[0002] The main sources of wastewater from construction projects are watering of formwork, masonry blocks, terrazzo, waterjet cutting, vehicle washing at gate exits, and sanitation management. Therefore, the volume of wastewater generated by construction projects is enormous. If it is not treated and recycled, it will lead to significant water waste and adverse environmental impacts. Furthermore, the wastewater contains impurities such as silt, which can easily cause blockages in discharge pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a wastewater recycling and treatment device for construction projects, including: a recycling tank 1, a flocculation chamber 4 is provided on one side of the inside of the recycling tank 1, a first filter chamber 6 is provided on one side of the flocculation chamber 4, a second filter chamber 7 is provided on one side of the first filter chamber 6, and a third filter chamber 8 is provided on one side of the second filter chamber 7. Filter plates 9 are provided between the first filter chamber 6 and the second filter chamber 7, as well as between the second filter chamber 7 and the third filter chamber 8. A water outlet pipe 3 is connected to the surface of the third filter chamber 8, and a water inlet pipe 2 is connected to the surface of the recycling tank 1.

[0023] Inside the flocculation chamber 4, a lifting pipe 5 is installed. A second lifting pump 504 is installed on the surface of the lifting pipe 5. A discharge pipe 501 is connected to one side of the lifting pipe 5, and a connecting pipe 502 is connected to the surface of the discharge pipe 501. A first lifting pump 503 is installed on the surface of the discharge pipe 501.

[0024] Specifically, through the setting of the connecting pipe 502, the lower end of the connecting pipe 502 is connected to the interior of the recycling tank 1, the upper end of the connecting pipe 502 is connected to the discharge pipe 501, the discharge pipe 501 is connected to the connecting pipe 502, and the discharge pipe 501 is not connected to the lifting pipe 5. Using the connecting pipe 502 and the discharge pipe 501, the wastewater in the recycling tank 1 is pumped into the flocculation chamber 4, and then the wastewater is pumped into the filter chamber 6 through the lifting pipe 5.

[0025] Filter chamber 1 (6), filter chamber 2 (7), and filter chamber 3 (8) are arranged in a fan shape on one side of the recycling bin 1. The bottom of filter chamber 1 (6) faces filter chamber 2 (7), and the bottom of filter chamber 2 (7) slopes towards filter chamber 3 (8).

[0026] Specifically, filter plates 9 are installed between filter chamber 6, filter chamber 7, and filter chamber 8. These filter plates 9 sequentially guide wastewater from filter chamber 6 to filter chamber 7 and finally to filter chamber 8, performing multi-stage filtration to improve wastewater treatment efficiency.

[0027] An electric pump 10 is installed on the inner wall of the recycling bin 1, and a conveying pipe 11 is connected to one side of the electric pump 10. A diverter 12 is installed on the front side of the electric pump 10, and an injection pipe 13 is connected to the output end of the diverter 12. The conveying pipe 11 and the diverter 12 are connected to each other.

[0028] Specifically, through the setting of the conveying pipe 11, the conveying pipe 11 is connected to the injection pipe 13 through the diverter 12. The conveying pipe 11 can convey the chemical treatment agent. The diverter 12 is used to divert the chemical treatment agent through the injection pipe 13 and inject it into the recovery tank 1 to treat the wastewater recovered in the recovery tank 1.

[0029] The working principle of this utility model is as follows: When using this utility model, the inlet pipe 2 discharges construction wastewater into the recycling tank 1. The electric pump 10, in conjunction with the delivery pipe 11, inputs the chemical treatment agent into the recycling tank 1. The distributor 12 diverts the chemical treatment agent through the injection pipe 13 into the recycling tank 1. Next, the lift pump 503 uses the wastewater treated with the chemical treatment agent in the recycling tank 1 to be drawn into the flocculation chamber 4 through the connecting pipe 502. After being drawn in through the connecting pipe 502, it is discharged into the flocculation chamber 4 through the discharge pipe 501. After the flocculant settles, the wastewater is then pumped out through the lift pump 503. Pump 2 504 pumps the wastewater from flocculation chamber 4 into the filter chamber. After the wastewater enters filter chamber 1 6, because the bottom of filter chamber 1 6 is inclined towards filter chamber 2 7 and is higher than filter chamber 2 7, the wastewater in filter chamber 1 6 will flow into filter chamber 2 7 after being filtered by filter plate 9. Similarly, the bottom of filter chamber 2 7 is inclined towards filter chamber 3 8, and the wastewater in filter chamber 2 7 flows into filter chamber 3 8. At the same time, it is also filtered and intercepted by a set of filter plates 9. Finally, a water outlet pipe 3 is connected to one side of the filter chamber, and the treated wastewater is discharged through the water outlet pipe 3.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
