Description

Technical Field

[0001] This invention relates to the field of water resource management technology, and in particular to a method and system for water environment management in areas with abundant water resources. Background Technology

[0002] In recent years, with the continuous growth of urban areas and the surge in population during urbanization, the space for waterways within polder areas has been constantly encroached upon and squeezed. Furthermore, the indiscriminate placement of drainage outlets from above-ground buildings into these waterways has caused severe water pollution. Current water pollution control methods within polder areas, whether in water-scarce or water-abundant regions, employ a uniform approach: relying on ecological water replenishment for waterways and addressing both forward and reverse source tracing of drainage outlets. This uniform approach is rather crude and fails to fully utilize the natural laws governing water resources, resulting in low efficiency and high energy consumption in water resource management in water-abundant areas. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a water environment management method and system for water-rich areas, which can effectively utilize the water resource characteristics of water-rich areas, thereby improving the efficiency of water resource management in water-rich areas and reducing the energy consumption of water resource management in water-rich areas.

[0011] Furthermore, the water environment data includes river water data; the preset water pollution threshold includes a preset river water pollution threshold; after the step of dividing the polder area to be treated into at least one water pollution area based on the water environment data and the preset water pollution threshold, the method further includes: determining whether the river water data below the preset river water pollution threshold is below the preset high pollution threshold; if so, determining the water pollution area as a key black and odorous area; if not, determining the water pollution area as a lightly polluted area.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0034] Example 1:

[0035] Figure 1 This is a flowchart of a water environment management method for water-rich areas provided in Embodiment 1 of the present invention.

[0036] Reference Figure 1 Water environment management methods in water-rich areas include:

[0037] Step S101: Obtain water environment data within the polder area to be treated.

[0038] Here, the water-rich areas mainly refer to the delta areas formed by river estuaries. The terrain is flat, with small overall elevation differences, high groundwater levels, and abundant river water resources.

[0039] A polder is a low-lying, flood-prone area in plains, river networks, or along rivers and lakes. It is a closed flood control and drainage protection area formed by building dikes, sluice gates, and pumping stations to defend against floods from the outside and drain water from the inside.

[0040] Water environment data includes river and canal water data and drainage pipe data. River and canal water data includes long-term (e.g., one month or more) and short-term (e.g., the last 5 days) water quality monitoring data for river and canal sections. Drainage pipe data includes water volume and water quality data for each drainage pipe, which includes sewage pipes and stormwater pipes. Water quality data can be BOD5 (Biochemical Oxygen Demand in Water).

[0041] Step S102: Based on water environment data and preset water pollution thresholds, the polder area to be treated is divided into at least one water pollution area; the water pollution area is the area where the water environment data is higher than the water pollution threshold.

[0042] Here, the preset water pollution threshold is set in advance according to the actual situation, and it can be the BOD5 threshold.

[0043] If the BOD5 level in the current pipeline is higher than the BOD5 threshold, it indicates that the concentration of organic matter in the water in the current pipeline is high. When microorganisms decompose these organic matter, they consume a large amount of dissolved oxygen. The oxygen in the water may be rapidly depleted, leading to oxygen deficiency or even death of aquatic organisms. Therefore, the current pipeline is contaminated with water.

[0044] If the current BOD of the pipeline is lower than or equal to the BOD5 threshold, it indicates that the concentration of organic matter in the water in the pipeline is low, the microorganisms consume less oxygen, and the water body has a strong self-purification capacity. This usually means that the water quality is good, the pollution is light, or there is no obvious pollution.

[0045] Each water-polluted pipe within a preset geographical area will be integrated into a water pollution zone, where the preset geographical area is pre-set based on actual conditions.

[0046] Step S103: Determine whether the water pollution area is a high-density built-up area.

[0047] Here, high-density built-up areas refer to densely populated and building-rich areas within pre-planned polder areas slated for remediation. These areas are characterized by a large population, high population density, and a large number and concentration of buildings, resulting in high building density. They typically include various residential, commercial, and industrial buildings. Furthermore, high-density built-up areas typically have well-developed and complex infrastructure, such as roads, pipelines, electricity, water supply, and drainage systems. Land utilization is high, and open space is relatively limited.

[0048] Step S104: If the water pollution area is a densely built-up area, the sewage in the water pollution area is collected by a pre-set end-of-pipe interception method.

