Description

Technical Field

[0001] The invention relates to the technical field of tidal flow artificial wetlands, and in particular to a landscape water body circulation purification simulation method and system. Background Art

[0002] As a new type of enhanced wetland system, tidal flow artificial wetlands use the pore suction generated by the tidal operation of the saturated wetland surface of the bed to absorb oxygen from the atmosphere into the bed, which significantly improves the oxygen transfer and utilization rate in the wetland bed, thereby enhancing the wetland's purification effect on pollutants. In tidal flow artificial wetlands, the wetland bed needs to be filled with sewage and emptied alternately on a regular basis to improve the utilization rate of the wetland.

[0003] In the prior art, there are three methods for calculating the emptying time of artificial wetlands: the residence time method, the surface load method and the rate coefficient method. Although the residence time method and the surface load method have the characteristics of simply and quickly obtaining the volume and area of ​​the wetland, since the parameters are determined by the designers based on previous experience, the obtained wetland volume data is not accurate enough and is too dependent on the experience of the designers. The rate coefficient method has the characteristics of reasonable design parameters and relatively accurate wetland area, but it has limitations in targeting pollutants.

[0004] Therefore, there is an urgent need for a more accurate and efficient landscape water circulation purification simulation method and system. Summary of the invention

Modifications and deformations of the present invention by other discrete simulation software are also within the scope of the claims of the present invention and the equivalent technology.

[0062] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0063] Figure 1 The process principle of the landscape water circulation purification simulation method according to the embodiment of the present invention is described in detail. Specifically, Figure 1 FIG. 1 is a schematic diagram of the process principle of the landscape water circulation purification simulation method according to an embodiment of the present invention. Figure 1 As shown, the method includes steps S110 to S160.

[0064] S110. Set the initial purification parameters as needed and input the initial operation parameters into the landscape water circulation purification simulation device; wherein the landscape water circulation purification simulation device includes an artificial wetland, an integrated purification device and a pool; the initial operation parameters include the initial data information of the water body, the oxygen content threshold of the water body, the adsorption rate of the integrated purification device and the pollutant content threshold. In other words, the landscape water circulation purification simulation device is used to set the initial parameters and initial operation parameters, i.e., the initial values, and generate water body intelligent bodies according to the initial flow. Each water body intelligent body represents a unit number of water bodies and carries the initialized COD, BOD5, TN, TP, NH4 + -N, turbidity and other pollutant content and DO content.

[0065] In a specific embodiment, Figure 2 and Figure 3 The initial data information setting is generally described, including: Figure 2 It is an operation parameter setting diagram of the landscape water circulation purification simulation device provided by an embodiment of the present invention; Figure 3 This is an interface diagram of the water body operation status and initialization parameter settings of the landscape water body circulation purification simulation device provided by the embodiment of the present invention. Figure 2 As shown in FIG. 1 , the input parameters of the landscape water cycle purification simulation device include water volume, initial index of pollutants, wetland module, integrated device module (i.e., integrated purification device) and pool module. Figure 3 As shown, the state of the water body in the landscape water circulation purification simulation device and the setting of the system initial parameters, such as the total water volume of the system is 11.3 cubic meters and the porosity is 1%; the maximum and minimum values ​​of the concentration of each pollutant in the water body, and the maximum and minimum values ​​of the oxygen content.

[0066] It should be noted that the initial data information of the water body is the initial parameters and initial operating parameters of the landscape water body circulation purification simulation device; among them, the initial parameters include the emptying set time, the first-order reaction rate constant at temperature T, the volume of the artificial wetland, the water volume of the artificial wetland, the water volume of the integrated purification device, the adsorption rate of the integrated purification device, the water volume of the pool, the initial flow rate of the artificial wetland, the initial oxygen content and the initial pollutant content; the initial operating parameters include the total amount of water in the system, the porosity, the maximum and minimum concentrations of each pollutant in the water body, and the maximum and minimum oxygen content.

[0067] Set the initial purification parameters as needed and input the initial operation parameters; wherein the initial parameters include the set emptying time, the first-order reaction rate constant at temperature T, the volume of the artificial wetland, the water volume of the artificial wetland, the water volume of the integrated purification device, the adsorption rate of the integrated purification device, the water volume of the pool, the initial flow rate of the artificial wetland, the initial oxygen content and the initial pollutant content; the initial operation parameters include the total amount of water in the system, the porosity, the maximum and minimum concentrations of each pollutant in the water, and the maximum and minimum oxygen content.

