Description

Technical Field

[0001] The present invention relates to the technical field of water supply, and in particular to a water supply control method and a water supply system. Background Art

[0002] At present, with the shortage of water resources and the increasing frequency of pollution, the problem of water source pollution has received more and more attention. There are many factors that cause water source pollution, and natural disasters are one of the more important reasons. With the changeable climate, water sources are polluted by heavy rainfall and other factors, resulting in the phenomenon that the water flow input into the water supply system is carrying mud and other debris.

[0003] However, since the existing water supply system usually adopts a conventional water supply treatment method, it is only applicable to the situation where the water quality of the water source is relatively good, and it is unable to perform matching treatment processes according to the different degrees of water quality of the water source. As mentioned above, when the water source is polluted, the water supply system still uses conventional treatment methods to treat the input water, and when the user's water consumption surges during peak hours, the water supply system needs to provide a greater water supply pressure, and the high turbidity of the water will increase the friction resistance of the equipment, which often leads to serious load phenomenon in the water supply system, easily leading to equipment failure and reducing the service life of the equipment, and it is impossible to guarantee the output of water with stable water quality to supply people, affecting people's daily life and health. Summary of the invention

[0004] In order to solve the above problems, the present application provides a water supply control method and a water supply system.

[0005] In the first aspect, the above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0006] A water supply control method comprises the following steps:

[0007] Determine the raw water delivery method according to the turbidity value of the raw water delivered by the water inlet pipe and the current user-side load demand; wherein the delivery method includes sequential delivery, parallel delivery and alternating delivery;

[0008] When the delivery mode is sequential delivery, the one-way valve to be opened is determined to be the first preset one-way valve; wherein, after the first preset one-way valve is opened, the raw water delivered by the water inlet pipe can be delivered to the softening device after passing through the two water storage devices in sequence;

[0009] When the delivery mode is parallel delivery, the one-way valve to be opened is determined to be the second preset one-way valve; wherein, after the second preset one-way valve is opened, the raw water delivered by the water inlet pipe can be delivered to the softening device after passing through the two water storage devices arranged in parallel;

[0010] When the delivery mode is alternate delivery, the one-way valve to be opened is determined to be the third preset one-way valve; wherein, after the first preset one-way valve is opened, the raw water delivered by the water inlet pipe can be alternately input into the two water storage devices respectively, and alternately output to the softening equipment through the two water storage devices;

[0011] Determining the opening operation strategy corresponding to the one-way valve to be opened based on the raw water delivery method;

[0012] The water from the softening equipment is controlled to pass through the oxidation filtration equipment and the disinfection equipment PH in sequence, and the water quality test results output by the disinfection equipment are obtained. After the water quality test results meet the use standards, the water that meets the use standards is supplied to users or stored.

[0013] By adopting the above technical scheme, the transportation method of raw water is determined by the turbidity value of the raw water transported by the water inlet pipe and the current user-side load demand, so that it can be guaranteed that the best transportation state is dynamically adjusted according to the turbidity value of the raw water and the current user-side load demand, and it can be guaranteed that while meeting actual needs, excessive damage to equipment can be reduced and serious impact on people's daily life and health can be avoided. By adaptively executing different transportation methods for raw water and adaptively controlling the opening of the one-way valve, adaptive flow rates and flows are input and output to ensure stable entry into the water storage device and stabilization of the water storage device, avoiding the impact and fluctuation of water quality during transportation, thereby achieving intelligent control effects, improving filtering effects, and extending service life. At the same time, it can also ensure the stability of the output water quality, thereby improving the sedimentation and filtration effects of raw water, thereby transporting stable, low-turbidity raw water to subsequent processes, and improving the water treatment efficiency of the water supply system.

DETAILED DESCRIPTION

[0055] The present application is further described in detail below in conjunction with the accompanying drawings.