[0049] Here, the end-of-pipe interception method involves intercepting the water at its end. After interception, pollutants can be collected and treated in a concentrated manner, which can prevent pollutants in sewage from spreading further in the water and reduce the concentration of pollutants.

[0050] End-of-flow interception methods can be:

[0051] 1. An intercepting well is installed at the end of the drainage pipe to intercept and temporarily store runoff or sewage. The intercepting well is usually equipped with baffles or filters to separate solid pollutants and sediments.

[0052] 2. Add a interceptor sewer line at the end of the existing drainage system to direct wastewater to a wastewater treatment plant for processing. The interceptor sewer line will be connected to the existing drainage system, and its flow rate will be controlled via valves or a pumping station.

[0053] 3. Install rainwater retention ponds at the end of the drainage system to retain and slowly release rainwater, reducing peak flow and settling pollutants. Retention ponds can be surface ponds or underground storage tanks, and their design capacity is determined based on regional rainfall and drainage volume.

[0054] 4. Diversion wells are installed at key nodes of the drainage pipeline to separate initial rainwater and sewage, guiding them to different treatment facilities. The diversion wells are equipped with overflow weirs or diversion plates to control flow rate and direction.

[0055] 5. Install overflow control devices in intercepting or diverting wells to control excess rainwater overflow during heavy rain and prevent the drainage system from being overloaded. Overflow control devices can be overflow weirs, gates, or floating devices, designed according to specific requirements.

[0056] The above-mentioned end-of-pipe interception methods can be used individually or in combination to meet the water quality improvement needs and drainage characteristics of different regions. Figure 7 This is a distribution map of end-of-pipe interception methods in high-density built-up areas, with reference to... Figure 7 In densely built-up areas, the above measures can effectively intercept and treat rainwater and sewage, improve the water quality of rivers and water bodies, and reduce pollution.

[0057] Step S105: If the water pollution area is not a high-density built-up area, obtain the distribution of gate stations in the water pollution area and control the gate stations to close so that the water level of the river in the water pollution area is at a preset low level; the low level is the water level that allows abnormal outlets in the water pollution area to be exposed.

[0058] In one embodiment, reference is made to Figure 2 Before step S105, which involves obtaining the distribution of sluice gates within the water pollution area, the method further includes:

[0059] Step S201: Obtain the historical water resource demand corresponding to the water pollution area.

[0060] Here, historical water resource demand includes water resource demand from industries such as agriculture, fisheries, and manufacturing.

[0061] Step S202: Determine whether the historical water resource demand is greater than the first preset demand.

[0062] Here, the first preset requirement is set in advance based on the actual situation.

[0063] Step S203: If the historical water resource demand is greater than the first preset demand, the water pollution area is identified as an area with high industrial development demand.

[0064] Here, the high-industry development demand areas are those regions with a large number of agricultural, fishery and industrial activities, and a high demand for water resources.

[0065] Step S204: If not, determine whether the historical water resource demand is greater than the second preset demand.

[0066] Step S205: If the historical water resource demand is greater than the second preset demand, the water-polluted area is determined as a medium-sized industrial development demand area; if the historical water resource demand is not greater than the second preset demand, the water-polluted area is determined as a low-sized industrial development demand area; wherein, the first preset demand is greater than the second preset demand.

[0067] Here, the areas with high demand for industrial development are those with a certain number of agricultural, fishery, and industrial activities, which have a high demand for water resources.

[0068] Low industrial development demand areas are those with sparse agricultural, fishing, and industrial activities, and thus low demand for water resources.

[0069] In one embodiment, reference is made to Figure 3 Before step S105, which involves obtaining the distribution of sluice gates within the water pollution area, the method further includes:

[0070] Step S301: Obtain water level data of river channels and external rivers within the water pollution area; wherein, the external rivers are connected to the river channels.

[0071] Here, there is a water exchange relationship between the river water and the outer river water. The river water can flow into the outer river water, and the outer river water can also flow back into the river water.

[0072] Step S302: Based on the river water level data and the external river water level data, determine the relationship between the river water and the external river water in the water pollution area; the relationship between the river water and the external river water includes: the river water level can be controlled by the external river water level, and the river water level cannot be controlled by the external river water level.

