Description

Technical Field

[0001] This application relates to the field of wastewater treatment and monitoring technology, specifically to a water quality monitoring system applied to wastewater treatment. Background Technology

[0002] Monitoring wastewater treatment is a core element in ensuring treatment effectiveness, environmental safety, process optimization, and compliance. Real-time adjustments and optimizations to the wastewater treatment process based on real-time data can improve the wastewater purification rate. Therefore, this application proposes a water quality monitoring system for wastewater treatment.

[0003] Existing technology, such as the invention application patent with announcement number CN119774752B, discloses a water quality monitoring system for wastewater treatment, which relates to the field of wastewater quality monitoring technology. Specifically, it includes monitoring and analyzing the uniformity of water quality before microbial addition, confirming the wastewater treatment mode, analyzing the microbial combination scheme and microbial addition scheme for each depth layer of wastewater treatment during stratified treatment, and analyzing the microbial combination scheme and overall microbial addition scheme for overall treatment. After adding microorganisms, water quality is monitored and corresponding adjustments are made to ensure the uniformity and consistency of water quality treatment progress. This helps maintain the stability of the microbial growth environment, allowing microorganisms to work continuously and efficiently in a relatively stable environment, improving the decomposition rate of pollutants in wastewater, ensuring the stability of effluent water quality, reducing the difficulty of subsequent microbial control and regulation, improving the overall wastewater treatment effect, and reducing the waste of microorganisms and operating costs.

[0004] Existing technology, such as the invention patent application with publication number CN117303675A, discloses a wastewater treatment system and method. The wastewater treatment system includes an equalization tank, a biological selection tank, a biological rotating disc treatment device, an intermediate water tank, a high-efficiency sedimentation tank, a filter cloth rotating disc filtration device, a sludge tank, and a disinfection tank. A water supply pipeline connects the biological selection tank and the equalization tank. The biological rotating disc treatment device includes a body, with the rotating disc assembly located within the contact reaction tank of the body. The intermediate water tank is connected to the effluent tank of the biological rotating disc treatment device. The high-efficiency sedimentation tank includes a chemical coagulation zone and an inclined tube sedimentation zone. A chemical dosing device is located upstream of the chemical coagulation zone. The filter cloth rotating disc filtration device includes a filter bed, with a rotating disc assembly rotatably installed inside the filter bed. A bottom cleaning device is provided at the bottom of the filter bed. A sludge discharge pipeline connects the sludge tank to the high-efficiency sedimentation tank and the filter cloth rotating disc filtration device. This invention can effectively treat wastewater, with a safe and environmentally friendly treatment process, low cost, high treatment efficiency, and good treatment effect.

[0005] The above-mentioned solutions have the following technical problems: Current technologies mainly analyze the microbial combination scheme and microbial dosing scheme, but do not consider that relying solely on microorganisms cannot effectively remove impurities from wastewater. Similarly, current technologies do not consider the analysis of stirring direction and speed during treatment. Blindly stirring the wastewater will result in uneven distribution of microorganisms or chemical agents, thus failing to achieve the desired purification effect. At the same time, excessively fast stirring speed may prevent microorganisms and chemical agents from fully reacting with impurities, or even destroy flocculent substances in the water, leading to secondary pollution of the wastewater. Conversely, excessively slow stirring speed will lead to a decrease in the purification rate. The current technology's neglect of these aspects will not only lead to a decrease in wastewater purification rate, but also increase purification costs. Summary of the Invention

[0006] The purpose of this application is to provide a water quality monitoring system for wastewater treatment, which solves the problems existing in the background technology.

[0007] To solve the above-mentioned technical problems, this application adopts the following technical solution: This application provides a water quality monitoring system for sewage treatment, including: a sedimentation treatment module: used to detect the sewage currently discharged from the sewage treatment plant, obtain the composition and content of each soluble impurity and each insoluble impurity in the sewage, and perform sedimentation treatment on the sewage to obtain sewage to be purified.

[0008] Purification scheme analysis module: This module analyzes the wastewater discharged from the wastewater treatment plant in the past to obtain a purification scheme prediction model, and then analyzes to obtain the optimal purification scheme for the wastewater to be purified.

