Detailed Embodiments

[0016] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0017] Embodiment 1: This embodiment provides a block-based rainwater recycling management system, including: A rainwater receiving module 1 for receiving rainwater and drainage within the block; A filtering module 2 for filtering the rainwater received by the rainwater receiving module 1; A storage module for storing the water that has passed through the rainwater filtering module 2; The water supply distribution control module includes multiple cooperating modules, which are respectively arranged in the rainwater receiving module 1, the rainwater filtering module 2 and the storage module, and are used to control the operation of the rainwater receiving module 1, the rainwater filtering module 2 and the storage module.

[0018] In this technical solution, the block-based rainwater recycling management system can be set up based on units such as communities, residential areas, and streets, and the rainwater within the block is recycled and managed through the block-based rainwater recycling management system. Among them, the rainwater receiving module 1 is used to receive the rainwater overflowing from the roads, greenery, landscape ponds, etc. within the block, and collect the excess pond water discharged after injecting new water to keep the pond water alive when it does not rain. The filtering module 2 performs a series of filtrations on the water received by the rainwater receiving module 1, so that the filtered water can meet the water requirements for landscape ponds, greenery irrigation, and fire protection. The storage module is used to store the water filtered by the filtering module 2. The water supply distribution control module reasonably distributes the water to fire protection, landscape ponds, greenery irrigation, and public toilet cleaning according to the water storage volume in the storage module. In particular, when there is no circulating fresh water, the landscape pond is prone to emitting odors, which is not conducive to the survival of the organisms in the pond and will affect the lives of the surrounding residents. Therefore, when the storage volume in the storage module is insufficient, the water supply distribution control module gives priority to supplying fire protection, followed by supplying the landscape pond, and finally supplying greenery irrigation and public toilet cleaning.

[0019] Embodiment 2: This embodiment provides a block-based rainwater recycling management system, which has the following technical features in addition to the technical solution of the above embodiment.

[0020] The rainwater receiving module 1 includes: A road surface rainwater receiving pipeline, which is used to connect to the drainage system under the road surface within the block to receive the rainwater discharged from the road surface; A pond water receiving pipeline, which is used to connect to the water outlet of the pond within the block; Among them, two branches are formed at the end of the road surface rainwater receiving pipeline, namely a bypass branch pipeline and a return branch pipeline, and the end of the bypass branch pipeline is connected to the urban drainage system, and the return branch pipeline is connected to the filtering module 2.

[0021] In this technical solution, the road surface rainwater receiving pipeline is connected to the underground drainage channels in the block, mainly including the sewers near parks, road surfaces, and greenery, which are used to receive the rainwater flowing into the sewers in these areas. At the same time, it tries to avoid connecting to the sewers in areas with catering and cleaning industries as much as possible, so as to reduce the entry of oil stains, cleaning agents, etc. into the recycling management system. The pool water receiving pipeline is connected to the drainage channel of the landscape pond, thereby receiving the rainwater overflowing from the pond and the excess pool water discharged after injecting new water to keep the water in the pond alive. Since when it rains, the rainwater entering the underground drainage channels will carry certain foreign matters, such as leaves and sediment, when the rainwater enters the air outlet of the road surface rainwater receiving pipeline, the rainwater first directly enters the urban drainage system through the flow diversion branch pipeline without being recycled, so as to reduce the filtering burden on the filtering module 2; after the amount of foreign matters decreases, it then enters the filtering module 2 through the reflux branch pipeline for filtering.

[0022] Embodiment 3: This embodiment provides a block-based rainwater recycling management system. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0023] The filtering module 2 includes: A primary filtration tank with a primary filter screen on its upper part, and water enters the primary filtration tank through the primary filter screen; A sedimentation tank for receiving the preliminarily filtered water discharged from the primary filtration tank and sedimenting it; A sterilization tank for receiving the sedimented water discharged from the sedimentation tank and sterilizing it; A water quality conditioning tank for receiving the sterilized water discharged from the sterilization tank and performing acid-base neutralization to remove oil substances.