[0068] S120. According to the initial data information of the water body and the initial purification parameters, the water body of unit mass is regarded as a water body intelligent body; wherein the initial data information of the water body includes initial flow, initial oxygen content and initial pollutant content.

[0069] It should be noted that oxygen content refers to dissolved oxygen content, that is, molecular oxygen dissolved in water, recorded as DO. The landscape water circulation purification simulation device has built an artificial wetland module, an integrated purification device module and a pool module, and further built a water body intelligent body.

[0070] Specifically, according to the characteristics of the circulation and purification process of landscape water bodies, a combination of discrete simulation and intelligent agent simulation is adopted to establish intelligent agents of tidal flow artificial wetlands, integrated devices, and pools. Based on the flow direction of landscape water bodies, pollutant treatment logic, etc., the process flow of the purification process is simulated.

[0071] Discrete simulation can capture the dynamics and nonlinearity of an organization, but it ignores the uniqueness of entities and how they interact with each other. The present invention is agent-based modeling, which focuses on the individual active components in the system. Agent-based methods do not have these limitations and focus on the behavior of individuals and their interactions.

[0072] S130, the water body intelligent body enters the artificial wetland for purification, and obtains the water oxygen content of the purified water body intelligent body according to the initial data information of the water body; uses the preset water oxygen content threshold to determine the water oxygen content of the water body intelligent body, and when the water oxygen content is less than the water oxygen content threshold, the artificial wetland is emptied until the emptying set time is reached, and the wetland emptying start time and wetland emptying end time are determined.

[0073] The water body intelligent body enters the wetland module, wherein the wetland is an artificial subsurface flow wetland; the speed at which the water body intelligent body enters the wetland module is controlled according to the actual flow rate entering the wetland module; the molecular oxygen in the water body intelligent body is dissolved in the water body of the artificial wetland and summed with the DO in the wetland water body; the ratio of the average effluent concentration of each pollutant to the average inlet concentration can be calculated through the first-order reaction rate constant at the artificial wetland volume, designed water volume, porosity, and temperature T: a certain proportion of the pollutants in the wetland water body are purified according to the ratio, and the remaining pollutants are evenly distributed in the wetland water body.

[0074] Specifically, the water body intelligent agent enters the artificial wetland for purification, and obtains the oxygen content of the water body after purification according to the initial data information of the water body, including, including steps S131-S132.

[0075] S131. According to the initial data information of the water body and the speed at which the water body intelligent body enters the artificial wetland, the amount of oxygen dissolved in the water body by the wetland is obtained, and the total amount of oxygen in the water body intelligent body is determined; S132. According to the pre-acquired proportion of the water body intelligent body entering the artificial wetland for purification and the total amount of oxygen in the water body intelligent body, the amount of pollutant purification of the intelligent water body is determined. S133. According to the amount of pollutant purification, the amount of dissolved oxygen consumed is obtained, and then the oxygen content of the water body when the water body intelligent body leaves the artificial wetland is determined.

[0076] The method for obtaining the proportion of the water body intelligent body entering the artificial wetland for purification includes: S13211, obtaining the ratio of the average effluent concentration of each pollutant to the average influent concentration according to the artificial wetland volume, design water volume, porosity and first-order reaction rate constant at temperature T through the following formula;

[0077] Among them, K r is the first-order reaction rate constant at temperature T, day -1 ; V is the volume of artificial wetland matrix in natural state, m 3 ; ε is the porosity, %; Q is the designed water volume of the artificial wetland, m 3 / d; SS13212. According to the ratio of the average effluent concentration of each pollutant to the average influent concentration, obtain the proportion of the water body intelligent body entering the artificial wetland for purification.

