Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, and in particular to modular assembled sewage treatment equipment and a construction process thereof. Background Art

[0002] Modular prefabricated sewage treatment equipment is a modular design of various treatment units such as screens, regulating tanks, biochemical tanks, sedimentation tanks, etc. After prefabrication in the factory, it is transported to the site for assembly and debugging. Modular prefabricated sewage treatment equipment has multiple advantages such as short construction period, high construction quality, cost savings, strong flexibility and intelligent management, and has become a new trend in future sewage treatment.

[0003] Patent No. CN118122024B discloses a sewage treatment device, including a floating object treatment section and a suspended matter and sediment treatment section, the floating object treatment section is located at a higher position than the suspended matter and sediment treatment section, a turbulent floating object filtering mechanism is installed in the floating object treatment section, and a vibrating suspended matter and sediment filtering mechanism is installed inside the suspended matter and sediment treatment section. The present invention sets a turbulent floating object filtering mechanism, which not only pre-filters the floating objects in the sewage during the rotation process, but also turbulents the sewage, thereby constantly changing the water flow rate per unit time to trigger the frequent vibration of the vibrating suspended matter and sediment filtering mechanism, so that when filtering suspended matter and sediment, the suspended matter and sediment are not easy to accumulate on the filter screen, the sewage will be smoother during treatment, and no manual intervention is required at all times, and the overall sewage treatment efficiency is higher.

[0004] In the prior art, the filter mechanism is frequently vibrated to prevent suspended matter and sediment from accumulating on the filter screen, making sewage treatment smoother. However, sewage contains not only floating or precipitated garbage, but also some grease and floating particulate matter. These substances will first adhere to the inner side of the sewage treatment equipment, causing corrosion of the inner wall of the sewage treatment equipment and shortening the service life of the sewage treatment equipment. Second, if these substances are not treated and discharged into the water or the surface, they will cause environmental pollution and affect the ecological environment. Summary of the invention

[0005] The purpose of the present invention is to provide a modular assembled sewage treatment equipment and its construction process to solve the following technical problems:

[0006] There are some grease and floating particulate matter in domestic sewage.

[0026] A modular assembled sewage treatment construction process, the construction process comprising the following steps:

[0027] S1: The factory will prefabricate the sewage pipes, sewage diversion boxes and sewage treatment equipment, and then transport them to the construction site by transport vehicles.

[0028] S2: When the sewage pipe, sewage diversion box and sewage treatment device arrive at the construction site, use an excavator to excavate at the layout location. After the excavation is completed, the bottom of the foundation pit is leveled. After the leveling is completed, a concrete cushion layer is poured on the bottom of the foundation pit. After the concrete cushion layer solidifies, the sewage pipe, sewage diversion box and sewage treatment device are lifted by a crane, and the sewage pipe, sewage diversion box and sewage treatment device are placed on the concrete cushion layer of the foundation pit, and spliced ​​and installed according to the drawings;

[0029] S3: After the installation of sewage pipes, sewage diversion boxes and sewage treatment plants is completed, the staff will first debug the sewage pipes, sewage diversion boxes and sewage treatment plants. When the sewage pipes, sewage diversion boxes and sewage treatment plants are tested and can operate normally, the foundation pit will be backfilled and the soft soil on both sides of the sewage pipes, sewage diversion boxes and sewage treatment plants will be compacted to make them dense, so that the sewage pipes, sewage diversion boxes and sewage treatment plants can be firmly buried underground.