[0024] In this technical solution, the number of the primary filtration tank, sedimentation tank, sterilization tank, and water quality conditioning tank in the filtering module 2 is adjusted and set according to the area of the block and the annual water reduction in this area. The primary filtration tank is used to filter large particulate foreign matters in water, such as leaves, packaging bags, large particulate sediment, etc. The sedimentation tank is used to sediment the water after primary filtration, sedimenting the sediment in the water, and then sterilizing it through the sterilization tank. After sterilization, the water is then subjected to acid-base neutralization and removal of oil and other substances through the water quality conditioning tank. And a membrane filtration component can be set after the water quality conditioning tank to further filter the water adjusted by the water quality conditioning tank, so as to improve the water quality.

[0025] Embodiment 4: This embodiment provides a block-based rainwater recycling management system. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0026] The storage module includes: An emergency water tank 3 with a certain amount of emergency water stored in it for a long time; The park and public toilet water tank 4 is used to store water for supplying the park pool, greening irrigation, and public toilet cleaning.

[0027] In this technical solution, a certain amount of emergency water is stored in the emergency water tank 3 for a long time, mainly supplying water to the community and road fire hydrants in this area. The park and public toilet water tank 4 stores water for greening irrigation, park pool, and public toilet cleaning. Among them, the greening irrigation, landscape pond, and public toilet cleaning in this area are all equipped with two water supply inlet pipes. One is the water supply pipe sent from the park and public toilet water tank 4, and the other is the water supply pipe connected to the municipal water pipe. When the water volume in the park and public toilet water tank 4 is insufficient, the municipal water pipe is used to supply water for greening irrigation, landscape pond, and public toilet cleaning. And the capacity and quantity of the emergency water tank 3 and the park and public toilet water tank 4 are set according to the size of the area and the rainfall. When multiple emergency water tanks 3 and park and public toilet water tanks 4 are set, the same type of water tanks are connected in series through large-diameter pipes. And an overflow pipe is set on each of the emergency water tank 3 and the park and public toilet water tank 4, and an overflow valve is set on the overflow pipe.

[0028] Embodiment 5: This embodiment provides a block rainwater recycling management system. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0029] The water supply distribution control module includes: Receiving switching gates, which are both set at the inlets of the flow rejection branch pipeline and the reflux branch pipeline; A filter clogging detection device for detecting the clogging condition of the primary filter; A sediment thickness detection device for detecting the accumulation of sediment in the sedimentation tank; A sterilization device, which is set in the sterilization tank to sterilize the water in the sterilization tank; A water quality detection device, which includes an oil-in-water sensor and a water quality sensor, and is set in the sediment thickness detection device; A feeding device, which is set on the water quality conditioning tank for feeding agents for adjusting water quality into the water quality conditioning tank.

[0030] In this technical solution, the receiving switching gate is arranged at the inlet ends of the flow diversion branch pipeline and the return flow branch pipeline. When the rainwater stored in the rainwater storage enters the road surface rainwater receiving pipeline, first open the receiving switching gate on the flow diversion branch pipeline to avoid collecting the rainwater with more debris in the early stage. After a period of time, then close the receiving switching gate on the flow diversion branch pipeline and open the receiving switching gate on the return flow branch pipeline, so that the rainwater enters the filtering module 2 through the receiving switching gate. The filter clogging detection device can be a visual detection device, which detects the clogging condition of the filter by detecting the situation of the initial filter being blocked by foreign objects. The bottom sediment thickness detection device can be a laser detection device, which is used to detect the thickness of the sediment at the bottom of the sedimentation tank. The sterilization device is an ultraviolet sterilizer, which is arranged at the bottom of the sterilization tank to sterilize the water. The water quality detection device is used to detect the water condition in the water quality conditioning tank, including the acidity and alkalinity, oil content, etc.; then corresponding substances are put in through the feeding device to neutralize the acid-base or adsorb the oil, so as to ensure the water quality of the water transported to the storage module.

[0031] Embodiment 6: This embodiment provides a block-based rainwater recycling management system. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0032] The water supply distribution control module further includes: An emergency delivery pump 5, which is used to pump the water in the emergency water tank 3 out; A park pool delivery pump 6, which is used to pump the water in the park and public toilet water tank 4 out to supply the park pool; A park irrigation delivery pump 8, which is used to pump the water in the park and public toilet water tank 4 out to supply the park greening irrigation; A public toilet water supply delivery pump 9, which is used to pump the water in the park and public toilet water tank 4 out for toilet cleaning; Several liquid level detectors, which respectively detect the real-time water storage capacity of the emergency water tank 3 and the park and public toilet water tank 4; An emergency external delivery pump 10, which is used to transport the water in the emergency water tank 3 to the park and public toilet water tank 4; An emergency reverse supplement pump 11, which is used to supplement the water in the park and public toilet water tank 4 to the emergency water tank 3; A control cabinet, which is internally provided with a communicator, a controller and a control circuit.