[0056] See also Figure 1-10 As shown, in one embodiment, the present application discloses a water supply control method, which specifically includes the following steps:

[0057] S10: Determine the raw water delivery method according to the turbidity value of the raw water delivered by the water inlet pipe 1 and the current user-side load demand; wherein the delivery method includes sequential delivery, parallel delivery and alternating delivery;

[0058] It should be noted that high turbidity water will increase the burden on water treatment equipment in the water supply system, such as water storage device 3, softening equipment and oxidation filtration equipment. In the case of long-term high turbidity water, the efficiency of these equipment will often be reduced, and the water purification effect will be affected, thereby affecting the water quality safety of the water supply system. At the same time, suspended matter in the water will accelerate the wear of equipment such as pipes and pumps, increase maintenance and replacement costs, especially when users have a large water consumption, the wear of equipment will be more significant. When users have a large water consumption, it will affect the stability of the water supply pressure of the water supply system, especially when users have a surge in water consumption during peak hours. The water supply system needs to provide a higher water supply pressure, and when the water quality turbidity is relatively high, the pressure will be too high. When the turbidity level is high, it will often increase the friction resistance of the water supply pipeline and damage the water treatment equipment, which will not only affect the stability of the water supply pressure, but also fail to ensure the output of water with stable water quality to people, affecting people's daily life and health, and easily lead to equipment failure and reduce the service life of the equipment. In this solution, the turbidity value of the raw water transported by the water inlet pipe 1 and the current user-side load demand determine the delivery method of the raw water, which can ensure that the turbidity value of the raw water and the current user-side load demand are dynamically adjusted to the best delivery state, ensuring that it can reduce excessive damage to the equipment and avoid seriously affecting people's daily life and health while meeting actual needs.

[0059] In a preferred example, the present application can be further configured as follows: determining the raw water delivery method according to the turbidity value of the raw water delivered by the water inlet pipe 1 and the current user-side load demand, including:

[0060] S101: collecting the turbidity value of the raw water transported by the water inlet pipe 1 to obtain the turbidity value of the raw water, and determining whether the turbidity value of the raw water is greater than a first preset standard to obtain a first determination result;

[0061] In this embodiment, by collecting the turbidity value of the raw water transported by the water inlet pipe 1, and by comparing the collected turbidity value of the raw water with the first preset standard, the current water quality of the raw water can be quickly and accurately known, so as to dynamically match the corresponding pretreatment scheme according to the current water quality of the raw water, thereby achieving precise control of the raw water treatment process, improving the water treatment efficiency of the water supply system and realizing intelligent and precise water supply control effects.

[0062] It should be noted that turbidity value is one of the important indicators for evaluating the cleanliness of water. The turbidity value can be used to preliminarily understand the concentration of suspended particles in the water, which helps to evaluate the cleanliness and transparency of the water quality, and also helps to prevent damage to the water inlet pipe and water treatment equipment, reduce maintenance costs, and extend the service life of equipment.

[0063] S102: predicting the water consumption of the current user side based on the water consumption prediction model to obtain the load demand of the current user side, and determining whether the load demand of the current user side is greater than a second preset standard to obtain a second determination result;

[0064] It should be noted that when the user-side load demand fluctuates greatly, the water supply system needs to constantly adjust the water supply pressure to meet user needs, which may cause fluctuations in water supply pressure and affect the stability and operating efficiency of the water supply system. In addition, the increase in user-side load demand will lead to an increase in the flow rate in the water supply system network. When it exceeds the design carrying capacity of the pipeline, it will cause problems such as reduced network pressure and pipeline rupture, affecting the normal operation of the water supply system. At the same time, high load demand will cause the load on equipment such as pump stations and water tanks in the water supply system to increase. Long-term high-load operation may cause equipment overload and increased wear, reduce equipment life, and increase maintenance costs. When the user-side load demand fluctuates greatly, high user-side load demand will lead to an increase in the operating cost of the water supply system, including energy consumption, maintenance costs, etc. Therefore, reasonable prediction, management and regulation of current user-side load demand are of great significance to the normal operation of the water supply system, water quality assurance and equipment maintenance, so as to adjust the capacity and pipeline layout of the water supply system according to the actual changes in user-side load demand to adapt to changes in user demand, which will help improve the stability, efficiency and service level of the water supply system, ensure water pressure stability and water quality stability, stabilize pipeline flow, avoid equipment load and reduce the operating cost of the water supply system.