[0030] Beneficial effects of the present invention:

[0031] (1) The rotating dosing component will be used to inject the agent into the sewage treatment device at intervals, so that the agent and domestic sewage can be integrated. The rotating dosing component will also disturb the domestic sewage, so that the domestic sewage and the agent can be quickly integrated, and the grease and floating particles in the domestic sewage can be solidified into flocs, so that they can all sink to the bottom of the sewage treatment device, thereby preventing the sewage treatment device from being used for a long time, and allowing grease and floating particles to adhere to the inner wall of the sewage treatment device, causing corrosion inside the sewage treatment device, and preventing untreated domestic sewage from being discharged into the water body or the surface, which will cause environmental pollution and affect the ecological environment;

[0032] (2) The switch assembly is driven by the driving assembly to move up and down so that the domestic sewage flows into the deep part of the sewage treatment device. The switch assembly is set to control the flow rate of the domestic sewage. The switch assembly can speed up or reduce the flow rate of the domestic sewage according to the needs. When a certain demand is reached, the switch assembly is closed, so that the domestic sewage no longer flows into the deep part of the sewage treatment device, thereby achieving a domestic sewage control effect;

[0033] (3) After the grease and floating particles are sunk to the bottom due to the action of the agent, the domestic sewage will be stratified, with the upper layer being the domestic sewage clear liquid and the lower layer being the flocculent sediment of the grease and floating particles. The upper layer of the domestic sewage clear liquid is first pumped out of the sewage treatment device through the sewage discharge component, and the sewage discharge component suction port floats on the liquid surface of the domestic sewage clear liquid. In this way, the suction port in the sewage discharge component will descend according to the liquid surface of the domestic sewage clear liquid. When the suction reaches a certain position, the suction port in the sewage discharge component stops descending. This setting is to ensure that the suction port in the sewage discharge component only extracts the domestic sewage clear liquid and does not extract the grease and flocculent sediment of the floating particles in the lower layer;

[0034] (4) When the upper domestic sewage clear liquid is extracted, the lower sewage outlet of the sewage discharge component will be activated to extract and discharge the flocculent sediment of grease and floating particles in the lower layer. It is possible that a small amount of flocculent sediment of grease and floating particles will remain in the sewage treatment plant. When the switch component is started again, a new batch of untreated domestic sewage will quickly rush into the sewage treatment plant. At this time, the small amount of remaining grease and flocculent sediment of floating particles in the previous batch will be washed away by the fast-flowing domestic sewage, so that they will be pushed to one end of the sewage treatment plant for accumulation, and will be discharged from the sewage treatment plant together when they are extracted again.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-Figure 6 As shown, the present invention is a modular assembled sewage treatment equipment, comprising a sewage pipe 1, a sewage diversion box 2 and a sewage treatment device 3; and also comprising a sewage cleaning and discharge unit arranged in the sewage treatment device 3;

[0045] The sewage diversion box 2 is fixedly arranged at one end of the sewage pipe 1;

[0046] The sewage treatment device 3 is fixedly arranged at one end of the sewage diversion box 2 away from the sewage pipe 1, and the sewage treatment device 3 is installed in multiple sets;

[0047] The sewage cleaning and drainage unit is arranged in the sewage treatment module 3, and includes a driving component, a switch component, a dosing component and a sewage discharge component; the switch component includes a mechanical compartment 23, a first tooth plate 24 and a gate 30; the driving component drives the switch component to switch; the switch component guides the sewage to drive the dosing component to rotate; the sewage discharge component expands and contracts with the sewage liquid level; the dosing component includes a special-shaped opening 15; the end of the special-shaped opening 15 close to the mechanical compartment 23 is a wide opening, and the end away from the mechanical compartment 23 is a narrow opening;

[0048] Domestic sewage is discharged from the sewage pipe 1 into the sewage diversion box 2, and the sewage is controlled to flow into the sewage treatment device 3 through the sewage diversion box 2. Then, the driving component in the sewage treatment device 3 drives the switch component to rise and fall, so that the sewage flows quickly. The fast-flowing sewage impacts the dosing component, so that the dosing component puts in the medicine to mix the medicine with the sewage. The medicine solidifies and precipitates the grease and floating particles in the sewage. After the sewage is precipitated, the clear liquid above and the sediment below are discharged by the sewage discharge component;

