[0002] Building sewage treatment is an important part of modern urban environmental management, which involves the treatment of sewage generated by buildings (such as domestic sewage, kitchen sewage, washing water, etc.) to reduce pollution to the environment and protect water resources.

[0004] However, although the existing technology can disinfect the purified building sewage at high temperature and can absorb iron-containing substances in the water body through magnetic force, building sewage usually contains different metal substances, including copper and zinc that cannot be attracted by magnetic force under normal conditions.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 4 As shown, a construction sewage treatment device described in an embodiment of the present invention includes a bearing portion, a flocculation mechanism and an aeration mechanism.

[0023] The bearing part includes a reaction pool 1 and a bearing plate 7. The bearing plate 7 is fixedly installed at the bottom of the reaction pool 1. The reaction pool 1 is used to accommodate water resources that need to be treated. The bearing plate 7 is made of insulating material, and ceramic is selected in this embodiment.

[0024] The flocculation mechanism includes an electrode plate 2 and a terminal 10. The electrode plate 2 is divided into two types, namely a cathode plate and an anode plate. The electrode plate 2 is fixedly mounted on the upper end surface of a supporting plate 7. The supporting plate 7 is a mounting and supporting position for the electrode plate 2, and the electrode plate 2 extends into the liquid material.

[0025] The terminal 10 is electrically connected to the electrode plate 2 to facilitate connection with an external power source. A plurality of electrode plates 2 are provided, and two adjacent electrode plates 2 are parallel to each other. After power is turned on, an electrolysis reaction occurs. When an electric field is applied to the liquid, the particles and colloidal particles suspended in the water are charged by the electric field. Particles with the same charge repel each other, and particles with different charges attract each other, causing the charged particles to gradually gather into groups under the action of the electric field to complete flocculation.

[0026] The aeration mechanism includes a connecting tube 6 and an aeration pipe 3. The connecting tube 6 is arranged between two adjacent electrode plates 2. One end of the aeration pipe 3 is connected to the output end of an external aeration pump, and the other end of the aeration pipe 3 is connected to the inner cavity of the connecting tube 6. The external aeration pump discharges oxygen into the inner cavity of the connecting tube 6 through the aeration pipe 3.

[0027] In order to facilitate the separation of metal from water, an exhaust hole is provided on the outer wall of the connecting tube 6. When the aeration pump introduces oxygen, the oxygen is discharged through the exhaust hole, thereby reacting with the metal substances in the water. During the electrolysis reaction, OH ions are generated in the water, which combine with the metal ions to form insoluble substances, thereby precipitating. Compared with a Chinese patent with publication number CN117303629A, a drinking water purification device and a purification method thereof, the method of adsorbing iron impurities through magnetic suction holes can effectively improve the efficiency of water treatment. Compared with the magnetic force that can only attract iron-containing particles, different metals can be removed by oxidizing the metal objects and then electrolyzing and flocculating, thereby effectively improving the treatment range.

[0028] During electrolysis, floccules are generated in the reaction tank 1, which are easily attached to the outer wall of the electrode plate 2, thereby affecting the contact between the electrode plate 2 and the water body. The exhaust holes are inclined toward the outer wall of the electrode plate 2, so that during aeration, the gas is controlled to blow toward the electrode plate 2, driving the flow of nearby water, thereby reducing the probability of floccules attaching to the outer wall of the electrode plate 2, and maintaining the contact between the electrode plate 2 and the water body. The introduction of oxygen can not only improve the flocculation efficiency, but also reduce the probability of floccules attaching to the outer wall of the electrode plate 2, thereby achieving the cleaning of the electrode plate 2, and maintaining the efficiency of water treatment through mutual cooperation.

[0029] A containing box 4 is fixedly mounted on the outer wall of the reaction pool 1 , and a control plug 9 is slidably mounted on the inner wall of the containing box 4 . The outer wall of the control plug 9 is made of rubber and is slidably fitted with the inner wall of the containing box 4 .

[0030] A transmission rod 8 is fixedly installed on one side of the control plug 9, and the other end of the transmission rod 8 extends to the interior of the reaction pool 1 and is fixedly connected to the outer wall of the connecting tube 6. The sliding adjustment control plug 9 drives the connecting tube 6 to slide between two adjacent electrode plates 2 through the transmission rod 8.

