Wastewater treatment device and process for improving treatment effect

Abstract

This invention provides a wastewater treatment device that can improve treatment efficiency, comprising: a bottom tank, a main outer shell, and a second filter plate. The main outer shell is located on the top of the bottom tank, and the bottom of the main outer shell is welded and fixed to the top of the bottom tank. This invention also provides a wastewater treatment process that can improve treatment efficiency. Compared with the prior art, this invention has the following beneficial effects: By setting up a first filter plate, connecting rods, a compression chamber, a sleeve, and a receiving chamber, the wastewater falls and squeezes the first filter plate, causing the filter plate to move down and squeeze the bottom of the two sets of connecting rods. This causes the connecting rods to move down and drive the plug to move down and expose the leakage hole, allowing the potassium permanganate particles inside the receiving chamber to fall into the second filter chamber, thereby treating the wastewater and improving treatment efficiency. By setting up a motor, a rotating shaft, and a rotating drum, the motor rotates and drives the rotating shaft to rotate, thereby driving the rotating drum to rotate. This causes the two sets of stirring blades to rotate, causing the wastewater to diffuse out of the rotating drum and through the oil-absorbing cloth, thereby achieving the effect of degreasing and oil removal.

Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment equipment technology, and specifically relates to a wastewater treatment equipment and process for improving treatment efficiency. Background Technology

[0002] Industrial wastewater often contains large amounts of grease, which originates from lubricants, coolants, cutting fluids, and other substances used in industrial production. Directly discharging oily wastewater into the environment will pollute water bodies and disrupt the balance of the environment and ecosystems. Without equipment and processes to improve wastewater treatment efficiency, the following problems will arise: Oil residue: Due to a lack of efficient equipment and processes, oil in wastewater cannot be effectively removed. Oil residue leads to wastewater turbidity and increases indicators such as COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand), making it impossible for the treated wastewater to meet discharge standards.

[0003] Pollutant transfer: Without proper equipment and processes, pollutants may transfer during wastewater treatment. For example, grease may adhere to equipment surfaces or pipe walls during treatment, causing secondary oil pollution and increasing the difficulty and cost of subsequent treatment.

[0004] Low treatment efficiency: Due to a lack of efficient equipment and processes, grease in wastewater cannot be fully separated and removed. This results in the treatment process requiring more time and resources, increasing treatment costs, and reducing wastewater treatment efficiency.

[0005] Resource waste: Due to a lack of advanced equipment and processes, oil and fat resources cannot be fully recovered and utilized during wastewater treatment. Oil and fat are valuable resources that can be reused or recycled to produce other products. Without appropriate equipment and processes, these resources will be wasted.

[0006] Environmental pollution: Oil in wastewater is a harmful substance that will pollute the environment if not effectively removed. Oil will form a floating oil layer, clogging the water surface, affecting the transfer of dissolved oxygen, poisoning aquatic life, and disrupting the ecological balance.

[0007] In summary, the lack of equipment and processes to improve the treatment efficiency of industrial wastewater degreasing and oil removal will lead to a series of serious problems, including grease residue, pollutant transfer, low treatment efficiency, resource waste, and environmental pollution. Therefore, we aim to develop wastewater treatment equipment and processes that improve treatment efficiency. Summary of the Invention

[0016] As a preferred embodiment, each pressurization chamber is provided with an identical sealing chamber 1 below it, a sealing chamber 2 is provided on the right side of the left sealing chamber 1, and an identical sealing chamber 2 is provided on the left side of the right sealing chamber 1. A baffle is provided between the sealing chamber 1 and the sealing chamber 2, and a connecting hole is provided below the baffle.

Each set of sealing cavities two has an identical through hole two through its top. A sealing ring three is provided below the through hole two. Each set of sealing cavities two has an identical lifting rod inside its interior.

