Description

Technical Field

[0001] The present application relates to the field of municipal engineering technology, and in particular to a municipal rainwater treatment device and a method of use. Background Art

[0002] As cities expand, hardened ground continues to increase, and rainwater runoff also increases. If not effectively treated, a large amount of rainwater will gather in a short period of time, which may cause urban waterlogging and pose a serious threat to people's lives and property. Municipal rainwater treatment is an indispensable part of urban sustainable development. It is not only related to the city's flood control safety, but also of great significance to the protection of the ecological environment. Untreated rainwater may carry various pollutants, such as sediment, garbage, chemicals, etc., which will pollute and damage the ecosystems such as rivers and lakes when directly discharged into natural water bodies. Through treatment, these pollutants can be removed, the health and stability of the water ecology can be protected, and the balance of the urban ecosystem can be maintained.

[0003] At present, when treating municipal rainwater, it is usually necessary to first use rainwater pipe networks, drainage ditches and other facilities to collect rainwater from the ground. In the process of collecting rainwater, physical filtering devices such as filters and grilles are used to remove larger impurities and particles. The rainwater is then allowed to stay in a sedimentation tank or sedimentation well for a period of time to allow heavier particles to settle to the bottom. Finally, the rainwater is disinfected and killed to kill possible germs before it can be recycled. However, before it rains, a large amount of dust, particles, garbage and various pollutants in automobile exhaust will accumulate on the surfaces of urban roads and roofs. These pollutants will be washed into the rainwater during rainfall, resulting in a large amount of pollutants in the rainwater at the beginning of rainfall. It is difficult to effectively separate the heavily polluted rainwater at the beginning of rainfall during the existing municipal rainwater treatment. After the heavily polluted rainwater enters the treatment system, it will undoubtedly increase the difficulty and cost of rainwater treatment.

[0004] Therefore, how to effectively separate the heavily polluted rainwater in the early stage of rainfall is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0005] In order to effectively separate seriously polluted rainwater in the early stage of rainfall, the present application provides a municipal rainwater treatment device and a method of use.

[0006] The municipal rainwater treatment device and use method provided in this application adopt the following technical solutions: In a first aspect, a municipal rainwater treatment device comprises a rainwater collection well, wherein a water inlet is arranged at the upper end of the rainwater collection well, a filter assembly is arranged inside the rainwater collection well corresponding to the water inlet, a separation box slidably connected to the side wall of the rainwater collection well is arranged below the filter assembly, a first spring is abutted and connected between the separation box and the bottom surface of the rainwater collection well, the upper end of the first spring is fixedly connected to the separation box, the lower end of the first spring is fixedly connected to the bottom surface of the rainwater collection well, a first drain outlet is arranged on the rainwater collection well, and when the first spring pushes the separation box to the upper limit position, the side wall of the separation box blocks the first drain outlet.

[0007] By adopting the above technical solution, the separation box can be used to hold rainwater entering the rainwater collection well at the beginning of rain. After the heavily polluted rainwater enters the separation box, the weight of the separation box will be increased, thereby compressing the first spring, causing the separation box to slide downward. After the separation box slides downward, the first drain port will be opened, so that rainwater in the later stage of rain can be discharged through the first drain port. When the separation box slides downward to the extreme position, a sedimentation area will be formed between the top of the separation box and the first drain port, and heavier particles will be precipitated on the top of the separation box. In this way, the heavily polluted rainwater at the beginning of rainfall is effectively separated, and the difficulty and cost of rainwater treatment are avoided after the heavily polluted rainwater enters the treatment system.

[0008] Preferably, a box cover is fixedly connected to the top of the separation box, and a plurality of first water inlet grooves are provided on the box cover; a separation plate is sealingly and slidably connected to the box cover, and a second water inlet groove is provided on the separation plate corresponding to the first water inlet groove, and the spacing between two adjacent second water inlet grooves is D, and the width of the slot of the first water inlet groove is d, satisfying D>d.

