Description

A regulating reservoir with a built-in purifier

[0001] This application claims priority to Chinese patent application No. 2024202538588, filed on February 2, 2024. This application incorporates the entirety of the aforementioned Chinese patent application. Technical Field

[0002] The present application relates to the technical field of regulating and storing tanks, and in particular to a regulating and storing tank with a built-in purifier. Background Art

[0003] On rainy days, the initial rainwater is mixed with a large amount of pollutants. It is necessary to build a storage tank to collect the initial rainwater, which is then slowly sent to the sewage treatment plant for treatment before being discharged into the water body. On rainy days, rainwater flows into the sewage pipe network, which greatly increases the amount of sewage and causes sewage to overflow from the pipe network or sewage treatment plant. It is necessary to build a sewage storage tank to store the excess sewage and then slowly send it to the sewage treatment plant for treatment. The main problems are: (1) For the initial rainwater storage tank, if it rains for several consecutive days, the initial rainwater stored in the storage tank will not have the opportunity to be transported to the sewage treatment plant for emptying and standby use, and the ability to store the initial rainwater will be lost; (2) For the sewage storage tank, if it rains for several consecutive days, the sewage stored in the storage tank will not have the opportunity to be transported to the sewage treatment plant for emptying and standby use, and the ability to store the sewage will be lost.

[0004] To address these technical issues, existing technologies have gradually introduced purifying reservoirs. These reservoirs are equipped with water purification modules, typically containing microbial fillers. However, during heavy rainfall, rainwater significantly scours the reservoir's shell, particularly the microbial fillers, causing the loss of microorganisms.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] The purpose of this application is to provide a regulating storage tank with a built-in purifier to solve the problems existing in the prior art, so that the regulating storage tank itself has the ability to treat sewage, and can reduce the impact of microorganisms in the rainwater regulating storage tank shell and the water purification module, avoid the loss of microorganisms in the water purification module, and ensure the water purification capacity of the water purification module.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] As shown in Figures 1 to 7, this embodiment provides a regulating reservoir with a built-in purifier, including a regulating reservoir shell 301 that encloses the regulating reservoir, and a water inlet pool 11, a first energy dissipation step 908 and a water purification module are provided in the regulating reservoir, and a water inlet 6 and a drain are provided at both ends of the top of the water inlet pool 11, respectively. Along the direction of water flow, an energy dissipation wall 10 and a grille 9 are provided in sequence between the water inlet 6 and the drain; the drain is connected to the regulating reservoir, and the first energy dissipation step 908 is located below the drain; a hydraulic flushing device 99 is provided at the bottom of the regulating reservoir, and a mud discharge trough 888 is provided at one end of the bottom plate of the regulating reservoir, a water outlet pump 77 is provided in the upper part of the mud discharge trough 888, and a mud discharge pump 88 is provided at the bottom of the mud discharge trough 888.

[0031] During use, the initial rainwater (or sewage) enters the water inlet pool 11 through the water inlet 6, then passes through the energy dissipation wall 10 for energy dissipation, and then passes through the grille 9 to filter the large-volume impurities in the rainwater, and then flows out from the drain outlet, and enters the regulating reservoir after the second energy dissipation of the first energy dissipation step 908. When the liquid level in the regulating reservoir reaches the maximum water level, the water intake is stopped. The water purification module purifies the rainwater. When the water quality meets the standard, the water outlet pump 77 is used to discharge the water from the regulating reservoir. The sludge mixed in the rainwater and the sediment generated during the water purification process sink to the bottom of the regulating reservoir. The hydraulic flushing equipment 99 can be used to discharge the sludge sediment into the sludge trough 888, and finally the sludge sediment is discharged through the sludge pipe 8 by the sludge pump 88 and sent to the nearby sewage network.

[0032] Therefore, this embodiment can reduce the flow rate of rainwater entering the water storage tank by setting up an inlet pool 11 with an energy dissipation wall 10 and a first energy dissipation step 908 located below the inlet pool 11, thereby reducing the impact of microorganisms in the rainwater storage tank shell 301 and the water purification module, avoiding the loss of microorganisms in the water purification module, and ensuring the water purification capacity of the water purification module.