[0017] As a preferred embodiment, each set of lifting rods has an identical pressure plate two glued to its bottom. The lifting rods have an L-shaped structure, with the upper end of the lifting rods passing through the through hole two. The lifting rod on the left side bends 90 degrees to the right and passes through the left lifting groove. A rubber plug is provided above its right end. Symmetrical water distribution pipes are provided on the left and right sides of the bottom of the wastewater storage tank. The rubber plugs correspond to the position of the water distribution pipe on the left side of the bottom of the wastewater storage tank. The lifting rod on the right side bends 90 degrees to the left and passes through the right lifting groove. A set of identical rubber plugs is provided above its left end. The rubber plugs correspond to the position of the water distribution pipe on the right side of the bottom of the wastewater storage tank.

[0018] This invention also provides a wastewater treatment process to improve treatment efficiency, comprising the following steps: Step 1: Industrial wastewater containing grease enters the wastewater storage tank through the inlet. The wastewater flows downwards through two sets of water pipes to the top of the filter plate. The filter holes block solidified grease impurities above the filter plate. Because the filter plate has a concave structure, the wastewater will not splash out to both sides of the filter plate, thus ensuring the degreasing and oil removal effect. When the wastewater flows down and impacts the filter plate, the wastewater squeezes the filter plate and moves it downwards, thereby moving the slide bar inside the slide groove, making the downward movement of the filter plate more stable. When wastewater passes through filter plate 1, the impact force of the falling wastewater will squeeze the bottom of the left and right connecting rods, causing the two pressure blocks to squeeze the two springs 1 inside the left and right compression chambers respectively. This causes the springs 1 to contract, and the two connecting rods to move downward. Then, the two plugs at the top of the two connecting rods will detach from the two sets of leakage holes and move downward, exposing the two sets of leakage holes. This allows the potassium permanganate particles inside the two receiving chambers to fall from the leakage holes into the two sets of filter chambers. Since potassium permanganate is an oxidant, it oxidizes the organic matter in the wastewater into inorganic matter, thereby achieving the effect of degreasing and oil removal. Step two: When the slider moves downward, it squeezes the pressure head. Since the pressure head, pressure rod, and reset plate are an integrated structure, when the pressure head moves downward, the reset plate squeezes the second spring inside the pressurization chamber, causing the second spring to contract. This causes the pressure rod to move downward, which in turn causes the first pressure plate to move downward inside the first sealing chamber, thereby increasing the air pressure inside the first sealing chamber. Since the first and second sealing chambers are connected by a connecting hole, the air pressure inside the second sealing chamber increases. The increased air pressure inside the second sealing chamber then pushes the second pressure plate upward, causing the second pressure plate to move upward with the lifting rod. This causes the lifting rod to move upward along the lifting groove, ultimately causing the plug above the lifting rod to block the water distribution pipe. When the waste impacts the filter plate 1, the spring 2 rebounds and pushes the reset plate upward, resetting the reset plate and thus resetting the pressure rod and pressure head. Then, the pressure plate 1 moves upward inside the sealing cavity 1, thereby reducing the air pressure inside the sealing cavity 1 and sealing cavity 2. The pressure plate 2 moves downward, thus moving the lifting rod downward. The rubber plug disengages from the bottom of the water distribution pipe, allowing the wastewater to continue flowing. The ultimate effect is to prevent the wastewater from flowing too fast and passing through the filter plate 1 quickly, which would lead to incomplete degreasing and oil removal, resulting in grease residue and low degreasing and oil removal efficiency. Step 3: When the wastewater flows down through the filter plate into the inside of the rotating drum, the motor is started. The rotation of the motor drives the rotating shaft to rotate through the transmission mechanism. The rotation of the rotating shaft causes the rotating drum to rotate, which in turn causes the two sets of stirring blades to rotate. As a result, the wastewater diffuses out of the rotating drum under the rotation of the two sets of stirring blades, and is then continuously degreased and deoiled by the oil-absorbing cloth on the side of the rotating drum, thereby achieving the effect of degreasing and deoiling. As the wastewater passes through the rotating drum, it is simultaneously absorbed and filtered by the absorbent cotton below the drum, thus achieving the effect of degreasing and oil removal. When the stirring blades rotate, they accelerate the movement of the wastewater toward the two sets of filter plates. The wastewater enters the interior of the two sets of filter plates through the water-permeable holes on their surfaces. The activated carbon plates embedded in the two sets of filter plates adsorb and filter the oil in the wastewater, thereby achieving the effect of degreasing and oil removal. The wastewater then passes through the two sets of filter plates and enters the two sets of filter chambers.