[0009] By adopting the above technical scheme, utilizing the sealed sliding connection between the box cover and the separation plate, when the separation plate is slid to align the first water inlet trough and the second water inlet trough with each other, rainwater that is severely polluted in the early stage can be allowed to enter the interior of the separation box through the first water inlet trough and the second water inlet trough. When the separation plate is slid to stagger the first water inlet trough and the second water inlet trough with each other, rainwater in the later stage of rain can be prevented from entering the interior of the separation box through the first water inlet trough and the second water inlet trough, thereby further improving the effect of separating rainwater that is severely polluted in the early stage of rainfall.

[0010] Preferably, a second spring is abutted between one end of the separation plate and the box cover, and the other end of the separation plate is slidably abutted with the side wall of the rainwater collection well, and a slope is provided on the side wall where the rainwater collection well and the separation plate are abutted at a height corresponding to the first drain outlet.

[0011] By adopting the above technical solution, the second spring can be used to enable the separation plate to automatically slide to a state where the first water inlet trough and the second water inlet trough are aligned with each other when not affected by external force. When heavily polluted rainwater enters the separation box at the initial stage of rainfall, the separation box slides downward after the gravity increases. While the separation box slides downward, the separation plate will squeeze the second spring and slide into the box cover under the action of the inclined surface, thereby causing the first water inlet trough and the second water inlet trough to be staggered with each other, thereby achieving automatic separation of heavily polluted rainwater at the initial stage of rainfall.

[0012] Preferably, an electric control valve is installed below the separation box, the electric control valve is a normally closed type, and a second drain outlet is opened at the bottom of the rainwater collection well, and the second drain outlet is connected to the separation box through the electric control valve.

[0013] By adopting the above technical solution, the heavily polluted rainwater that enters the separation box at the initial stage of rainfall can be discharged from the second drain outlet by means of an electric control valve after the rainfall stops. After the heavily polluted rainwater at the initial stage of rainfall is discharged, the gravity of the separation box will decrease, and under the action of the first spring, the separation box will slide upward and allow the separation plate to pass through the inclined plane again, so that the first water inlet trough and the second water inlet trough are aligned with each other again, so as to facilitate automatic processing during the next rainfall.

[0014] Preferably, a water quality detector is provided below the filter assembly, and the water quality detector is electrically connected to the electric control valve through a controller.

[0015] By adopting the above technical solution, the rainwater flowing through the filter component can be detected in real time using a water quality detector. If the water pollution level of the rainwater exceeds the set range, the controller controls the electric control valve to open. When the water pollution level of the rainwater is lower than the set range, the controller controls the electric control valve to close. In this way, the rainwater that provides gravity to the separation box becomes rainwater with a water pollution level lower than the set range, thereby preventing the amount of severely polluted rainwater in the early stage of rainfall from exceeding the storage capacity of the separation box, resulting in incomplete separation of the severely polluted rainwater in the early stage of rainfall and discharge through the first drain outlet.

[0016] Preferably, a water collecting hopper fixedly installed inside the rainwater collection well is provided below the filter assembly, the water quality detector is fixedly installed on the water collecting hopper, a water turbine generator is provided at the water outlet of the water collecting hopper, the water turbine generator is connected to a battery, and the battery is electrically connected to the controller.

[0017] By adopting the above technical solution, the potential energy of falling rainwater can be converted into electrical energy using a hydro-generator, and provide electrical energy supplement for livestock batteries, thereby avoiding the increase in costs caused by the use of an external power supply during the operation of the controller.

[0018] Preferably, the filter assembly includes a filter bucket, which is provided with a plurality of evenly distributed filter holes corresponding to the water inlet, a sliding seat is fixedly connected to the inner wall surface of the rainwater collection well, a sliding rod is slidably connected inside the sliding seat, and the upper end of the filter bucket is rotatably connected to the upper end of the sliding rod.

[0019] By adopting the above technical solution, the filter holes on the filter bucket can be used to conveniently filter rainwater entering the filter bucket, and the sliding connection between the sliding seat and the sliding rod can more stably, conveniently and quickly remove the filter bucket from the rainwater collection well, and the rotating connection between the upper end of the filter bucket and the upper end of the sliding rod can be used to flip the filter bucket, thereby pouring out impurities and particulate matter filtered out of the filter bucket.

[0020] Preferably, a handle is fixedly connected to the top of the filter bucket, and a guide plate arranged obliquely outward is fixedly connected between the handle and the inner side surface of the filter bucket, and the guide plate is made of a flexible material with a certain structural strength.