[0065] The water consumption of the current user is predicted based on the water consumption prediction model, which specifically includes the following steps:

[0066] S1021: Collect historical water consumption data, user information, weather data and other related information to form a data set;

[0067] It should be noted that historical water consumption data, user information and weather data are the basis for establishing a water volume prediction model. By analyzing these data, a water volume prediction model can be established to predict future water consumption. By analyzing historical water consumption data and user information, users' water use habits and needs can be understood, which helps to optimize the operation and management of the water supply system. Combined with weather data, the water supply system operation mode can be adjusted according to meteorological conditions, energy costs can be saved, and energy utilization efficiency can be improved. By analyzing user information, user needs can be better understood, more personalized water services can be provided to users, and user experience can be improved. Weather data can also be used for disaster warnings. In cases such as heavy rains and floods, measures can be taken in advance to ensure the normal operation of the water supply system.

[0068] Among them, historical water consumption data, user information, and weather data can be obtained through water supply system records, user files, and weather data released by the Meteorological Bureau and other institutions. For example, historical water consumption data can be obtained from water supply system records, including daily water consumption, time period water consumption, etc. User information can be obtained from user files, such as user type, water use habits, water consumption statistics, etc. Relevant weather data, such as temperature, humidity, precipitation, etc., can be obtained from the Meteorological Bureau and other institutions.

[0069] S1022: Perform one or more preprocessing operations such as cleaning, missing value filling, and feature engineering on the collected data.

[0070] It should be noted that data cleaning can eliminate inaccurate, incomplete or invalid information in the data, improve the quality and reliability of the data, and help reduce errors in data analysis, ensuring that the analysis results are more accurate and reliable. High-quality data can improve the accuracy of modeling and the performance of the model, helping to obtain more accurate prediction results.

[0071] This includes checking whether there are duplicate records in the data set. If there are duplicate values, they need to be deleted to ensure the uniqueness and accuracy of the data; detecting and processing abnormal data, such as judging abnormal values ​​through statistical methods or domain knowledge, and processing them according to the actual situation, such as deleting abnormal values ​​or making corrections; identifying missing values ​​in the data, analyzing the reasons for missing values, and choosing to delete missing values, interpolate and fill them, or use other methods to process them; at the same time, methods such as smoothing or filtering can be used to reduce the impact of noise on data analysis. Noise data refers to random interference in the data.

[0072] S1023: Select appropriate features from the historical data, such as one or more of date, time, user type, and weather conditions as input features of the model.

[0073] S1024: Training historical data based on machine learning models. Specifically, the data set after preprocessing and feature selection is split into a training set and a test set for model training and evaluation of model performance, and the linear regression model is trained using the training set data to fit the linear relationship between the features and the target variable; the formula is:

[0074] y=β 0 +β 1 x 1 +β 2 x 2 +β 3 x 3 …β n x n +∈;

[0075] y represents the predicted water consumption on the current user side (the load demand on the current user side);

[0076] β 0 represents the intercept term of the model;

[0077] (β 1 , β 2 , β 3 , β n ) represents the coefficient of the corresponding feature of the model;

[0078] (x 1 , x 2 , x 3 , x n ) represents the input features of the model, such as date and time features, user type, weather conditions, etc.;

[0079] ∈ represents the error term, that is, the prediction error of the model.

[0080] S1025: Use some historical data to verify and adjust the model and evaluate the prediction performance of the model.

[0081] S1026: Use the trained model to predict the water consumption on the current user side to obtain the current user side load demand.

[0082] S103: Determine a method for conveying the raw water according to the first judgment result and the second judgment result.

[0083] It should be noted that, based on the first judgment result and the second judgment result, the turbidity value of the raw water and whether the current user-side load demand is greater than the preset standard can be quickly obtained to determine the matching transportation method, thereby ensuring the best transportation method and treatment method for the raw water, thereby realizing scientific and refined dynamic adjustment.

[0084] S1031: When at least one of the first judgment result and the second judgment result is greater than, determining that the raw water is transported in parallel or in sequence;

[0085] In the technical solution provided in the above embodiment, when there is at least one judgment result that is greater than, it proves that there is a phenomenon that exceeds the preset standard. In this case, it is necessary to perform parallel or sequential transportation of the raw water, so that the transportation route and water volume of the raw water entering the treatment can be adaptively adjusted, thereby ensuring that the water supply system is not overloaded, extending the service life, and ensuring the stability of the water quality, thereby avoiding affecting the water supply system and users.

