[0025] Example 1

[0026] Please see Figure 1-6 A high-efficiency wastewater ammonia and phosphorus removal device includes a pretreatment component 1, a purification component 2, and a deep removal component 3. The pretreatment component 1, purification component 2, and deep removal component 3 are connected sequentially along the wastewater flow direction and treat the wastewater in sequence. The pretreatment component 1 is used to filter solid impurities in the wastewater, the purification component 2 is used to remove ammonia and phosphorus from the wastewater through biological purification, and the deep removal component 3 is used to perform deep phosphorus removal from the wastewater through chemical purification.

[0027] Pretreatment component 1 includes a pretreatment box 101, an inlet 102, a first filter frame 103, a second filter frame 104, a first filter screen 105, a second filter screen 106, a collection box 107, and a collection port 108. The pretreatment box 101 has an inlet 102 on its top surface. The collection box 107 is fixedly connected to one side of the interior of the pretreatment box 101, and the first filter frame 103 and the second filter frame 104 are fixedly connected to the other side. The first filter frame 103 is located above the second filter frame 104. A filter screen 105 is fixedly connected inside a filter frame 103, and a filter screen 106 is fixedly connected inside a filter frame 104. The mesh size of the filter screen 105 is smaller than that of the filter screen 106. The other ends of the filter frames 103 and 104 are fixedly connected to the pretreatment box 101. The impurity collection box 107 has two sets of impurity collection ports 108 on the side connected to the filter frames 103 and 104, which correspond to the filter frames 103 and 104 respectively.

[0028] Pretreatment component 1 also includes an anti-clogging motor 109, a drive wheel 110, a transmission wheel 111, a transmission belt 112, an anti-clogging screw 113, an anti-clogging screw block 114, an anti-clogging brush 115, and an anti-clogging gear 116. The anti-clogging motor 109 is fixedly connected to the top surface of the pretreatment box 101, and the output shaft of the anti-clogging motor 109 is fixedly connected to the drive wheel 110. Two sets of anti-clogging screws 113 are rotatably connected to the side of the collection box 107. The anti-clogging screws 113 are respectively located above filter frame one 103 and filter frame two 104. The other end of each of the three parts passes through the pretreatment box 101 and is fixedly connected to an anti-clogging gear 116. The two sets of anti-clogging gears 116 mesh with each other. The front end of one set of anti-clogging screw blocks 114 is fixedly connected to a transmission wheel 111. The drive wheel 110 and the transmission wheel 111 are connected by a transmission belt 112. Anti-clogging screw blocks 114 are threadedly connected to each anti-clogging screw 113. Anti-clogging brushes 115 are fixedly connected to the bottom surface of the anti-clogging screw blocks 114. The bristles of the two sets of anti-clogging brushes 115 abut against the surfaces of filter screen one 105 and filter screen two 106, respectively.

[0029] Wastewater first enters the pretreatment tank 101 through inlet 102. Under the influence of gravity, the wastewater flows from top to bottom, first passing through filter screen 105 in filter frame 103, where larger solid particles are intercepted. The wastewater then continues to flow downwards, passing through filter screen 106 in filter frame 204, where smaller solid particles are intercepted. During filtration, the anti-clogging motor 109 starts, driving the drive wheel 110 to rotate. The drive wheel 110 drives the transmission wheel 111 to rotate via the transmission belt 112, which in turn causes the anti-clogging screw 113 connected to the transmission wheel 111 to rotate. Because the two sets of anti-clogging gears 116 mesh, the other set of anti-clogging screws 113 also rotates synchronously. When the anti-clogging screw 113 rotates, the anti-clogging screw block 114 moves along the screw under the action of the thread, driving the anti-clogging brush 115 to move back and forth on the surface of filter screen 105 and filter screen 2 106, brushing the impurities on the filter screen from the impurity collection port 108 into the impurity collection box 107, preventing the filter screen from clogging and ensuring the continuous and efficient operation of the pretreatment component 1.