[0049] Domestic sewage is collected through the sewage pipe 1, and the collected domestic sewage flows into the sewage diversion box 2. The sewage diversion box 2 sends the sewage into the sewage treatment device 3 respectively. The sewage diversion box 2 is set to discharge domestic sewage according to the treatment capacity of each sewage treatment device 3, so as to avoid excessive discharge of domestic sewage into the sewage treatment device 3, which exceeds the treatment capacity of the sewage treatment device 3. After the domestic sewage enters the sewage treatment device 3, the switch component is driven by the driving component to move up and down to allow the domestic sewage to flow into the depth of the sewage treatment device 3. The switch component is set to control the flow speed of the domestic sewage. The switch component can speed up or reduce the flow speed of the domestic sewage according to the needs. When a certain demand is reached, the switch component is closed, so that the domestic sewage no longer flows to the depth of the sewage treatment device 3, which plays a role in controlling domestic sewage.

[0050] When the switch assembly is turned on to allow domestic sewage to enter the deep part of the sewage treatment device 3, the rapidly flowing sewage causes the dosing assembly in the sewage treatment device 3 to rotate, and the rotating dosing assembly will inject the medicine into the sewage treatment device 3 at intervals, so that the medicine and the domestic sewage are integrated, and the rotating dosing assembly will also disturb the domestic sewage, so that the domestic sewage and the medicine are quickly integrated, and the grease and floating particles in the domestic sewage are coagulated into floccules, so that they all sink to the bottom of the sewage treatment device 3, thus avoiding the sewage treatment device 3 from being used for a long time, causing the grease and floating particles in the domestic sewage to adhere to the inner wall of the sewage treatment device 3, causing corrosion inside the sewage treatment device 3, reducing the service life of the sewage treatment device 3, and also avoiding the untreated domestic sewage from being discharged into the water body or the surface, which will cause environmental pollution and affect the ecological environment;

[0051] When the grease and floating particles are sunk to the bottom due to the action of the agent, the domestic sewage will be stratified, with the upper layer being the domestic sewage clear liquid and the lower layer being the flocculent sediment of the grease and floating particles. The upper domestic sewage clear liquid is first pumped out of the sewage treatment device 3 through the sewage discharge component. The sewage discharge component suction port floats on the liquid surface of the domestic sewage clear liquid, so that the suction port in the sewage discharge component will drop according to the liquid surface of the domestic sewage clear liquid. When the suction reaches a certain position, the suction port in the sewage discharge component stops dropping. This setting is to ensure that the suction port in the sewage discharge component only extracts the domestic sewage clear liquid, and does not extract the grease and flocculent sediment of the floating particles in the lower layer;

[0052] When the upper domestic sewage clear liquid is extracted, the lower sewage suction port of the sewage discharge component will be started to extract and discharge the flocculent sediment of grease and floating particles in the lower layer. It is possible that a small amount of flocculent sediment of grease and floating particles will remain in the sewage treatment device 3. When the switch component is started again, a new batch of untreated domestic sewage will quickly rush into the sewage treatment device 3. At this time, the small amount of remaining flocculent sediment of grease and floating particles in the previous batch will be washed away by the fast-flowing domestic sewage, so that it will be pushed to one end of the sewage treatment device 3 for accumulation, and will be discharged from the sewage treatment device 3 together when it is extracted again.

[0053] See also Figure 2 , Figure 3 and Figure 4 As shown, the driving assembly includes a driving motor 10, a driving shaft 25 and a driving gear 26;

[0054] The driving motor 10 is fixedly arranged outside the sewage treatment device 3; the driving shaft 25 is rotatably arranged in the mechanical compartment 23; the driving gear 26 is fixedly arranged in the middle of the driving shaft 25;

[0055] The mechanical compartment 23 is disposed inside the sewage treatment device 3; the gate 30 is slidably disposed at the bottom of the mechanical compartment 23; a first tooth plate 24 is fixedly connected to the top of the gate 30; the first tooth plate 24 is meshed with the driving gear 26;

[0056] The driving motor 10 drives the driving shaft 25 to rotate, and the rotating driving shaft 25 causes the driving gear 26 to rotate together. The rotating driving gear 26 will drive the first tooth plate 24 in the mechanical compartment 23, so that the first tooth plate 24 rises or falls along the rotation direction of the driving gear 26. The rising and falling first tooth plate 24 pulls the gate 30 to open and close, thereby controlling the domestic sewage to enter the interior of the sewage treatment device 3. The driving motor 10 can control the driving shaft 25 to rotate quickly or slowly, so that the gate 30 can be immediately raised, lowered, or slowly raised and lowered, thereby controlling the flow rate of domestic sewage.