[0021] By adopting the above technical scheme, the handle can not only be used to lift the filter bucket more conveniently and quickly, but also the filter bucket can be rotated after lifting the filter bucket, so as to conveniently pour out the impurities and particulate matter filtered out from the inside of the filter bucket, and while pouring out the impurities and particulate matter, the guide plate can not only prevent the impurities and particulate matter from colliding with the handle, but also guide the impurities and particulate matter accurately into the recycling cart and other devices for collecting impurities and particulate matter. On the other hand, the guide plate can also guide rainwater during use to prevent rainwater from washing the handle.

[0022] Preferably, the upper end of the rainwater collection well is fixedly connected to a manhole cover seat, the manhole cover seat is rotatably connected to a manhole cover, and the manhole cover is hollowed out and designed with anti-slip patterns.

[0023] By adopting the above technical solution, the manhole cover seat and the manhole cover are arranged at the upper end of the rainwater collection well. On the one hand, it can prevent passers-by or vehicles from falling into the rainwater collection well. On the other hand, it can also allow rainwater to enter the interior of the rainwater collection well from the manhole cover, thereby improving the efficiency of rainwater collection.

[0024] In a second aspect, a method for using a municipal rainwater treatment device comprises the following steps: S1. Bury the rainwater collection well at a suitable location under the ground; at the same time, connect the water inlet to an external rainwater collection facility, connect the first drainage outlet to a rainwater disinfection facility, and connect the second drainage outlet to an external wastewater treatment facility; S2. Clean and maintain the filter assembly after use; first open the manhole cover, then lift the filter bucket upwards by the handle, lift the filter bucket to an appropriate height, and then rotate the filter bucket to pour out the impurities and particles filtered out from the inside of the filter bucket.

[0025] By adopting the above technical scheme, the rainwater collection well is buried at a suitable position under the ground, which can not only save the space above the ground occupied by the municipal rainwater treatment device during use, but also make use of the gravity of rainwater to flow downward, avoiding the energy consumed by using water pumps to extract; the first drain outlet is connected to the rainwater disinfection facility, so that rainwater with less pollution in the later stage of rain can enter the rainwater disinfection facility through the first drain outlet for disinfection; the second drain outlet is connected to the external wastewater treatment facility, so that rainwater with serious pollution in the early stage of rainfall can be collected and centrally treated, thereby preventing rainwater with serious pollution in the early stage of rainfall from polluting the environment again.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: Through ingenious structural design, the present application can automatically complete filtering, isolation and sedimentation during the process of collecting rainwater. The separation box can be used to hold rainwater entering the rainwater collection well at the initial stage of rain. After the heavily polluted rainwater enters the separation box, the weight of the separation box will increase, thereby compressing the first spring to make the separation box slide downward. After the separation box slides downward, the first drain port will be opened, so that rainwater in the later stage of rain can be discharged through the first drain port. This effectively separates the heavily polluted rainwater at the initial stage of rainfall, and avoids the increase in difficulty and cost of rainwater treatment after the heavily polluted rainwater enters the treatment system.

[0027] The present application utilizes the sealed sliding connection between the box cover and the separation plate, and can slide the separation plate to align the first water inlet trough and the second water inlet trough with each other or staggered with each other. When the first water inlet trough and the second water inlet trough are aligned with each other, rainwater that is severely polluted in the early stage can be allowed to enter the interior of the separation box through the first water inlet trough and the second water inlet trough; when the first water inlet trough and the second water inlet trough are staggered with each other, rainwater in the later stage of rain can be prevented from entering the interior of the separation box through the first water inlet trough and the second water inlet trough, thereby further improving the effect of separating rainwater that is severely polluted in the early stage of rainfall.

[0028] The present application arranges a second spring and an inclined plane at both ends of the separation plate respectively, and utilizes the second spring to enable the separation plate to automatically slide to a state where the first water inlet trough and the second water inlet trough are aligned with each other when not acted upon by an external force. When heavily polluted rainwater enters the separation box at an early stage of rainfall, the separation box slides downward after the gravity increases. While the separation box slides downward, the separation plate will squeeze the second spring and slide into the box cover under the action of the inclined plane, thereby causing the first water inlet trough and the second water inlet trough to be staggered with each other, thereby achieving automatic separation of heavily polluted rainwater at an early stage of rainfall.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] The embodiments of the present application disclose a municipal rainwater treatment device and a method of use.

