Description

Technical Field

[0001] This invention relates to the technical field of environmental protection in construction projects, and in particular to a wastewater treatment device and method for environmental protection in construction projects. Background Technology

[0002] Construction projects are systematic construction activities aimed at fixed asset investment. Their core characteristic is that they realize the construction of the physical project through surveying, design, construction and other stages, and involve public safety, social welfare or commercial development.

[0003] During construction projects, a large amount of wastewater is generated during concrete mixing, pouring, and curing. This wastewater contains suspended solids and alkaline substances such as cement, sand, gravel, and additives. When cleaning construction machinery, oil, lubricants, and metal particles are mixed into the water. Chemical waste liquids are also generated from surface treatment of building materials (such as rust removal and painting). If the wastewater generated in construction projects is discharged directly without treatment, it will seriously pollute surface water and groundwater resources. In order to avoid damaging the ecological environment, wastewater needs to be treated. In the process of using existing wastewater treatment devices, the wastewater is often filtered through a filter screen. If the wastewater contains oil, the treatment efficiency of the wastewater is not good enough. Summary of the Invention

[0011] As a preferred embodiment of the wastewater treatment device for environmental protection in construction projects according to the present invention, the discharge component includes two discharge ports and two receiving blocks. The two discharge ports are respectively opened on the left and right sides of the front side of the tank, and the rear sides of the two receiving blocks are fixedly connected to the front side of the tank.

[0012] As a preferred embodiment of the wastewater treatment device for environmental protection in construction projects according to the present invention, the leak-proof component includes a leak-proof plate and two electric telescopic columns.

The bottom of the output end of the two electric telescopic columns is fixedly connected to the top of the leak-proof plate, and the rear side of the two electric telescopic columns is fixedly connected to the front side of the tank.

[0013] As a preferred embodiment of the wastewater treatment device for environmental protection in construction projects according to the present invention, a long rod is fixedly connected to the right side of the baffle, and a sealing block is fixedly connected to the bottom of the long rod.

[0014] As a preferred embodiment of the wastewater treatment device for environmental protection in construction projects according to the present invention, wherein: a second motor is fixedly connected to the bottom of the tank, a stirrer is fixedly connected to the top of the output end of the second motor, and the bottom of the stirrer is rotatably connected to the bottom of the tank.

[0015] The beneficial effects of this invention are as follows: the air injection component can inject air into the sewage at the top and bottom of the tank, causing impurities in the sewage to float to the surface. The blocking component can discharge the floating oil and impurities in the sewage. At the same time, it drives the regulating component, which guides the gas inside the first air pipe to the surface of the sewage, causing the sewage to flow to the left and accelerating the discharge of oil and impurities. As the blocking component moves, it also causes the sealing block to move down, allowing the sewage after oil treatment to flow down. During the downward flow, flocculant is injected, and the sewage and flocculant are mixed by the agitator. The cleaning component can discharge the generated impurities to the outside of the tank.

[0016] In view of the problems existing in the current wastewater treatment methods for environmental protection in construction projects, this invention is proposed.

[0018] To solve the above-mentioned technical problems, the present invention provides the following technical solution: First, wastewater is injected into the interior of the tank, and then an air bubble generator is run to inject air; Then, the floating oil and impurities are drained through the plugging components, and the wastewater flows downstream; Finally, flocculant is added in the downstream process, and then the mixture is rotated and stirred by the agitator to make the impurities in the wastewater float to the surface.

[0019] As a preferred embodiment of the wastewater treatment method for environmental protection in construction projects described in this invention, the following steps are taken: an aeration component can inject air into the wastewater to make impurities float to the surface; a blocking component can discharge impurities and floating oil from the surface of the wastewater; an adjustment component can change the gas path inside the first air pipe; a cleaning component can clean the impurities; a discharge component and a leak-proof component can discharge the impurities to the outside of the tank; and a stirrer can mix the wastewater with the flocculant.

[0020] The beneficial effects of this invention are as follows: When wastewater is mixed with flocculant, by blocking the outlet of the baffle, wastewater can continue to be injected into the tank, so that the wastewater is located at the top of the baffle. Under the action of the bubble generator, air is injected into the wastewater at the top and bottom of the tank at the same time. At this time, while the wastewater is mixed with flocculant, the oil in the wastewater can also be treated. After the mixing is completed and the wastewater is discharged, the wastewater after the oil is removed can be treated, reducing the operation time of wastewater treatment.

