[0032] The bottom of both the fourth fixed plate 9 and the fifth fixed plate 10 are fixedly connected with two limiting rods 29. The top of both the first lifting plate 27 and the second lifting plate 28 are provided with through holes 30.

In addition, the circumferential surfaces of the first lifting plate 27 and the second lifting plate 28 are provided with sealing gaskets, which can prevent wastewater leakage.

[0033] Each of the three storage plates 32 is equipped with a sealing gasket between itself and the outer casing 1, which improves the overall sealing performance of the device.

[0034] Working Principle: During operation, wastewater is first poured into the leftmost chamber of the outer casing 1. Then, chemical powder reagents MgCl2·6H2O and Na2HPO4·12H2O are poured into the highest chamber on the left. Powdered activated carbon is poured into the middle chamber, and two sections of activated sludge are poured into the lowest chamber on the right. Then, the servo motor 3 is electrically activated, driving the first rotating shaft 5 to rotate forward. The first rotating shaft 5 drives the first sprocket 16 to rotate, which in turn drives the first chain 22. The first chain 22 drives the second sprocket 17 and the fifth sprocket 20 to rotate. The second sprocket 17 drives the second rotating shaft 11 to rotate, which in turn drives the stirring rod 25 to rotate. The stirring rod 25 then rotates the left... The wastewater in the side chamber reacts chemically with the powdered reagents MgCl2·6H2O and Na2HPO4·12H2O, achieving preliminary filtration of the wastewater. The precipitate from the reaction settles downwards into the collection hole 33 on the collection plate 32. The fifth sprocket 20 drives the first threaded rod 14 to rotate, which in turn drives the first lifting plate 27 to slide upwards, allowing the wastewater from the left side chamber to be discharged into the middle chamber. The fifth sprocket 20 then drives the second chain 23, which in turn drives the third sprocket 18 and the sixth sprocket 21 to rotate. The third sprocket 18 drives the third rotating shaft 12 to rotate, which in turn drives the stirring rod 25 to rotate. The stirring rod 25 then rotates the stirring rod in the middle chamber. The wastewater in the intermediate chamber is mixed with powdered activated carbon to achieve secondary reaction filtration of the wastewater. The precipitate from the reaction settles downward into the collection hole 33 on the collection plate 32. The sixth sprocket 21 drives the second threaded rod 15 to rotate, which in turn drives the second lifting plate 28 to slide upward, allowing the wastewater from the intermediate chamber to flow into the right chamber. Then, the sixth sprocket 21 drives the third chain 24, which in turn drives the fourth sprocket 19 to rotate. The fourth sprocket 19 drives the fourth rotating shaft 13 to rotate, which in turn drives the stirring rod 25 to rotate. The stirring rod 25 then reacts with the wastewater and the two sections of activated sludge in the right chamber, and the precipitate from the reaction settles downward into the collection plate 32. Inside the receiving hole 33, the wastewater that has completed the reaction in the right chamber will be discharged from the outlet 31. When the first lifting plate 27 and the second lifting plate 28 slide to the top, the servo motor 3 can be started through electrical connection to drive the first rotating shaft 5 to rotate in the opposite direction, thereby driving the above-mentioned device to rotate in the opposite direction, thus realizing the reverse rotation of the stirring rod 25. This enables better fusion reaction of wastewater and reactants in each chamber, and also drives the first lifting plate 27 and the second lifting plate 28 to slide downward, thus blocking the three chambers. When the bottom of the first lifting plate 27 and the second lifting plate 28 are in contact with the top of the partition 26, the servo motor 3 can be started again to drive the first rotating shaft 5 to rotate in the forward direction. This process is repeated to achieve multi-stage reaction filtration of wastewater.