[0030] Example 2

[0031] This embodiment, based on Embodiment 1, adds the following improvements: The purification component 2 further includes an anaerobic chamber 201, an anoxic chamber 202, a first air pump 203, a second air pump 204, an oxygen sensor 205, an oxygen sensor 206, a first delivery pipe 207, a second delivery pipe 208, and a delivery valve 209. The anaerobic chamber 201 is fixedly connected to the bottom surface of the pretreatment chamber 101, and the anoxic chamber 202 is fixedly connected to the bottom surface of the anaerobic chamber 201. The inlet of the first delivery pipe 207 extends into the lower part of the pretreatment chamber 101, and the outlet extends into the top surface of the anaerobic chamber 201.

[0033] Pretreated wastewater enters anaerobic tank 201 through conveyor pipe 207. Inside anaerobic tank 201, anaerobic microorganisms decompose organic matter in the wastewater under anaerobic conditions, while polyphosphate-accumulating bacteria release phosphorus. Oxygen sensor 205 monitors the oxygen content in anaerobic tank 201 in real time. When the oxygen content rises and affects the anaerobic environment, air pump 203 starts to expel excess oxygen from the tank, maintaining the anaerobic environment. After anaerobic treatment, the wastewater enters anoxic tank 202 through conveyor pipe 208. Inside anoxic tank 202, denitrifying bacteria use the organic matter in the wastewater as a carbon source to reduce nitrate nitrogen to nitrogen gas, achieving denitrification. Similarly, oxygen sensor 206 monitors the oxygen content in anoxic tank 202, and air pump 204 adjusts the oxygen content to maintain the anoxic environment. After anoxic treatment, the wastewater enters aerobic tank 210 through conveyor pump 211 and conveyor pipe 212. Inside the aerobic tank 210, aerobic microorganisms oxidize ammonia nitrogen in wastewater into nitrate nitrogen in an oxygen-rich environment, while polyphosphate-accumulating bacteria absorb excess phosphorus, thus achieving phosphorus removal. The oxygen pump 214 continuously supplies oxygen to the aerobic tank 210 to meet the growth needs of the aerobic microorganisms.

[0034] The deep cleaning component 3 includes a filter tank 215, a sliding groove 216, a sliding baffle 217, a filter screen 218, and a filter cylinder 219.

The front end of the piston rod of the filter cylinder 219 passes through the aerobic chamber 210 and is fixedly connected to the sliding baffle 217. The filter screen 218 is detachably connected in the filter tank 215 and is located below the sliding baffle 217.

[0035] The deep removal component 3 also includes a feed pipe 301, an outlet 302, a feed inlet 303, and a phosphorus removal agent hopper 304. The feed pipe 301 is fixedly connected to the side wall of the aerobic tank 210. One end of the feed pipe 301 extends into the aerobic tank 210, and the other end is located outside the aerobic tank 210. The feed inlet 303 is opened on the top surface of the feed pipe 301 outside the aerobic tank 210. The phosphorus removal agent hopper 304 is fixedly connected to the top surface of the feed pipe 301. The phosphorus removal agent hopper 304 is connected to the feed pipe 301 through the feed inlet 303. The outlet 302 is opened on the bottom surface of the feed pipe 301 inside the aerobic tank 210.

[0036] The deep cleaning component 3 also includes a feeding frame 305, a backing plate 306, a cylinder frame 307, and a feeding cylinder 308. The feeding frame is slidably connected inside the feeding pipe 301. The size of the feeding frame 305 is adapted to the inner diameter of the feeding pipe 301. The backing plate 306 is fixedly connected to the outside of the feeding frame. The top surface of the backing plate 306 is in movable contact with the inner top surface of the feeding pipe 301.

The front end of the piston rod of the feeding cylinder 308 is fixedly connected to the feeding frame 305.

