Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a reflux pipeline control system based on sewage treatment. Background Art

[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. At present, sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. For example, the sewage of cigarette factories mainly comes from three parts: the first part is the water for expanding tobacco and washing stems. Although the amount of water is not large, the concentration is very high, and it is full of nicotine and phenolic substances. The second part is white glue wastewater, the main component of which is cigarette paper adhesive, which is turbid white and has a high COD. The third part is the flushing wastewater of the spice workshop, the main components of which are spices, flavors and engine oil. If the three parts of wastewater are combined, the turbidity will be very high. At present, with the development of sewage treatment related technologies, the sewage treatment equipment used to treat sewage will be configured in the water quality detection system for detection after treating the sewage, so that the sewage that meets the standards will be further discharged, and the sewage that does not meet the standards will be returned to the sewage treatment equipment through the return pipe for purification again, until the treated sewage meets the sewage discharge standards and is discharged. Whether the treated sewage meets the turbidity level in the discharge standard is an important evaluation parameter for sewage treatment. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a return pipe control system based on sewage treatment, which solves the technical problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A reflux pipeline control system based on sewage treatment, comprising:

[0006] The control terminal is the main control end of the system and is used to issue execution commands; the acquisition module is used to acquire the image data of the sewage that has been treated in the sewage treatment equipment; the analysis module is used to receive the sewage image data and analyze the turbidity of the sewage that has been treated based on the sewage image data; the decision module is used to set the sewage return judgment threshold, receive the analysis result of the turbidity of the sewage that has been treated in the analysis module, and decide whether to transmit the treated sewage back to the sewage treatment equipment by comparing the analysis result with the sewage return judgment threshold; the reset module is used to reset the system to jump to the acquisition module operation stage; the evaluation module is used to evaluate the sewage treatment capacity of the sewage treatment equipment;

[0007] The control terminal is interactively connected to a collection module via a local area network, the collection module is interactively connected to an enhancement unit and a forwarding unit at a lower level via a local area network, the collection module is interactively connected to an analysis module via a local area network, the analysis module is interactively connected to a recording unit via a local area network, the analysis module is interactively connected to a decision module, a reset module and an evaluation module via a local area network, the collection module is interactively connected to the reset module via a local area network, and the evaluation module is interactively connected to the recording unit via a local area network.

[0008] Furthermore, the acquisition module is provided with submodules at the lower level, including:

[0009] An enhancement unit, used for receiving the sewage image data collected by the collection module and performing enhancement processing on the sewage image data;

[0010] A forwarding unit, used to obtain the sewage image data that has completed the enhancement processing in the enhancement unit, and forward the sewage image data to the analysis module;

[0011] The acquisition module is provided with an acquisition logic for image data of the treated sewage, and the acquisition module performs continuous reception and enhancement processing on the treated sewage based on the acquisition logic.

[0012] Furthermore, the logic for collecting the treated sewage image data set in the collection module is:

[0013] Logic 1: Measure the volume of the treated sewage, and calculate the time required to discharge the treated sewage based on the discharge efficiency of the treated sewage;

[0014] Logic2: Obtain the discharge time of the treated sewage, so that the collection module collects no less than three groups of treated sewage image data, and the collection interval of each group of image data is equal, and the treated sewage is collected once at the start and end timestamps of the discharge;

[0015] Among them, a transfer station is set at the discharge end of the sewage treatment equipment, which is used to receive the treated sewage and discharge the treated sewage in a centralized manner. The image data of the treated sewage is collected based on the collection module during the process of transmitting the treated sewage from the sewage treatment equipment to the transfer station.

[0016] Furthermore, the enhanced processing logic of the processed sewage image data is expressed as:

[0017] g(x,y)=c×log(1+f(x,y));

[0018] Where: g(x, y) is the pixel value of the treated sewage image at the coordinate (x, y); c is a constant; f(x, y) is the pixel value of the enhanced treated sewage image at the coordinate (x, y);

[0019] Among them, 49≥c>0, based on the above formula, the pixel value of each position pixel in the treated sewage image is adjusted to output enhanced treated sewage image data.

[0020] Furthermore, the processed sewage image data received by the analysis module is enhanced processed sewage image data, and the analysis module runs continuously, receiving a set of enhanced processed sewage image data each time;

[0021] When analyzing the turbidity of the enhanced sewage image data after treatment, the analysis module applies any one of a grayscale histogram analysis algorithm, an edge detection algorithm, and an image segmentation algorithm to analyze the turbidity of the enhanced sewage image data after treatment.

