[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. After the external water pipe is connected to the water inlet in this solution, the impact of the water flow will drive the fan blades to rotate. The rotation of the fan blades drives the rotation of the first rotating column, and the first rotating column drives the rotation of one of the first sprockets. Through linkage, the slide plate, the C-shaped frame, and the first spring can be driven to move downward, which can scrape the surface of the filter screen to prevent debris from blocking the filter screen. Then, continuous downward movement causes the C-shaped frame to contact the pressing plate, squeezing the second spring, so that the pressing plate drives the first rack to move downward, and through linkage, the debris can be collected into the recycling box. Then, through the chute on the surface of the screw rod, the slide plate can be driven to move upward, while closing the first sealing plate, and the excess water can be squeezed out by squeezing the debris with the squeezing block;

[0017] 2. By starting the first water pump in this solution, the treated water source in the filtration chamber can be pumped into the sedimentation chamber for treatment. Then, the corresponding motor is started, and the output shaft of the motor drives the rotation of the first rotating shaft. Through linkage, the sewage and the flocculant can be evenly stirred and mixed, and then sedimentation is carried out. After sedimentation is completed, the valve two is opened to allow the water source to enter the treatment chamber, and the water source is treated by the activated carbon adsorption net. Then, the second water pump is started, and the treated water source in the treatment chamber can be pumped into the disinfection chamber. Then, the corresponding motor is started, and the disinfectant in the second storage tank can be evenly discharged through linkage. At the same time, through linkage, the sewage and the disinfectant can be evenly stirred and mixed;

[0018] 3. By opening the fourth sealing plate in this solution, the water source can enter the lower water chamber, and then the water quality of the water source is detected by the water quality detection sensor. When the water quality of the water source does not meet the standard, the hydraulic cylinder is started, and the hydraulic cylinder drives the second sealing plate to move downward. Through linkage, the treated water source in the treatment chamber can be pumped into the disinfection chamber for cyclic filtration treatment until the water source meets the standard;

[0019] 4. By starting the hydraulic cylinder in this solution, the second sealing plate moves downward. Through linkage, the third sealing plate can be moved to one side for closing. Then, the rotation of the fourth rotating shaft drives the rotation of one of the fifth sprockets, and through linkage, the water source can be discharged through the drain pipe.

[0020] The present invention can thoroughly treat sewage and can detect whether the sewage meets the discharge standard, improving the protection of the ecology. BRIEF DESCRIPTION OF THE DRAWINGS

Then, continue to move downward so that the C-shaped frame 16 contacts the pressing plate 21, compresses the second spring 22, so that the pressing plate 21 drives the first rack 23 to move downward. The first rack 23 drives the first gear 24 to rotate. The first gear 24 drives the first rotating column 25 to rotate. The first rotating column 25 drives one of the second sprockets 31 to rotate. One of the second sprockets 31 drives the other second sprocket 31 to rotate through the second chain 32, so that the third rotating column 29 drives the extrusion block to recover. Then, the first rack 23 continues to move downward, drives the second gear 26 to rotate. The second gear 26 drives the second rotating column 27 to rotate. The second rotating column 27 drives one of the third sprockets 33 to rotate. One of the third sprockets 33 drives the other third sprocket 33 to rotate through the fourth chain 35, which can drive the first sealing plate 19 to rotate and open. At this time, the C-shaped frame 16 cannot continue to move downward. The sliding plate 15 can continue to move downward by squeezing the first spring 17, collect the debris into the recovery box 18, and then drive the sliding plate 15 to move upward through the chute on the surface of the screw 5, while closing the first sealing plate 19, and squeeze the debris through the extrusion block to squeeze out the excess water;

[0055] By starting the first water pump, the treated water source in the filtration chamber 3 can be pumped into the sedimentation chamber 38 for treatment. Then, start the corresponding motor 41. The output shaft of the motor 41 drives the first rotating shaft 42 to rotate. The first rotating shaft 42 drives the fourth bevel gear 43 to rotate. The fourth bevel gear 43 drives the fifth bevel gear 44 to rotate. The fifth bevel gear 44 drives the second rotating shaft 45 to rotate. The second rotating shaft 45 drives the conveying auger 46 to rotate, so as to evenly discharge the flocculant in the first storage tank 36. At the same time, the first rotating shaft 42 drives one of the fourth sprockets 47 to rotate. One of the fourth sprockets 47 drives the other fourth sprocket 47 to rotate through the third chain, so that the third rotating shaft 48 drives the sixth bevel gear 49 to rotate. The sixth bevel gear 49 drives the seventh bevel gear 50 to rotate. The seventh bevel gear 50 drives the second rotating column to rotate. The second rotating column drives the mixing rod 53 to rotate, so as to evenly stir and mix the sewage and the flocculant. Then, sedimentation is carried out. After the sedimentation is completed, open the second valve 8 to make the water source enter the treatment chamber 78. The water source is treated by the activated carbon adsorption net 79. Then, start the second water pump, and the treated water source in the treatment chamber 78 can be pumped into the disinfection chamber 39. Then, start the corresponding motor 41. Through the above linkage, the disinfectant in the second storage tank 37 can be evenly discharged. At the same time, through the linkage, the sewage and the disinfectant can be evenly stirred and mixed;

[0056] Open the fourth sealing plate 65, and the water source can enter the lower water chamber 55. Then, the water quality of the water source is detected by the water quality detection sensor 54. When the water quality of the water source does not meet the standard, start the hydraulic cylinder 56. The hydraulic cylinder 56 drives the second sealing plate 57 to move downward, and at the same time drives the third rack 58 to move downward, driving the third gear 59 to rotate. The third gear 59 drives the fourth rotating shaft 60 to rotate. The fourth rotating shaft 60 drives one of the sixth sprockets 73 to rotate. One of the sixth sprockets 73 drives the other sixth sprocket 73 to rotate through the sixth chain 74. The other sixth sprocket 73 drives the first rotating rod 64 to rotate, so that the first rotating rod 64 drives the fourth gear 63 to rotate. The fourth gear 63 drives the fourth rack 62 to move to one side, and then drives the third sealing plate 61 to move to one side, so that the water source enters the treatment chamber 78. Then, by starting the second water pump, the treated water source in the treatment chamber 78 can be pumped into the disinfection chamber 39 for cyclic filtration treatment until the water source meets the standard;

[0057] When the water source meets the standard, by starting the hydraulic cylinder 56, the hydraulic cylinder 56 drives the second sealing plate 57 to move downward. Through the above linkage, the third sealing plate 61 can be moved to one side to be closed. Then, the fourth rotating shaft 60 rotates to drive one of the fifth sprockets 71 to rotate. One of the fifth sprockets 71 drives the other fifth sprocket 71 to rotate through the fifth chain 72, so that the second rotating rod 70 drives the fifth gear 69 to rotate, and then drives the fifth rack 68 to move downward and drives the fifth sealing plate 67 to move upward. Then, open the first valve 66, and the water source can be discharged through the drain pipe 76.