[0086] S1031-1: Determine the turbidity value of the raw water and the priority of the current user-side load demand according to the first judgment result and the second judgment result;

[0087] It should be noted that the priority represents the object that the water supply system needs to satisfy first. For example, when the first judgment result is greater than and the second judgment result is less than, the priority of the turbidity value of the raw water is higher than the priority of the current user-side load demand. At this time, in order to avoid affecting the water supply system and users, it is necessary to implement a transportation method that matches the turbidity value of the raw water, that is, to transport in sequence, so as to transport the raw water to the two water storage devices 3 in sequence for sedimentation and filtration, so as to avoid affecting subsequent equipment.

[0088] S1031-2: When the turbidity value of the raw water is consistent with the priority of the current user-side load demand, respectively obtain the turbidity value of the raw water and the score value of the current user-side load demand, and determine the priority corresponding to the high score value as the first priority; wherein, when the turbidity value of the raw water is the first priority, determine the delivery mode of the raw water to be sequential delivery; when the current user-side load demand is the first priority, determine the delivery mode of the raw water to be parallel delivery;

[0089] It should be noted that when the priorities are consistent, it means that the first judgment result and the second judgment result are greater. In order to avoid operational confusion in the water supply system, the turbidity value of the raw water with consistent priorities and the current user-side load demand are used to calculate the scoring value to determine the first priority, and control the water supply system to execute the delivery method matching the first priority, thereby further improving the refined control effect of the water supply system.

[0090] Among them, the first score value corresponding to the turbidity value of the raw water is calculated according to the turbidity value of the raw water and the corresponding weight value, and the second score value corresponding to the current user side load demand is calculated according to the current user side load demand and the corresponding weight value. The first score value and the second score value are compared, and the object with a higher score value is taken as the first priority object, thereby achieving a refined control effect on the water supply system.

[0091] It should be noted that after determining the first priority, the difference between the first score value and the second score value is calculated in real time. When the absolute value of the difference is less than the third preset value, the first priority is not re-determined until the absolute value of the difference is greater than or equal to the third preset value, and the next determination after each determination is determined based on the comparison result of the absolute value of the difference and the third preset value. Avoid frequent changes, which will cause frequent start and stop of equipment, affect the service life of equipment and the stability of water supply, etc.

[0092] S1031-3: When the turbidity value of the raw water and the priority of the current user-side load demand are inconsistent, determine the first priority and the second priority from high to low respectively; wherein, when the turbidity value of the raw water is the first priority, determine that the delivery method of the raw water is sequential delivery; when the current user-side load demand is the first priority, determine that the delivery method of the raw water is parallel delivery.

[0093] S1032: When the first judgment result and the second judgment result are both less than , determining that the raw water delivery method is alternating delivery.

[0094] S11: When the delivery mode is sequential delivery, determining that the one-way valve to be opened is the first preset one-way valve; wherein, after the first preset one-way valve is opened, the raw water delivered by the water inlet pipe 1 can be delivered to the softening device after passing through the two water storage devices 3 in sequence;

[0095] It should be noted that if Figure 3 As shown, the first preset one-way valve does not refer to a single one-way valve, but a one-way valve arranged on a sequential conveying path, so that after opening the first preset one-way valve, it can ensure that the raw water conveyed by the water inlet pipe 1 passes through the two water storage devices 3 in sequence and is then conveyed to the softening equipment, thereby realizing sequential conveying of the raw water, improving the sedimentation and filtration effects of the raw water, thereby conveying stable, low-turbidity raw water to subsequent processes, and improving the water treatment efficiency of the water supply system.

[0096] S12: When the delivery mode is parallel delivery, determining that the one-way valve to be opened is the second preset one-way valve; wherein, after the second preset one-way valve is opened, the raw water delivered by the water inlet pipe 1 can be delivered to the softening device after passing through the two water storage devices 3 arranged in parallel;

[0097] It should be noted that if Figure 2 As shown, the second preset one-way valve does not refer to a single one-way valve, but a one-way valve arranged on a parallel conveying path, so that after opening the second preset one-way valve, it can ensure that the raw water conveyed by the water inlet pipe 1 is respectively conveyed to the softening equipment after passing through the two water storage devices 3 arranged in parallel, thereby realizing the simultaneous conveying of the raw water into the two water storage devices 3 and outputting it to the softening equipment at the same time, thereby improving the raw water conveying efficiency and stable water supply effect, thereby conveying stable, low-turbidity raw water to subsequent processes, and improving the water treatment efficiency of the water supply system.