[0041] Please refer to Figure 1 In one embodiment of the present application, a municipal rainwater treatment device includes a rainwater collection well 100. The rainwater collection well 100 can be made of a brick-concrete structure or can be assembled and installed in the form of prefabricated concrete components. A water inlet 200 is arranged at the upper end of the rainwater collection well 100. The water inlet 200 can be arranged at the top of the rainwater collection well 100 or at the side of the rainwater collection well 100 near its top. A manhole cover seat 800 is fixedly connected to the upper end of the rainwater collection well 100. A manhole cover 801 is rotatably connected to the manhole cover seat 800. The manhole cover 801 is hollowed out and has anti-slip patterns 802. By setting the manhole cover seat 800 and the manhole cover 801, on the one hand, pedestrians or vehicles passing by can be prevented from falling into the rainwater collection well 100. On the other hand, rainwater can also enter the interior of the rainwater collection well 100 from the manhole cover 801, so that the water intake of the rainwater collection well 100 when collecting rainwater can be increased, and the efficiency of rainwater collection can be improved. A first drain outlet 500 is provided on the side of the rainwater collection well 100 near the middle thereof, and is used to discharge rainwater in the later stage of rain. A second drain outlet 600 is provided on the side of the rainwater collection well 100 near the bottom thereof, and is used to discharge rainwater that is severely polluted in the initial stage.

[0042] Please refer to Figure 2 and Figure 4 In one embodiment of the present application, a filter assembly 300 is provided inside the rainwater collection well 100 corresponding to the water inlet 200, and the filter assembly 300 includes a filter bucket 301, the upper end of the filter bucket 301 is designed to be open and its bottom surface is set as an inclined surface, and evenly distributed filter holes 302 are opened on the inclined surface corresponding to the water inlet 200 and the manhole cover 801 of the rainwater collection well 100. Providing the filter holes 302 on the inclined surface can increase the number of the filter holes 302 on the one hand, and prevent the filter holes 302 from being blocked by impurities and particulate matter on the other hand, thereby ensuring the filtering effect.

[0043] Please refer to Figure 2 and Figure 4 In one embodiment of the present application, a sliding seat 303 is fixedly connected to the inner wall of the rainwater collection well 100, a sliding rod 304 is slidably connected inside the sliding seat 303, and the upper end of the filter bucket 301 is rotatably connected to the upper end of the sliding rod 304. The filter hole 302 on the filter bucket 301 can conveniently filter the rainwater entering the filter bucket 301, and the sliding connection between the sliding seat 303 and the sliding rod 304 can more stably and conveniently move the filter bucket 301 out of the rainwater collection well 100. At the same time, the rotation connection between the upper end of the filter bucket 301 and the upper end of the sliding rod 304 can be used to flip the filter bucket 301, and then pour out the impurities and particulate matter filtered out of the filter bucket 301.

[0044] Please refer to Figure 2 and Figure 3 In one embodiment of the present application, a separation box 400 is provided below the filter assembly 300 and is slidably connected to the side wall of the rainwater collection well 100. A first spring 401 is abutted against the bottom surface of the separation box 400 and the rainwater collection well 100. The upper end of the first spring 401 is fixedly connected to the separation box 400, and the lower end of the first spring 401 is fixedly connected to the bottom surface of the rainwater collection well 100. When the first spring 401 pushes the separation box 400 to the upper limit position, the side wall of the separation box 400 blocks the first drain outlet 500.

[0045] like Figure 4 As shown, the separation box 400 can be used to contain rainwater entering the rainwater collection well 100 at the initial stage of rain. After the heavily polluted rainwater enters the separation box 400, the weight of the separation box 400 will be increased, thereby compressing the first spring 401, causing the separation box 400 to slide downward. After the separation box 400 slides downward, the first drain port 500 will be opened, so that rainwater in the later stage of rain can be discharged through the first drain port 500, effectively separating the heavily polluted rainwater at the initial stage of rain, and avoiding the increase in difficulty and cost of rainwater treatment after the heavily polluted rainwater enters the treatment system.

