[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] See also Figure 1 As shown, the present invention provides a method for optimizing, analyzing and processing water supply and drainage systems of green ecological buildings, the method comprising: step one, rainwater monitoring of the water supply and drainage system: monitoring rainwater information of the water supply and drainage system in the rainwater pool, the rainwater information of the rainwater including physical information, chemical information, biological information and rainwater volume, the physical information including turbidity and color chromaticity value, the chemical information including pH, chemical oxygen demand and heavy metal content, the biological information including total bacteria count and coliform count.
[0025] It should be added that the turbidity is obtained by monitoring through an in-situ turbidity sensor installed in the rainwater tank. The in-situ turbidity sensor is usually composed of a light source, a detector and a signal processing unit. The in-situ turbidity sensor is installed at an appropriate position in the rainwater tank, such as near the outlet or in the middle of the tank, to monitor the turbidity of rainwater in real time. The light emitted by the light source is irradiated into the water, the detector receives scattered or transmitted light, and the signal processing unit converts the optical signal into an electrical signal and calculates the turbidity based on a pre-calibrated relationship.
[0026] It should be added that the color chromaticity value is obtained by placing a camera above the rainwater pool. The camera transmits the captured image to the image processing system. The image processing system pre-processes the image, including denoising, contrast enhancement and other operations, in order to better extract color information, and then uses a color recognition algorithm to analyze the color in the image and convert the color into a numerically represented color chromaticity value.
[0027] It should be added that the pH is monitored by a pH sensor placed in the rainwater tank.
[0028] It should be added that the chemical oxygen demand is obtained by installing a UV absorption sensor in a rainwater pool. The optical path system of the sensor emits ultraviolet light and receives light signals after passing through rainwater. The light signals are then converted into electrical signals and transmitted to the data processing system. The data processing system calculates the chemical oxygen demand of the rainwater based on pre-set algorithms and calibration data.
[0029] It should be added that the method of obtaining the heavy metal content is: install a heavy metal ion selective electrode in the rainwater pool so that it is in full contact with the rainwater, connect the electrode to a potentiometer, and the potentiometer measures the potential value of the electrode in real time. The potential value is converted into the concentration of heavy metal ions according to the Nernst equation, and then the heavy metal content is obtained.
[0030] It should be added that the total bacterial count is obtained by fixing a biorecognition element containing a specific fluorescent marker on the surface of the optical biosensor. When the bacteria in the rainwater combine with the biorecognition element, a fluorescent signal will be generated under excitation light of a specific wavelength. The optical detection system of the optical biosensor detects the fluorescent signal and converts it into an electrical signal, thereby calculating the total bacterial count.
[0031] It should be added that the number of coliform bacteria is obtained by fixing specific antibodies on the surface of the sensor. When the coliform bacteria in the rainwater bind to the antibodies, it will cause changes in the physical or chemical properties of the sensor, such as resistance, capacitance, optical properties, etc., and then by detecting these changes, the presence and number of coliform bacteria can be determined.
[0032] Step 2: Confirm the use of rainwater: According to the rainwater information of the water supply and drainage system in the rainwater pool, confirm the use of rainwater in the rainwater pool.
[0033] It should be added that the uses of rainwater in rainwater ponds include but are not limited to: landscape irrigation, non-drinking water inside buildings, vehicle washing and industrial use.
[0034] See also Figure 2 As shown, for example, the method of confirming the use of rainwater in the rainwater pool includes: Q1, confirming the physical qualification index of rainwater in each rainwater use path according to the physical information of rainwater in the rainwater pool of the water supply and drainage system i is the number of rainwater use channels, i=1,2,......,m.
[0035] Furthermore, the confirmation of the physical qualification index of rainwater in each rainwater use path includes: Q1-1, matching and comparing the turbidity of rainwater in the rainwater pool of the water supply and drainage system with the turbidity interval of each turbidity qualification index corresponding to each rainwater use path, and then obtaining the turbidity qualification index of rainwater in each rainwater use path, and recording it as β i .