[0098] S13: When the conveying mode is alternate conveying, determining that the one-way valve to be opened is the third preset one-way valve; wherein, after the first preset one-way valve is opened, the raw water conveyed by the water inlet pipe 1 can be alternately input into the two water storage devices 3, and alternately output to the softening device through the two water storage devices 3;

[0099] It should be noted that if Figure 4 , 5 As shown, the third preset one-way valve does not refer to a single one-way valve, but a one-way valve arranged on the alternating conveying path, so that after opening the third preset one-way valve, it can ensure that the raw water conveyed by the water inlet pipe 1 alternately enters the two water storage devices 3 arranged in parallel, and is alternately output to the softening equipment, thereby realizing alternating conveyance of raw water, improving the conveying efficiency of raw water and stabilizing the water supply effect, thereby conveying stable, low-turbidity raw water to subsequent processes, and improving the water treatment efficiency of the water supply system.

[0100] S20: Determine the opening operation strategy corresponding to the one-way valve to be opened based on the raw water delivery method; specifically, including:

[0101] S21: Acquire real-time monitoring data, and obtain the target opening of the one-way valve to be opened according to the real-time monitoring data and the pre-trained prediction model; wherein the real-time monitoring data includes one or more of the flow rate of raw water transport, the turbidity value of raw water, the current user-side load demand, the turbidity value of the liquid in the water storage device 3, and the flow rate of the water output by the water storage device 3;

[0102] In a preferred example, the present application can be further configured as follows: based on the real-time monitoring data and the pre-trained prediction model, the target opening of the one-way valve to be opened is obtained, including:

[0103] Q=β0+β1V+β2D+β3L+β 4 B+β 5 E;

[0104] Wherein, Q represents the valve opening, V represents the flow rate of raw water, D represents the turbidity value of raw water, L represents the load demand on the user side, B represents the turbidity value of the liquid in the water storage device 3, E represents the flow rate of the water output from the water storage device 3, β 0 , β 1 , β 2 , β 3 , β 4 , β 5 is the model parameter.

[0105] It should be noted that in the technical solution provided in the above embodiment, since the water quality of the raw water and the water quality in the water storage device 3 are dynamically changing, in order to adapt to this dynamic change, the opening of the one-way valve is adaptively controlled according to the real-time monitoring data and the pre-trained prediction model to ensure stable entry into the water storage device 3 and stability in the water storage device 3, avoiding the influence and fluctuation of the water quality during the transportation process, thereby realizing intelligent control effect, improving the filtering effect, extending the service life, and ensuring the stability of the output water quality.

[0106] S22: The conveying method is sequential conveying (such as Figure 3 as shown) or in parallel (as Figure 1 , 2 As shown), when the first preset one-way valve or the second preset one-way valve is controlled to operate at the target opening;

[0107] S23: When the conveying mode is alternating conveying (such as Figure 4 , 5 As shown), based on the turbidity value of the liquid in the water storage device 3, the standing time of the liquid by the water storage device 3 is determined, and the one-way valves corresponding to the first working group and the second working group are determined from the third preset one-way valve according to the standing time, and the one-way valves corresponding to the first working group and the second working group are controlled to alternately operate at the target opening for the standing time; wherein, when the first working group or the second working group is working, one of the water storage devices 3 receives the raw water transported by the water inlet pipe 1, and the other water storage device 3 transports the liquid after standing to the softening equipment.

[0108] In a preferred example, the present application may be further configured as follows: determining the standing time of the liquid in the water storage device 3 based on the turbidity value of the liquid in the water storage device 3, including:

[0109] T = a*B+c;

[0110] Wherein, T is the standing time, B is the turbidity value of the liquid in the water storage device 3, a is the slope coefficient, which indicates the influence of the turbidity value on the standing time, and c is the intercept, which indicates the standing time when the turbidity value is 0.

