Description
Technical Field
[0001] The utility model relates to the technical field of regulating and storing pools, in particular to a regulating and storing pool with a built-in purifier. Background Art
[0002] 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, which is then slowly sent 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, 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, and the ability to store the sewage will be lost.
[0003] In order to solve the above technical problems, a regulating reservoir with purification function has gradually appeared in the prior art.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The purpose of the utility model 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.
[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] 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 drainage port, and enters the regulating and storing tank after the secondary energy dissipation of the first energy dissipation ladder 908. When the liquid level in the regulating and storing tank reaches the maximum water level, the water intake is stopped. The water purification module purifies the rainwater. When the water quality meets the standard, it is discharged from the regulating and storing tank by the outlet pump 77. The sludge mixed in the rainwater and the sediment generated during the water purification process sink to the bottom of the regulating and storing tank. The hydraulic flushing equipment 99 can be used to discharge the sludge sediment into the sludge discharge tank 888, and finally the sludge sediment is discharged through the sludge discharge pipe 8 by the sludge discharge pump 88 and sent to the nearby sewage pipe network.
[0030] Therefore, this embodiment can reduce the flow rate of rainwater entering the water storage tank by providing 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.
[0031] The regulating reservoir 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 by a decanter.
[0032] Furthermore, in this embodiment, a second energy dissipation step 9081 is further provided at the end of the mud discharge trough 888, and the top of the second energy dissipation step 9081 is connected to the bottom plate of the regulating reservoir. The second energy dissipation step 9081 can reduce the flow rate of water entering the mud discharge trough 888, which is conducive to the sedimentation of sludge in the mud discharge trough 888.

Valves are provided on the first branch pipe and the second branch pipe. A regenerated water tank and a regenerated water pump are installed in the regenerated water room 909, the regenerated water tank is connected to the first branch pipe, and the regenerated water pump is provided in the regenerated water tank or beside the regenerated water tank, and is used to pump water in the regenerated water tank to the ground regenerated water filling station.
[0035] After a period of treatment, the sewage in the storage tank meets the discharge standard according to the time or water quality test. The outlet pump 77 is started to discharge the sewage into the regeneration water tank in the regeneration water room 909 through the first branch pipe. When the regeneration water tank reaches the high water level, the remaining water is discharged into the nearby river through the second branch pipe for ecological water replenishment. Disinfectant is added to the regeneration water tank to kill bacteria, and then the regeneration water pump is used to add water to the water truck for greening, cleaning, etc.
[0036] Furthermore, in this embodiment, the hydraulic flushing equipment 99 includes a submersible pump and a rotating water spray pipe connected to the submersible pump.
[0037] Furthermore, in this embodiment, a reservoir maintenance passage 901 and a submersible pump maintenance passage 9011 are provided in the reservoir.
[0038] 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.
[0039] The bioreactor module 303 includes a box body, and a support is provided at the bottom of the box body. The top and bottom of the box body are respectively provided with a top opening and a bottom opening, and a microbial filler 304 is provided inside the box body, and an aeration device 5 is provided below the microbial filler 304, and the aeration device 5 is connected to the aeration fan; 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 box body through an upper connecting piece 16 and a lower connecting piece 17; the floating filler is a heavy filler 212 or a light filler 213, and a filter plate 18 is provided in the box body, and the heavy filler 212 is filled in the box body and is located above the filter plate 18; the light filler 213 is filled in the box body and is located below the filter plate 18.
[0040] When the microbial filler 304 is directly arranged in the regulating reservoir, an aeration device 5 is arranged 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 on the upper support body 14 and the lower support body in the regulating reservoir shell 301; the floating filler is a heavy filler 212 or a light filler 213, and a filter plate 18 is arranged in the regulating reservoir shell 301. The heavy filler 212 is filled in the regulating reservoir shell 301 and is located above the filter plate 18; the light filler 213 is filled in the regulating reservoir shell 301 and is located below the filter plate 18. A filter head 50 is arranged on the filter plate 18.
[0041] 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.
[0042] 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, 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), total nitrogen and organic matter in the water are catalytically decomposed and removed by anoxic microorganisms such as denitrifying bacteria. After a period of treatment, the sewage in the regulating and storage tank meets the discharge standard according to time or water quality inspection. The outlet pump 77 is started and first discharged into the regenerated water tank in the regenerated water room 909 through the outlet pipe 7. When the regenerated water tank reaches a 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 the 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 to treat the sewage.
[0043] To ensure that total phosphorus and total nitrogen meet the standards, phosphorus removal agents such as polyaluminium 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.
[0044] De-filming and cleaning process of microbial filler 304:
[0045] The aeration fan is turned off, and the cleaning fan is started, 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 perform film removal and cleaning on the microbial filler 304 in different areas, and the aged microbial film on the biological filler is stripped into the water of the regulating and storage tank and precipitated to the bottom of the regulating and storage tank after 1-2 hours.
[0046] It should be noted that the jet hole on the cleaning air distribution device 4 has a larger aperture, and the air intake of the cleaning fan is also larger. However, the aperture on the aeration pipe is smaller, and the aeration air volume is also smaller, which cannot play an effective cleaning role.
[0047] Adaptive changes made according to actual needs are all within the protection scope of this utility model.
[0048] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