[0078] Specifically, the method for determining the amount of pollutants purified by the intelligent water body based on the pre-acquired proportion of the intelligent water body entering the artificial wetland for purification and the total amount of oxygen in the intelligent water body includes: S13221, obtaining the amount of wetland pollutants according to the following formula based on the pre-acquired proportion of the intelligent water body entering the artificial wetland for purification and the initial pollutant content of the intelligent water body; wherein, the amount of wetland pollutants = the original amount of wetland pollutants + the amount of pollutants carried by the entering intelligent water body; S13222, dividing the amount of wetland pollutants by the number of intelligent water bodies existing in the wetland at this time to obtain the mean value of pollutants in the intelligent water body; S13223, subtracting the mean value of pollutants in the intelligent water body from the amount of wetland pollutants to obtain the total amount of pollutants in the wetland; S13224, obtaining the amount of pollutants purified by the intelligent water body based on the original amount of pollutants in the wetland and the total amount of pollutants in the wetland.

[0079] Specifically, when the water body intelligent body enters the wetland, the water body is diverted according to the proportion of the water body intelligent body entering the artificial wetland for purification calculated above. This proportion of water bodies enter the purification process, and the pollutants carried by this part of the water body are purified and are not counted in the number of pollutants added to the wetland. The wetland module will determine the amount of pollutants carried by another water body in the unpurified process and add it to the total number of pollutants in the wetland; wetland pollutants = original wetland pollutants + pollutants carried by the entering water body. When the water body leaves the wetland module, the number of all pollutants contained in the wetland at this time will be divided by the number of water body bodies existing in the wetland body at this time (including the purified and unpurified branches), and the average value of water pollutants in the wetland will be obtained. This value will be assigned to the water body leaving the wetland, and this value will be subtracted from the total number of pollutants in the wetland.

[0080] The method for obtaining the amount of dissolved oxygen consumed according to the amount of pollutant purification, and then determining the oxygen content of the water body when the water body intelligent body leaves the artificial wetland, includes: S1331, determining the amount of dissolved oxygen consumed according to the amount of pollutant purification and the amount of oxygen required for unit pollutant purification; S1332, obtaining the dissolved oxygen content of the wetland according to the original dissolved oxygen content of the wetland minus the consumed dissolved oxygen content; S1333, dividing the dissolved oxygen content of the wetland by the number of water body intelligent bodies existing in the wetland at this time, to obtain the average dissolved oxygen content of the water body intelligent body; S1334, subtracting the average dissolved oxygen content of the water body intelligent body from the dissolved oxygen content of the wetland, to obtain the total dissolved oxygen content of the wetland; S1335, obtaining the oxygen content of the intelligent water body according to the original dissolved oxygen content of the wetland and the total dissolved oxygen content of the wetland.

[0081] According to the amount of pollutant purification, the amount of dissolved oxygen consumed can be calculated, and the consumption is subtracted from the total DO value in turn, and the remaining DO value is evenly distributed in the water body of the wetland outlet. Specifically, the DO value required for unit pollutant purification is known, and the consumed DO value is calculated according to the amount of water pollutants in the purification branch. After consumption, the consumption value is subtracted from the overall DO value, and when the water body intelligent body leaves, the average value is assigned to the leaving water body intelligent body, and the DO value carried when leaving is also subtracted from the total DO value of the wetland.

[0082] In short, when the water body intelligent body leaves the wetland module, it determines whether the DO value in the water body is less than the water body oxygen content threshold. If it is, the wetland enters the emptying state, the water body directly leaves the system, and the wetland module stops the water body from entering. After the wetland is emptied for a set time, normal water inflow and outflow are restored, and the DO value of the wetland increases by a certain amount according to the emptying time.

[0083] S140. When the oxygen content of the water body is greater than the oxygen content threshold of the water body, the water body intelligent body enters the integrated purification device for purification; wherein, the pollutant content of the water body intelligent body is obtained according to the preset initial purification parameters and the adsorption rate of the integrated purification device; the pollutant content of the water body intelligent body is determined by using the preset pollutant content threshold, and when the pollutant content of the water body intelligent body exceeds the pollutant content threshold, the integrated purification device adds medicine according to the set dosage and set time, and determines the dosing time.

