[0021] Specifically, when using the wastewater treatment equipment for this farm: First, place the equipment base 1 in the designated location. Wastewater from the farm enters the first treatment tank 103 through the pipeline system. Because the wastewater contains large particles such as feces, it is drawn into the first treatment tank 103 by an external spiral pump. The coarse screen assembly 106 intercepts larger solids in the wastewater. Then, the controller 101 starts the water pump 11, and the pre-treated wastewater from the first treatment tank 103 enters the second treatment tank 104 through the water pump 11. The fine screen assembly 105 then treats smaller solids in the wastewater. Finally, the coarse screen assembly... The 106 and fine screen assembly 105 discharge solid matter from the wastewater into the collection frame 128. When solid matter enters the collection frame 128, it is blocked by the baffle plate 130. Subsequently, the pump body 11 controls the lift pump 119 to operate, and the lift pump 119 introduces the treated wastewater from the second treatment tank 104 into the grit chamber 117. The controller 101 controls the impeller assembly 107 to operate. When the impeller assembly 107 rotates, it can form an axial vortex inside the grit chamber 117, which reduces the flow rate of the wastewater. Heavier inorganic particles in the wastewater will settle to the bottom of the grit chamber 117. The controller 101 controls the solenoid valve on the surface of the discharge assembly 118 to open, so that the sand and particles settled at the bottom of the grit chamber 117 can be discharged. The particles are discharged from the grit chamber 117 through the discharge assembly 118. Subsequently, the controller 101 controls the first sewage pump 108 to operate, which introduces the sewage from the grit chamber 117 into the sedimentation tank 116 for sedimentation. During sedimentation, flocculant is added to the sewage in the sedimentation tank 116 through the feed cylinder 13 to accelerate the coagulation and sedimentation of small particles in the sewage, thereby improving the treatment efficiency of the sedimentation tank 116. The suspended solids in the sewage settle under gravity to form sludge. The controller 101 controls the valve on the surface of the effluent pipe 12 to open, and the supernatant in the sedimentation tank 116 enters the reaction tank 115 through the effluent pipe 12. An activated sludge mixture containing a large number of microorganisms is injected into the reaction tank 115 through the feed pipe 126. External aeration equipment introduces air into the reaction tank 115 through the air inlet pipe 125 to provide oxygen needed by the microorganisms inside the reaction tank 115, allowing the microorganisms and organic matter in the sewage to come into full contact. The microorganisms grow and reproduce by decomposing and absorbing organic matter, thereby removing organic matter from the sewage. Subsequently, the controller 101 controls the third sewage pump 120 to start, and the treated supernatant inside the reaction tank 115 enters the interior of the reaction tank 109 through the suction pipe 121 and the guide pipe 122. The user adds disinfectant to the interior of the reaction tank 109 through the feed cylinder 110 to disinfect the supernatant inside the reaction tank 109 and kill pathogenic microorganisms in the supernatant. Subsequently, the controller 101 controls the second sewage pump 113 to operate.The second sewage pump 113 draws out the supernatant after disinfection from the water storage chamber 114 and introduces it into the treatment tank 112. The supernatant is filtered by the filter screen 123 and the organic matter and odor in the supernatant are adsorbed and removed by the activated carbon screen 111. The controller 101 controls the valve on the surface of the sewage pipe 124 to open. The sludge generated during the sewage treatment process is discharged into the sedimentation tank 116 and the reaction tank 115 through the sewage pipe 124. Subsequently, the controller 101 controls the fourth sewage pump 127 to work. Under the action of the fourth sewage pump 127, the water treated in the treatment tank 112 is discharged into the natural water body. The specific structure and working principle of the fine screen assembly 105, coarse screen assembly 106, and impeller assembly 107 are existing technologies. The controller 101 controls the drive devices of the fine screen assembly 105, coarse screen assembly 106, and impeller assembly 107; the specific connection and control method is existing technology and will not be described further. The discharge assembly 118 consists of pipes and solenoid valves; the controller 101 controls the solenoid valves; the specific connection and control method is existing technology and will not be described further. The water storage chamber 114 is connected to the interior of the reaction tank 109 through a through-hole, allowing wastewater to flow smoothly into the water storage chamber 114.