[0019] The beneficial effects of the present invention after adopting the above technical solution are as follows: By setting up a filter plate, connecting rods, compression chamber, sleeve, and receiving chamber, the wastewater falls and squeezes the filter plate, causing the filter plate to move down and squeeze the bottom of the two sets of connecting rods. This causes the connecting rods to move down and drive the plug to move down and expose the leakage hole, allowing the potassium permanganate particles inside the receiving chamber to fall into the filter chamber, thereby treating the wastewater and improving the treatment efficiency. By setting up a motor, rotating shaft, and rotating drum, the motor rotates and drives the rotating shaft to rotate, which in turn drives the rotating drum to rotate. This causes the two sets of stirring blades to rotate, causing the wastewater to diffuse out of the rotating drum and pass through the oil-absorbing cloth, thereby achieving the effect of degreasing and removing oil and preventing oil residue. By setting up a filter plate and absorbent cotton, when the wastewater comes into contact with the absorbent cotton, the absorbent cotton absorbs the oil inside the wastewater. At the same time, the activated carbon plate degreases and removes oil from the wastewater, thereby improving the treatment efficiency. The purified wastewater can be recycled again, avoiding the waste of resources. Attached Figure Description

[0040] Please see Figure 1 , Figure 2 and Figure 3As an embodiment of the present invention: A large amount of industrial wastewater is generated during industrial production. This wastewater contains a large amount of grease. If it is discharged to the outside without treatment, it will cause serious harm to the environment and waste a lot of water resources. In order to solve the above problems, the industrial wastewater containing grease enters the wastewater storage tank 180 through the inlet 120. The wastewater flows downward to the top of the filter plate 200 through two sets of water pipes 190. The filter holes block the solidified grease impurities above the filter plate 200. Since the filter plate 200 has a concave structure, the wastewater will not splash to both sides of the filter plate 200, thus ensuring the degreasing and oil removal effect. When the wastewater flows down and impacts the filter plate 200 too fast, the wastewater squeezes the filter plate 200 and moves the filter plate 200 downward, thereby causing the slide bar 360 to move inside the slide groove 350, making the downward movement of the filter plate 200 more stable. When wastewater passes through filter plate 200, the impact of the falling wastewater squeezes the bottom of the left and right connecting rods 230, causing the two pressure blocks 240 to squeeze the two springs 270 inside the left and right compression chambers respectively. This causes the springs 270 to contract, and the two connecting rods 230 to move downward. Consequently, the two plugs at the top of the two connecting rods 230 detach from the two sets of leakage holes and move downward, exposing the two sets of leakage holes. This allows the potassium permanganate particles inside the two sets of receiving chambers 210 to fall from the leakage holes into the two sets of filter chambers 550. Since potassium permanganate is an oxidant, it oxidizes the organic matter in the wastewater into inorganic matter, thereby achieving the effect of degreasing and oil removal.

[0041] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 As another embodiment of the present invention: based on the further explanation of the above embodiment, when the slide bar 360 moves downward, it squeezes the pressure head 430. Since the pressure head 430, the pressure rod 440 and the reset plate 460 are an integral structure, when the pressure head 430 moves downward, the reset plate 460 squeezes the second spring 470 inside the pressure chamber 450, causing the second spring 470 to contract, thereby causing the pressure rod 440 to move downward, and then causing the first pressure plate 390 to move downward inside the first sealing chamber 370, thereby increasing the air pressure inside the first sealing chamber 370. Since the first sealing chamber 370 and the second sealing chamber 380 are connected through the connecting hole 410, the air pressure inside the second sealing chamber 380 increases. The increased air pressure inside the second sealing chamber 380 then pushes the second pressure plate 400 upward, causing the second pressure plate 400 to move upward with the lifting rod 250, thereby causing the lifting rod 250 to move upward along the lifting groove 420, and finally causing the plug above the lifting rod 250 to block the water pipe 190. When the waste-free impact filter plate 200 is activated, spring 470 rebounds and pushes the reset plate 460 upward, resetting the reset plate 460 and thus resetting the pressure rod 440 and pressure head 430. Subsequently, pressure plate 390 moves upward inside the sealing cavity 370, thereby reducing the air pressure inside the sealing cavity 370 and sealing cavity 380. Pressure plate 400 moves downward, thus moving the lifting rod 250 downward. The rubber plug 260 disengages from the bottom of the water distribution pipe 190, allowing the wastewater to continue flowing. The ultimate effect is to prevent the wastewater from flowing too fast and passing through the filter plate 200 too quickly, which would lead to incomplete degreasing and oil removal, resulting in grease residue and low degreasing and oil removal efficiency.