[0009] Purification monitoring module: Used to purify the wastewater to be purified according to the optimal purification scheme, and to divide the wastewater to be purified in the purification tank into zones. Then, based on the density analysis of each chemical agent, the aggregation areas of each chemical agent in the wastewater to be purified are obtained, thereby monitoring the content of each soluble impurity in each zone, determining whether the wastewater to be purified should be uniformly treated, thereby analyzing the uniform treatment method of the wastewater to be purified, and analyzing the diffusion of each chemical agent to obtain the uniform treatment rate of the wastewater to be purified.

[0010] The beneficial effects of this application are as follows: 1. This application provides a water quality monitoring system for wastewater treatment, which improves the wastewater recovery rate by sedimenting the wastewater discharged from the wastewater treatment plant and then dewatering the sedimented sludge. Then, the optimal purification scheme for the wastewater to be purified is obtained through a purification scheme prediction model, thereby balancing the relationship between wastewater purification rate and reagent cost. Finally, during the purification process, the content of each dissolved impurity and the concentration of each chemical agent in each area of ​​the purification tank are monitored to determine whether the wastewater should be uniformly treated. Then, the aggregation area of ​​each chemical agent is determined according to the performance of each chemical agent, and the uniform treatment method corresponding to each chemical agent is obtained through analysis. Finally, the uniform treatment rate corresponding to each chemical agent is output according to the wastewater uniform treatment rate decision model, thereby achieving a balance between purification effect and energy consumption cost.

[0011] 2. This application removes non-dissolved impurities from wastewater discharged from waterworks through sedimentation treatment, laying the foundation for subsequent wastewater purification. Based on the purification scheme prediction model, a personalized purification scheme adapted to the characteristics of the wastewater is output, improving the stability of wastewater purification. Compared with staff adding chemical agents based on experience, the purification scheme obtained through the purification scheme prediction model can minimize the waste of agents and energy consumption, balance the relationship between purification rate and purification cost, and provide a data foundation for subsequent purification process upgrades by transforming from experience-driven to data-driven approaches.

This application monitors the water quality and chemical concentration in each area of ​​the purification tank during the purification process, thereby uniformly treating each clustered area. Based on the distribution characteristics of the chemicals, the areas that need to be treated are identified, avoiding the waste of chemicals and energy caused by blind stirring. At the same time, based on the location of the clustered areas, the method and speed of uniform treatment are optimized to ensure the purification effect while avoiding ineffective power consumption.

[0013] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] Figure 1 This is a schematic diagram of the system structure connection of this application. Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Reference Figure 1 As shown, this application provides a water quality monitoring system for wastewater treatment, including the following modules: a sedimentation treatment module: used to detect the wastewater currently discharged from the wastewater treatment plant, obtain the composition and content of each soluble impurity and each insoluble impurity in the wastewater, and perform sedimentation treatment on the wastewater to obtain wastewater to be purified.

[0017] It should be noted that the soluble impurities include inorganic ions, heavy metal ions, and dissolved gases, etc.; the insoluble impurities include suspended solids, microorganisms, and adhesive substances, etc.

[0018] In a specific example, the wastewater sedimentation treatment process is as follows: First, the wastewater is pretreated using a bar screen filtration method and a grit chamber treatment method, and the pretreated wastewater is discharged into a sedimentation tank. At the same time, flocculants are added to the wastewater. After the wastewater has settled in the sedimentation tank, the upper layer of wastewater is discharged, and the sludge at the bottom of the sedimentation tank is dewatered. The wastewater obtained after the sludge dewatering treatment is mixed with the discharged upper layer of wastewater to obtain the wastewater to be purified.

[0019] It should be noted that the aforementioned bar filtration method and grit chamber treatment method are existing treatment technologies, the purpose of which is to remove large impurities in wastewater that interfere with the sedimentation process, and will not be elaborated further here.

[0020] Purification scheme analysis module: This module analyzes the wastewater discharged from the wastewater treatment plant in the past to obtain a purification scheme prediction model, and then analyzes to obtain the optimal purification scheme for the wastewater to be purified.