[0022] Subsequently, when solid particles such as feces in the sewage enter the collection frame 128, the controller 101 controls the servo motor 21 inside the fixing frame 23 to work. Under the action of the servo motor 21, the rotating shaft 22 is driven to rotate. When the rotating shaft 22 rotates, it drives the adjusting screw 24 to rotate on the inner wall of the fixing frame 23. When the fixing frame 23 rotates, the adjusting screw 25 moves inside the fixing frame 23 due to the threaded engagement between the fixing frame 23 and the adjusting screw cylinder 25. When the adjusting screw cylinder 25 moves, it drives the scraper 26 to move within the collection frame 128. The internal reciprocating motion of the scraper 26 scrapes the solid particles inside the collection frame 128 out through the discharge port 129. The scraped solid particles are collected by an external transfer device. After dewatering, the water content of the solid particles and sludge is reduced. The dewatered solid particles and sludge can be incinerated or reused to realize the waste recycling function of the sewage treatment equipment. This maximizes the utilization of resources when the sewage treatment equipment is used and reduces the pollution of the soil and environment by sewage.

[0023] Subsequently, after the supernatant enters the interior of the reaction tank 109, the disinfectant enters the interior of the reaction tank 109 through the feed cylinder 110. The controller 101 controls the drive motor 31 inside the motor housing 32 to operate. Under the action of the drive motor 31, the shaft 33 rotates. When the shaft 33 rotates, it drives the stirrer 34 to rotate inside the reaction tank 109. Under the action of the stirrer 34, the disinfectant and supernatant inside the reaction tank 109 are mixed and stirred, so that the disinfectant and supernatant can react quickly and fully, avoiding... If the wastewater is not disinfected sufficiently, the supernatant inside the reaction tank 109 will flow into the storage chamber 114 under the action of gravity. However, during the flow of the supernatant, the stirrer 34 will stir the supernatant and the chemical solution, so that after the wastewater and the chemical react, the supernatant entering the storage chamber 114 can also be disinfected. This achieves the function of full reaction of the wastewater treatment equipment, thereby ensuring the uniformity of the mixing of the disinfectant and the supernatant when the wastewater treatment equipment is used. At the same time, it can improve the working efficiency and effect of the wastewater treatment equipment.

[0024] Subsequently, after prolonged use, the filter screen 123 is prone to clogging, affecting the flow efficiency of wastewater. The user pulls the baffle on the surface of the treatment box 112 to remove it, then pulls the filter screen 123 inside the treatment box 112. This causes the filter screen 123 to slide along the guide block 42 on the inner wall of the L-shaped frame 41. The guide block 42 guides the filter screen 123, causing the filter screen 123 to rotate along the inner wall of the L-shaped frame 41. The ball bearings 45 make it easier to remove and place the filter screen 123. After the filter screen 123 is pulled out, the locking block 44 moves away from the filter. The surface of the filter screen 123, under the action of the baffle 46, can block impurities during filtration, preventing them from entering the interior of the L-shaped frame 41 and affecting the pulling operation of the filter screen 123. When the cleaned filter screen 123 is reset, the locking block 44 on the surface of the fixing plate 43 automatically locks onto the surface of the filter screen 123, fixing the position of the filter screen 123. This enables the sewage treatment equipment to easily clean the filter screen 123, thus preventing clogging of the surface of the filter screen 123 during use. At the same time, it further improves the sewage treatment efficiency of the sewage treatment equipment and extends its service life. The controller 101 controls the valves on the surface of the water pump body 11, the first sewage pump 108, the second sewage pump 113, the outlet pipe 12 and the sewage pipe 124, the lift pump 119, the third sewage pump 120, the fourth sewage pump 127, the servo motor 21 and the drive motor 31. The specific connection and control methods are existing technologies and will not be described in detail here. Finally, the sewage treatment equipment is put into use.