[0084] Among them, the integrated device can be understood as a device, in which pollutants are adsorbed and purified through operations such as adding drugs. This simulation only considers the changes in the water body in this process, and does not consider the specific operations of the integrated device. When the wetland is not drained, the flow rate of water entering the integrated device is controlled according to the actual pumping speed of the front pump of the integrated device. According to the adsorption rate of the integrated purification device, the purification amount of pollutants is calculated, and the number of purified pollutants is subtracted from the water body intelligent body. When the water body leaves the integrated purification device module, it is determined whether the content of each pollutant in the water body intelligent body exceeds the pollutant content threshold. If it exceeds, the landscape water body circulation purification simulation device of the present invention prompts that dosing is required and displays the expected dosing time point.

[0085] S150: When the pollutant content of the water body intelligent body is less than the pollutant content threshold, the water body intelligent body enters the pool for purification and then circulates into the artificial wetland.

[0086] The method in which the water body intelligent body enters a pool for purification and then circulates into an artificial wetland includes: S151, the water body intelligent body overflows from the integrated purification device into pool 1, overflows from pool 1 into pool 2, and enters pool 3 from pool 2 through a pipe; S152, determining whether the artificial wetland is in an empty state, if the artificial wetland is in an empty state, the water body intelligent body enters the integrated purification device from the pool 3; S153, if the artificial wetland is in a non-emptying state, the water body intelligent body enters the artificial wetland from the pool 3.

[0087] In order to further improve the accuracy of the landscape water circulation purification simulation device of the present invention, the outlet flow rate of the pool 2 is monitored; wherein the outlet flow rate of the pool 2 is realized by the following formula:

[0088]

[0089] Among them, V is the outlet velocity of pool 2, g is the acceleration of gravity, h1 is the water surface height of pool 2; h2 is the water surface height of pool 3.

[0090] S160, the landscape water body circulation purification simulation device obtains visualized water body data, wetland emptying start time and wetland emptying end time, and drug addition time according to the purification process of the landscape water body circulation purification simulation device.

[0091] Landscape water body circulation purification simulation device Landscape water body circulation purification simulation device visualized water body data includes visualized water body operation status, concentration fluctuations of various pollutants and oxygen content in the water body.

[0092] Figure 4 and Figure 5 After the landscape water circulation purification simulation device is running, the data analysis or prediction results obtained are displayed as a whole; Figure 4 It is a display diagram of the water body operation status and the wetland emptying start time and wetland emptying end time of the landscape water body circulation purification simulation device provided by an embodiment of the present invention; the state of the water body in the landscape water body circulation purification simulation device, and the start emptying time and end emptying time of each artificial wetland emptying. Figure 5 This is a diagram showing the concentration fluctuations of various pollutants and oxygen content in the water body of the landscape water body circulation purification simulation device provided by an embodiment of the present invention.

[0093] That is to say, after the operation of the landscape water circulation purification simulation device, the dynamic process of the system is displayed in three-dimensional visualization, and the wetland emptying time and the emptying end time are output, such as Figure 4 Dynamic statistical data, showing the concentration fluctuations of various pollutants and DO in the water body, such as Figure 5 shown.

[0094] In summary, the landscape water circulation purification simulation method of the present invention comprehensively considers the fluctuation of pollutants in the water body, the water pollutants entering from different branches, and combines the adsorption purification logic of the wetland and the integrated purification device to dynamically simulate the purification process of the water body in the circulation purification system. It can comprehensively consider various dynamic influencing factors, and the results are closer to the actual situation, which has important reference significance for the prediction of wetland emptying time and integrated device dosing time. Compared with traditional methods, the present invention is easy for technicians to operate. People who do not have modeling technology can quickly obtain simulation results by modifying key parameter conditions such as initial water pollutant concentration, wetland porosity, etc., without re-modeling, and the simulation results have a smaller fluctuation range and are more accurate.

[0095] Corresponding to the above-mentioned landscape water body circulation purification simulation method, the present invention also provides a landscape water body circulation purification simulation device. Figure 6 The functional modules of the landscape water circulation purification simulation system according to an embodiment of the present invention are shown.

[0096] like Figure 6 As shown, the landscape water circulation purification simulation system 600 provided by the present invention can be installed in an electronic device. According to the functions to be implemented, the landscape water circulation purification simulation system 600 can include an intelligent body building unit 610, a wetland purification unit 620, an integrated purification device purification unit 630, a pool unit 640 and a visualization unit 650.
