[0035] The working principle of the above embodiment is:

[0036] (1) When it is necessary to mix the wastewater and the purified liquid, the first motor 202 is started, and the first motor 202 drives the first rotating rod 203 and the first gear 204 to rotate together, and drives the second gear 208 and the third rotating rod 207 to rotate together through the first gear 204, and drives the first pulley to rotate through the first rotating rod 203, and the first pulley drives the second pulley and the second rotating rod 206 to rotate together through the belt, and drives the first rotating rod 203 and the second rotating rod 206 to rotate simultaneously, and drives the first bevel gear 210 to rotate, and drives the second bevel gear 211 and the fourth rotating rod 212 to rotate together through the first bevel gear 210, and drives the connecting plate 213 and the first stirring rod 214 to rotate together through the fourth rotating rod 212, and drives the plurality of second stirring rods 215 to rotate together through the first rotating rod 203, the second rotating rod 206 and the third rotating rod 207, so as to mix the wastewater and the purified liquid, facilitate the reuse of the wastewater, improve the utilization rate, and facilitate the treatment of the waste gas.