[0022] Furthermore, the analysis module is internally provided with a sub-module, including:

[0023] A recording unit, used for receiving the turbidity analysis result of the sewage image data enhanced and processed in the analysis module, marking the analysis result with the starting timestamp when the analysis module performs the analysis operation, and recording the analysis result with the timestamp;

[0024] Among them, the recording module is set with a data iteration logic, and the data iteration logic is: the number of analysis result groups recorded by the recording unit is always not less than the set number of groups, the set number of groups is a fixed value set by the system user, the set number of groups is not less than three groups, and the analysis results recorded by the recording unit are always the analysis results of the set number of groups most recently analyzed by the analysis module.

[0026] When the operation result of the decision module is no, the stop valve operates to connect the transfer worker in the three-way sewage return pipe located at the other end of the three-way sewage return pipe, and the treated sewage is discharged through the other end.

[0027] Furthermore, the reset module is triggered once each time the decision module runs and the decision result is yes.

[0028] Furthermore, during the operation phase of the evaluation module, the turbidity analysis result of the enhanced treated sewage image data with a time stamp is obtained in the recording unit, and the sewage treatment capacity of the sewage treatment equipment is evaluated based on the turbidity analysis result;

[0029] The sewage treatment capacity of the sewage treatment equipment is expressed as:

[0030]

[0031] In the formula: λ1, λ2, λ3 are the turbidity values ​​of the first, second and third groups of sewage recorded in the recording unit based on time series; λ0 is the maximum allowable turbidity judgment value of discharged sewage;

[0032] Among them, based on the above formula, if any one of the formulas (1) and (2) is established, it means that the sewage treatment capacity of the sewage treatment equipment is poor. On the contrary, if both the formula (1) and (2) are not established, it means that the sewage treatment capacity of the sewage treatment equipment is good.

[0033] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0034] The present invention provides a return pipe control system based on sewage treatment. During operation, the system collects sewage image data by setting logic, and provides sewage return decision logic for the sewage return pipe based on the enhancement and turbidity analysis of the sewage image data, thereby ensuring the stable return of sewage that does not meet the discharge standards.

[0035] At the same time, during the operation of the system, the sewage treatment capacity of the sewage treatment equipment can be monitored and evaluated in real time, so that the staff at the sewage treatment end can pay attention to the performance dynamics of the sewage treatment equipment in time, manage the sewage treatment equipment, adaptively maintain the sewage treatment equipment, and ensure the sewage treatment capacity of the sewage treatment equipment.

[0054] A recording unit, used for receiving the turbidity analysis result of the sewage image data enhanced and processed in the analysis module, marking the analysis result with the starting timestamp when the analysis module performs the analysis operation, and recording the analysis result with the timestamp;

[0055] The recording module is provided with a data iteration logic, which is: the number of analysis result groups recorded by the recording unit is always no less than the set number of groups, the set number of groups is a fixed value set by the system end user, the set number of groups is no less than three groups, and the analysis result recorded by the recording unit is always the analysis result of the set number of groups analyzed by the analysis module the most recently;

[0057] A three-way sewage return pipe is arranged between the transfer station and the sewage treatment equipment.

[0063] Through the operation of the system in the above embodiment, an intelligent control effect is brought to the sewage return pipe in the sewage treatment work.

[0064] Embodiment 2:

[0065] In terms of specific implementation, based on Example 1, this example refers to Figure 1 A return pipe control system based on sewage treatment in Example 1 is further described in detail:

[0066] The enhanced processing logic of the treated sewage image data is expressed as:

[0067] g(x,y)=c×log(1+f(x,y));

[0068] Where: g(x, y) is the pixel value of the treated sewage image at the coordinate (x, y); c is a constant; f(x, y) is the pixel value of the enhanced treated sewage image at the coordinate (x, y);

[0069] Among them, 49≥c>0, based on the above formula, the pixel value of each position pixel in the treated sewage image is adjusted to output enhanced treated sewage image data.

On the contrary, if both the formula (1) and (2) are not established, it means that the sewage treatment capacity of the sewage treatment equipment is good.

[0083] Through the above logic formula, the evaluation logic of the sewage treatment capacity of the sewage treatment equipment is further limited.

[0084] In summary, during the operation of the system in the above embodiment, the system collects sewage image data by setting logic, and provides sewage return decision logic for the sewage return pipe based on the enhancement and turbidity analysis of the sewage image data, thereby ensuring the stable return of sewage that does not meet the emission standards; at the same time, during the operation of the system, it can also synchronously monitor and evaluate the sewage treatment capacity of the sewage treatment equipment in real time, so that the staff at the sewage treatment end can pay attention to the performance dynamics of the sewage treatment equipment in a timely manner, so as to manage the sewage treatment equipment, adaptively maintain the sewage treatment equipment, and ensure the sewage treatment capacity of the sewage treatment equipment.
