Wherein, according to the picture includes the following steps:

s1, introducing the sewage into the sewage treatment tank 1, screening the sewage by the purification unit 104, and introducing the sewage into the sewage collection tank 2 through the sewage discharge pipe 103.

S2: the sewage after being screened is guided into the anaerobic tank 3 through the water outlet pipe 102 to release phosphorus for ammoniation, the sewage is guided into the anoxic tank 4 again through the water outlet pipe 102 after the treatment is finished, and the treated sewage enters the sewage collecting tank 2 through the feedback pipeline 7.

S3: the treated water enters the anoxic tank 4 for denitrification treatment, the sewage is guided into the aerobic tank 5 again through the water outlet pipe 102 after the treatment is finished, and simultaneously the treated sewage enters the sewage collecting tank 2 through the feedback pipeline 7.

S4: the treated water enters the aerobic tank 4 for nitrification, phosphorus absorption and BOD removal, the sewage is guided into the sedimentation tank 6 again through the water outlet pipe 102 after the treatment is finished, and the treated sewage enters the sewage collecting tank 2 through the feedback pipeline 7.

S5: the treated water enters the sedimentation tank 6 for sedimentation, the settled treated water can be discharged for use, and simultaneously, the sewage settled at the bottom of the sedimentation tank 6 enters the sewage collection tank 2 through the feedback pipeline 7.

The working principle is as follows: the purification unit 104 is inserted into the sealing sliding groove 106 through the installation hole 105 for the first phase, and when the biological sewage enters the inside of the sewage treatment tank 1 through the sewage pipe 101, the biological sewage is purified by passing through the third purification unit 104 in sequence.

When the sewage passes through the purifying unit 104, the filtering components 109 inside the purifying unit are filtered by the filtering nets 112 on both sides, and the water flow drives the driving disc 114 to rotate, so that the rotating shaft 113 drives the transmission shaft 116 to rotate, and the screw 117 in the chute 110 of the cleaning component rotates to drive the cleaning component 111 to move.

When the screw 117 rotates, the cleaning assembly 111 will move up and down along the cleaning assembly sliding slot 110, and the cleaning layer 118 cleans the surface of the filter screen 112 and guides the dirt into the cleaning assembly 111, the driving guide wheel 119 will engage with the filter screen 112 during the movement of the cleaning assembly 111 to provide power for the hydraulic assembly 127, when the cleaning assembly 111 moves to the top of the cleaning assembly sliding slot 110, the driving screw 122 at the top of the limit block 120 will contact with the cleaning assembly sliding slot 110 and move downwards, so that the engaging screw 125 inside the limit block 120 is driven to rotate to drive the engaging block 124 to move towards the engaging block sliding slot 123 at one side of the limit block 120 and engage with the screw 117 in one side of the cleaning assembly sliding slot 110, so that the cleaning assembly 111 moves downwards along the cleaning assembly sliding slot 110, and when reaching the bottom, the cleaning assembly will move in the opposite direction according to the above manner.

When the driving guide wheel 119 rotates, the driving guide wheel 136 drives the driving post 136 engaged with the driving guide wheel to rotate, so that the driving post 136 drives the screw rods 137 at both sides to rotate, meanwhile, the oil pressing plate 138 engaged with the screw rods 137 extrudes hydraulic oil into the hydraulic telescopic pump 132 through the oil pipe 131, when the hydraulic oil enters the oil chamber 140 through the oil pipe 131 and the built-in oil pipe 139, the extrusion telescopic rod 141 sequentially extends out of the hydraulic telescopic pump 132, when the telescopic rod 141 sleeved at the innermost layer reaches the top end, the trigger screw 155 in the device chamber 145 in the inner wall of the trigger movable groove 154 moves towards the inside of the device chamber 145, the cable post 147 at one side of the driving device chamber 145 rotates, and the cable post 147 at the other side of the device chamber 145 rotates through the cable 146, the cable post 147 at the other side drives the bolt driving post 151 to rotate, and at this time, the bolt 152 wound on the bolt driving post 151 contracts to pull the bolt 150 into the lock post 149, make the telescopic link 141 contact locking of next layer, make telescopic link 141 stretch out hydraulic telescoping pump 132 in proper order, and make push pedal 135 promote the inside filth of collecting of clean subassembly to the center, utilize the angle of inclination of push pedal 135 to make the filth pass through check valve 129 and get into drain 108 simultaneously, treat when clean subassembly 111 reachs clean subassembly spout 110 top when drain 108 and blow off pipe 103 switch on with the filth collect in leading-in filth collecting box 2 of blow off pipe 103.

After sewage enters the sewage treatment tank 1 for purification, the sewage is guided into the anaerobic tank 3 through the water outlet pipe 102 for phosphorus release and ammoniation, after treatment, the sewage is guided into the anoxic tank 4 through the water outlet pipe 102, treated water enters the anoxic tank 4 for denitrification treatment, after treatment, the sewage is guided into the aerobic tank 5 through the water outlet pipe 102, the treated water enters the aerobic tank 4 for nitrification, phosphorus absorption and BOD removal, after treatment, the sewage is guided into the sedimentation tank 6 through the water outlet pipe 102 for sedimentation, the water source after sedimentation can be reused, meanwhile, the bottoms of the anoxic tank 4, the aerobic tank 5 and the sedimentation tank 6 are respectively provided with a feedback pipeline 7 communicated with the sewage collection tank 2, and sewage generated in the further treatment process can be guided into the sewage collection tank 2 through the feedback pipeline 7 for storage.