[0057] See also Figure 2 and Figure 6 As shown, the medication delivery assembly includes a driven shaft 17, a fan blade 16 and a rotating plate 19;

[0058] The drug administration assembly also includes a drug administration box 5, a drug administration box pipeline 31, a drug administration plate 18 and a drug administration box door 6;

[0059] The medicine box pipe 31 is fixedly arranged at the top center of the sewage treatment device 3; the medicine feeding box 5 is fixedly arranged at the top of the medicine box pipe 31; the medicine feeding plate 18 is fixedly arranged at the middle of the inner side of the medicine box pipe 31; the medicine box door 6 is slidably arranged at the top of the medicine feeding box 5;

[0060] The special-shaped opening 15 is fixedly arranged below the mechanical compartment 23; the driven shaft 17 is rotatably arranged inside the sewage treatment device 3 and is located at one end of the special-shaped opening 15; the driven shaft 17 is fixedly connected with a fan blade 16, and the fan blade 16 is kept horizontal with the special-shaped opening 15; the driven shaft 17 passes through the dosing plate 18; the rotating plate 19 is fixedly arranged on the driven shaft 17 and is located above the dosing plate 18;

[0061] The gate 30 is used to control the domestic sewage to enter the deep part of the sewage treatment device 3 quickly or slowly. The domestic sewage will enter the special-shaped opening 15 through the gate 30. The end of the special-shaped opening 15 close to the mechanical bin 23 is a wide opening, and the end away from the mechanical bin 23 is a narrow opening. This will cause a strong impact force on the domestic sewage, which will impact the fan blades 16 to rotate. The rotating fan blades 16 drive the driven rods to rotate, and the rotating driven rods will cause the rotating plate 19 to rotate. There are holes on the rotating plate 19, and holes are also provided on the dosing plate 18. When the holes on the rotating plate 19 coincide with the holes on the dosing plate 18, the medicine in the dosing box 5 is put into the sewage treatment device 3 through the medicine box pipe 31. The rotating fan blades 16 will also disturb the domestic sewage, mix the domestic sewage with the medicine, and turn the grease and floating particles in the domestic sewage into flocs to sink to the bottom.

[0062] See also Figure 2 and Figure 6 As shown, the sewage discharge assembly includes a liquid outlet pipe 4, a telescopic hose 20, a floating block 21 and a limiting rod 32;

[0063] The limiting rod 32 is fixedly arranged inside the sewage treatment device 3; two limiting rods 32 are provided and symmetrically arranged inside the sewage treatment device 3; the floating block 21 is fixedly arranged at the bottom of the limiting rod 32; the telescopic hose 20 is fixedly arranged in the middle of the floating block 21, and the other end of the telescopic hose 20 is fixedly arranged inside the sewage treatment device 3; the liquid outlet pipe 4 is fixedly arranged at the top of the sewage treatment device 3, and the liquid outlet pipe 4 is connected to the telescopic hose 20;

[0064] After the domestic sewage is precipitated and stratified, the external pump is used to pump the telescopic hose 20 to extract the upper layer of domestic sewage clear liquid in the sewage treatment device 3, and then discharge it from the sewage treatment device 3 through the liquid outlet pipe 4. The extraction will cause the liquid level of the domestic sewage clear liquid to drop, and the dropping of the liquid level of the domestic sewage clear liquid will cause the floating block 21 to drop along with the liquid level, so that the telescopic hose 20 keeps pumping the domestic sewage clear liquid, preventing the telescopic hose 20 from pumping up the grease and floating particle flocs precipitated at the bottom. By setting the telescopic stroke of the limiting rod 32, the floating block 21 and the telescopic hose 20 can only stop descending after descending to a certain distance, preventing the grease and floating particle flocs precipitated at the bottom from being pumped up.

