A turntable 15 is connected to the top of plate 14. Two feeding tanks 16 are fixedly connected to the turntable 15. A discharge pipe 17 is fixedly connected to the feeding tank 16. A second electric valve 18 is installed on the discharge pipe 17. A weight sensor 19 is installed on the feeding tank 16 to detect the weight of sulfuric acid or hydrochloric acid. A filter box 20 is fixedly connected to the fixed plate 1. A drain pipe is connected to the filter box 20 and the discharge pipe 9. A filter screen 21 is fixedly connected inside the filter box 20 to filter wastewater. The filter box 20 is equipped with multiple ultraviolet germicidal lamps 22, which are used to sterilize the wastewater. Two first electric push rods 23 are fixedly installed on the filter box 20. The first electric push rods 23 are connected to the telescopic rods of the first electric push rods 23 and the first connecting rods 24 are slidably connected to the filter box 20. A pusher plate 25 is connected between the two first connecting rods 24. The pusher plate 25 is used to push impurities. A third electric valve 29 is installed on the drain pipe of the filter box 20. A second liquid level sensor 30 is installed inside the filter box 20.

[0022] A buzzer is installed on the controller 101.

[0023] The inside of the feeding tank 16 is provided with an inclined surface.

[0024] The pusher plate 25 is equipped with an anti-corrosion coating.

[0025] Two second electric push rods 26 are fixedly installed on the filter box 20.

[0026] The working principle of this utility model is as follows: Sulfuric acid or hydrochloric acid is added to the feeding tank. When the sulfuric acid or hydrochloric acid in the feeding tank reaches the preset threshold of the weight sensor, a buzzer is activated to remind the user to stop adding sulfuric acid or hydrochloric acid. Then, wastewater is injected into the treatment tank through the feed pipe. When the liquid level of the wastewater in the treatment tank reaches the preset threshold of the first liquid level sensor, the buzzer is activated again to remind the user to stop adding wastewater. Subsequently, the second drive motor drives the second rotating shaft, turntable, feeding tank, and discharge pipe to rotate, so that the discharge pipe rotates above the feed pipe. Then, the second electric valve opens the discharge pipe, and sulfuric acid or hydrochloric acid flows into the treatment tank through the discharge pipe and mixes with the wastewater. The pH value of the wastewater is adjusted to neutral by adding sulfuric acid or hydrochloric acid to avoid corrosion of subsequent equipment and to create suitable conditions for subsequent treatment. The first drive motor drives the first rotating shaft and agitator to rotate. The agitator stirs the wastewater, thereby improving the wastewater treatment efficiency.

[0027] After wastewater treatment, the first electric valve opens the discharge pipe, allowing wastewater to flow into the filter box. The wastewater then falls onto the filter screen, which filters out impurities. The filtered wastewater flows to the bottom of the filter box. When the wastewater level in the filter box reaches the preset threshold of the second level sensor, the first electric valve closes the discharge pipe, simultaneously activating the ultraviolet germicidal lamp to sterilize the wastewater. After sterilization, the third electric valve opens the filter box drain pipe, allowing the treated wastewater to flow out. Then, the second electric push rod raises the second connecting rod and the sealing plate, opening the filter box outlet. Next, the first electric push rod moves the first connecting rod and the pusher plate, pushing the impurities off the filter screen from the filter box, thus completing the filtration process.