[0033] The storage tank in this embodiment is also equivalent to a sedimentation tank. After the initial rainwater is treated by biological means and coagulation and sedimentation, the clean water can be discharged directly by the outlet pump 77 or discharged from top to bottom using a decanter.

[0034] Furthermore, in this embodiment, a second energy dissipation step 9081 is provided at the end of the sludge trough 888. The top of the second energy dissipation step 9081 is connected to the bottom plate of the storage tank. The second energy dissipation step 9081 can reduce the flow rate of water entering the sludge trough 888, thereby facilitating the sedimentation of sludge in the trough 888.

[0035] This embodiment also includes a control room 902, a power distribution room 903, a fan room 904, a deodorization room 905, and a dosing room 907, all located above the regulating reservoir. Automatic control equipment and online water quality testing equipment are installed in the control room 902; power distribution equipment is installed in the power distribution room 903; aeration fans and cleaning fans are installed in the fan room 904; deodorization equipment is installed in the deodorization room 905; and dosing equipment, such as phosphorus removal agent dosing equipment, carbon source dosing equipment, and disinfectant dosing equipment, is installed in the dosing room 907. The equipment installed in the control room 902, power distribution room 903, fan room 904, deodorization room 905, and dosing room 907 are all existing equipment, and their structures and methods of use are well known to those skilled in the art. The control room 902, power distribution room 903, fan room 904, deodorization room 905, and dosing room 907 are connected. An equipment entrance and exit 906 for entering and exiting the deodorization room 905 is also provided above the regulating reservoir.

[0036] Furthermore, in this embodiment, a regenerated water chamber 909 is located above, beside, or within the regulating reservoir. The outlet pump 77 is connected to an outlet pipe 7, which has a first branch and a second branch. The first branch connects to the regenerated water chamber 909, while the second branch connects to the river water supply network. Valves are installed on both the first and second branches. A regenerated water tank and a regenerated water pump are installed within the regenerated water chamber 909. The regenerated water tank is connected to the first branch. The regenerated water pump is located inside or outside the regenerated water tank and is used to pump water from the regenerated water tank to a surface regenerated water filling station.

[0037] After a period of treatment, the wastewater in the storage tank meets discharge standards, based on time or water quality testing. The water is then pumped out via the first branch pipe into the regeneration tank in the regeneration room 909. When the tank reaches the maximum level, the remaining water is discharged via the second branch pipe into the nearby river for ecological replenishment. Disinfectant is added to the regeneration tank to kill bacteria, and the regeneration pump then pumps the water back into the water truck for reuse in landscaping, sanitation, and other areas.

[0038] Furthermore, in this embodiment, the hydraulic flushing equipment 99 includes a submersible pump and a rotating water spray pipe connected to the submersible pump.

[0039] Furthermore, in this embodiment, a storage tank maintenance channel 901 and a submersible pump maintenance channel 9011 are provided in the storage tank.

[0040] Furthermore, in this embodiment, the water purification module can be arranged in the regulating and storage tank in the form of a bioreactor module 303, or the microbial filler 304 can be directly arranged in the regulating and storage tank.

[0041] The bioreactor module 303 includes a housing with a support at the bottom. The housing has a top opening and a bottom opening, respectively. A microbial filler 304 is located within the housing. An aeration device 5 is located below the microbial filler 304 and is connected to an aeration fan. The microbial filler 304 includes either fixed filler 13 or floating filler. The upper and lower ends of the fixed filler 13 are secured to the upper support 14 and lower support within the housing via upper connectors 16 and lower connectors 17, respectively. The floating filler is either a heavy filler 212 or a lightweight filler 213. A filter plate 18 is located within the housing. The heavy filler 212 is located above the filter plate 18, while the lightweight filler 213 is located below the filter plate 18.