[0031] The cleaning mechanism includes a containing box 4 and an elastic strip 11. The elastic strip 11 is arranged on the outer wall of the connecting tube 6. The sliding of the connecting tube 6 is controlled by the air pressure in the inner cavity of the containing box 4. The elastic strip 11 is made of rubber and fits the outer wall of the electrode plate 2. The connecting tube 6 slides to drive the elastic strip 11 to slide synchronously, thereby erasing the flocculants on the outer wall of the electrode plate 2. After the flocculants are erased, the oxygen discharged by the connecting tube 6 controls the flow of the water body, thereby preventing the flocculants from adhering again. The two complement each other to prevent the flocculants from adhering and maintain the normal operation of the electric flocculation.

[0032] In order to facilitate the sliding of the control connecting tube 6, a control cylinder 5 is fixedly installed on the outer wall of the accommodating box 4. The movable end of the control cylinder 5 extends to the inner cavity of the accommodating box 4 and is fixedly connected to the outer wall of the control plug 9. The control cylinder 5 is a common hydraulic cylinder. The control plug 9 is driven to slide by the control cylinder 5, and then the elastic strip 11 and the connecting tube 6 are driven to slide synchronously, so as to maintain normal contact between the electrode plate 2 and the water body.

[0033] In this embodiment, the connecting tube 6 is moved by controlling the cylinder 5 to change the position of oxygen introduction, so that the water in the reaction tank 1 is evenly contacted with oxygen, thereby promoting electro-flocculation and improving work efficiency by improving oxidation efficiency.

[0034] A sliding plug 14 is elastically mounted on the inner wall of the connecting tube 6, and the outer wall of the sliding plug 14 slides in contact with the inner wall of the connecting tube 6. A spring is provided at the bottom of the sliding plug 14, and the outer wall of the spring is fixedly connected to the inner wall of the connecting tube 6. After oxygen is introduced into the inner cavity of the connecting tube 6, the air pressure in the inner cavity of the connecting tube 6 increases, thereby pushing the sliding plug 14 to slide.

[0035] The upper end surface of the sliding plug 14 is fixedly mounted with a mounting frame 13 , and the outer wall of the mounting frame 13 is fixedly mounted with a blocking ring 12 . The outer wall of the blocking ring 12 is slidingly fitted with the inner wall of the connecting tube 6 , and the sliding adjustment sliding plug 14 controls the sliding of the blocking ring 12 through the mounting frame 13 .

[0036] In this embodiment, a plurality of exhaust holes are evenly arranged along the axis of the connecting tube 6. Before oxygen is introduced, the sealing ring 12 is flush with the exhaust holes on the outer wall of the connecting tube 6. At this time, the exhaust holes are blocked by the sealing ring 12 to prevent water from entering the inner cavity of the connecting tube 6. When oxygen is introduced, the sliding plug 14 slides until the sealing ring 12 is separated from the exhaust holes. At this time, the plurality of exhaust holes on the outer wall of the connecting tube 6 are synchronously connected, so that oxygen is evenly discharged from the outer wall of the connecting tube 6, thereby facilitating the contact between the water and the oxygen discharged from the exhaust holes at different positions, thereby increasing the contact area between the water and the oxygen.

[0037] A guide plate 30 is fixedly installed on the inner wall of the reaction tank 1. The inner wall of the guide plate 30 is an arc-shaped structure and faces the connecting tube 6. When the connecting tube 6 discharges oxygen, the water flows synchronously, and then a part of the water flows toward the guide plate 30 and impacts the arc-shaped surface of the guide plate 30. The arc-shaped surface of the guide plate 30 faces upward, so that the water can flow upward after the impact, thereby achieving up and down stirring of the water, facilitating the contact between the water at different positions and the electrode plate 2, and further improving the efficiency of electric flocculation.

[0038] Embodiment 2: Figures 5 to 11 As shown in Comparative Example 1, another embodiment of the present invention is: The upper end surface of the connecting tube 6 is slidably mounted with a collecting bucket 17 via a telescopic rod. During the sliding process of the connecting tube 6 , the collecting bucket 17 is driven to slide synchronously, so that water can enter the inner cavity of the collecting bucket 17 .

[0039] The bottom of the collecting hopper 17 is a mesh plate, and an opening is provided on one side of the collecting hopper 17, wherein the opening of the collecting hopper 17 faces the guide plate 30, and the water body after impacting the guide plate 30 enters the interior of the collecting hopper 17 by inertia, preventing the flocculants from settling and gathering at the bottom of the reaction tank 1.

[0040] A filter plate 21 is detachably mounted on one side of the collecting hopper 17 away from the opening. The filter plate 21 is used to filter floccules in the water body. After the water flows through the filter plate 21 , the floccules are filtered by the filter plate 21 and are collected in the inner cavity of the collecting hopper 17 .