[0073] In one embodiment, reference is made to Figure 4 When the water pollution area is an area with low industrial development needs, step S105, which involves obtaining the distribution of gate stations within the water pollution area and controlling the closure of the gate stations, includes:

[0074] Step S401: Determine whether the relationship between the river water and the outer river water is that the river water level can be controlled by the outer river water level.

[0075] Step S402: If yes, obtain the real-time water level information of the outer river and determine whether the real-time water level information of the outer river is lower than the low water level threshold.

[0076] Here, the low water level threshold is the pre-set minimum water level of the river channel.

[0077] Step S403: If the real-time water level of the outer river is lower than the low water level threshold, control each gate station to close according to the distribution of gate stations; if the real-time water level of the outer river is not lower than the low water level threshold, control each gate station to close according to the distribution of gate stations, and at the same time control the drainage of water conservancy hubs in the water pollution area.

[0078] here, Figure 5 This is a map showing the distribution of sluice gates / water conservancy projects within the polder area. Figure 6 This is a map showing the distribution of sluice gates and pumping stations within the water pollution area, with reference to... Figure 5 and Figure 6 Analyzing the construction of sluice gates, if a sluice gate without pumping function is not available, it can be closed when the water level of the outer river is at its lowest, thereby lowering the river water level and treating water pollution areas at low water levels. When a sluice gate is equipped with pressurized pumping and drainage equipment, and the water level of the outer river is not lower than the low water level threshold and the river water level submerges the outlets along the route, pressurized pumping can be used to lower the water level and treat water pollution areas at low water levels.

[0079] If the water level of the river can not be controlled by the water level of the outer river, the sluice gates can be closed and the water conservancy hub can be used for forced drainage to reduce the water level of the river to the lowest level in order to treat the water pollution area at the low water level.

[0080] Specifically, areas with low industrial development needs have lower water resource requirements, and the water level of rivers and canals in water-polluted areas can be reduced by closing all sluice gates in the area.

[0081] In one embodiment, reference is made to Figure 8 When the water pollution area is an area with development needs for medium-sized industries, step S105, which involves obtaining the distribution of gate stations within the water pollution area and controlling the closure of the gate stations, includes:

[0082] Step S801: Divide the water pollution area into multiple first treatment zones according to the distribution of sluice gates; set up a sluice gate at each end of the river in each first treatment zone.

[0083] Here, the demand for water resources in areas with industrial development needs is relatively high. It is necessary to divide the water pollution area into multiple first-level treatment zones and carry out water pollution treatment in each first-level treatment zone separately.

[0084] Step S802: Determine whether the relationship between the river water and the outer river water is that the river water level can be controlled by the outer river water level.

[0085] Step S803: If yes, obtain the real-time water level information of the outer river and determine whether the real-time water level information of the outer river is lower than the low water level threshold.

[0086] Step S804: If the real-time water level of the outer river is lower than the low water level threshold, control each gate station in a first treatment zone to close according to a preset sequence; if the real-time water level of the outer river is not lower than the low water level threshold, control two gate stations in a first treatment zone to close according to a preset sequence, and simultaneously control the drainage of the water conservancy hub in the first treatment zone.

[0087] Here, the preset order is set in advance according to the actual situation. When one first treatment zone is treated, it does not affect the use of water resources in other first treatment zones.

[0088] In one embodiment, reference is made to Figure 9 When the water pollution area is an area with high industrial development needs, step S105, which involves obtaining the distribution of gate stations within the water pollution area and controlling the closure of the gate stations, includes:

[0089] Step S901: Divide the water pollution area into multiple second treatment zones according to the distribution of gate stations; at least two gate stations are set up at one end of the river in each second treatment zone.

[0090] Here, areas with high-tech industry development have a high demand for water resources, necessitating the division of the water-polluted area into multiple secondary treatment zones, with each zone undergoing separate water pollution treatment. The area of ​​each secondary treatment zone is smaller than that of the primary treatment zone.

[0091] Step S902: Determine whether the relationship between the river water and the outer river water is that the river water level can be controlled by the outer river water level.

[0092] Step S903: If yes, obtain the real-time water level information of the outer river and determine whether the real-time water level information of the outer river is lower than the low water level threshold.

