[0002] In actual industrial water pollution treatment, in order to ensure the effectiveness of environmental protection, it is usually necessary to purify industrial wastewater to facilitate subsequent reuse and achieve the purpose of water conservation. With the advancement of wastewater treatment technology, multi-stage wastewater treatment technology has been promoted, which can comprehensively treat wastewater through multi-stage wastewater treatment equipment.

The main pipe 103 has three rows of ventilation branch pipes 201 fixedly installed at its bottom, and each of the three rows of ventilation branch pipes 201 has an aeration pipe at its bottom; each of the three rows of ventilation branch pipes 201 has a shut-off solenoid valve 202 fixedly installed on its bottom; each of the three rows of ventilation branch pipes 201 has a pressure relief solenoid valve 203 fixedly installed on its bottom; the pressure relief solenoid valve 203 is used for pressure relief; each of the three rows of ventilation branch pipes 201 has a partition plate 204 fixedly installed on its bottom; the suspended solids separation device 3 includes: a separation slider 301, an installation pipe 302, and a suction pump. The suction pipe 3021 and the suction shell 303, and the separation slider 301 are slidably installed on the main body 101 of the water tank; the separation slider 301 is threadedly connected to the drive screw 104; a row of installation pipes 302 are fixedly installed on the separation slider 301; a suction pipe 3021 is fixedly installed at the top of the row of installation pipes 302, and the suction pipe 3021 is a blind pipe; the suction pipe 3021 is externally connected to a negative pressure fan; a suction shell 303 is fixedly installed at the bottom of the row of installation pipes 302 respectively; the row of suction shells 303 are slidably attached to the sides of the three partition plates 204 respectively; the suction shell 303 is used to separate suspended foam impurities; the aeration device 2 can perform real-time aeration treatment of sewage, which can not only ensure the sewage treatment effect, but also promote the mixing of wastewater; the through groove on the filter plate 102 can filter and block impurities, and in conjunction with the suspended solids separation device 3, the negative pressure suction separation method can effectively promote the negative pressure suction separation of surface suspended impurities, and prevent floating impurities and foam from affecting the sewage treatment quality.

[0021] The suspended solids separation device 3 further includes: a squeezing block 304, which is bolted to the side of the separation slider 301; the bottom of the squeezing block 304 has inclined surfaces on both sides; the control unit 4 includes: a control mounting plate 401 and control switches 402, which are bolted to the side of the water tank body 101; a row of control switches 402 are fixedly mounted on the control mounting plate 401, and each row of control switches 402 is electrically connected to three air-closing solenoid valves 202 and pressure-relief solenoid valves 203 on the same side; the squeezing block 304 is aligned with the row of control switches 402; by using the suspended solids separation device 3 in conjunction with the control unit 4, when the suction shell 303 is displaced to suck up floating impurities, the ventilation branch pipe 201 at the suspended solids separation device 3 can be automatically closed to prevent excessive turbulence of the liquid surface when the ventilation branch pipe 201 at the position of sucking up suspended impurities continues to emit air for aeration, which would affect the impurity loading. The pressure suction separation is comprehensive, and a large number of impurities will be stirred up below the sewage surface. This structure can improve the quality of suspended solids suction separation, while not affecting the normal exhaust and aeration work of the other venting branch pipes 201, reducing the impact on aeration efficiency. The pressure relief solenoid valve 203 can be used to relieve pressure, avoiding the closure of the local air-closing solenoid valve 202, which would cause excessive pressure rise in the other venting branch pipes 201 and damage to the aeration pipes. The structure is simple to control and improves the quality of suspended solids suction separation. When the separation slider 301 moves, it drives the squeezing block 304 to move synchronously. The inclined structure at the bottom of the squeezing block 304 squeezes the control switch 402, which in turn controls the three air-closing solenoid valves 202 on the same side of the suction shell 303 to close and the pressure relief solenoid valve 203 to open, realizing pipeline pressure relief. At this time, the liquid surface at the suction shell 303 stops churning, which facilitates the floating of impurities and improves foam stability, which is conducive to negative pressure suction separation.

