Description

Technical Field

[0001] This utility model relates to the field of construction wastewater treatment, and in particular to a modular construction wastewater treatment device. Background Technology

[0002] Tunnels, excavators, and grouters are crucial components of large-scale engineering projects, such as water conservancy and hydropower projects, and tunnel engineering. These operations typically traverse areas rich in groundwater with highly complex geological conditions. The treatment of water inrushes, seepage, and wastewater generated during tunnel construction is extremely challenging. The characteristic pollutants in construction wastewater are suspended solids and petroleum-based substances. Direct discharge into local rivers without treatment will severely impact the local surface water environment and may even damage the soil and groundwater. Existing treatment methods often require large land areas and the construction of new treatment ponds, resulting in high construction and operational difficulties and economic costs. Common construction wastewater treatment methods include natural sedimentation, flocculation sedimentation, and mechanical treatment. These methods share a common characteristic: they require significant civil engineering work. Furthermore, since wastewater treatment in many projects is only a temporary measure and needs to be dismantled later, this not only occupies a large area but also results in substantial waste.

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings and defects mentioned in the background art above, and to provide a modular construction wastewater treatment device that is easy to assemble, has low construction difficulty, and low cost. To solve the above technical problem, the technical solution proposed by this utility model is as follows:

[0004] A modular construction wastewater treatment device includes: two sets of modular side plates arranged opposite each other, each side plate including a base plate and a vertical plate connected to the base plate, the edges of the base plate and the vertical plate having multiple connecting holes, the vertical plate having a ring of insertion grooves near its edge, the two sets of modular side plates being detachably connected by bolts through the corresponding connecting holes of the two base plates to form a U-shaped slotted structure, and a rubber strip being sandwiched between the two opposing base plates;

[0005] The insert plate is provided with water inlet and outlet holes, and the insert plate is inserted into the insertion slot and detachably connected to two sets of splicing side plates.

[0007] It also includes a top plate, which covers the U-shaped slotted structure and is detachably connected to the slotted cross brace.

[0008] In one embodiment, the two sets of splicing side panels include multiple pairs of splicing side panels, which are combined and spliced ​​into different shapes. Adjacent splicing side panels are detachably connected by bolts passing through the corresponding connection holes of the vertical plates. Rubber strips are sandwiched between adjacent vertical plates, and there are at least two insert plates.

[0009] In one embodiment, the inlet and outlet water holes are connected by a flange structure, and a sealing ring is provided in the middle of the flange structure.

[0024] Please see Figures 1-6 A modular construction wastewater treatment device 1 includes: two sets of modular side plates 2, insert plates 3, and a top plate 4 arranged opposite to each other. The modular side plates 2, insert plates 3, and top plate 4 are all detachable and connectable. The top plate 4 is set according to actual needs. The setting of the top plate 4 can facilitate workers to go up for maintenance, and at the same time prevent rainwater from flowing into the device when it rains.