[0042] As shown in Figures 4 to 7, this embodiment provides a purification reservoir system 300, comprising the reservoir 300, a bioreactor module 303, and a lifting mechanism. The reservoir 300 is constructed of concrete. A control cabinet 99 is located outside the reservoir 300. The reservoir 300 is connected to an inlet pipe 6 and an outlet pipe 7. A liquid level gauge 88 is located within the reservoir 300 for detecting the liquid level. The inlet pipe 6 is provided with an inlet valve 66. A water quality detector 777 is located within the reservoir 300 for detecting water quality. The outlet pipe 7 is provided with an outlet valve. The liquid level gauge 88, inlet valve 66, outlet valve, and water quality detector 777 are all electrically connected to the control cabinet 99. The bioreactor module 303 includes a housing 302, constructed of stainless steel, located within the reservoir 300. A stainless steel support frame 81 is located at the bottom of the housing 302, with a water inlet 8 disposed on the support frame. The top and bottom of the box body 302 are respectively provided with a top opening and a bottom opening, and microbial fillers are provided inside the box body 302 from top to bottom, and a lifting mechanism is used to lift the sewage to act on the microbial fillers; the microbial fillers include fixed fillers 13 or floating fillers; the upper and lower ends of the fixed filler 13 are fixed to the upper support body 14 and the lower support body 15 in the box body 302 through the upper connecting piece 16 and the lower connecting piece 17 respectively; the floating filler is a heavy filler 212 or a light filler 213, and a filter plate 18 is provided in the box body 302. The heavy filler 212 is loaded in the box body 302 and is located above the filter plate 18. The gravity it is subjected to is greater than the force of water. Under the action of gravity, it can be accumulated above the filter plate 18, and will not fall away from the box body 302 even under the impact of water flow; the light filler 213 is loaded in the box body 302 and is accumulated below the filter plate 18 under the action of buoyancy. A filter head 50 is provided on the filter plate 18. The fixed filler 13 includes short fiber strings, elastic filler strings, fiber fabrics or long fiber bundles; the heavy filler 212 includes ceramsite, and the light filler 213 includes foam plastic beads or plastic rings.

[0043] This embodiment, by placing a bioreactor module 303 within the storage tank 300, can directly purify sewage using microbial fillers. This eliminates the need for a sewage treatment plant near the storage tank 300 and the need for post-transport purification of rainwater in the storage tank 300. Furthermore, the bioreactor module 303 does not occupy ground or underground space and takes up virtually no volume of the storage tank 300, significantly saving investment and operating costs. Furthermore, the upper support 14, lower support 15, or filter plate 401 provided within the housing 302 can confine the fixed filler 13 or floating filler within the housing 302, preventing loss of the biofiller.

[0044] As an implementation method of this embodiment, the microbial filler includes an aerobic microbial filler 401 and an anoxic microbial filler 402 located below the aerobic microbial filler 401, and the aerobic microbial filler 401 and the anoxic microbial filler 402 are both located below the sewage liquid surface; the lifting mechanism includes an aeration device, the aeration device includes an aeration fan and an aeration pipe 5 connected to the aeration fan, the aeration pipe 5 is located between the aerobic microbial filler 401 and the anoxic microbial filler 402, and a plurality of upward-facing aeration holes are opened on the aeration pipe 5.

[0045] Working principle:

[0046] At the beginning of a rainstorm, control cabinet 99 opens water inlet valve 66. Initial rainwater (sewage) flows through water inlet pipe 6 and grille 666 into regulating reservoir 300. When the liquid level reaches the maximum level, liquid level gauge 88 sends a signal to control cabinet 99, which in turn sends a closing command to water inlet valve 66, closing it. The aeration fan is activated, and aerated air enters aeration pipe 5 and passes from bottom to top through aerobic microbial filler 401 at the top. Within aerobic microbial filler 401, organic matter and ammonia nitrogen pollutants in the water are catalytically decomposed and removed by aerobic microorganisms within aerobic microbial filler 401. Due to the air stripping effect, water enters anoxic microbial filler 402 from the bottom of bioreactor module 303, passing through anoxic microbial filler 402 from bottom to top, and then again through aerobic microbial filler 401 from bottom to top. Within anoxic microbial filler 402, total nitrogen and organic matter in the water are catalytically decomposed and removed by the denitrifying anoxic microorganisms within anoxic microbial filler 402. After a period of treatment, the water in the storage tank 300 meets discharge standards based on time or water quality testing. Drain pump 77 is activated to discharge the water through outlet pipe 7, ready to receive the initial rainwater of the next rainfall. During the next rain, a small amount of water is sprayed on the microbial packing to keep it moist. Alternatively, sewage from a nearby sewage pipe network is diverted to the storage tank 300 for further treatment.