[0022] The secondary conditioning component 5 includes: a secondary conditioning tank 501, a stop bar 5011, and a discharge pipe 5012. The secondary conditioning tank 501 is fixedly installed on the main body 101 of the water tank. The stop bar 5011 is fixedly installed inside the secondary conditioning tank 501. The discharge pipe 5012 is fixedly installed at the bottom of the secondary conditioning tank 501, and a valve is provided on the discharge pipe 5012. The secondary conditioning component 5 also includes: a conveyor motor 502, a drive roller 503, a conveyor belt 5031, and a stop plate 504. The conveyor motor 502 is fixedly installed on the secondary conditioning tank 501. The output shaft of the conveyor motor 502 passes through the secondary conditioning tank 501. Two drive rollers 503 are rotatably installed inside the secondary conditioning tank 501. A conveyor belt 5031 is driven onto roller 503, and the outer side of the conveyor belt 5031 is attached to stop strip 5011; stop plate 504 is fixedly installed inside the secondary conditioning tank 501; both sides of the conveyor belt 5031 are slidably attached to the inner side of the secondary conditioning tank 501; stop plate 504 is located inside the conveyor belt 5031; the tertiary isolation component 6 includes: a propulsion hydraulic cylinder 601, three propulsion hydraulic cylinders 601 are fixedly installed on the secondary conditioning tank 501, and the output shafts of the three propulsion hydraulic cylinders 601 pass through the secondary conditioning tank 501 respectively; the tertiary isolation component 6 also includes: a stop block 602, the stop block 602 is slidably inserted into the inner side of the secondary conditioning tank 501; the stop block 602 is used to attach to the conveyor belt 5031. Stop blocks 602 are fixedly installed on the output shafts of the three propulsion hydraulic cylinders 601; the three-stage isolation component 6 can be used in conjunction with the two-stage conditioning component 5 to facilitate secondary conditioning and flocculation sedimentation work by the staff. The operation is simple. With the help of the conveyor belt 5031, it is easy for the staff to control and isolate the sludge before conditioning and flocculation, so as to prevent the sludge deposited at the bottom of the sewage from churning during subsequent conditioning and stirring work, which would interfere with flocculation and affect the conditioning quality. The structure is simple to control; the sewage after aeration overflows from one side of the main body of the pool 101 into the secondary conditioning tank 501. At this time, as the overflow time increases, a large amount of sludge will be deposited on the conveyor belt 5031. At this time, the conveyor belt can be controlled. Machine 502 drives the drive roller 503 on the same side to rotate, thereby driving the conveyor belt 5031 to run slowly. The sludge deposited on the top of the conveyor belt 5031 is slowly transported to the bottom of the secondary conditioning tank 501. This structure is suitable for sewage treatment scenarios with high sludge content. During the conveying process of the conveyor belt 5031, the stop bar 5011 can scrape and clean the sludge on the surface of the conveyor belt 5031. After the conveyor belt 5031 transports the sludge to the bottom of the main body of the tank 101, the stop block 602 can be moved by the push hydraulic cylinder 601. The stop is tightly attached to the side of the conveyor belt 5031 to perform isolation work. Under the cover of the conveyor belt 5031, the sludge below the conveyor belt 5031 will not be mixed and stirred up together.

[0023] Working principle: First, wastewater is introduced into the main body 101 of the pool. An external blower supplies air through the main pipe 103. The gas is discharged from the aeration pipe at the bottom through three rows of ventilation branch pipes 201, completing wastewater aeration. During this process, foam and floating impurities will float to the surface. The drive motor 105 controls the drive screw 104 to rotate, driving the separation slider 301 to move, which in turn moves the suction shell 303. Negative pressure suction and separation are achieved through a negative pressure blower connected to the suction pipe 3021, causing the suction shell 303 to move at the liquid surface. As the separation slider 301 moves, it also moves the squeezing block 304. By utilizing the inclined structure at the bottom of the squeezing block 304, the control switch 402 can be squeezed to close the three air-closing solenoid valves 202 on the same side of the suction shell 303 and open the pressure relief solenoid valve 203 to achieve pressure relief. At this time, the liquid surface at the suction shell 303 stops churning, which facilitates the floating of impurities and improves foam stability, making it easier for negative pressure suction and separation. During the movement of the separation slider 301, the squeezing block 304 can sequentially trigger the air-closing solenoid valves 202 near the suction shell 303 to complete the closing action. The wastewater after aeration overflows from one side of the main body of the pool 101. The sludge overflows into the secondary conditioning tank 501. As the overflow time increases, a large amount of sludge will accumulate on the conveyor belt 5031. At this point, the conveyor motor 502 can be controlled to drive the drive roller 503 on the same side to rotate, thereby driving the conveyor belt 5031 to run slowly and slowly transport the sludge deposited on the top of the conveyor belt 5031 to the bottom of the secondary conditioning tank 501. This structure is suitable for wastewater treatment scenarios with high sludge content. After the conveyor belt 5031 transports the sludge to the bottom of the secondary conditioning tank 501, the stop block 602 is moved by the hydraulic cylinder 601, causing the stop to... Block 602 is attached to the side of conveyor belt 5031 to isolate sludge. Subsequently, staff can directly condition and flocculate the wastewater in the secondary conditioning tank 501. At this time, the sludge content is relatively low, which can reduce the amount of flocculant used. At the same time, a wastewater agitator can be installed on the secondary conditioning tank 501 to promote the mixing of the agents. During this process, under the shielding effect of conveyor belt 5031, the sludge below it will not be agitated due to mixing and stirring, thus preventing the turbidity of the wastewater from increasing further. The deposited sludge can be discharged by opening the valve on the discharge pipe 5012.