[0041] A blocking plate 22 is fixedly installed on the inner wall of the collecting bucket 17. The blocking plate 22 is tilted and faces the filter plate 21. When the collecting bucket 17 slides forward, water enters the inner cavity of the collecting bucket 17 due to inertia. When the collecting bucket 17 slides backward, the blocking plate 22 blocks the water and prevents the flocculants from sliding out of the inner cavity of the collecting bucket 17.

[0042] An arc plate 16 is fixedly installed at the opening of the collecting bucket 17. There are multiple arc plates 16, and a gap is reserved between two adjacent arc plates 16 for materials to pass through. The arc plates 16 are made of elastic material. When the collecting bucket 17 moves forward, the water containing flocculants impacts the arc plates 16, so that the two arc plates 16 move away from each other, so that the water containing flocculants can enter the inner cavity of the collecting bucket 17. When the collecting bucket 17 moves backward, the water inside the collecting bucket 17 is inertially impacted by the arc plates 16, so that the two arc plates 16 approach each other until they fit together, thereby closing the opening of the collecting bucket 17 and preventing the flocculants from flowing out of the inner cavity of the collecting bucket 17.

[0043] The outer wall of the arc plate 16 is fixedly mounted with a drainage plate 15 , and the outer wall of the drainage plate 15 is inclined. In a top view, the drainage plate 15 is trumpet-shaped, which facilitates the gathering of water into the inner cavity of the collecting bucket 17 when the collecting bucket 17 moves forward.

[0044] In this embodiment, flocculants are collected by collecting bucket 17, thereby reducing the flocculant content in the water body in reaction tank 1. High concentration of flocculants can change the distribution and intensity of the electric field, so that the uniformity of the electric field in the liquid is affected. Collecting flocculants by collecting bucket 17 can prevent electric field interference and improve the efficiency of electric flocculation. At the same time, excessive flocculant content inhibits the charge interaction between particles, thereby reducing the rate and efficiency of particle aggregation. After collecting the flocculants, the charge influence between particles can be reduced as much as possible, further improving the flocculation efficiency.

[0045] The capturing mechanism absorbs the flocculants in the reaction tank 1 by changing the air pressure in the inner cavity of the containing box 4. The capturing mechanism includes a transfer box 25 and an air intake pipe 31. One end of the air intake pipe 31 is fixedly connected to the outer wall of the containing box 4. A one-way valve is arranged in the air intake pipe 31. The air intake pipe 31 is used to control the gas entering the containing box 4. An exhaust pipe is arranged on the outer wall of the containing box 4. A one-way valve is arranged in the exhaust pipe. The flow directions of the two one-way valves are opposite. When the control plug 9 slides back and forth along the inner wall of the containing box 4, the gas enters the inner cavity of the containing box 4 through the air intake pipe 31 and is then discharged through the exhaust pipe.

[0046] The transfer box 25 is arranged above the reaction tank 1, and the other end of the suction pipe 31 is connected to the inner cavity of the transfer box 25. When the control plug 9 pushes the transmission rod 8, the air pressure on the side of the control plug 9 away from the transmission rod 8 decreases, thereby causing the air pressure on the inner wall of the transfer box 25 to decrease, and then generate suction at the absorption tube 20, which is used to absorb flocculants when the collecting bucket 17 is raised.

[0047] A support frame 23 is fixedly mounted on the side wall of the reaction pool 1 , and a lifting cylinder 24 is fixedly mounted on the outer wall of the support frame 23 . The lifting cylinder 24 is a common electric telescopic rod, and the support frame 23 provides an installation and force position for the lifting cylinder 24 .

[0048] A connecting frame 18 is fixedly installed on the movable end of the lifting cylinder 24, and a guide roller 19 is fixedly installed on the side wall of the connecting frame 18. A groove for the guide roller 19 to slide is provided on the side wall of the collecting bucket 17. The connecting frame 18 is adjusted by lifting and lowering, and the collecting bucket 17 is driven to lift and lower through the guide roller 19.

[0049] By cooperating with the groove on the outer wall of the collecting bucket 17, the raising and lowering of the collecting bucket 17 can be controlled during the sliding of the connecting tube 6. At this time, the telescopic rod connecting the collecting bucket 17 and the connecting tube 6 is extended to maintain the connection between the connecting tube 6 and the collecting bucket 17. In addition, in order to prevent the collecting bucket 17 from tilting during the raising and lowering of the collecting bucket 17, at least three guide rollers 19 are provided. In this embodiment, four guide rollers 19 are provided, which are symmetrically distributed on the side walls of the collecting bucket 17.

