Technical Field
[0001] This invention relates to the field of wastewater treatment and environmental protection technology, specifically to a water treatment environmental protection process and method based on nano-microbubbles. Background Technology
[0002] Wastewater treatment is a crucial part of environmental governance. The purification and removal of impurities from water resources are related to people's daily lives, work, and production. With the advancement of technology, micro-nano bubble technology has begun to be applied to wastewater treatment. Micro-nano bubble technology introduces micro-nano bubbles into wastewater through a micro-nano bubble generator. The micro-nano bubbles carry impurities in the wastewater to the surface, thereby achieving the effect of removing impurities from the wastewater. However, most existing nano-bubble wastewater treatment methods treat solid pollutants and liquid wastewater together, and the purified water still contains solid pollutants after discharge. The purification efficiency is low, and the lack of stirring equipment makes the mixing of nano-microbubbles and wastewater uneven. Therefore, it is necessary to design an environmentally friendly water treatment process and method based on nano-microbubbles. Summary of the Invention
[0003] The purpose of this invention is to provide an environmentally friendly water treatment process and method based on nano-microbubbles to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a water treatment environmental protection process and method based on nano-microbubbles, comprising a wastewater purification equipment body, a nano-microbubble generator, an air guide pipe, a motor, a fixing plate, and a protective shell. A rotating rod is fixedly installed at the output end of the motor and rotatably connected to one side of the fixing plate. A stirring paddle is fixedly connected to the outer side of the rotating rod. A solid pollutant collection box is slidably installed on the other side of the wastewater purification equipment body. A filter screen is slidably installed through the other side of the top of the wastewater purification equipment body and extends into the interior of the solid pollutant collection box. A first sliding groove is opened at the front end and the rear end of the inner wall of the wastewater purification equipment body. A filter screen is slidably installed inside the first sliding groove. The filter screen is fixedly connected to the sliding plate by welding. Circular holes are evenly opened on one side of the solid pollutant collection box.
[0005] The sliding plate is welded to the front and rear ends of the filter screen. First, the operator slides the sliding plate into the first sliding groove, which limits the front and rear ends of the filter screen. This prevents the filter screen from shaking as it slides into the main body of the wastewater purification equipment, allowing it to extend more stably into the solid pollutant collection box. Because the filter screen is fixed inside the main body of the wastewater purification equipment and extends into the solid pollutant collection box, it limits the solid pollutant collection box, preventing it from being pulled out of the main body of the wastewater purification equipment. A stop block is fixed inside the solid pollutant collection box, with the other side of the solid pollutant collection box contacting the filter screen, ensuring that the bottom of the filter screen is located on the inner wall of the solid pollutant collection box. Between the filter screen and the other side of the baffle, the filter screen is laterally limited to prevent the bottom of the filter screen from shaking. At this time, the solid pollutant collection box is fixedly installed on the other side of the main body of the sewage purification equipment. Then, the solid pollutants settle inside the solid pollutant collection box. The round hole clears the sewage flowing into the solid pollutant collection box, allowing the sewage to flow through the filter screen and the round hole to one side of the main body of the sewage purification equipment, thus separating the solid pollutants from the liquid pollutants. Subsequently, the nano-microbubble generator discharges nano-microbubbles into the main body of the sewage purification equipment through the air guide pipe. Then, the output end of the motor drives the stirring paddle to rotate through the rotating rod, so that the stirring paddle agitates the sewage, making the nano-microbubbles and sewage fully mixed, thereby improving the sewage treatment efficiency of the device.
[0006] Preferably, an inlet is fixedly installed on the other side of the top of the main body of the wastewater purification equipment, and a wastewater drain pipe is fixedly connected to the top of the inlet. Wastewater can be discharged into the interior of the main body of the wastewater purification equipment through the inlet and the wastewater drain pipe, which facilitates operation by staff.
[0007] Preferably, an outlet is fixedly installed through the bottom of one side of the main body of the wastewater purification equipment, and a valve is fixedly connected to the outside of the outlet. The operator opens the valve, and the purified wastewater is discharged through the outlet, improving the practicality of the device.
[0008] Preferably, a sealing ring is fixedly installed on the outer side of the other side of the solid pollutant collection box, and a stop block is fixedly connected to the bottom of the inner side of the solid pollutant collection box. The sealing ring improves the sealing of the interface of the solid pollutant collection box, preventing sewage leakage, and the stop block limits and blocks the filter screen, making the filter screen more securely installed.
[0009] Preferably, a handle is fixedly installed on the other side of the solid pollutant collection box, and an observation window is fixedly connected to the front end of the main body of the wastewater purification equipment. Operators can pull the solid pollutant collection box using the handle and observe the wastewater purification process inside the main body of the wastewater purification equipment through the observation window, thus improving the practicality of the device.
