone clarifier 5 through the sludge inlet pipe 11 and discharges it through the output end of the first transfer pump 9 into the interior of the sludge tank 6. Then, open the second transfer pump 10. The input end of the second transfer pump 10 pumps the sludge in the sludge tank 6 and discharges it through the output end of the second transfer pump 10 into the interior of the sludge discharge pipe 12 and enters the vacuum belt filter 7. By adjusting the frequency of the second transfer pump 10, it is fully mixed with the slurry of the vacuum belt filter for desulfurization of gypsum; After the wastewater is introduced into the interior of the feeding and stirring mechanism 2, start the motor 202. After the output end of the motor 202 rotates and is decelerated by the speed reducer 203, it drives the rotating shaft 204 to rotate. After the rotating shaft 204 rotates, it drives the stirring frame 205 to rotate, so as to stir the wastewater and the high-efficiency water purifying agent poured into the wastewater, accelerating the mixing of the wastewater and the high-efficiency water purifying agent. When the high-efficiency water purifying agent is added into the interior of the dry powder dosing machine 211, it can drive the driving bevel gear 206 to rotate under the rotation of the output end of the motor 202. After the driving bevel gear 206 rotates, it can drive the driven bevel gear 207 to rotate. After the driven bevel gear 207 rotates, it can drive the rotating rod 208 to rotate. After the rotating rod 208 rotates, it drives the dispersing frame 209 to rotate, so as to pre-disperse the high-efficiency water purifying agent added into the dry powder dosing machine 211, preventing the caked high-efficiency water purifying agent from affecting the reaction speed between the wastewater and the high-efficiency water purifying agent after being added into the wastewater.