[0042] Please see Figure 2 , Figure 6 , Figure 7 and Figure 8 As a third embodiment of the present invention: based on the further explanation of the above embodiments, when the wastewater flows down through the filter plate 200 into the inside of the rotating drum 290, the motor 330 is started. The rotation of the motor 330 drives the rotating shaft 310 to rotate through the transmission mechanism. The rotation of the rotating shaft 310 causes the rotating drum 290 to rotate. The rotation of the rotating drum 290 causes the two sets of stirring blades 510 to rotate, so that the wastewater diffuses out of the rotating drum 290 under the rotation of the two sets of stirring blades 510. Then, it is continuously degreased and deoiled by the oil-absorbing cloth 520 on the side of the rotating drum 290, thereby achieving the effect of degreasing and deoiling. When the wastewater is inside the rotating drum 290, it is simultaneously absorbed and filtered by the adsorption cotton 320 below the rotating drum 290, thereby achieving the effect of degreasing and oil removal. When the stirring blade 510 rotates, it accelerates the movement of the wastewater towards the two sets of filter plates 280. The wastewater enters the interior of the two sets of filter plates 280 through the water permeable holes on the surface of the two sets of filter plates 280. The activated carbon plates 300 embedded in the two sets of filter plates 280 adsorb and filter the oil in the wastewater, thereby achieving the effect of degreasing and oil removal. The wastewater passes through the two sets of filter plates 280 and enters the interior of the two sets of filter chambers 550, where it is oxidized by the potassium permanganate particles inside the filter chambers 550, thereby degreasing and oil removal.

[0043] Please see Figure 1 and Figure 2 As a fourth embodiment of the present invention: Based on the further explanation of the above embodiments, the wastewater treatment process inside the equipment is observed through the observation window 140 to prevent equipment malfunctions and make timely adjustments. After the wastewater treatment is completed, the two sets of stop valves 160 are opened so that the treated wastewater enters the water storage chambers 540 on both sides of the base through the two sets of outlet pipes 150, thereby completing the collection of the treated wastewater and avoiding the waste of water resources. When it is needed, the two sets of outlets 170 are opened to collect the treated wastewater inside.

[0044] Please see Figures 1 to 7The present invention also provides a wastewater treatment process for improving treatment efficiency, comprising the following steps: Step 1: Industrial wastewater containing grease enters the wastewater storage tank 180 through the inlet 120. The wastewater flows downward through two-part water pipes 190 to the top of the filter plate 200. The filter holes block solidified grease impurities above the filter plate 200. Since the filter plate 200 has a concave structure, the wastewater will not splash out to the sides of the filter plate 200, thus ensuring the degreasing and oil removal effect. When the wastewater flows down and impacts the filter plate 200 too fast, the wastewater squeezes the filter plate 200, causing the filter plate 200 to move downward, thereby causing the slide bar 360 to move inside the slide groove 350, making the downward movement of the filter plate 200 more stable. When wastewater passes through filter plate 200, the impact of the falling wastewater squeezes the bottom of the left and right connecting rods 230, causing the two pressure blocks 240 to squeeze the two springs 270 inside the left and right compression chambers respectively. This causes the springs 270 to contract, and the two connecting rods 230 to move downward. Consequently, the two plugs at the top of the two connecting rods 230 detach from the two sets of leakage holes and move downward, exposing the two sets of leakage holes. This allows the potassium permanganate particles inside the two sets of receiving chambers 210 to fall from the leakage holes into the two sets of filter chambers 550. Since potassium permanganate is an oxidant, it oxidizes the organic matter in the wastewater into inorganic matter, thereby achieving the effect of degreasing and oil removal.