[0025] Specifically, the splicing side panel 2 includes a base plate 2.2 and a vertical plate 2.1 connected to the base plate 2.2. Multiple connecting holes 2.3 are provided along the edges of both the base plate 2.2 and the vertical plate 2.1. A ring of insertion grooves 2.5 is provided near the edge of the vertical plate 2.1. The two sets of splicing side panels 2 are detachably connected by bolts 2.4 through the corresponding connecting holes 2.3 of the two base plates 2.2, forming a U-shaped slotted structure. A rubber strip 2.6 is sandwiched between the two opposing base plates 2.2 during splicing. An insert plate 3 is inserted into the insertion grooves 2.5 and detachably connected to the two sets of splicing side panels 2. The insert plate 3 is provided with inlet and outlet water holes 3.1 for wastewater inflow and outflow. Preferably, the inlet and outlet water holes 3.1 are located near the top of the insert plate 3 to facilitate the outflow of upper-layer water. Preferably, the two sets of splicing side panels 2 include multiple pairs of splicing side panels 2, which are combined and spliced ​​into different shapes, such as long strips or L-shapes (e.g.,...). Figure 6(As shown). Adjacent splicing side plates 2 are detachably connected to the vertical plates 2.1 via bolt pairs 2.4 through the corresponding connecting holes 2.3. A rubber strip 2.6 is sandwiched between adjacent vertical plates 2.1. There are at least two insert plates 3. Insert plates are provided at both ends of the spliced ​​construction wastewater treatment device 1, and the number of insert plates 3 in the middle is set according to actual needs. The insert plates 3 can divide the entire device into different wastewater treatment spaces. Different wastewater treatment agents can be added to different wastewater treatment spaces. If it is necessary to precipitate wastewater with high SS content, the wastewater treatment space can be divided into 3 sections. Oxalic acid and PAC are added to the first section, and PAM is added to the other two sections. When treating wastewater with low SS content, no chemicals need to be added. In the spliced ​​construction wastewater treatment device 1, suspended particles settle, and the upper clear water flows to the next wastewater treatment space through the inlet and outlet holes 3.1 until the water quality meets the requirements and is discharged through the inlet and outlet holes 3.1 of the last wastewater treatment space. Preferably, the inlet and outlet holes 3.1 are connected by a flange structure, and a sealing ring is provided in the middle of the flange structure.

[0026] Preferably, in one embodiment, when a top plate 4 is required, the top of the insert plate 3 is provided with a cross brace 3.2, which can increase the pressure-bearing capacity of the wastewater treatment device and prevent it from splitting to both sides. At the same time, the cross brace facilitates the installation of the insert plate 3. The cross brace 3.2 is provided with a slot 3.3. The top plate 4 is covered on the U-shaped slotted structure and is detachably connected to the slot 3.3 of the cross brace 3.2. The slot 3.3 can fix the top plate 4 on the U-shaped slotted structure and prevent it from slipping off due to external forces.

[0027] Preferably, in one embodiment, a sludge discharge hole 2.7 is provided near the bottom of the vertical plate 2.1. The resulting suspended particulate matter is discharged through the sludge discharge hole 2.7.

[0028] Preferably, the splicing side panel 2, insert plate 3 and top plate 4 are all made of fiberglass or stainless steel.

[0029] The specific usage process of the above-mentioned modular construction wastewater treatment device 1 is as follows:

[0030] Before wastewater is generated in a certain project, the spliced ​​side panels 2, insert plates 3, and top plate 4 are transported to the vicinity of the project site. A channel is dug in the ground at the wastewater treatment area to accommodate the spliced ​​construction wastewater treatment device 1. The bottom plates 2.2 of opposite sets of spliced ​​side panels 2 are connected one by one using bolt pairs 2.4. Then, the vertical plates 2.1 of adjacent spliced ​​side panels 2 are connected using bolt pairs 2.4. The insert plates 3 are inserted into the insertion slots 2.5 respectively, forming multiple treatment spaces that can hold wastewater. Finally, the top plate 4 is placed on the slots 3.3 of the cross brace 3.2. Different structural styles can be arranged according to the existing terrain and land use conditions of the project. External pipes are connected to the inlet and outlet holes 3.1 through a flange structure with a rubber ring in the middle to prevent water leakage.

[0031] After wastewater is generated, it enters the treatment space of the modular construction wastewater treatment device 1. Under the action of gravity, suspended particles in the wastewater settle and are discharged through the sludge discharge hole 2.7. The supernatant clear water flows from the first treatment space to the last treatment space through the inlet and outlet holes 3.1 until the water quality meets the requirements, and then it is discharged through the inlet and outlet holes 3.1 of the last wastewater treatment space. The generated suspended particles settle and are discharged through the sludge discharge hole 2.7, and finally transported for off-site treatment. After the wastewater treatment of one project is completed, the assembled device can be disassembled, transported to the next project, and reused according to the above steps.

[0032] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