[0033] Example 1 Reference Figures 1-8 As a first embodiment of the present invention, an environmentally friendly wastewater treatment method for construction projects is provided, which enables the discharge of oil and impurities from wastewater.

[0034] First, wastewater is injected into the tank 101a, and then the bubble generator 101d is run to inject air, causing the oil and impurities in the wastewater to float to the surface.

[0035] Then, the floating oil and impurities are discharged through the blocking component 102, and the sealing block 102a-2 is opened to allow the sewage to flow down. By adjusting the component 103, the discharge speed of the floating oil and impurities can be accelerated. The sewage flows down and passes through the filter screen 201a, which intercepts impurities in the sewage. Flocculant is added to the wastewater during the downstream process, and then the wastewater is mixed by the rotating agitator 101a-2 to make the impurities in the wastewater float to the surface.

[0036] Finally, the two discharge ports 202a are not blocked by the leak-proof component 203. At this time, the impurities can be discharged to the outside of the tank 101a by the cleaning component 201.

[0037] Example 2 Reference Figures 1-8In the second embodiment of the present invention, an air injection component 101, a blocking component 102, an adjusting component 103, a long rod 102a-1, and a sealing block 102a-2 are provided. The air injection component 101, the blocking component 102, the adjusting component 103, the long rod 102a-1, and the sealing block 102a-2 are used to treat floating oil and floating impurities in sewage.

[0038] The oil removal mechanism 100 includes an air injection component 101. A blocking component 102 is provided on the left side of the air injection component 101. The air injection component 101 includes a tank 101a. A first air pipe 101b and a second air pipe 101c are fixedly connected to the right side inside the tank 101a. A bubble generator 101d is fixedly connected to the top of the first air pipe 101b and the second air pipe 101c. A baffle 101e is fixedly connected to the bottom inside the tank 101a. An oil float sensor 101f is fixedly connected to the rear side of the top inside the tank 101a. An adjusting component 103 is provided at the top inside the first air pipe 101b.

[0039] The blocking component 102 includes a baffle 102a, a connecting block 102b, a cylinder 102c, and an oil discharge block 102d. The surface of the baffle 102a is slidably connected to the top of the left side of the inside of the tank 101a. The top of the right side of the connecting block 102b is fixedly connected to the left side of the baffle 102a. The bottom of the connecting block 102b is fixedly connected to the top of the output end of the cylinder 102c. The right side of the cylinder 102c is fixedly connected to the left side of the tank 101a. The top of the right side of the oil discharge block 102d is fixedly connected to the top of the left side of the tank 101a.

[0040] The adjusting component 103 includes a rotating block 103a. The bottom of the rotating block 103a is rotatably connected to the inside of the first air pipe 101b. A movable rod 103b is rotatably connected to the bottom left side of the rotating block 103a. A lifting block 103c is rotatably connected to the left side of the movable rod 103b. An extension 103d is provided on the left side of the lifting block 103c. The surface of the lifting block 103c is slidably connected to the inside of the first air pipe 101b. A sliding plate 103e is fixedly connected to the right side of the surface of the lifting block 103c.

[0041] The extension 103d includes a housing 103d-1, a moving column 103d-2, and a return spring 103d-3. The bottom of the housing 103d-1 is fixedly connected to the top of the connecting block 102b. The surface of the moving column 103d-2 is slidably connected to the inside of the housing 103d-1. The return spring 103d-3 is sleeved on the surface of the moving column 103d-2. The bottom of the return spring 103d-3 is fixedly connected to the bottom of the moving column 103d-2. The top of the return spring 103d-3 is fixedly connected to the top of the inside of the housing 103d-1. The side of the moving column 103d-2 near the lifting block 103c is fixedly connected to the lifting block 103c.

[0042] A long rod 102a-1 is fixedly connected to the right side of the baffle 102a, and a sealing block 102a-2 is fixedly connected to the bottom of the long rod 102a-1. The surface of the sealing block 102a-2 is inserted into the left side of the partition 101e.