[0045] Step 2: When the slider 360 moves downward, it squeezes the pressure head 430. Since the pressure head 430, pressure rod 440 and reset plate 460 are an integral structure, when the pressure head 430 moves downward, the reset plate 460 squeezes the spring 470 inside the pressure chamber 450, causing the spring 470 to contract, thereby causing the pressure rod 440 to move downward, and then causing the pressure plate 390 to move downward inside the sealing chamber 370, thereby increasing the air pressure inside the sealing chamber 370. Since the sealing chamber 370 and the sealing chamber 380 are connected by the connecting hole 410, the air pressure inside the sealing chamber 380 increases. The increased air pressure inside the sealing chamber 380 then pushes the pressure plate 400 upward, causing the pressure plate 400 to move upward with the lifting rod 250, and then causing the lifting rod 250 to move upward along the lifting groove 420, finally causing the plug above the lifting rod 250 to block the water pipe 190. When the waste-free impact filter plate 200 is activated, spring 470 rebounds and pushes the reset plate 460 upward, resetting the reset plate 460 and thus resetting the pressure rod 440 and pressure head 430. Subsequently, pressure plate 390 moves upward inside the sealing cavity 370, thereby reducing the air pressure inside the sealing cavity 370 and sealing cavity 380. Pressure plate 400 moves downward, thus moving the lifting rod 250 downward. The rubber plug 260 disengages from the bottom of the water distribution pipe 190, allowing the wastewater to continue flowing. The ultimate effect is to prevent the wastewater from flowing too fast and passing through the filter plate 200 too quickly, which would lead to incomplete degreasing and oil removal, resulting in grease residue and low degreasing and oil removal efficiency.

[0046] Step 3: When the wastewater flows down through the filter plate 200 into the rotating drum 290, the motor 330 is started. The rotation of the motor 330 drives the rotating shaft 310 to rotate through the transmission mechanism. The rotation of the rotating shaft 310 causes the rotating drum 290 to rotate. The rotation of the rotating drum 290 causes the two sets of stirring blades 510 to rotate, so that the wastewater diffuses out of the rotating drum 290 under the rotation of the two sets of stirring blades 510. Then, it is continuously degreased and deoiled by the oil-absorbing cloth 520 on the side of the rotating drum 290, thereby achieving the effect of degreasing and deoiling. Inside the drum 290, the wastewater is simultaneously absorbed and filtered by the adsorption cotton 320 below the drum 290, thus achieving the effect of degreasing and oil removal. When the stirring blades 510 rotate, the wastewater moves faster towards the two sets of filter plates 280. The wastewater enters the interior of the two sets of filter plates 280 through the water-permeable holes on the surface of the two sets of filter plates 280. The activated carbon plates 300 embedded in the two sets of filter plates 280 adsorb and filter the oil in the wastewater, thereby achieving the effect of degreasing and oil removal. The wastewater passes through the two sets of filter plates 280 and enters the interior of the two sets of filter chambers 550, where it is oxidized by the potassium permanganate particles inside the filter chambers 550, thereby degreasing and oil removal.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The rear side of each set of top covers (130) is hinged to the top of the main body shell (110) through a hinge post. A set of identical handles are installed on the top of each set of top covers (130).