[0033] In this technical solution, the emergency transfer pump 5 is a fire pump, and multiple ones can be set. The inlet end of each fire pump is connected to an emergency water tank 3 through a pipeline, and the outlet end is connected to the corresponding fire hydrant through a pipeline. Multiple park irrigation transfer pumps 8 can be set. The inlet end of each park irrigation transfer pump 8 is connected to a park and public toilet water tank 4 through a pipeline, and the outlet end is connected to the water supply pipeline for the corresponding park irrigation. Multiple park pond transfer pumps 6 can be set. The inlet end of each park pond transfer pump 6 is connected to a park and public toilet water tank 4 through a pipeline, and the outlet end is connected to the water supply pipeline for the corresponding park pond. Multiple public toilet water supply transfer pumps 9 can be set. The inlet end of each public toilet water supply transfer pump 9 is connected to a park and public toilet water tank 4 through a pipeline, and the outlet end is connected to the water supply pipeline for the corresponding public toilet cleaning water supply. The liquid level detector is used to detect the real-time liquid level in each water tank, so as to detect the water capacity in the storage module. When the water in the park and public toilet water tank 4 is insufficient, the emergency external pump 10 pumps a part of the water in the emergency water tank 3 into the park and public toilet water tank 4. When the water in the emergency water tank 3 is insufficient and does not meet the fire demand, the emergency reverse supplement pump 11 pumps the water in the park and public toilet water tank 4 into the emergency water tank 3. The communicator can be used to receive weather forecasts and send maintenance messages to the management personnel, such as the initial filter screen being blocked, silt accumulation in the sedimentation tank, etc.; then, through the cooperation of the controller and the control circuit, the operation of the block rainwater recycling management system is controlled.

[0034] Embodiment 7: This embodiment provides a management control method for a block rainwater recycling management system. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0035] Including: Step I, obtaining the current total water storage volume by monitoring the water storage situation of each water tank in the storage module in real time; Step II, determining the future total water storage pre-collection volume according to the weather conditions in the future weather forecast, such as sunny or cloudy, temperature, whether it rains, rainfall, etc., and the area of ponds, road surface area, greening area and their proportions in this area; Step III, determining the future total water storage collectable volume according to the future total water storage pre-collection volume and the collection deviation coefficient during the collection process; Step IV, obtaining the future storage volume according to the future total water storage collectable volume and the current total water storage volume in the storage module; Step V, adjusting the water supply distribution situation during the current to future time period according to the future storage volume of the storage module; Step VI, calculating the pre-water consumption during the current to future time period according to the water supply distribution situation during the current to future time period.

[0036] In this technical solution, in step I, the current total water storage of the storage module is detected by first detecting the total water storage of the emergency water tank 3 and the water tanks 4 in parks and public toilets respectively, and then obtaining the current total water storage of the detection module.

[0037] In step II, due to different temperatures and weather conditions, and different areas of ponds, roads and green spaces, the evaporation rate of water and the absorption rate of rainwater will be affected, resulting in different amounts of rainwater that can be collected. First, the areas of ponds, green spaces and roads in this area are pre-input into the controller. At the same time, deviation values of water collection amounts under different temperatures and weather conditions are set, so as to correct the total pre-collected water storage. The road area can include areas far from residential buildings and garbage recycling stations in the community. The total pre-collected water storage can be a positive number, such as rainwater collected during rain and the pool water discharged when maintaining the live water circulation in the landscape pond; the total pre-collected water storage can also be a negative number, that is, when there is no rain and the landscape pond has no live water circulation and discharges pool water. However, the total pre-collected water storage should be a positive number under normal weather conditions, because even when there is no rain, the pool water still needs to maintain live water circulation, and as long as new water is injected, pool water will be discharged. The future weather conditions are the weather forecast data six hours after running this step.

[0038] In step III, the collection deviation coefficient is corrected every time rain is collected, so as to better obtain the accuracy of the total amount of rainwater that can be collected, and at the same time, the collection amount of pool water under different temperatures and weather conditions when there is no rain will also be continuously corrected.