[0050] As the floccules inside the collecting hopper 17 are collected, the thickness of the floccules gradually increases. In order to prevent the floccules from overflowing during the sliding process of the collecting hopper 17, the floccules in the collecting hopper 17 need to be cleared. A transfer box 25 is fixedly installed on the outer wall of the carrier 23. An absorption tube 20 is fixedly installed on the outer wall of the transfer box 25. The other end of the absorption tube 20 extends into the collecting hopper 17, and the transfer box 25 is connected to the external negative pressure chamber, so that negative pressure is generated in the inner cavity of the transfer box 25, and then the collecting hopper 17 is filled with water. It rises and is lifted until the bottom surface of the collecting bucket 17 is separated from the liquid surface inside the reaction tank 1. At this time, the water in the collecting bucket 17 is discharged through the mesh plate on the bottom surface of the collecting bucket 17, thereby retaining the water-containing flocs inside the collecting bucket 17, and then the water-containing flocs are absorbed by the absorption tube 20 until the flocs enter the inner cavity of the transfer box 25, thereby reducing the storage amount of flocs in the inner cavity of the collecting bucket 17, preventing the flocs in the collecting bucket 17 from flowing into the interior of the reaction tank 1 again, and maintaining the content of flocs inside the reaction tank 1.

[0051] In order to prevent floccules from entering the external negative pressure chamber, the external negative pressure chamber is connected to the upper end of the adapter box 25, and the absorption tube 20 is connected to the bottom end of the adapter box 25, thereby preventing floccules from entering the negative pressure chamber as much as possible.

[0052] After the flocculants in the collecting bucket 17 are absorbed, the height of the collecting bucket 17 is adjusted again until the collecting bucket 17 is submerged below the liquid level in the reaction tank 1 again.

[0053] A drainage hole is provided at the bottom of the adapter box 25, and a filter screen 27 is provided at the drainage outlet. The filter screen 27 is used to filter the flocculants. A grille plate 28 for blocking the drainage hole is slidably installed on the bottom surface of the adapter box 25. After the collecting bucket 17 is immersed in the reaction tank 1 again, the grille plate 28 is slid until the grille plate 28 is offset from the drainage hole. At this time, the drainage hole is connected, and the water in the flocculants drips into the reaction tank 1 through the filter screen 27, thereby realizing water recovery.

[0054] When the collecting bucket 17 is raised, the grating plate 28 is slid until the grating plate 28 overlaps with the drainage hole to seal the drainage hole. At this time, a closed chamber is formed in the adapter box 25, so that negative pressure is formed in the adapter box 25 after the negative pressure chamber is connected.

[0055] In order to facilitate the control of the sliding of the grille plate 28, a transmission plate 29 is rotatably installed on the upper end surface of the connecting frame 18, and the other end of the transmission plate 29 is rotatably connected to the bottom surface of the grille plate 28. When the connecting frame 18 is raised, the transmission plate 29 pushes the grille plate 28 to close the drainage hole. When the connecting frame 18 is lowered, the transmission plate 29 drives the grille plate 28 to separate from the drainage hole so that the drainage hole is conductive.

[0056] After the collecting bucket 17 descends and sinks below the liquid surface, the drainage hole at the bottom of the transfer box 25 is connected, thereby maintaining the air pressure balance in the inner cavity of the transfer box 25.

[0057] The inner wall of the transfer box 25 is provided with a sealing piece 26 for one-way sealing of the absorption tube 20. The sealing piece 26 is made of elastic material, and a pin fixed to the inner wall of the transfer box 25 is fixedly installed on one side of the sealing piece 26. The sealing piece 26 controls the flocculants to pass through the absorption tube 20 only in one direction, preventing the flocculants inside the transfer box 25 from flowing back to the inside of the collecting bucket 17 through the absorption tube 20.

[0058] A closing plate 33 is slidably mounted on the side wall of the adapter box 25 . An elastic rubber ring is disposed outside the closing plate 33 . The elastic rubber ring is used to achieve a sealed connection between the adapter box 25 and the closing plate 33 .

[0059] Since the floc contains a large amount of metal substances, it can be used after recycling. In order to facilitate the removal of the floc in the transfer box 25, a scraper 32 is fixedly installed on the side wall of the closing plate 33 through a connecting rod. The outer wall of the scraper 32 is in contact with the inner wall of the transfer box 25. The outer wall of the transfer box 25 is elastically installed with a limit plate 34 for engaging with the closing plate 33. The limit plate 34 is moved until the limit plate 34 is separated from the closing plate 33. At this time, the closing plate 33 is pulled out toward the outer wall, and the scraper 32 is pulled to slide by the connecting rod. The scraper 32 slides out the floc inside the transfer box 25.
