[0002] During the construction process of construction engineering, a large amount of sewage will be generated. The composition of the sewage is complex, usually containing suspended silt particles, leaked grease of construction machinery, alkaline substances generated during concrete curing, and dissolved pollutants dissolved from building materials. If the untreated sewage is directly discharged, not only will it pollute the surrounding soil, groundwater and surface water, and destroy the ecological environment, but it may also violate environmental regulations, leading to project suspension and rectification, increasing construction costs.

[0003] At present, the main sewage treatment methods in construction engineering are sedimentation tank treatment and independent combined sewage treatment.

The discharge frame 14 is fixedly installed on the outside of the pretreatment tank 2, and the end of the vibrating screen 40 near the discharge frame 14 is open. The operator can adjust the horizontal angle of the vibrating screen 40 through the first motor 13. The opening of the vibrating screen 40 faces downwards and is aligned with the top of the discharge frame 14, facilitating the discharge of collected particulate impurities. A guide hopper 15 is fixedly installed inside the pretreatment box 2, and the guide hopper 15 is located directly above the centrifuge cylinder 9. A positioning shaft 16 is fixedly installed on the outside of the centrifuge cylinder 9, and the positioning shaft 16 is rotatably mounted inside the pretreatment box 2.

A first gear 19 that meshes with the gear ring 17 is fixedly installed at the output end of the second motor 18, enabling the second motor 18 to drive the gear ring 17 to rotate through the first gear 19. The gear ring 17 then drives the centrifuge cylinder 9 to rotate at high speed. After the wastewater enters the centrifuge cylinder 9, under the action of centrifugal force, the denser silt particles quickly settle to the bottom of the centrifuge cylinder 9. The pretreated wastewater enters the primary treatment tank 3 through the first drain valve. The bottom of the centrifuge cylinder 9 has a hollow frustum structure to facilitate the temporary storage of silt. A sludge discharge valve 20 is fixedly installed at the bottom of the centrifuge cylinder 9, and the sludge stored in the centrifuge cylinder 9 is periodically discharged through the sludge discharge valve 20. A water inlet cylinder 32 is fixedly installed at the inlet end of the reverse osmosis membrane module 8. An ultraviolet lamp 33 is fixedly installed on the inner side of the water inlet cylinder 32. The ultraviolet lamp 33 oxidizes and decomposes the organic pollutants in the wastewater entering the water inlet cylinder 32.

The adsorption frame 7 is slidably installed on the inner side of the insertion frame 36, and one side of the adsorption frame 7 extends to the outside of the secondary treatment box 4, which is convenient for the activated carbon and composite adsorption material in the adsorption frame 7 to be replaced regularly.

[0032] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The oil removal mechanism shown in the figure includes a conveyor belt 10 disposed on the outside of the inclined plate 6. The conveyor belt 10 can continuously discharge floating grease. The oil removal mechanism also includes two positioning plates 21 symmetrically fixedly installed on the outside of the inclined plate 6. The inner side of the primary processing box 3 is provided with a positioning groove for the positioning plates 21 to be inserted and positioned, which facilitates the installation of the inclined plate 6. Both ends of the inclined plate 6 are arc-shaped structures, so that the conveyor belt 10 can be fitted onto the outside of the inclined plate 6. Two symmetrically distributed rotating rods 22 are rotatably installed on the inner side of the inclined plate 6. Both ends of the rotating rods 22 extend to the outside of the primary processing box 3. Three equidistant synchronous toothed belts 23 are arranged between them. A second gear 24, which meshes with the synchronous toothed belt 23, is fixedly installed on the outer side of the rotating rod 22. A third motor 25 is fixedly installed on the outer side of the primary processing box 3. The output end of the third motor 25 is fixedly connected to one end of an adjacent rotating rod 22, so that when the third motor 25 runs, it can drive the corresponding rotating rod 22 to rotate. The second gear 24 on this rotating rod 22, in conjunction with the second gear 24 on another rotating rod 22, drives the three synchronous toothed belts 23 to rotate synchronously. An installation groove is provided on the outer side of the inclined plate 6 for installing the synchronous toothed belts 23 and the second gear 24. The outer side of the synchronous toothed belt 23 is connected to the conveyor belt. The inner side of the conveyor belt 10 is fixedly connected, allowing the synchronous toothed belt 23 to drive the conveyor belt 10 to rotate and move between the outer side of the inclined plate 6 and the two positioning plates 21. Utilizing the property that grease has a lower density than water, the grease floating on the water surface is conveyed upwards. A collection box 39 is provided below the right end of the inclined plate 6, and a scraper 26 is provided on the top of the collection box 39. The scraper 26 is fixedly installed inside the primary treatment box 3, and the outer side of the scraper 26 contacts the outer side of the conveyor belt 10, so that the scraper 26 scrapes off the grease on the conveyor belt 10 and puts it into the collection box 39 for temporary storage. A storage valve is fixedly installed on the outer side of the drain valve between the primary treatment box 3 and the pretreatment box 2. The flocculant injection cylinder 27 allows flocculant to be injected into the drain valve, promoting the flocculation and sedimentation of remaining fine suspended particles in the wastewater. An opening is provided on the outside of the primary treatment tank 3 for the storage box 39 to be inserted, facilitating the removal of the storage box 39 from the primary treatment tank 3 by staff for cleaning grease. A control panel 37 is fixedly installed on the outside of the primary treatment tank 3, and a liquid level monitor 38 is fixedly installed on the top of the primary treatment tank 3. The liquid level monitor 38 detects the liquid level in the primary treatment tank 3, and the control panel 37 controls the drain valve to prevent the liquid level in the primary treatment tank 3 from exceeding the inclined plate 6.