[0039] In step IV, the future storage amount in the storage module can be more accurately determined by calculating the sum of the total amount of water that can be stored, the pre-consumption of water used, and the current total water storage in the storage module.

[0040] In step V, the water supply distribution situation during the current to future time period is adjusted according to the future storage amount in the storage module. If the water volume is sufficient, it can be supplied to fire fighting, public toilet cleaning, greening irrigation and park pools; if the water volume is small, it can be supplied to fire fighting and park pools; if the water volume is insufficient, it can only be supplied to fire fighting. And the future storage amount does not exceed the total water storage of the storage module. When the sum of the total amount of water that can be stored, the pre-consumption of water used, and the current total water storage in the storage module is greater than the maximum capacity of the storage module, a part of the rainwater is discharged through the bypass pipeline during rainwater collection.

[0041] In step VI, the pre-consumption of water used from the current to the future is calculated based on the water supply distribution situation from the current to the future time period, and then this pre-consumption of water used is applied in step VI in the next cycle, so as to ensure that the future storage amount obtained in step IV is more accurate. And the cycle frequency of the above control steps is 10 - 30 min / time.

[0042] Embodiment 8: This embodiment provides a management control method for a block rainwater recycling management system. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0043] Determining the total pre-collection volume of water storage in step II includes: Step II-I: Preset the pond area, road surface area, and greening area in this area, and set the absorption amount of rainwater and the evaporation amount of rainwater by the pond, road surface, and greening under different weather conditions, different rainfall amounts, and different temperatures in the same unit time. Step II-II: According to the weather forecast, read the total rainfall amount, the absorption amount of water, and the evaporation amount of water of the pond, road surface, and greening in this area under the corresponding conditions, and comprehensively determine the water overflow amount. The total pre-collection volume of water storage is obtained according to this water overflow amount in proportion. Determining the total future water storage collectable volume in step III includes: Step III-I: According to the water recovery rates of the preset road surface rainwater receiving pipeline and the pond water receiving pipeline under different weather conditions, temperatures, and rainfall amounts, determine the total water storage collectable volume according to this water recovery rate and the total pre-collection volume of water storage. Step III-II: Compare the total water storage collectable volume under different weather conditions, temperatures, and rainfall amounts with the actual total water storage collection volume in history under different weather conditions, temperatures, and rainfall amounts to obtain the collection deviation coefficient. Step III-III: Obtain the total water storage collectable volume according to the total pre-collection volume of water storage and the collection deviation coefficient. Among them, if there is no collection deviation coefficient under the corresponding weather conditions, temperatures, and rainfall amounts in history, the total water storage collectable volume is the total water storage collectable volume.

[0044] In this technical solution, in step II-I, the water absorption rates of the road surface and greening are also comprehensively corrected in combination with the situation of the previous rainfall and the interval time. For example, if the time since the previous rainfall is too long or the rainfall amount is small, the absorption amount of rainwater by the road surface and greening will increase. And because step II-I sets the absorption amount of rainwater and the evaporation amount of water by the pond and greening under different weather conditions, different rainfall amounts, and different temperatures, such as when the temperature is high, the evaporation amounts of the pond, road surface, and greening will increase, and the water absorption amount will also fluctuate appropriately. Then, according to the rainfall rate and rainfall amount of this block in the weather forecast, combined with the absorption amount and evaporation amount of rainwater by the greening, pond, and road surface area, the water overflow amount of this area is determined. 60%-80% of the water overflow amount is the total pre-collection volume of water storage.

[0045] In Step III, the water recovery rate is due to the losses caused by water passing through pipelines, the filtration module 2, etc. Therefore, the water recovery rate is preset and this part of the loss is subtracted to determine the total amount of water that should be collected in the reservoir. Due to the influence of road surface potholes, the set absorption amount, evaporation amount, etc., the total amount of water that should be collected in the reservoir is not equal to the total amount of water that can be collected in the reservoir. Therefore, the historical true situation of rainwater collection under corresponding weather, temperature, and rainfall conditions is compared to determine the collection deviation coefficient, and then the total amount of water that can be collected in the reservoir is further corrected, thereby improving the accuracy of rainwater collection detection.

[0046] Example 9: This embodiment provides a management control method for a block rainwater recovery management system. In addition to including the technical solutions of the above embodiments, it also has the following technical features.