[0021] In a specific example, the analysis of historical wastewater discharged from the wastewater treatment plant to obtain a purification scheme prediction model involves the following steps: Wastewater samples from the wastewater treatment plant's historical discharge are obtained from a sampling center and designated as test wastewater samples. Each test sample is divided into several portions to obtain sub-samples. A water quality sensor is used to detect the content of soluble impurities in each sub-sample. Based on the content of soluble impurities in each sub-sample, the composition of each chemical agent to be added is determined. Each dosage of each chemical agent is added to each sub-sample. After the chemical samples in each sub-sample have completely reacted, the water quality sensor is used again to detect the content of soluble impurities in each sub-sample. The purification rate of each dosage of each chemical agent corresponding to each sub-sample of the test sample is recorded. Simultaneously, the complete reaction time and purification cost of each sub-sample of the test sample are recorded. Based on this, each test sample is tested, and the purification rate, complete reaction time, and purification cost of each dosage of each chemical agent corresponding to each sub-sample of the test sample are recorded as test data.

[0022] Based on the obtained test data, a mapping model between purification scheme and purification effect is constructed. First, the test data is normalized and input into the neural network model. The neural network model is then trained to obtain a purification scheme prediction model.

[0023] It should be noted that the normalization process and neural network model mentioned are existing technologies, and therefore will not be described in detail.

[0024] In a specific example, the optimal purification scheme for the wastewater to be purified is further analyzed. The specific analysis process is as follows: the composition and content of each soluble impurity in the wastewater to be purified are collected by various water quality monitoring devices, and then the composition and content of each soluble impurity in the wastewater to be purified are input into the purification scheme prediction model. With the cost minimization under the premise of achieving the purification rate standard as the constraint, the optimal purification scheme for the wastewater to be purified is output through the purification scheme prediction model.

[0025] It should be noted that the water quality monitoring equipment includes multi-parameter water quality analyzers, conductivity instruments, spectrophotometers, and TOC analyzers, etc.

[0026] It should be noted that the costs mentioned include time costs and chemical reagent costs. After normalizing the time costs and chemical reagent costs, the calculation formula is as follows: Calculate the cost assessment coefficient The larger the cost assessment coefficient, the higher the cost required for purification. Here, t represents the normalized data of time cost, and w represents the normalized data of chemical agent cost. Time cost represents the sufficient reaction time between soluble impurities in wastewater and the corresponding chemical agent, and chemical agent cost represents the total cost of all chemical agents used in wastewater purification.

[0027] Purification monitoring module: Used to purify the wastewater to be purified according to the optimal purification scheme, and to divide the wastewater to be purified in the purification tank into zones. Then, based on the density analysis of each chemical agent, the aggregation areas of each chemical agent in the wastewater to be purified are obtained, thereby monitoring the content of each soluble impurity in each zone, determining whether the wastewater to be purified should be uniformly treated, thereby analyzing the uniform treatment method of the wastewater to be purified, and analyzing the diffusion of each chemical agent to obtain the uniform treatment rate of the wastewater to be purified.

[0028] In a specific example, the wastewater to be purified in the purification tank is divided into zones, and the aggregation areas of each chemical agent in the wastewater to be purified are obtained based on the density analysis of each chemical agent. The specific analysis process is as follows: the purification tank is divided into zones based on a preset depth, and each zone is numbered. At the same time, the density of each chemical agent is obtained from the product manual, and the density of the wastewater to be purified is measured using a digital density meter. Then, the aggregation areas of each chemical agent in the wastewater to be purified are determined by the density difference between each chemical agent and the wastewater to be purified.

[0029] It should be noted that the preset depth is set by the relevant staff and no specific restrictions are imposed here.

[0030] In a specific example, the process of monitoring the content of soluble impurities in each area to determine whether the wastewater to be purified should be treated uniformly is as follows: After adding a chemical agent to the water purification tank, the chemical agent is designated as the target chemical agent, and the soluble impurities purified by the chemical agent are designated as target soluble impurities. The content of soluble impurities and the concentration of the target chemical agent in each area are collected in real time using various water quality monitoring devices and chemical agent concentration monitoring devices. When the content of soluble impurities and the concentration of the target chemical agent in a certain area both meet the standards, the process is complete. The area is marked as a purified area, and the purified water from the purified area is discharged. When the content of the target soluble impurities in a certain area exceeds the standard, the concentration difference of the target chemical agent in each area is compared with the set threshold of the concentration difference of the chemical agent. When the concentration difference of the target chemical agent in each area is less than the set threshold of the concentration difference of the chemical agent, the wastewater to be purified is not uniformly treated. Otherwise, the area with the highest concentration of the target chemical agent is marked as the area to be treated. Based on this, the areas to be treated after the wastewater to be purified is added with each chemical agent are obtained.