[0046] like Figure 6As shown, when the separation box 400 slides downward to the limit position, a sedimentation area is formed between the top of the separation box 400 and the first drainage port 500, and heavier particles are precipitated on the top of the separation box 400. In this way, after the rainwater in the late rainfall period is precipitated, the purity of the rainwater discharged from the first drainage port 500 can be improved, so that the rainwater can be disinfected.

[0047] Please refer to Figure 4 and Figure 5 In a specific embodiment of the present application, in order to improve the separation effect of severely polluted rainwater in the early stage of rainfall, a box cover 402 is fixedly connected to the top of the separation box 400, and a plurality of first water inlet grooves 403 are opened on the box cover 402; a separation plate 404 is sealingly and slidably connected to the box cover 402, and a second water inlet groove 405 is opened on the separation plate 404 corresponding to the first water inlet groove 403, and the distance between two adjacent second water inlet grooves 405 is D, and the width of the slot of the first water inlet groove 403 is d, satisfying D>d. By utilizing the sealed sliding connection between the box cover 402 and the separation plate 404, when the sliding separation plate 404 aligns the first water inlet groove 403 and the second water inlet groove 405 with each other, rainwater that is severely polluted in the early stage can be allowed to enter the separation box 400 through the first water inlet groove 403 and the second water inlet groove 405. When the sliding separation plate 404 staggers the first water inlet groove 403 and the second water inlet groove 405, rainwater in the later stage of rain can be prevented from entering the separation box 400 through the first water inlet groove 403 and the second water inlet groove 405, thereby further improving the effect of separating rainwater that is severely polluted in the early stage of rainfall.

[0048] Please refer to Figure 4 and Figure 5 In a specific embodiment of the present application, a second spring 406 is connected between one end of the separation plate 404 and the box cover 402, and the other end of the separation plate 404 is connected to the side wall of the rainwater collection well 100 in a sliding manner. A slope 407 is provided on the side wall of the rainwater collection well 100 and the separation plate 404 at a height corresponding to the first drain port 500. By using the second spring 406, the separation plate 404 can automatically slide to a state where the first water inlet groove 403 and the second water inlet groove 405 are aligned with each other when no external force is applied. When the heavily polluted rainwater enters the separation box 400 at the initial stage of rainfall, the separation box 400 slides downward after the gravity increases. When the separation box 400 slides downward, the separation plate 404 will squeeze the second spring 406 and slide into the box cover 402 under the action of the slope 407, thereby making the first water inlet groove 403 and the second water inlet groove 405 staggered with each other, so that the heavily polluted rainwater at the initial stage of rainfall can be automatically separated.

[0049] Please refer to Figure 4 and Figure 6In a specific embodiment of the present application, in order to further improve the effect of settling rainwater, a plurality of vertically arranged chutes 501 are provided on the side walls of the rainwater collection well 100, and a partition 502 is slidably connected inside the chutes 501. The surface of the partition 502 is arranged parallel to the side of the rainwater collection well 100 on which the first drain port 500 and the second drain port 600 are provided, and the bottom of the partition 502 abuts against the box cover 402 on the top of the separation box 400, so that the up and down movement of the separation box 400 can drive the partition 502 to move up and down. The setting of the partition 502 can reduce the fluidity of rainwater in the sedimentation area, thereby ensuring the effect of settling rainwater.

[0050] Please refer to Figure 4 and Figure 5 In a specific embodiment of the present application, an electric control valve 408 is installed below the separation box 400. The electric control valve 408 is a normally closed type. The second drain port 600 can be connected to the separation box 400 through the electric control valve 408. By using the electric control valve 408, the rainwater with severe pollution at the initial stage of rainfall that enters the separation box 400 can be discharged from the second drain port 600 after the rainfall stops. After the rainwater with severe pollution at the initial stage of rainfall is discharged, the gravity of the separation box 400 will decrease. Under the action of the first spring 401, the separation box 400 will slide upward and make the separation plate 404 pass through the inclined surface again, so that the first water inlet trough 403 and the second water inlet trough 405 are aligned with each other again, so as to facilitate automatic processing during the next rainfall.