[0036] Q1-2, according to β i The color chromaticity value qualification index of rainwater in each rainwater use channel is obtained by the same analysis method and recorded as β i ′.
[0037] In a specific embodiment, if the rainwater is used for landscape irrigation, the high turbidity qualified index for landscape irrigation is 0.9: the rainwater is colorless and transparent or very light yellow, and almost no color changes caused by other impurities can be seen. The medium turbidity qualified index for landscape irrigation is 0.7: the rainwater is light yellow to light yellow, with slight visible impurities, but the overall color is relatively uniform, without obvious turbidity or other abnormal colors (such as brown, gray, etc.). The low turbidity qualified index for landscape irrigation is 0.5: the rainwater color is obviously yellow or other abnormal colors appear (such as brown may indicate that it contains a large amount of organic matter or iron ions, gray may mean that there are more suspended matter, etc.), and there is even turbidity.
[0038] If the color of rainwater is close to colorless or very light yellow, the qualified index of rainwater color for landscape irrigation is 0.9. If the color of rainwater is in the range of light yellow to light yellow, the qualified index of rainwater color for landscape irrigation is 0.7. If the color of rainwater is obviously yellowish, the qualified index of rainwater color for landscape irrigation is 0.5.
[0039] Q1-3. Statistical calculation of the physical qualification index of rainwater in various rainwater use channels
[0040] Q2. According to the chemical information of rainwater in the rainwater pool of the water supply and drainage system, confirm the chemical qualification index of rainwater in various rainwater use channels
[0041] Furthermore, the determination of the chemical qualification index of rainwater in each rainwater use path includes: Q2-1, according to the pH value of rainwater in the rainwater pool of the water supply and drainage system, calculating the pH qualification index γ of rainwater in each rainwater use path i .
[0042] Furthermore, the pH qualification index of rainwater in each rainwater use path includes: Q2-1-1, subtracting the pH of rainwater in the rainwater pool of the water supply and drainage system from the set reference standard pH to obtain the pH difference of rainwater in the rainwater pool of the water supply and drainage system.
[0043] Q2-1-2. If the pH difference of rainwater in the rainwater pool of the water supply and drainage system is within the permitted pH difference range of a certain rainwater use route, the pH qualification index of the rainwater in this rainwater use route shall be recorded as 1.
[0044] Q2-1-3. If the pH difference of rainwater in the rainwater pool of the water supply and drainage system is less than the lower limit of the permissible pH difference range for a certain rainwater use route, the ratio of the pH difference of rainwater in the rainwater pool of the water supply and drainage system to the lower limit of the permissible pH difference range for a certain rainwater use route shall be used as the pH qualification index of rainwater in the rainwater use route, denoted as ν1.
[0045] Q2-1-4. If the pH difference of rainwater in the rainwater pool of the water supply and drainage system is greater than the upper limit of the pH difference permissible range of a certain rainwater use route, the ratio of the upper limit of the pH difference permissible range of a certain rainwater use route and the pH difference of rainwater in the rainwater pool of the water supply and drainage system is used as the pH qualification index of rainwater in the rainwater use route, recorded as ν2, and the pH qualification index of rainwater in each rainwater use route is obtained, recorded as γ i , γ i The value is 1 or ν1 or ν2.
[0046] Q2-2, according to γ i The chemical oxygen demand and heavy metal content qualification index of rainwater in each rainwater use pathway are obtained by the same analysis method, and are recorded as γ i ′ and γ i ″.
[0047] Q2-3. Statistical analysis of the chemical compliance index of rainwater in various rainwater use channels γ0, γ0′ and γ0″ are the reference pH qualified index, chemical oxygen demand qualified index and heavy metal content qualified index respectively, and e is a natural constant.
[0048] It should be added that γ0, γ0′ and γ0″ are all extracted from the technical specification table for water supply and drainage system optimization.