[0047] In this embodiment, the upper support body 14 and the lower support body 15 are grating plates made of glass fiber reinforced plastic. The upper support body 14 and the lower support body 15 are circular in planar shape and are installed in the box body 302 to form a cylindrical water purification module.

[0048] When the microbial filler 304 is directly installed in the regulating and storage tank, an aeration device 5 is installed below the microbial filler 304. The microbial filler 304 includes a fixed filler 13 or a floating filler. The upper and lower ends of the fixed filler 13 are respectively fixed to the upper support body 14 and the lower support body in the regulating and storage tank housing 301. The floating filler is a heavy filler 212 or a light filler 213. A filter plate 18 is installed in the regulating and storage tank housing 301. The heavy filler 212 is installed in the regulating and storage tank housing 301 and is located above the filter plate 18. The light filler 213 is installed in the regulating and storage tank housing 301 and is located below the filter plate 18. A filter head 50 is installed on the filter plate 18.

[0049] The fixed filler 13 includes short fiber strings, elastic filler strings, fiber fabrics, non-woven fabrics or long fiber bundles; the heavy filler 212 includes ceramsite, volcanic rock, quartz sand, and the light filler 213 includes foam plastic beads or plastic rings.

[0050] After the sewage enters the regulating and storage tank, the aeration fan is started, and the aeration air enters the aeration device 5 and passes through the microbial filler 304 from bottom to top. Due to the air lift effect, the sewage passes through the microbial filler 304 from bottom to top. Under the action of aerobic microorganisms, the organic matter and ammonia nitrogen pollutants in the water are catalytically decomposed and removed by aerobic microorganisms. Under the action of anoxic microorganisms in the anoxic area of ​​the microbial filler 304 (away from the aeration device 5 area), the total nitrogen and organic matter in the water are catalytically decomposed and removed by anoxic microorganisms such as denitrifying bacteria. After the sewage in the regulating and storage tank is treated for a period of time and meets the discharge standards according to time or water quality inspection, the outlet pump 77 is started and discharged first into the regenerated water tank in the regenerated water room 909 through the outlet pipe 7. When the regenerated water tank reaches the high water level, the remaining water is discharged into the nearby river for ecological water replenishment. After the regulating and storage tank is emptied, it waits to receive the initial rainwater of the next rain or inject sewage into the pipe network. While waiting for the next rain, a small amount of water should be sprayed on the microbial filler 304 to keep the filler moist; or the sewage in the nearby sewage pipe network should be introduced into the regulating tank to continue treating the sewage.

[0051] To ensure that total phosphorus and total nitrogen meet the standards, phosphorus removal agents such as polyaluminum chloride can be added to the regulating reservoir through phosphorus removal dosing equipment, and carbon sources such as sodium acetate can be added to the regulating reservoir through carbon source dosing equipment.

[0052] Demolding and cleaning process of microbial filler 304:

[0053] Turn off the aeration fan and start the cleaning fan, which is connected to the cleaning air distribution device 4. The cleaning air distribution device 4 is located at the bottom of the microbial filler 304 and can remove the film and clean the microbial filler 304 in different areas. The aged microbial film on the biofiller is stripped and enters the water of the regulating and storage tank, where it settles to the bottom of the regulating and storage tank after 1-2 hours.

[0054] It should be noted that the air jet holes on the cleaning air distribution device 4 have a large aperture, and the air intake of the cleaning blower is also large. However, the aperture on the aeration pipe is small, and the aeration air volume is also small, which cannot play an effective cleaning role.

[0055] Adaptive changes based on actual needs are all within the scope of protection of this application.

[0056] It should be noted that it is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present application is defined by the appended claims, not the foregoing description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present application. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