[0051] Please refer to Figure 4 and Figure 6 In a specific embodiment of the present application, a water quality detector 700 is provided below the filter assembly 300, and the water quality detector 700 and the electric control valve 408 are electrically connected to a controller 704. The water quality detector 700 can be used to detect rainwater flowing through the filter assembly 300 in real time. If the water quality pollution degree of the rainwater exceeds the set range, the electric control valve 408 is controlled to open by the controller 704. When the water quality pollution degree of the rainwater is lower than the set range, the electric control valve 408 is controlled to close by the controller 704. In this way, the rainwater that provides gravity for the separation box 400 becomes rainwater with a water quality pollution degree lower than the set range, thereby preventing the amount of seriously polluted rainwater in the early stage of rainfall from exceeding the storage capacity of the separation box 400, resulting in incomplete separation of seriously polluted rainwater in the early stage of rainfall and discharge through the first drain port 500.

[0052] Please refer to Figure 4 and Figure 6In a specific embodiment of the present application, a water collecting bucket 701 fixedly installed inside the rainwater collecting well 100 is provided below the filter assembly 300, a water quality detector 700 is fixedly installed on the water collecting bucket 701, a water turbine generator 702 is provided at the water outlet of the water collecting bucket 701, the water turbine generator 702 is connected to a battery 703, and the battery 703 is electrically connected to the controller 704. By using the water turbine generator 702, the potential energy of falling rainwater can be converted into electrical energy, and the battery 703 can be supplemented with electrical energy, thereby avoiding the increase in cost caused by the use of an external power supply by the controller 704 during operation.

[0053] Please refer to Figure 4 and Figure 7 In a specific embodiment of the present application, a handle 305 is fixedly connected to the top of the filter bucket 301, and a guide plate 306 is fixedly connected between the handle 305 and the inner side of the filter bucket 301 and is obliquely arranged outward. The guide plate 306 is made of a flexible material with a certain structural strength. The handle 305 can not only lift the filter bucket 301 more conveniently and quickly, but also rotate the filter bucket 301 after lifting the filter bucket 301, so as to conveniently pour out the impurities and particles filtered out of the filter bucket 301, and while pouring out the impurities and particles, the guide plate 306 can not only prevent the impurities and particles from colliding with the handle 305, but also guide the impurities and particles to accurately enter the recycling cart and other devices for collecting impurities and particles. On the other hand, the guide plate 306 can also guide rainwater during use to prevent rainwater from washing the handle 305.

[0054] A method for using a municipal rainwater treatment device comprises the following steps: S1. The rainwater collection well 100 is buried at a suitable position under the ground. The rainwater collection well 100 is buried at a suitable position under the ground. The municipal rainwater treatment device can occupy the space above the ground during use, and the gravity of the rainwater can be used to flow downward, avoiding the energy consumed by using a water pump to extract. At the same time, the water inlet 200 is connected to an external facility for collecting rainwater, and the first drain outlet 500 is connected to a facility for disinfecting rainwater. The first drain outlet 500 is connected to a facility for disinfecting rainwater, so that rainwater with less pollution in the later stage of rain can enter the facility for disinfecting rainwater through the first drain outlet 500 for disinfection; the second drain outlet 600 is connected to an external facility for treating wastewater, and the second drain outlet 600 is connected to an external facility for treating wastewater, so that rainwater that is severely polluted in the early stage of rainfall can be collected and centrally treated, thereby preventing rainwater that is severely polluted in the early stage of rainfall from polluting the environment again.

[0055] S2. Clean and maintain the filter assembly 300 after use; first open the manhole cover 801, then lift the filter bucket 301 upwards by the handle 305, lift the filter bucket 301 to a suitable height, and then rotate the filter bucket 301 to pour out the impurities and particles filtered out of the filter bucket 301. Figure 7 As shown, the trolley 900 for carrying impurities and particles is placed on the ground next to the rainwater collection well 100, so that the impurities and particles poured out from the filter bucket 301 can directly enter the trolley 900. After cleaning, the filter bucket 301 is put back into the rainwater collection well 100 and the well cover is closed. This design is not only easy to operate, but also has the advantages of saving time and effort.