[0065] See also Figure 2 and Figure 4 As shown, the sewage discharge assembly also includes a stacking box 12 and a sewage extraction pipe 11;

[0066] The stacking box 12 is fixedly arranged at the bottom of the sewage treatment device 3; the sewage extraction pipe 11 is fixedly arranged at one end of the stacking box 12;

[0067] The bottom of the sewage treatment device 3 is set at an inclined angle, and the precipitated grease and floating particle flocs will slide into the stacking box 12. After the domestic sewage clear liquid is extracted, the pump will allow the sewage suction pipe 11 to pump the grease and floating particle flocs accumulated in the stacking box 12, so that the grease and floating particle flocs can be discharged from the sewage treatment device 3. A small amount of grease and floating particle flocs will remain in the sewage treatment device 3. When the gate 30 releases new untreated domestic sewage, the grease and floating particle flocs in the sewage treatment device 3 will be flushed, allowing them to fall into the stacking box 12, and when they are extracted again through the sewage suction pipe 11, they will be discharged from the sewage treatment device 3 together.

[0068] See also Figure 2 and Figure 3As shown, a sliding groove 27 is provided on the mechanical compartment 23; a moving plate 29 is slidably connected in the sliding groove 27; a second tooth plate 28 is fixedly connected to one end of the moving plate 29; the second tooth plate 28 is meshed with the driving gear 26; a scraping plate 22 is fixedly connected to one end of the moving plate 29 away from the second tooth plate 28; the scraping plate 22 slides in the sewage treatment device 3;

[0069] There will be some grease and floating particles sticking to the inner wall of the sewage treatment device 3. The second tooth plate 28 is driven to rise and fall by rotating the driving gear 26, so that the movable plate 29 slides in the sliding groove 27. The sliding movable plate 29 drives the scraper plate 22 to rise and fall, so that the scraper plate 22 scrapes the inside of the sewage treatment device 3 to scrape off the residual grease and floating particles, so as to prevent the grease and floating particles from corroding the inner wall of the sewage treatment device 3.

[0070] See also Figure 2 and Figure 5 As shown, the sewage treatment device 3 is located at one end of the mechanical compartment 23 and is fixedly connected to a filter plate 13; the sewage treatment device 3 is fixedly connected to a trash bin 8; a box cover 9 is slidably connected to the top of the trash bin 8; filter holes 14 are opened in the trash bin 8 and are evenly arranged in the trash bin 8 and connected to the sewage treatment device 3; the other end of the sewage extraction pipe 11 is fixedly set on one side of the trash bin 8;

[0071] When the sewage diversion box 2 discharges domestic sewage into the sewage treatment device 3, there will be large pieces of domestic garbage in the domestic sewage, so these large pieces of domestic garbage will be preliminarily intercepted and filtered through the filter plate 13 in the sewage treatment device 3. The intercepted and filtered large pieces of domestic garbage will slide into the garbage bin 8. When they are accumulated to a certain extent, the top box cover 9 of the garbage bin 8 will be opened to allow the sewage pumping truck to remove the garbage in the garbage bin 8 to avoid the accumulation of domestic sewage in the garbage bin 8. Therefore, a filter hole 14 is opened on the side wall of the garbage bin 8, and the domestic sewage is re-discharged into the sewage treatment device 3 through the filter hole 14 to avoid the garbage overflowing from the garbage bin 8 and causing pollution due to the influx of domestic sewage.