[0049] Q3. According to the biological information of rainwater in the rainwater pool of the water supply and drainage system, confirm the biological qualification index of rainwater in various rainwater use channels
[0050] Furthermore, the biological qualification index of rainwater in various rainwater use channels is confirmed, including: Q3-1, the total bacteria count and coliform count of rainwater in the rainwater pool are recorded as D0 and D1 respectively.
[0051] Q3-2. Statistical analysis of biological compliance index of rainwater in various rainwater use channels D i ′ and D i ″ are the permitted total bacteria count and permitted coliform count for the i-th rainwater use pathway.
[0052] It should be added that Di ′ and D i ″ are extracted from the technical specification table of water supply and drainage system optimization.
[0053] Q4. Import the physical qualification index, chemical qualification index and biological qualification index of rainwater in various rainwater use channels into the rainwater qualification index analysis model to obtain the rainwater qualification index of rainwater in various rainwater use channels, which is recorded as δ i .
[0054] It should be added that the specific analysis formula of the rainwater qualification index analysis model is: the rainwater qualification index δ of rainwater in each rainwater use channel i , w1, w2 and w3 are the weights of the set physical qualification index, chemical qualification index and biological qualification index respectively.
[0055] w1+w2+w3=1, w1>w2>w3.
[0056] It should be added that the physical properties of rainwater, such as turbidity and color, are most easily perceived by users. If the physical properties are not up to standard, for example, when water with too high turbidity is used for car washing, users can directly see stains on the car paint, or when used for landscape irrigation, obvious turbidity will affect the aesthetics of the landscape. At the same time, too much suspended solids may cause pipe blockage, especially in non-drinking water systems inside buildings (such as toilet flushing systems). Physical impurities may damage equipment such as valves and pipes, directly affecting the safe operation of the water supply and drainage system. The chemical properties of rainwater, such as acidity (pH value), chemical oxygen demand (COD) and heavy metal content, are crucial to the long-term safety of rainwater use. For example, if the acidity is too strong (pH value is too low), the water quality will be affected. ) may corrode pipes and equipment inside buildings. Even if the physical properties are qualified, long-term use will bring safety hazards. However, its impact on the properties of rainwater is less intuitive than that of physics, so the weight of the physical qualification index is greater than that of the chemical qualification index. The biological qualification index of rainwater mainly involves microbial indicators such as total bacteria count and coliform count. This is mainly considered from the perspective of health and safety, especially for non-drinking water uses inside buildings (such as flushing toilets) and landscape irrigation that may come into contact with the human body. However, its long-term safety hazard to the use of rainwater is less than the chemical properties of rainwater. Therefore, w1>w2>w3 is set. For the convenience of analysis, w1 can be specifically taken as 0.5, w2 can be specifically taken as 0.3, and w3 can be specifically taken as 0.2.
[0057] The embodiment of the present invention imports the rainwater qualification index according to the physical qualification index, chemical qualification index and biological qualification index of rainwater in each rainwater use path, confirms the rainwater qualification index of rainwater in each rainwater use path, improves the targeted use of rainwater, thereby ensuring the safety of rainwater use, and at the same time improves the overall efficiency of the water supply and drainage system, thereby improving the stability of the water supply and drainage system.
[0058] Q5. Filter out the maximum value from the rainwater qualification index of each rainwater use path, and use the rainwater use path to which the maximum value belongs as the rainwater use path in the rainwater pool.
[0059] The embodiment of the present invention confirms the use of rainwater in the rainwater pool according to the rainwater information of the water supply and drainage system in the rainwater pool, thereby avoiding the current problem of insufficient attention to rainwater energy-saving analysis, ensuring the refined allocation of rainwater resources, thereby improving the utilization efficiency of rainwater and the utilization rate of rainwater resources.
[0060] Step 3: Extract weather forecast information: Extract weather forecast information, which includes the number of days between the expected next rainy day.
[0061] Step 4: Confirmation of rainwater usage allocation: Based on the weather information from the weather forecast and the historical usage information of the water supply and drainage system, the rainwater allocation information of the water supply and drainage system is confirmed.