[0010] Preferably, a support leg is fixedly installed at the bottom of the main body of the wastewater purification equipment, and a base plate is fixedly connected to the bottom of the support leg. The support leg and the base plate support the main body of the wastewater purification equipment, making the main body of the wastewater purification equipment more stable.
[0011] Preferably, a second groove is provided at the bottom of the inner wall on the other side of the main body of the wastewater purification equipment. A slider fixed to the solid pollutant collection box is slidably installed inside the second groove. The slider slides inside the second groove, making the movement of the solid pollutant collection box more stable and improving the stability of the device.
[0012] An environmentally friendly water treatment process based on nano-microbubbles includes the following steps: Step 1: First, discharge industrial wastewater into the main body of the wastewater purification equipment, and then separate solid pollutants from liquid pollutants through the solid pollutant collection box and filter screen; Step 2: The nano-microbubble generator produces superoxide nano-microbubbles, which are then transported to the interior of the wastewater purification equipment through the air guide pipe. Due to the density difference in water and the squeezing force of the wastewater, the bubbles are squeezed and broken by the water pressure after being filled into the wastewater. The decomposition of the bubbles increases the dissolved oxygen and high concentration of negative oxygen ions in the water, achieving efficient decomposition of various organic waste gases and organic wastewater and breaking the molecular chain structure of organic matter, thereby purifying the wastewater. Step 3: The purified wastewater is discharged through the outlet, and solid pollutants are removed through the solid pollutant collection box 106 for further treatment.
[0013] Compared with the prior art, the beneficial effects of the present invention are: Equipped with a nano-microbubble generator, air guide pipe, motor, rotating rod, and stirring paddle, the nano-microbubble generator discharges nano-microbubbles into the main body of the wastewater purification equipment through the air guide pipe. Then, the output end of the motor drives the stirring paddle to rotate through the rotating rod, so that the stirring paddle agitates the wastewater, allowing the nano-microbubbles to be fully mixed with the wastewater, thereby improving the wastewater treatment efficiency of the device.
[0014] The system includes a solid pollutant collection box, a filter screen, a first chute, a sliding plate, and a circular hole. The sliding plate slides into the first chute, and the bottom of the filter screen extends into the solid pollutant collection box, limiting its position and fixing it to the other side of the wastewater purification equipment. Solid pollutants then settle inside the collection box, while wastewater flows through the filter screen and the circular hole to one side of the main body of the equipment. This allows solid pollutants to settle inside the collection box, preventing the mixing of fixed pollutants with nano-microbubbles during purification and ensuring that the purified water is free of solid pollutants, thus improving the wastewater purification quality.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention proposes a water treatment environmental protection process and method based on nano-microbubbles, including a sewage purification equipment body 1, a nano-microbubble generator 101, an air guide pipe 102, a motor 103, a fixing plate 3, and a protective shell 301. A rotating rod 104 is fixedly installed at the output end of the motor 103 and rotatably connected to one side of the fixing plate 3. A stirring paddle 105 is fixedly connected to the outside of the rotating rod 104. A solid pollutant collection box 106 is slid into and installed on the other side of the sewage purification equipment body 1. A filter screen 107 is slid into and installed on the other side of the top of the sewage purification equipment body 1 and extends into the interior of the solid pollutant collection box 106. The front and rear ends of the inner wall of the main body 1 of the sewage purification equipment are provided with a first sliding groove 108. A filter screen 107 is slidably installed inside the first sliding groove 108. The filter screen 107 is fixedly connected to the slide plate 109 by welding. A circular hole 302 is evenly opened on one side of the solid pollutant collection box 106. An inlet 2 is fixedly installed through the other side of the top of the main body 1 of the sewage purification equipment. A sewage drain pipe 201 is fixedly connected to the top of the inlet 2. An outlet 202 is fixedly installed through the bottom of one side of the main body 1 of the sewage purification equipment. A valve 203 is fixedly connected to the outside of the outlet 202. A sealing ring 204 is fixedly installed on the outside of the other side of the solid pollutant collection box 106. A baffle 205 is fixedly connected to the bottom of one side of the solid pollutant collection box 106.