[0111] In this embodiment, the standing time of the liquid by the water storage device 3 is determined according to the turbidity value of the liquid, so as to achieve more effective impurity precipitation and filtration effects. In practical applications, the coefficients in the algorithm formula can be adjusted according to specific conditions to meet specific treatment requirements and water quality standards.

[0112] S30: Control the water output by the softening device to pass through the oxidation filtration device and the disinfection device in sequence, and obtain the water quality test result output by the disinfection device. After the water quality test result meets the use standard, the water that meets the use standard is supplied to the user or stored.

[0113] like Figure 9-10 As shown, the present application can be further configured as follows in a preferred example: the water storage device 3 includes a box body; the water outlet of the water storage device is connected to the water outlet pipe 2; a protrusion 33 and a partition 31 are provided in the box body, and a coarse grid 32 is connected between the partition 31 and the protrusion 33; the accommodating space inside the box body is divided by the protrusion 33, the partition 31 and the coarse grid 32 to form a collection area 36 and a filtering area 37, the bottom surface of the collection area 36 is lower than the top surface of the protrusion 33, and the filtering area 37 is above the top surface of the protrusion 33, and the box body is also connected to a water inlet pipe 1 for conveying sewage, and the water inlet pipe 1 is connected to the collection area 36;

[0114] The collection area 36 is provided with a fine grid 34, and the fine grid 34 is respectively connected to the partition plate 31 and the inner wall of the box body to divide the filtering area 37 into a primary filtering area 371 and a secondary filtering area 372, and the primary filtering area 371 is located below the fine grid 34, and the secondary filtering area 372 is located above the fine grid 34;

[0115] The two ends of the first delivery pipe are respectively connected to the secondary filtering area 372 and the first temporary storage area, and the first siphon pipe is respectively arranged in the secondary filtering area 372 and the first temporary storage area.

[0116] By adopting the above technical solution, a partition 31 and a coarse grid 32 are arranged in the box body, and the coarse grid 32 is connected to the partition 31, so as to divide the inside of the box body into a collection area 36 and a filtration area 37, and the filtration area 37 is above the top surface of the protrusion 33. At this time, since the bottom of the filtration area 37 is higher than the collection area 36, ​​under the action of gravity, the impurities in the sewage can be initially precipitated, and since the collection area 36 and the filtration area 37 are separated by the partition 31 and the coarse grid 32, the liquid entering the filtration area 37 is further filtered and isolated by the coarse grid 32. At the same time, a fine grid 34 is installed in the filtration area 37, and the fine grid 34 is connected to the partition 31 and the wall of the box body, so that the filtration area 37 can be divided into a primary filtration area. The first filter area 371 and the secondary filter area 372 located above the first filter area 371 receive the liquid filtered by the coarse grid 32 through the first filter area 371, and receive the liquid filtered by the fine grid 34 through the secondary filter area 372, thereby realizing a multi-level real-time filtering effect on the raw sewage through the box body, without the need to use a plurality of devices in combination, thus reducing the equipment cost and the floor space occupied. At the same time, under the action of gravity, impurities can continue to settle downward, thereby ensuring that the liquid in the secondary filter area 372 is the optimal filtered liquid (i.e., the cleanest liquid in the box body), so that after being transported to the subsequent process through the first siphon or the first delivery pipe, the processing difficulty of the subsequent process is reduced and the subsequent processing steps are reduced, thereby greatly improving the sewage treatment efficiency and treatment effect.

[0117] As needed, a pollutant collection port can also be provided at the bottom of the box body, and the pollutant collection port is connected to the collection area 36. A sealing cover is installed on the pollutant collection port. When it is necessary to collect the pollutants in the collection area 36, ​​the sealing cover can be opened to facilitate the discharge and cleaning of the pollutants.