[0093] Step S904: If the real-time water level of the outer river is lower than the low water level threshold, control the gate station in the second treatment zone to close in a preset sequence, and at the same time block the abnormal discharge outlet in the second treatment zone according to the preset blocking method.

[0094] Step S905: If the real-time water level information of the outer river is not lower than the low water level threshold, control each gate station in a second treatment zone to close in a preset order, control the drainage of the water conservancy hub in the second treatment zone, and at the same time block the abnormal outlets in the second treatment zone according to the preset blocking method.

[0095] Here, the pre-set sealing method is to use a cofferdam to treat the bottom sediment in the second treatment zone, use airbags or brickwork to seal the abnormal discharge outlets, lower the water level for construction, and realize the construction of the onshore rainwater and sewage pipe network system.

[0096] In one embodiment, reference is made to Figure 10 Before step S106, the method further includes:

[0097] Step S1001: Obtain the real-time river water level and real-time pipeline water level in the water pollution area at preset time intervals, and determine whether the real-time river water level is higher than the preset low water level.

[0098] Here, the preset time interval is set in advance according to the actual situation.

[0099] Step S1002: If the real-time river water level is higher than the preset low water level, the abnormal outlets in the water pollution area are blocked according to the preset blocking method so that the real-time pipeline water level is lower than or equal to the real-time river water level.

[0100] Here, the real-time water levels of rivers and pipes in the water-polluted area are periodically acquired based on preset time intervals to ensure that abnormal discharge outlets can be exposed.

[0101] In one embodiment, reference is made to Figure 11 The preset water pollution thresholds include preset river and canal water pollution thresholds. After step S102, which involves dividing the polder area to be treated into at least one water pollution zone based on water environment data and preset water pollution thresholds, the method further includes:

[0102] Step S1101: Determine whether the river water data below the preset river water pollution threshold is below the preset high pollution threshold.

[0103] Here, the preset high pollution threshold is set in advance based on the actual situation, representing the degree of pollution in the water pollution area.

[0104] Step S1102: If yes, identify the water pollution area as a key black and odorous area.

[0105] Here, the key black and odorous areas are those with severe water pollution, poor water quality, and negative impacts on residents' lives and the ecological environment, requiring priority remediation. Typically, the water in these key black and odorous areas is black and smelly, with low transparency and severely excessive levels of indicators such as BOD.

[0106] Step S1103: If not, determine the water pollution area as a lightly polluted area.

[0107] Here, the lightly polluted area refers to an area where the water quality is slightly polluted, but the degree of pollution is relatively light, and the impact on the ecological environment and residents' lives is relatively small.

[0108] Step S106: Treat the water pollution area at a low water level according to the preset treatment method.

[0109] In one embodiment, the preset treatment method includes an onshore treatment method and a riverbed treatment method. Step S106 includes:

[0110] When the water pollution area is a key black and odorous area, the water pollution area at the preset low water level is treated according to the onshore treatment method and the riverbed treatment method respectively.

[0111] Alternatively, when the water pollution area is a lightly polluted area, the water pollution area at a preset low water level can be treated according to the onshore treatment methods.

[0112] Specifically, onshore governance methods may include:

[0125] The method for riverbed management involves using cofferdams to dredge and treat the sediment at the bottom of the river.

[0126] This invention provides a method for water environment management in water-rich areas. The method includes: acquiring water environment data within a polder area to be managed; dividing the polder area into at least one water-polluted zone based on the water environment data and a preset water pollution threshold; a water-polluted zone is defined as an area where the water environment data exceeds the water pollution threshold; determining whether the water-polluted zone is a high-density built-up area; if the water-polluted zone is a high-density built-up area, collecting wastewater within the water-polluted zone using a pre-set end-of-pipe interception method; if the water-polluted zone is not a high-density built-up area, acquiring the distribution of sluice gates within the water-polluted zone, controlling the sluice gates to close, so that the water level of the river within the water-polluted zone is at a preset low level; the low level is defined as the water level at which abnormal discharge outlets in the water-polluted zone are exposed; and managing the water-polluted zone at the low level according to a preset management method. This method, by dividing the polder area to be managed into multiple different water-polluted zones and managing them separately, can effectively utilize the water resource characteristics of water-rich areas, thereby improving water resource management efficiency and reducing energy consumption for water resource management.
