Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a construction wastewater isolation, sedimentation and purification device. Background Technology

[0002] Construction sites generate a large amount of construction wastewater, which often contains a lot of mud, sand, gravel, and oil pollutants. If discharged directly into rivers or surface water, it will cause pollution and harm to the environment. Traditional sedimentation tanks are no longer suitable for discharge requirements. If multi-stage treatment devices are used, they are costly and located in fixed locations, requiring long pipelines to transport the wastewater, which is not very practical. Therefore, it is necessary to develop a new type of construction wastewater treatment device that can quickly and easily treat and purify the wastewater. Utility Model Content

[0003] To address the aforementioned issues, this utility model discloses a construction wastewater isolation sedimentation and purification device, which includes processes such as filtration, oil removal, reaction, and slag removal. Moreover, it adopts a mobile structure, enabling simple, convenient, timely, and rapid wastewater treatment with low treatment costs and high efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A construction wastewater isolation sedimentation and purification device includes a vehicle body with casters at the bottom. The vehicle body is divided into a filtration and oil removal zone, a reaction zone, and a purification zone. The filtration and oil removal zone has a filter plate in the middle, and a drain pipe on one side of the filter plate connects to the space below the filter plate. A treatment hood is located above the filter plate, and a movable oil-absorbing screen is vertically inserted inside the treatment hood. The reaction zone is located between the filtration and oil removal zone and the purification zone. A dosing port is located above the reaction zone, and a movable filter screen is located above the purification zone, connecting to the outlet of the reaction zone. A purification layer is located below the purification zone. The filtration and oil removal zone, the reaction zone, and the purification zone all have outlets on their lower sides.

[0006] As an improvement of this utility model, the universal wheel is provided with a brake pad on its side.

[0007] As an improvement of this utility model, the number of oil-absorbing nets is 3-4.

[0008] As an improvement of this utility model, the outer frame of the oil absorption net is inserted into the vertical groove on the inner wall of the treatment hood.

[0009] As an improvement of this utility model, the dosing port is provided with a scale.

[0010] As an improvement of this utility model, the outer frame of the movable filter screen is inserted into the sliding groove above the purification zone.

[0011] As an improvement of this utility model, the purification layer is filled with hydrogel material.

[0012] As an improvement of this utility model, a control valve is provided at the outlet.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) Construction wastewater directly enters the cavity below the filter plate, and the water level slowly rises before flowing to the oil suction net, thus eliminating the defect of the filter plate being blocked in the sedimentation tank in the past.

[0015] (2) The filtered wastewater is initially absorbed by the oil suction net, which helps to improve the oil removal effect in the subsequent process;

[0016] (3) Multiple oil suction screens are installed, which can be taken out and replaced or processed in turn to ensure the effect;

[0017] (4) The reaction zone reacts directly without a stirrer, which overcomes the contradiction between stirring and sedimentation. The chemical is added from the top, and the particulate matter after the reaction sinks to the bottom while the flocculent matter floats to the top. Finally, it flows out from the outlet and is intercepted by the movable filter screen, ensuring that the water after the reaction flows into the purification zone.

[0018] (5) Water flows out after passing through the hydrogel material inside the purification area, meeting the discharge requirements;

[0019] (6) The whole device adopts a mobile structure, which is convenient, flexible and efficient. Attached Figure Description

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] As shown in the figure, the construction wastewater isolation sedimentation and purification device of this utility model includes a vehicle body 1. The bottom of the vehicle body 1 is equipped with casters 2. The interior of the vehicle body 1 is divided into a filtration and oil removal zone 3, a reaction zone 4, and a purification zone 5. The filtration and oil removal zone 3 is provided with a filter plate 6 in the middle. A drain pipe 7 is provided on one side of the filter plate 6 to connect to the space below the filter plate. A treatment cover 8 is provided above the filter plate 6. A movable oil-absorbing screen 9 is vertically inserted inside the treatment cover 8. The reaction zone 4 is located between the filtration and oil removal zone 3 and the purification zone 5. A dosing port 10 is provided above the reaction zone 4. A movable filter screen 11 is provided on the upper side of the purification zone 5 to connect to the water outlet 12 of the reaction zone. A purification layer 13 is provided below the purification zone 5. An outlet 14 is provided on the lower side of the filtration and oil removal zone 3, the reaction zone 4, and the purification zone 5.

[0026] The construction wastewater isolation sedimentation and purification device of this utility model has casters 2 at the bottom of the vehicle body 1, which can be quickly moved to the place where drainage is needed, which is convenient, flexible and efficient; brake pads 15 are provided on the side of the casters 2, which can stop and fix it when needed.

[0027] The construction wastewater isolation sedimentation and purification device of this utility model allows construction wastewater to enter the cavity below the filter plate 6 from the drain pipe 7. After the water level slowly rises, it flows towards the oil suction net 9, eliminating the defect of filter plates being blocked in the sedimentation tank in the past. The filtered wastewater undergoes preliminary oil absorption through the oil suction net 9, which is equivalent to pretreatment and is conducive to the oil removal effect in the reaction zone 4. The oil suction net 9 is set with 3-4 layers, which can be removed and replaced or treated in turn to ensure the effect. The water after oil absorption enters the reaction zone 4, and the chemical is added from the top. The particulate matter after reaction sinks to the bottom, while the flocculent matter floats to the top. Finally, it flows out from the outlet 12 and is intercepted by the movable filter net 11 to ensure that the water after reaction flows into the purification zone 5. The reaction zone 4 of this utility model does not have a stirrer. The chemical reaction is carried out directly, which overcomes the contradiction between stirring and sedimentation. Finally, the water flows out after passing through the hydrogel material (purification layer 13) inside the purification zone, which meets the discharge requirements.

[0028] The outer frame of the oil-absorbing mesh 9 of this utility model is inserted into the vertical groove on the inner wall of the treatment cover 8, and can be removed or inserted separately for easy replacement or maintenance.

[0029] Similarly, the outer frame 17 of the movable filter screen is inserted into the slide groove 18 above the side of the purification zone 5. There is a handle 19 on the top of the outer frame 17 of the filter screen. By grasping the handle 19 and lifting it upward, the outer frame 17 of the movable filter screen can be taken out for replacement or disposal. It is convenient and practical and suitable for use on construction sites.

[0030] This invention features a scale 16 at the dosing port 10 to control the amount of medicine added.

[0031] This utility model has control valves 20 at several outlets 14, which can be used for sludge discharge, sewage discharge or drainage.

[0032] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