[0037] After biological purification, the wastewater, along with the sediment, flows to the filter tank 215. When filtration is required, the filter cylinder 219 pushes the sliding baffle 217 to open, allowing the wastewater and sediment to pass through the filter screen 218 in the filter tank 215. The sediment is intercepted by the filter screen 218, and the biologically purified wastewater flows into the space below the baffle 213. The phosphorus removal agent enters the feed pipe 301 from the phosphorus removal agent hopper 304 through the feed inlet 303. The feeding cylinder 308 pushes the feeding frame 305 to slide within the feed pipe 301, quantitatively pushing the phosphorus removal agent to the discharge outlet 302. The phosphorus removal agent enters the aerobic tank 210 from the discharge outlet 302, where it reacts chemically with the phosphorus in the wastewater, achieving deep phosphorus removal and ensuring that the effluent quality meets standards.

[0038] Working principle

[0039] Wastewater first enters the pretreatment tank 101 through inlet 102. Under the influence of gravity, the wastewater flows from top to bottom, first passing through filter screen 105 in filter frame 103, where larger solid particles are intercepted. The wastewater then continues to flow downwards, passing through filter screen 106 in filter frame 204, where smaller solid particles are intercepted. During filtration, the anti-clogging motor 109 starts, driving the drive wheel 110 to rotate. The drive wheel 110 drives the transmission wheel 111 to rotate via the transmission belt 112, which in turn causes the anti-clogging screw 113 connected to the transmission wheel 111 to rotate. Because the two sets of anti-clogging gears 116 mesh, the other set of anti-clogging screws 113 also rotates synchronously. When the anti-clogging screw 113 rotates, the anti-clogging screw block 114 moves along the screw under the action of the thread, driving the anti-clogging brush 115 to move back and forth on the surface of filter screen 105 and filter screen 2 106, brushing the impurities on the filter screen from the impurity collection port 108 into the impurity collection box 107, preventing the filter screen from clogging and ensuring the continuous and efficient operation of the pretreatment component 1.

[0040] Pretreated wastewater enters anaerobic tank 201 through conveyor pipe 207. Inside anaerobic tank 201, anaerobic microorganisms decompose organic matter in the wastewater under anaerobic conditions, while polyphosphate-accumulating bacteria release phosphorus. Oxygen sensor 205 monitors the oxygen content in anaerobic tank 201 in real time. When the oxygen content rises and affects the anaerobic environment, air pump 203 starts to expel excess oxygen from the tank, maintaining the anaerobic environment. After anaerobic treatment, the wastewater enters anoxic tank 202 through conveyor pipe 208. Inside anoxic tank 202, denitrifying bacteria use the organic matter in the wastewater as a carbon source to reduce nitrate nitrogen to nitrogen gas, achieving denitrification. Similarly, oxygen sensor 206 monitors the oxygen content in anoxic tank 202, and air pump 204 adjusts the oxygen content to maintain the anoxic environment. After anoxic treatment, the wastewater enters aerobic tank 210 through conveyor pump 211 and conveyor pipe 212. Inside the aerobic tank 210, aerobic microorganisms oxidize ammonia nitrogen in wastewater into nitrate nitrogen in an oxygen-rich environment, while polyphosphate-accumulating bacteria absorb excess phosphorus, thus achieving phosphorus removal. The oxygen pump 214 continuously supplies oxygen to the aerobic tank 210 to meet the growth needs of the aerobic microorganisms.

[0041] After biological purification, the wastewater, along with the sediment, flows to the filter tank 215. When filtration is required, the filter cylinder 219 pushes the sliding baffle 217 to open, allowing the wastewater and sediment to pass through the filter screen 218 in the filter tank 215. The sediment is intercepted by the filter screen 218, and the biologically purified wastewater flows into the space below the baffle 213. The phosphorus removal agent enters the feed pipe 301 from the phosphorus removal agent hopper 304 through the feed inlet 303. The feeding cylinder 308 pushes the feeding frame 305 to slide within the feed pipe 301, quantitatively pushing the phosphorus removal agent to the discharge outlet 302. The phosphorus removal agent enters the aerobic tank 210 from the discharge outlet 302, where it reacts chemically with the phosphorus in the wastewater, achieving deep phosphorus removal and ensuring that the effluent quality meets standards.