[0072] See also Figures 1 to 6 As shown, a modular assembled sewage treatment construction process includes the following steps:

[0073] S1: The factory prefabricates the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3, and after the processing, these devices are transported to the construction site by a transport vehicle;

[0074] S2: When the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 arrive at the construction site, an excavator is used to excavate at the layout location. After the excavation is completed, the bottom of the foundation pit is leveled. After the leveling is completed, a concrete cushion layer is poured on the bottom of the foundation pit. After the concrete cushion layer solidifies, the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 are lifted by a crane, and the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 are placed on the concrete cushion layer of the foundation pit, and spliced ​​and installed according to the drawings;

[0075] S3: After the installation of sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 is completed, the staff will first debug the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3. When the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 are tested and can operate normally, the foundation pit will be backfilled and the soft soil on both sides of the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 will be compacted to make it dense, so that the sewage pipe 1, sewage diversion box 2 and sewage treatment device 3 can be firmly buried underground.

[0076] The working principle of the present invention is as follows: domestic sewage is collected through a sewage pipe 1, and the collected domestic sewage flows into a sewage diversion box 2, and the sewage diversion box 2 sends the sewage into a sewage treatment device 3 respectively. The sewage diversion box 2 is provided to discharge domestic sewage into it according to the treatment capacity of each sewage treatment device 3, so as to avoid excessive discharge of domestic sewage into the sewage treatment device 3, which exceeds the treatment capacity of the sewage treatment device 3. After the domestic sewage enters the sewage treatment device 3, the switch component is driven by the driving component to move up and down so that the domestic sewage flows into the deep of the sewage treatment device 3. The switch component is provided to control the flow speed of the domestic sewage. The switch component can speed up or reduce the flow speed of the domestic sewage according to the needs. When a certain demand is reached, the switch component is closed, so that the domestic sewage does not flow to the deep of the sewage treatment device 3, thereby achieving a domestic sewage control effect.

[0077] When the switch assembly is turned on to allow domestic sewage to enter the deep part of the sewage treatment device 3, the rapidly flowing sewage causes the dosing assembly in the sewage treatment device 3 to rotate, and the rotating dosing assembly will inject the medicine into the sewage treatment device 3 at intervals, so that the medicine and the domestic sewage are integrated, and the rotating dosing assembly will also disturb the domestic sewage, so that the domestic sewage and the medicine are quickly integrated, and the grease and floating particles in the domestic sewage are coagulated into floccules, so that they all sink to the bottom of the sewage treatment device 3, thus avoiding the sewage treatment device 3 from being used for a long time, causing the grease and floating particles in the domestic sewage to adhere to the inner wall of the sewage treatment device 3, causing corrosion inside the sewage treatment device 3, reducing the service life of the sewage treatment device 3, and also avoiding the untreated domestic sewage from being discharged into the water body or the surface, which will cause environmental pollution and affect the ecological environment;

[0078] When the grease and floating particles are sunk to the bottom due to the action of the agent, the domestic sewage will be stratified, with the upper layer being the domestic sewage clear liquid and the lower layer being the flocculent sediment of the grease and floating particles. The upper domestic sewage clear liquid is first pumped out of the sewage treatment device 3 through the sewage discharge component. The sewage discharge component suction port floats on the liquid surface of the domestic sewage clear liquid, so that the suction port in the sewage discharge component will drop according to the liquid surface of the domestic sewage clear liquid. When the suction reaches a certain position, the suction port in the sewage discharge component stops dropping. This setting is to ensure that the suction port in the sewage discharge component only extracts the domestic sewage clear liquid, and does not extract the grease and flocculent sediment of the floating particles in the lower layer;

[0079] When the upper domestic sewage clear liquid is extracted, the lower sewage suction port of the sewage discharge component will be started to extract and discharge the flocculent sediment of grease and floating particles in the lower layer. It is possible that a small amount of flocculent sediment of grease and floating particles will remain in the sewage treatment device 3. When the switch component is started again, a new batch of untreated domestic sewage will quickly rush into the sewage treatment device 3. At this time, the small amount of remaining flocculent sediment of grease and floating particles in the previous batch will be washed away by the fast-flowing domestic sewage, so that it will be pushed to one end of the sewage treatment device 3 for accumulation, and will be discharged from the sewage treatment device 3 together when it is extracted again.

[0080] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
