[0033] See also Figure 1 to Figure 7 Preparation before water purification: add the corresponding solution into the two regulating tanks 11 and turn on the stirring paddle 132 for mixing, close all valves 7, and open the valve 7 on the discharge pipe 131 below, so that the prepared sewage treatment agent is discharged into the storage barrel 51 and the discharge ring 52, and then start water purification.

[0034] Adjust the pH value of the sewage: allow the sewage to flow through the feed pipe 14 and the rotating rod 3 and then enter the regulating tank 11 from the discharge hole 33, turn on the driving member 23, and allow the sliding block 321 to drive the rotating ring 323 to rotate and lift.

After mixing for a period of time (10~20min), observe the pH sensor and choose whether to continue adding the regulator according to actual conditions (although there will be a certain amount of sewage in the rotating rod 3 during the adjustment process, as the sewage in the regulating tank 11 fluctuates, the sewage in the rotating rod 3 will continuously exchange with the sewage in the regulating tank 11 until the pH value stabilizes).

[0035] Using sewage treatment agent to purify water: open the valve 7 on the rotating rod 3 between the regulating tank 11 and the mixing tank 12, the sewage in the regulating tank 11 will enter the rotating rod 3 through the discharge hole 33 and flow downward, and when the sewage flows out of the rotating rod 3, it will impact the fixed block 56 (the fixed block 56 will also break up the sewage), so that the fixed block 56 and the base 55 move downward, thereby driving the shielding ring 53 to move downward (using the valve 7 between the regulating tank 11 and the mixing tank 12 to control the sewage flow, or setting a plurality of connecting rods 54, and selecting elastic members 6 with suitable elasticity to ensure smooth completion of the action), the sewage treatment agent is rotated and sprayed into the mixing tank 12 from the discharge hole, and the sewage treatment agent and the sewage are fully mixed during the discharge process (since the amount of sewage is much greater than the amount of the sewage treatment agent, the sewage treatment agent will be added before the sewage is discharged, and the addition speed of the sewage treatment agent can be controlled by adjusting the specifications of the discharge hole), and the valve 7 may not be set on the discharge port 121, so that the sewage after mixing directly enters the sedimentation tank to avoid the accumulation of precipitation generated by the reaction on the inner wall of the mixing tank 12.