6. A method for treating industrial wastewater containing oil, using the wastewater treatment equipment as described in claim 5, characterized in that: Includes the following steps: Step 1: Industrial wastewater containing grease enters the wastewater storage tank (180) through the inlet (120). The wastewater flows downward through two sets of water pipes (190) to the top of the filter plate (200). The filter holes block the solidified grease impurities above the filter plate (200). Since the filter plate (200) has a concave structure, the wastewater will not splash to the sides of the filter plate (200), thus ensuring the degreasing and oil removal effect. When the wastewater flows down and impacts the filter plate (200) too fast, the wastewater squeezes the filter plate (200) and causes the filter plate (200) to move downward, thereby causing the slide bar (360) to move inside the slide groove (350), making the downward movement of the filter plate (200) more stable. When wastewater passes through filter plate 1 (200), the impact force of the falling wastewater will squeeze the bottom of the two sets of connecting rods (230) on the left and right sides, causing the two sets of pressure blocks (240) to squeeze the two sets of springs 1 (270) inside the two sets of compression chambers on the left and right sides respectively. This causes the springs 1 (270) to contract, and the two sets of connecting rods (230) to move downwards. Then, the two sets of plugs at the top of the two sets of connecting rods (230) will detach from the two sets of leakage holes and move downwards, exposing the two sets of leakage holes. This allows the potassium permanganate particles inside the two sets of receiving chambers (210) to fall from the leakage holes into the two sets of filter chambers (550). Since potassium permanganate is an oxidant, it oxidizes the organic matter in the wastewater into inorganic matter, thereby achieving the effect of degreasing and oil removal. Step two: When the slider (360) moves downward, it squeezes the pressure head (430). Since the pressure head (430), pressure rod (440), and reset plate (460) are an integral structure, when the pressure head (430) moves downward, the reset plate (460) squeezes the second spring (470) inside the pressure chamber (450), causing the second spring (470) to contract, thereby causing the pressure rod (440) to move downward, which in turn causes the first pressure plate (390) to move downward inside the first sealing cavity (370), thereby increasing the pressure inside the first sealing cavity (370). The air pressure in the part is increased because the sealing cavity one (370) and the sealing cavity two (380) are connected through the connecting hole (410). The increased air pressure in the sealing cavity two (380) then pushes the pressure plate two (400) upward, causing the pressure plate two (400) to move upward with the lifting rod (250), which in turn causes the lifting rod (250) to move upward along the lifting groove (420), and finally causes the rubber plug above the lifting rod (250) to block the water distribution pipe (190). When no wastewater impacts the filter plate 1 (200), the spring 2 (470) rebounds and pushes the reset plate (460) upward, so that the reset plate (460) resets, thereby resetting the pressure rod (440) and the pressure head (430). Then, the pressure plate 1 (390) moves upward inside the sealing cavity 1 (370), thereby reducing the air pressure inside the sealing cavity 1 (370) and the sealing cavity 2 (380). The pressure plate 2 (400) moves downward, thereby moving the lifting rod (250) downward. The rubber plug (260) disengages from the bottom of the water distribution pipe (190), and then the wastewater continues to flow. The final effect is to prevent the wastewater from flowing too fast and passing through the filter plate 1 (200) too quickly, resulting in incomplete degreasing and oil removal, thus causing grease residue and low degreasing and oil removal efficiency. Step 3: When the wastewater flows down through the filter plate (200) into the rotating drum (290), the motor (330) is started. The rotation of the motor (330) drives the rotating shaft (310) to rotate through the transmission mechanism. The rotation of the rotating shaft (310) causes the rotating drum (290) to rotate. The rotation of the rotating drum (290) causes the two sets of stirring blades (510) to rotate. As a result, the wastewater diffuses out of the rotating drum (290) under the rotation of the two sets of stirring blades (510), and is then continuously degreased and deoiled by the oil-absorbing cloth (520) on the side of the rotating drum (290), thereby achieving the effect of degreasing and deoiling. When the wastewater is inside the rotating drum (290), it is simultaneously absorbed and filtered by the adsorption cotton (320) below the rotating drum (290), thereby achieving the effect of degreasing and oil removal. When the stirring blade (510) rotates, it accelerates the movement of the wastewater towards the two sets of filter plates (280). The wastewater enters the interior of the two sets of filter plates (280) through the water-permeable holes on the surface of the two sets of filter plates (280). The activated carbon plates (300) embedded in the interior of the two sets of filter plates (280) adsorb and filter the oil in the wastewater, thereby achieving the effect of degreasing and oil removal. The wastewater passes through the two sets of filter plates (280) and enters the interior of the two sets of filter chambers (550) respectively.