[0043] Specifically, the oil float sensor 101f can monitor the thickness of the oil float in real time. When the oil float is thick, it will automatically drive the cylinder 102c to open the baffle 102a and discharge the oil float and floating impurities. The first air pipe 101b injects air into the unfiltered wastewater, and the second air pipe 101c injects air into the filtered wastewater. Filter material can be installed at the bottom of both the first air pipe 101b and the second air pipe 101c. The surface of the connecting block 102b is slidably connected to the inside of the oil discharge block 102d. The surface of the baffle 102a fits snugly against the inside of the tank 101a, and the connection can be sealed with a sealing material. The output end of the cylinder 102c slowly descends, and as the baffle 102a moves downward, the oil float and impurities on top of the wastewater will tilt and flow away. The two sliding plates 103e slide and fit against the surface and interior of the first air pipe 101b respectively to prevent air leakage. The lifting block 103c moves up and down, which drives the movable rod 103b to move the rotating block 103a. The rotating block 103a rotates through the interior of the first air pipe 101b, thereby changing the gas path inside the first air pipe 101b. The surface of the sealing block 102a-2 fits against the interior of the baffle 101e. The sealing block 102a-2 and the long rod 102a-1 move with the baffle 102a. As the floating oil and impurities are discharged, the sealing block 102a-2 will gradually move to the bottom of the baffle 101e. At this time, the sewage will flow down through the baffle 101e.

[0044] Furthermore, when wastewater treatment is required, the wastewater is first injected into the interior of tank 101a, and then the bubble generator 101d is operated. The bubble generator 101d injects air into the wastewater through the first air pipe 101b, causing the oil and impurities in the wastewater to float to the surface.

[0045] When the floating oil sensor 101f detects that the floating oil thickness has reached the set value, the cylinder 102c will be activated automatically. The output end of the cylinder 102c will cause the connecting block 102b to drive the baffle 102a to slowly descend. As the baffle 102a descends, a gap is formed at the top left side of the tank 101a. The floating oil and impurities on the surface of the sewage will flow to the left and be discharged through the flow into the interior of the oil discharge block 102d.

[0046] As the connecting block 102b descends, it will cause the outer casing 103d-1, the moving column 103d-2, and the lifting block 103c to descend. The lifting block 103c will cause the movable rod 103b to descend, and the movable rod 103b will cause the rotating block 103a to rotate through the inside of the first air pipe 101b. At this time, because the rotating block 103a rotates to the left, the gas path inside the first air pipe 101b will change, and the gas will blow towards the top of the sewage, blowing the floating oil and impurities to the left, increasing the discharge speed of the floating oil and impurities. As the connecting block 102b gradually descends, when the left side of the rotating block 103a is in contact with the inside of the first air pipe 101b, the moving column 103d-2 will squeeze the return spring 103d-3 to increase the stroke, and the connecting block 102b will move down normally.

[0047] As the connecting block 102b descends, the long rod 102a-1 will also cause the sealing block 102a-2 to descend. As the baffle 102a gradually descends, the floating oil and impurities will gradually flow out. The sealing block 102a-2 will move to the bottom of the baffle 101e. When the sewage moves down through the baffle 101e, flocculant is injected and will flow with the sewage.

[0048] Example 3 Reference Figures 1-8 In the third embodiment of the present invention, a cleaning component 201, a discharge component 202, a leak-proof component 203, a second motor 101a-1, and a stirrer 101a-2 are provided. Through the cleaning component 201, the discharge component 202, the leak-proof component 203, the second motor 101a-1, and the stirrer 101a-2, it is possible to mix sewage with flocculant and to discharge the impurities intercepted by the filter screen 201a and the impurities after mixing with flocculant separately.

[0049] The impurity removal mechanism 200 includes a cleaning component 201, a discharge component 202, and a leak-proof component 203. The discharge component 202 is located on the front side of the tank 101a, and the leak-proof component 203 is located on the front side of the discharge component 202. The cleaning component 201 is located at the bottom inside the tank 101a. The cleaning component 201 includes a filter screen 201a, a first motor 201b, a rotating rod 201c, a first cleaning plate 201d, and a second cleaning plate 201e. The surface of the filter screen 201a is fixedly connected to the inside of the tank 101a. The bottom of the first motor 201b is fixedly connected to the top of the partition plate 101e. The top of the rotating rod 201c is fixedly connected to the bottom of the output end of the first motor 201b. The sides of the first cleaning plate 201d and the second cleaning plate 201e closest to the rotating rod 201c are both fixedly connected to the rotating rod 201c.