[0062] Exemplarily, the confirming of rainwater distribution information of the water supply and drainage system includes: according to the rainwater use path of the water supply and drainage system, extracting the daily rainwater demand of the rainwater use path from the historical use information of the water supply and drainage system, recorded as θ1.
[0063] The number of days until the next rainy day is expected to be recorded as T.
[0064] The total rainwater demand θ2 of this rainwater use route is calculated, where θ2 = θ1*T.
[0065] The drainage volume entering the rainwater tank in each historical drainage cycle is extracted from the historical usage information of the water supply and drainage system, and the average drainage volume is calculated and recorded as θ3.
[0066] The amount of rainwater is recorded as θ4, and then the total rainwater supply of the rainwater tank is calculated as θ5, θ5 = θ4 + θ3*T.
[0067] If θ2≥θ5, tap water with θ2-θ5 added will be used for this rainwater usage path as rainwater allocation information of the water supply and drainage system.
[0068] If θ2<θ5, the qualified rainwater in each rainwater use path will be sorted from large to small, and the second ranked rainwater use path will be extracted. Then the rainwater amount of θ2 will be used for the first ranked rainwater use path and the remaining rainwater amount of θ5-θ2 will be used for the second ranked rainwater use path as the rainwater distribution information of the water supply and drainage system.
[0069] Step 5. Drainage monitoring of the water supply and drainage system: monitor the drainage information of the drainage in each drainage pool. The drainage information includes physical information, chemical information and biological information. The physical information includes drainage turbidity and color chromaticity value, the chemical information includes pH, drainage oxygen demand and heavy metal content, and the biological information includes total bacteria and coliform count.
[0070] It should be added that the method of obtaining drainage information is similar to the method of obtaining rainwater information described above, and will not be repeated here.
[0071] The embodiment of the present invention improves the weather adaptability of the water supply and drainage system by extracting the historical usage information of the water supply and drainage system from the water supply and drainage system based on the weather information of the weather forecast, and then confirming the rainwater distribution information of the water supply and drainage system, thereby planning the storage and use of rainwater in advance, and thus improving the accuracy of the use of rainwater resources, thereby achieving green ecological optimization.
[0072] Step 6. Drainage analysis of the water supply and drainage system: Analyze the circulation permission index of the drainage in each drainage pool based on the drainage execution information of the drainage in each drainage pool.
[0073] See also Figure 3 As shown, exemplarily, the analysis of the circulation permissible index of the drainage in each drainage pool includes: Z1, according to the turbidity and color chromaticity value of the drainage in each drainage pool, calculating the physical qualification index of the drainage in each drainage pool j is the drainage pool number, j=1,2,......,m.
[0074] Furthermore, the physical qualification index of the drainage in each drainage pool is calculated, including: Z1-1, the turbidity of the drainage in each drainage pool is recorded as α j .
[0075] Z1-2. Calculate the qualified turbidity index of the drainage in each drainage pool α′ is the permissible turbidity of the drainage corresponding to the reference drainage that can be recycled.
[0076] It should be added that α′ is extracted from the technical specification table for water supply and drainage system optimization.
[0077] Z1-3, according to The statistical method is similar to the statistical method to obtain the color chromaticity value qualified index of the drainage in each drainage pool, and it is recorded as
[0078] Z1-4. Calculate the physical qualification index of drainage in each drainage pool ψ j , r1 and r2 are the weights of the set drainage turbidity qualification index and color chromaticity value qualification index respectively, r1+r2=1, r1>r2.
[0079] In a specific embodiment, the reference drainage permissible turbidity is 20NTU, the reference drainage permissible quasi-color chromaticity value is 10, the drainage turbidity of the drainage in drainage pool A is 10NTU, and the color chromaticity value of the drainage in drainage pool A is 4.
[0080] Turbidity compliance index of drainage water in drainage pool A The color chromaticity value qualification index of the drainage water in the drainage pool A Then the physical qualification index of drainage in drainage pool A is ψ1=0.5*0.6+0.6*0.4=0.54.