[0118] As shown in the figure, the present application can be further configured in a preferred example as follows: the partition 31 includes an inclined section 311 and a vertical section 312 connected in sequence from top to bottom, the vertical section 312 is arranged parallel to an opposite surface of the box body, the vertical section 312 of the partition 31 is connected to the protrusion 33 through the fine grid 34, and the inclined section 311 is gradually inclined from top to bottom along the direction of the collection area 36;

[0119] As required, the coarse grid 32 is inclined, and the coarse grid 32 is gradually inclined from top to bottom along the direction of the primary filtering area 371;

[0120] As required, the fine grid 34 is arranged obliquely, and the fine grid 34 is arranged obliquely gradually from left to right along the direction of the primary filtering area 371;

[0121] As required, the top surface of the protrusion 33 is inclined, and the top surface of the protrusion 33 is gradually inclined downward from right to left;

[0122] As required, a filter layer 35 is further provided above the fine grid 34 , with a spacing between the filter layer 35 and the fine grid 34 , and the filter layer 35 is located below the first delivery pipe and the first siphon pipe, wherein the filter layer 35 includes filter cloth.

[0123] By adopting the above technical solution, since the partition 31 includes an inclined section 311 and a vertical section 312 connected in sequence from top to bottom, and the vertical section 312 is connected to the protrusion 33 through the fine grid 34, the interior of the box is divided into a collection area 36 and a filtration area 37, and the inclined section 311 is gradually inclined from top to bottom along the direction of the collection area 36 to increase the accommodation space and the collection opening of the collection area 36, ​​so as to facilitate the collection and sedimentation of sewage, prevent impurities and pollutants from entering the filtration area 37, and facilitate the salvage and cleaning of floating objects; in addition, by arranging the coarse grid 32 in an inclined manner, and the coarse grid 32 is gradually inclined from top to bottom along the direction of the collection area 36, The primary filter area 371 is tilted to prevent impurities and pollutants from entering the collection area 36 from the water inlet pipe 1. When they settle downward under the action of gravity, they are not easy to enter the primary filter area 371 domain 37, thereby achieving good filtration of sewage. In addition, since the coarse grid 32 is tilted, filtration in the tilted direction is achieved, which is better than filtration in the horizontal and vertical directions during use, thereby further improving the filtration effect. The fine grid 34 is tilted, and the fine grid 34 is gradually tilted from left to right along the direction of the primary filter area 371. Since the coarse grid 32 is tilted, filtration in the tilted direction is achieved, which is better than filtration in the horizontal and vertical directions during use. Filtering, and by tilting the top surface of the protrusion 33, the top surface of the protrusion 33 is gradually tilted downward from right to left. Under the action of gravity, the impurities in the primary filtration area 371 and the secondary filtration area 372 can accurately settle on the tilted top surface of the protrusion 33 when they settle downward, and slide through the tilted top surface of the protrusion 33 to the collection area 36, ​​so as to achieve the effect of real-time filtration, and ensure that impurities and pollutants can be centrally processed and collected, so as to further improve the sewage filtration and treatment effect; further, by setting a filter layer 35 above the fine grid 34, there is a gap between the filter layer 35 and the fine grid 34, and the filter layer 35 includes a filter cloth, it can be achieved The sewage is effectively filtered. When the water inlet pipe 1 transports the sewage into the box, the sewage first enters the collection area 36. When the sewage level reaches the top surface of the protrusion 33, it is filtered through the coarse grid 32 and then enters the primary filter area 371. When the sewage level in the primary filter area 371 reaches the fine grid 34, it is filtered through the fine grid 34 and reaches below the filter layer 35. After passing through the filter layer 35, it enters the secondary filter area 372, so that it can be transported by the first delivery pipe and sucked by the first siphon pipe to the secondary treatment device for treatment. At the same time, during the working process, impurities and pollutants can be continuously precipitated in the collection area 36, ​​so as to facilitate centralized collection and treatment and achieve multi-level filtering effects.

[0125] By adopting the above technical solution and setting up a reflux pipe, when it is monitored that the liquid does not meet the use standards, it is refluxed through the reflux pipe according to the water quality monitoring results to perform secondary treatment on the liquid to ensure that the discharged liquid is within the provisions of the safe discharge standards.

[0126] It can be understood that the return pipe is provided with a water quality monitoring component, wherein the water quality monitoring component can be equipped with corresponding monitoring instruments according to the processing procedures of the softening equipment, oxidation filtration equipment and disinfection equipment or the monitoring factors of the emission standards, such as turbidity meters, iron and manganese ion monitors, bromide ion monitors, chloride ion monitors, flow monitors and conductivity monitors, etc., to facilitate the corresponding monitoring of the water quality of the output liquid to monitor whether the output water meets the use standards.