[0050] The discharge component 202 includes two discharge ports 202a and two receiving blocks 202b. The two discharge ports 202a are respectively opened on the left and right sides of the front side of the tank body 101a, and the rear sides of the two receiving blocks 202b are fixedly connected to the front side of the tank body 101a.

[0051] The leak-proof component 203 includes a leak-proof plate 203a and two electrically operated telescopic columns 203b. The rear side of the leak-proof plate 203a is slidably connected to the front side of the tank body 101a. The bottom of the output end of the two electrically operated telescopic columns 203b is fixedly connected to the top of the leak-proof plate 203a, and the rear side of the two electrically operated telescopic columns 203b is fixedly connected to the front side of the tank body 101a.

[0052] A second motor 101a-1 is fixedly connected to the bottom of the tank 101a, and a stirrer 101a-2 is fixedly connected to the top of the output end of the second motor 101a-1. The bottom of the stirrer 101a-2 is rotatably connected to the bottom inside the tank 101a.

[0053] Specifically, the surface of the rotating rod 201c is rotatably connected to the interior of the partition 101e and the filter screen 201a; the bottom of the first cleaning plate 201d is rotatably connected to and fits against the top of the filter screen 201a; the top of the second cleaning plate 201e is rotatably connected to and fits against the bottom of the filter screen 201a. The first cleaning plate 201d is used to clean impurities on the top of the filter screen 201a; the second cleaning plate 201e is used to clean floating impurities after mixing the flocculant. Two receiving blocks 202b are located at the two discharge ports 201a respectively. At the bottom of 2a, the left discharge port 202a and the receiving block 202b are used to discharge impurities filtered by the filter screen 201a, and the right discharge port 202a and the right receiving block 202b are used to discharge impurities of the mixed flocculant. The rear side of the leak-proof plate 203a is attached to the front side of the tank body 101a, and a sealing layer is installed on the rear side inside the leak-proof plate 203a to prevent leakage when the leak-proof plate 203a moves to the front side of the two discharge ports 202a. The connection between the agitator 101a-2 and the tank body 101a is sealed with a sealing material. When the sewage flows down, flocculant is added to the sewage, so that the flocculant falls with the sewage. The agitator 101a-2 is driven to rotate by the second motor 101a-1 to mix the sewage with the flocculant.

[0054] Furthermore, the wastewater will pass through filter screen 201a, which will intercept impurities in the wastewater. Finally, it will flow to the bottom of the tank 101a and run the second motor 101a-1. The output of the second motor 101a-1 will cause the agitator 101a-2 to rotate. The agitator 101a-2 will mix the wastewater with the flocculant, and the impurities generated by the mixture will float to the surface.

[0055] When impurities need to be cleaned, the two electric telescopic columns 203b and the first motor 201b are operated. The output ends of the two electric telescopic columns 203b will cause the anti-leakage plate 203a to move upward, and the anti-leakage plate 203a will disengage from the two discharge ports 202a.

[0056] The operation of the first motor 201b will cause the rotating rod 201c to drive the first cleaning plate 201d and the second cleaning plate 201e to rotate. The first cleaning plate 201d will scrape off the impurities on the top of the filter screen 201a and then discharge them through the left discharge port 202a and the left receiving block 202b. The second cleaning plate 201e will rotate and push the impurities floating in the sewage, so that the impurities will be discharged through the right discharge port 202a and the right receiving block 202b. After the impurities are cleaned, the sewage can be discharged through the bottom of the left side of the tank 101a.

[0057] After the sewage at the top of the baffle 101e has finished flowing out, the sealing block 102a-2 is used to block the baffle 101e. At this time, sewage can continue to be injected into the tank 101a. Due to the obstruction of the baffle 101e, the floating oil and impurities are caused to float to the surface by the air injection through the first air pipe 101b. After the sewage mixed with flocculant is discharged, the sealing block 102a-2 is opened again to allow the de-oiled sewage to flow down, thus achieving simultaneous treatment of de-oiling and impurity removal by mixed flocculant.