[0031] It should be noted that the chemical reagent concentration monitoring equipment includes online refractometers and online chlorine dioxide monitors, etc.

[0032] It should be noted that the threshold for the concentration difference of the chemical agents is set by the relevant personnel. The smaller the threshold for the concentration difference of the chemical agents, the higher the uniform treatment effect of the wastewater to be purified, and the better the purification effect.

[0033] In a specific example, the phrase "draining the purified water from the purified area" means that while keeping the water level in the water purification tank stable, the drain outlet at the bottom of the purified area is opened to drain the purified water from the purified area.

[0034] In a specific example, the method for uniformly treating the wastewater to be purified is analyzed and the specific process is as follows: any area to be treated is recorded as the target area to be stirred. If the target area to be stirred is the bottom or top layer of the water purification tank, the wastewater to be purified in each area of ​​the water purification tank is extracted to another purification tank in order from top to bottom.

[0035] If the target area to be stirred is any area in the water purification tank other than the bottom and top layers, then extend the stirring equipment to half of the target area to be stirred, and stir the target area from top to bottom according to the optimal stirring speed corresponding to the target chemical agent.

[0036] Based on this, the uniform treatment method for the wastewater to be purified can be analyzed.

[0037] It should be noted that for chemical agents that accumulate in the bottom or top layer of the water purification tank, the wastewater to be purified in each area of ​​the water purification tank is extracted to another purification tank in order from top to bottom. Due to the density relationship between the chemical agents and the wastewater, the chemical agents will diffuse in the purification tank, fully reacting with the impurities, while avoiding problems such as floc destruction and energy consumption costs caused by excessive stirring.

[0038] In a specific example, the uniform treatment rate of the wastewater to be purified is obtained by analyzing the diffusion of each chemical agent. The specific process is as follows: First, the uniform treatment method is determined according to the location of each area to be treated in the wastewater to be purified.

[0039] Then, the density of each chemical agent to be treated in each treatment area and the density of the current wastewater to be purified are input into the wastewater uniform treatment rate decision model to obtain the uniform treatment rate of the wastewater to be purified, so as to uniformly treat each wastewater to be purified based on the uniform treatment method and uniform treatment rate.

[0040] In a specific example, a decision model for uniform wastewater treatment rate is analyzed and obtained. The specific process is as follows: Wastewater samples from the wastewater treatment plant's historical discharge are obtained from the sampling center and recorded as wastewater samples to be treated. Chemical agents of different densities are added to each wastewater sample to be treated, so that the chemical agents accumulate in different areas of each sample to determine the uniform treatment method for each sample. A sample to be treated is divided into several sub-samples, and each sub-sample is treated at a different uniform treatment rate. After the reaction is complete, the purification rate of each sample is recorded. Based on this, the purification rate of each sub-sample of each sample to be treated at each uniform treatment rate can be tested. The density of each sample to be treated, the density of each chemical agent, the uniform treatment method, the uniform treatment rate, and the corresponding purification rate are substituted into the neural network model. The optimal uniform treatment rate is solved with the highest purification rate as a constraint. Based on this, the decision model for uniform wastewater treatment rate is trained.

[0041] This application provides a water quality monitoring system for wastewater treatment. It improves wastewater recovery rate by sedimentation of wastewater discharged from wastewater treatment plants and dewatering the sedimented sludge. A purification scheme prediction model is used to analyze and determine the optimal purification scheme for the wastewater, balancing the wastewater purification rate with reagent costs. During the purification process, the system monitors the content of dissolved impurities and the concentration of various chemical reagents in different areas of the purification tank to determine whether uniform treatment of the wastewater is necessary. Based on the properties of each chemical reagent, the system identifies the aggregation areas of each reagent, thus determining the corresponding uniform treatment method. Finally, a wastewater uniform treatment rate decision model outputs the uniform treatment rate corresponding to each chemical reagent, achieving a balance between purification effect and energy consumption cost.

[0042] The above content is merely an example and illustration of the concept of this application. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the inventive concept or exceed the scope defined in this application, they should all fall within the protection scope of this application.