[0081] It should be added that from the perspective of rainwater reuse, high turbidity drainage will limit the various uses of rainwater. If used for landscape irrigation, turbid water may form a mud layer on the soil surface, hindering the breathing of plant roots. If used for car washing, it will leave stains on the car body. If used for flushing toilets, it may cause pipe blockage to increase. In contrast, although the color of drainage will also have a certain impact on the user's acceptance, as long as there are no harmful substances associated with it, in some cases, slightly darker drainage may still meet some uses that do not require high water quality appearance after simple treatment (such as activated carbon adsorption color). Therefore, r1>r2 is set. For the convenience of analysis, r1 can be specifically taken as 0.6 and r2 can be specifically taken as 0.4.
[0082] Z2. Confirm the chemical qualification index of the drainage in each drainage pool according to the pH, chemical oxygen demand and heavy metal content of the drainage in each drainage pool
[0083] It should be added that the confirmation process of the chemical qualification index of the drainage in each drainage pool is as follows: the pH value of the drainage in each drainage pool is recorded as
[0084] Calculate the pH index of the drainage in each drainage pool ω j , To set the reference permissible pH of drainage.
[0085] It should be added that It is extracted from the technical specification table for water supply and drainage system optimization.
[0086] According to ω jThe qualified index of chemical oxygen demand and heavy metal content in each drainage pool is obtained by the same statistical method, and is recorded as ω j ′ and ω j ″.
[0087] Count the chemical compliance index of the drainage in each drainage pool
[0088] Z3. According to the total number of bacteria and coliform count in each drainage pool, confirm the biological qualification index of the drainage in each drainage pool
[0089] It should be added that the confirmation process of the biological qualification index of the drainage in each drainage pool is as follows: the total number of bacteria in the drainage in each drainage pool is recorded as y j .
[0090] Statistical evaluation of the total number of bacteria in each drainage pool to determine the qualified index ρ j , y′ is the total permissible bacterial count in the reference drainage.
[0091] It should be added that y′ is extracted from the technical specification table for water supply and drainage system optimization.
[0092] According to ρ j The statistical method is similar to that of the conventional method to obtain the qualified index of the number of coliform bacteria in the drainage pool, and it is recorded as ρ j ′.
[0093] From j and ρ j ′, the minimum value is selected as the chemical qualification index of the drainage in each drainage pool, recorded as
[0094] Z4. Select the minimum value from the physical qualification index, chemical qualification index and biological qualification index of the drainage in each drainage pool as the circulation permission index of the drainage in each drainage pool.
[0095] Step 7. Confirmation of drainage of water supply and drainage system: Confirm the drainage execution information of each drainage pool according to the circulation permission index of the drainage in each drainage pool.
[0096] Exemplarily, the confirming the drainage execution information of the drainage in each drainage pool includes: comparing the circulation permission index of the drainage in each drainage pool with the set drainage pool circulation permission index.
[0097] If the circulation permission index of drainage in a drainage pool is greater than or equal to the set drainage pool circulation permission index, the circulation pipeline will be selected as the execution information of drainage in the drainage pool.
[0098] If the circulation permission index of drainage in a drainage pool is less than the set drainage pool circulation permission index, the sewage pipe will be selected as the execution information of drainage in the drainage pool, so as to obtain the execution information of drainage in each drainage pool.
[0099] Step 8. Drainage execution of the water supply and drainage system: perform corresponding execution according to the rainwater distribution information of the water supply and drainage system and the drainage execution information of the drainage in each drainage pool.
[0100] The embodiments of the present invention break the current problem of insufficient attention to the drainage part and the comprehensive utilization of rainwater by monitoring and analyzing the rainwater and drainage of the water supply and drainage system, improve the coverage dimension of the water supply and drainage system, and improve the comprehensiveness of the analysis of the circulation characteristics of the water supply and drainage system, thereby improving the balance of water volume, and then realizing the effective utilization of water resources, while reducing the operating cost of the water supply and drainage system.