[0019] The working principle of the water treatment environmental protection process and method based on nano-microbubbles according to Embodiment 1 is as follows: First, the operator discharges sewage into the interior of the sewage purification equipment body 1 through the inlet 2 and the sewage drain pipe 201. The sliding plate 109 is welded to the front and rear ends of the filter screen 107. Then, the sliding plate 109 is slid into the interior of the first sliding groove 108, so that the first sliding groove 108 limits the front and rear ends of the filter screen 107, thereby preventing the filter screen 107 from shaking when it slides into the interior of the sewage purification equipment body 1, and allowing it to extend more stably into the interior of the solid pollutant collection box 106. Since the filter screen 107 is fixed inside the sewage purification equipment body 1 and extends into the interior of the solid pollutant collection box 106, the filter screen 107 limits the solid pollutant collection box 106. The solid pollutant collection box 106 cannot be pulled out from the inside of the main body 1 of the sewage purification equipment, thus achieving a limiting function. The stop block 205 is fixed inside the solid pollutant collection box 106. The other side of the solid pollutant collection box 106 contacts the filter screen 107, so that the bottom of the filter screen 107 is located between the inner wall of the solid pollutant collection box 106 and the other side of the stop block 205, thus limiting the filter screen 107 laterally and preventing the bottom of the filter screen 107 from shaking. At this time, the solid pollutant collection box 106 is fixedly installed on the other side of the main body 1 of the sewage purification equipment. The sealing ring 204 makes the sealing at the interface better when the solid pollutant collection box 106 is installed at the opening on one side of the main body 1 of the sewage purification equipment. Next, solid pollutants settle inside the solid pollutant collection box 106. The round hole 302 clears the sewage flowing into the solid pollutant collection box 106, allowing the sewage to flow through the filter screen 107 and the round hole 302 to one side of the sewage purification equipment body 1, separating solid pollutants from liquid pollutants. Subsequently, the nano-microbubble generator 101 discharges nano-microbubbles into the sewage purification equipment body 1 through the air guide pipe 102. Then, the output end of the motor 103 drives the stirring paddle 105 to rotate through the rotating rod 104, causing the stirring paddle 105 to stir the sewage, making the nano-microbubbles and sewage fully mixed, improving the sewage treatment efficiency of the device. After the sewage purification is completed, the valve 203 is opened, and the purified sewage is discharged through the outlet 202. Then, the staff pulls the filter screen 107 upward, thereby lifting the filter screen 107 from the inside of the sewage purification equipment body 1 and removing it. Then, the solid pollutant collection box 106 is pulled out to treat the solid pollutants inside, so that the solids in the purified sewage can be separated from the water. This operation can be performed after the purified water is discharged. Example
[0020] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a water treatment environmental protection process and method based on nano-microbubbles. Compared with Embodiment 1, this embodiment further includes: a handle 206 fixedly installed on the other side of the solid pollutant collection box 106; an observation window 207 fixedly connected to the front end of the sewage purification equipment body 1; a support leg 208 fixedly installed at the bottom of the sewage purification equipment body 1; a base plate 209 fixedly connected to the bottom of the support leg 208; and a second sliding groove 303 opened at the bottom of the inner wall of the other side of the sewage purification equipment body 1. A slider 304 fixed to the solid pollutant collection box 106 is slidably installed inside the second sliding groove 303.
[0021] In this embodiment, as Figure 1 As shown, when the solid pollutant collection box 106 is pulled out from inside the main body 1 of the wastewater purification equipment, the solid pollutant collection box 106 drives the slider 304 to slide linearly inside the second slide groove 303, so that the solid pollutant collection box 106 will not shake when it is pulled out, thus making the movement of the solid pollutant collection box 106 more stable and improving the stability of the device. Figure 2 and Figure 4 As shown, staff can pull out the solid pollutant collection box 106 through the handle 206 to treat solid pollutants, and observe the sewage purification status inside the sewage purification equipment body 1 through the observation window 207, which improves the practicality of the device. The support legs 208 and the base plate 209 support the sewage purification equipment body 1, making the sewage purification equipment body 1 more stable.
[0022] An environmentally friendly water treatment process based on nano-microbubbles includes the following steps: Step 1: First, industrial wastewater is discharged into the main body 1 of the wastewater purification equipment, and then solid pollutants and liquid pollutants are separated through the solid pollutant collection box 106 and the filter screen 107. Step 2: The nano-microbubble generator 101 generates superoxide nano-microbubbles, which are then transported to the interior of the wastewater purification equipment 1 through the air guide pipe 102. Due to the different densities in the water and the squeezing force of the wastewater, the bubbles are squeezed and broken by the water pressure after being filled into the wastewater. The decomposition of the bubbles increases the dissolved oxygen and high concentration of oxygen negative ions in the water, thereby achieving efficient decomposition of various organic waste gases and organic wastewater and breaking the molecular chain structure of organic matter, thus purifying the wastewater. Step 3: The purified wastewater is discharged through outlet 202, and solid pollutants are removed through solid pollutant collection box 106 for further treatment.
[0023] The above specific embodiments are merely several preferred embodiments of the present invention.