[0033] Example 3: Please refer to Figure 2 , Figure 7 and Figure 8This embodiment further illustrates other embodiments. The fixed-dismantling mechanism shown in the figure includes an insert block 11 fixedly installed at the bottom of the pretreatment box 2, the first-stage treatment box 3, the second-stage treatment box 4, and the deep treatment box 5. The insert block 11 can improve the convenience of installation of the pretreatment box 2, the first-stage treatment box 3, the second-stage treatment box 4, and the deep treatment box 5. The fixed-dismantling mechanism also includes a locking block 28 disposed on both sides of the insert block 11. The outer side of the insert block 11 has a locking groove for the locking block 28 to be inserted and limited, and the inner side of the device base 1 has a cavity for the locking block 28 to move. Four equidistant opposite screws 29 are rotatably installed on the inner side of the device base 1. The four opposite screws 29 are respectively located below the four insert blocks 11. The locking blocks 28 on both sides of the insert block 11 are threaded. The optical shaft for limiting the sliding of the locking blocks 28 is fixedly installed in the cavity of the device base 1 on the threads at both ends of the adjacent counter-rotating screws 29. When the counter-rotating screws 29 rotate, they can drive the two locking blocks 28 to move closer to or away from the insertion block 11. A sprocket 30 is fixedly installed on the outside of the counter-rotating screws 29, and a chain 31 is rotatably installed between the four sprockets 30. Adjustment slots are opened at both ends of the counter-rotating screws 29. The operator can insert the adjustment wrench into the adjustment slot of the counter-rotating screw 29 to rotate the counter-rotating screw 29. The four counter-rotating screws 29 can be rotated synchronously through the cooperation of the sprockets 30 and the chain 31, so that the locking blocks 28 move away from the insertion block 11, thereby realizing the synchronous disassembly of the pretreatment box 2, the first-stage treatment box 3, the second-stage treatment box 4 and the deep treatment box 5.

[0034] Working principle: First, the operator places the pretreatment box 2, primary treatment box 3, secondary treatment box 4, and deep treatment box 5 sequentially on the device base 1. Rotating any one of the counter-rotating screws 29 causes the chain 31 to rotate via the sprocket 30 on its outer side. This chain 31 then drives the other three counter-rotating screws 29 to rotate synchronously. The four counter-rotating screws 29 then move their corresponding two locking blocks 28 closer together along the outer side of the optical axis and insert them into the slots of the bottom insert blocks 11 of the pretreatment box 2, primary treatment box 3, secondary treatment box 4, and deep treatment box 5, achieving rapid assembly of these components. Then, the operator pulls the folding handle 34 to open the device base... The casters 35 at the bottom of the base 1 move along the ground, moving the entire device to the sewage discharge area of ​​the construction site. The sewage discharge pipe is then connected to the pretreatment tank 2, and the sewage is injected into the pretreatment tank 2. The vibrating screen 40 inside the pretreatment tank 2 filters out particulate impurities, trapping them within the screen. The filtered sewage then enters the centrifuge drum 9 through the guide hopper 15. At this time, the second motor 18 drives the first gear 19 to rotate, causing the centrifuge drum 9 to rotate at high speed via the gear ring 17. Under centrifugal force, denser sediment particles quickly settle to the bottom of the centrifuge drum 9. The pretreated sewage then enters the primary treatment tank 3 through the first drain valve, in conjunction with liquid level monitoring. Device 38 injects wastewater to the middle position of the inclined plate 6. At this time, the third motor 25 runs, driving the corresponding rotating rod 22 to rotate. The second gear 24 on the rotating rod 22, in conjunction with the second gear 24 on another rotating rod 22, drives the three synchronous toothed belts 23 to rotate synchronously. The synchronous toothed belts 23 drive the conveyor belt 10 to rotate and move along the outer side of the inclined plate 6 between the two positioning plates 21. Taking advantage of the fact that the density of grease is less than that of water, the grease floating on the water surface is transported upward. As the conveyor belt 10 moves, the scraper 26 scrapes the grease on the conveyor belt 10 downward and puts it into the collection box 39, so that the collection box 39 temporarily stores the grease. Flocculant is injected into the wastewater through the injection cylinder 27 to treat the fine particles in the wastewater. Small particles are processed, and then the wastewater in the primary treatment tank 3 enters the secondary treatment tank 4 through the second drain valve. The activated carbon and composite adsorption material in the adsorption frame 7 adsorb organic pollutants and pigments in the wastewater and remove some dissolved ionic pollutants. Finally, the water in the secondary treatment tank 4 enters the deep treatment tank 5 through the third drain valve. The wastewater passes through the inlet cylinder 32 and is oxidized by the ultraviolet lamp 33. It then enters the reverse osmosis membrane module 8, where the reverse osmosis membrane module 8 retains the trace pollutants, achieving deep purification of the wastewater. This achieves efficient wastewater treatment. The overall structure is designed as an integrated unit, which is convenient for use on construction sites and improves the flexibility and convenience of wastewater treatment.