[0058] The remaining structure is the same as that in Example 2.

[0059] Example 4 Reference Figures 1-8 This is the fourth embodiment of the present invention, which differs from the third embodiment in that it provides an environmentally friendly wastewater treatment device for construction projects.

[0060] When wastewater treatment is required, the wastewater is first injected into the tank 101a, and then the bubble generator 101d is run. The bubble generator 101d injects air into the wastewater through the first air pipe 101b, causing the oil and impurities in the wastewater to float to the surface.

[0061] When the floating oil sensor 101f detects that the floating oil thickness has reached the set value, the cylinder 102c will be activated automatically. The output end of the cylinder 102c will cause the connecting block 102b to drive the baffle 102a to slowly descend. As the baffle 102a descends, a gap is formed at the top left side of the tank 101a. The floating oil and impurities on the surface of the sewage will flow to the left and be discharged through the flow into the interior of the oil discharge block 102d.

[0062] As the connecting block 102b descends, it will cause the outer casing 103d-1, the moving column 103d-2, and the lifting block 103c to descend. The lifting block 103c will cause the movable rod 103b to descend, and the movable rod 103b will cause the rotating block 103a to rotate through the inside of the first air pipe 101b. At this time, because the rotating block 103a rotates to the left, the gas path inside the first air pipe 101b will change, and the gas will blow towards the top of the sewage, blowing the floating oil and impurities to the left, increasing the discharge speed of the floating oil and impurities. As the connecting block 102b gradually descends, when the left side of the rotating block 103a is in contact with the inside of the first air pipe 101b, the moving column 103d-2 will squeeze the return spring 103d-3 to increase the stroke, and the connecting block 102b will move down normally.

[0063] As the connecting block 102b descends, the long rod 102a-1 will also cause the sealing block 102a-2 to descend. As the baffle 102a gradually descends, the floating oil and impurities will gradually flow out. The sealing block 102a-2 will move to the bottom of the baffle 101e. When the sewage moves down through the baffle 101e, flocculant is injected and will flow with the sewage.

[0064] Wastewater passes through filter screen 201a, which intercepts impurities in the wastewater. Finally, the wastewater flows to the bottom of the tank 101a and runs the second motor 101a-1. The output of the second motor 101a-1 causes the agitator 101a-2 to rotate. The agitator 101a-2 mixes the wastewater with the flocculant, and the impurities produced by the mixture float to the surface.

[0065] When impurities need to be cleaned, the two electric telescopic columns 203b and the first motor 201b are operated. The output ends of the two electric telescopic columns 203b will cause the anti-leakage plate 203a to move upward, and the anti-leakage plate 203a will disengage from the two discharge ports 202a.

[0066] The operation of the first motor 201b will cause the rotating rod 201c to drive the first cleaning plate 201d and the second cleaning plate 201e to rotate. The first cleaning plate 201d will scrape off the impurities on the top of the filter screen 201a and then discharge them through the left discharge port 202a and the left receiving block 202b. The second cleaning plate 201e will rotate and push the impurities floating in the sewage, so that the impurities will be discharged through the right discharge port 202a and the right receiving block 202b. After the impurities are cleaned, the sewage can be discharged through the bottom of the left side of the tank 101a.

[0067] After the sewage at the top of the baffle 101e has finished flowing out, the sealing block 102a-2 is used to block the baffle 101e. At this time, sewage can continue to be injected into the tank 101a. Due to the obstruction of the baffle 101e, the floating oil and impurities are caused to float to the surface by the air injection through the first air pipe 101b. After the sewage mixed with flocculant is discharged, the sealing block 102a-2 is opened again to allow the de-oiled sewage to flow down, thus achieving simultaneous treatment of de-oiling and impurity removal by mixed flocculant.

[0068] In summary, by using the blocking component 102, when the sewage at the bottom of the tank 101a is mixing with the flocculant, the sewage at the top of the tank 101a can continue to cause oil and impurities to float to the surface under the action of the bubble generator 101d, thus achieving simultaneous operation. When the sewage after mixing with the flocculant is discharged, the sewage containing oil and floating impurities can continue to mix with the flocculant as it flows downstream, increasing work efficiency and enabling the separation of oil and impurities from the sewage.
