Description

Technical Field

[0001] The present invention belongs to the technical field of photocatalytic sewage treatment, and in particular relates to an intelligent monitoring method and system based on photocatalytic sewage treatment. Background Art

[0002] Photocatalytic wastewater treatment is a green and environmentally friendly technology that uses photocatalysts to produce strongly oxidizing free radicals under the action of light to degrade organic pollutants in water bodies. Nano-scale semiconductor materials (such as TiO2) are usually used as photocatalysts. Under the irradiation of catalytic light, they are excited to produce electron-hole pairs, which react with water and oxygen to generate active species with strong oxidizing ability, thereby oxidizing organic pollutants into harmless substances such as carbon dioxide and water.

[0003] Photocatalytic wastewater treatment has the advantages of mild reaction conditions, no secondary pollution, and sustainable operation. It is suitable for degrading trace pollutants such as difficult-to-degrade organic matter, dyes, and pesticide residues, and is widely used in industrial wastewater, domestic sewage, and environmental remediation.

[0004] In the existing technology, due to the disturbance caused by the flow of sewage and the continuous changes in the concentration and composition of sewage, it is easy to cause the propagation path of light in the medium to be transmitted less efficiently, making it impossible to focus stably and accurately on the surface of the photocatalyst bed, resulting in a reduction in the effective irradiation area and a decrease in the utilization rate of light energy, which in turn causes a decrease in the efficiency of the catalytic reaction, affecting the degradation rate and treatment effect of organic pollutants.

[0073] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0074] It is understandable that in the existing technology, due to the disturbance caused by the flow of sewage and the continuous changes in the sewage concentration and composition, it is easy to cause the propagation path of light in the medium to be transmitted less efficiently, making it impossible to focus stably and accurately on the surface of the photocatalyst bed, resulting in a reduction in the effective irradiation area and a decrease in the utilization rate of light energy, which in turn causes a decrease in the efficiency of the catalytic reaction, affecting the degradation rate and treatment effect of organic pollutants.

[0075] To solve the above problems, an embodiment of the present invention discloses an intelligent monitoring method and system based on photocatalytic sewage treatment. The method and system perform trial treatment and trial detection of photocatalytic sewage treatment, obtain trial detection data, analyze and judge whether there is catalytic abnormality, and select abnormal catalytic area when there is catalytic abnormality; in the abnormal catalytic area, perform irradiation control and irradiation monitoring of standard reference bed with standard visible light source, obtain irradiation monitoring data; perform point identification on irradiation monitoring data, record point recording data; obtain light source parameter data, calculate photocatalytic correction angle according to the point recording data, and adjust photocatalytic angle according to the photocatalytic correction angle. When there is catalytic abnormality, irradiation control, irradiation monitoring and point identification of standard reference bed with standard visible light source are performed, and then light source equivalent correction angle mapping analysis is performed, photocatalytic correction angle is calculated and photocatalytic angle is adjusted, so that catalytic light can be stably and accurately focused on the surface of photocatalyst bed, ensuring that the effective irradiation area will not be reduced, thereby improving light energy utilization and catalytic reaction efficiency, and ensuring the degradation rate and treatment effect of organic pollutants.

[0076] Specifically, Figure 1 The flowchart of the intelligent monitoring method based on photocatalytic sewage treatment provided by an embodiment of the present invention is shown.

[0077] In a preferred embodiment of the present invention, an intelligent monitoring method based on photocatalytic wastewater treatment is provided, the method specifically comprising the following steps:

[0078] Step S101: perform trial treatment and test of photocatalytic wastewater treatment, obtain test test data, analyze and determine whether there is catalytic abnormality, and if there is catalytic abnormality, select an abnormal catalytic area.

[0079] In an embodiment of the present invention, photocatalytic sewage treatment planning data is received, the photocatalytic sewage treatment planning data is identified, a trial treatment period and multiple trial treatment areas are determined, and during the trial treatment period, photocatalytic trial treatment and trial detection are performed on multiple trial treatment areas, and the trial detection data are obtained and matched with the standard detection data. The trial detection data is numerically compared with the standard detection data to determine whether there is a catalytic anomaly. When it is determined that there is a catalytic anomaly, an abnormal catalytic area is selected from the multiple trial treatment areas.

[0080] It can be understood that during the test process, it is necessary to test the turbidity, chemical oxygen demand and pH value in the water after the photocatalytic test treatment; the standard test data has a standard numerical range corresponding to turbidity, chemical oxygen demand and pH value; the turbidity, chemical oxygen demand or pH value in the abnormal catalytic area is not within the standard numerical range corresponding to the standard test data.

[0084] Step S1012: During the test treatment period, perform photocatalytic test treatment and test detection on the plurality of test treatment areas to obtain test detection data.

[0085] Step S1013: Match standard detection data.

[0086] Step S1014: compare the test data with the standard test data to determine whether there is catalytic abnormality.

[0090] In an embodiment of the present invention, in the abnormal catalytic area, reference space data is planned, and then the standard visible light source and the standard reference bed are spatially arranged according to the reference space data. At the same time, the current light source parameters of the photocatalytic wastewater treatment are obtained. After the spatial arrangement of the standard visible light source and the standard reference bed is completed, the reference irradiation angle of the standard visible light source is convergently adjusted according to the current light source parameters, and then the irradiation of the standard visible light source is controlled, and the entire irradiation process is photographed to obtain irradiation monitoring data.

[0091] It can be understood that the reference space data includes data such as light source height and reference isolation distance; the light source height is the height distance between the standard visible light source and the standard reference bed, and is also the height distance between the photocatalytic light source and the photocatalyst bed; the reference isolation distance is the minimum distance between the standard visible light source and multiple photocatalytic light sources.

[0092] It can be understood that the current light source parameters record the catalytic irradiation angle of the photocatalytic light source in the abnormal catalytic area relative to the photocatalyst bed plane under the current state; performing convergent irradiation control of the standard visible light source on the standard reference bed is a process of adjusting the reference irradiation angle of the standard visible light source relative to the standard reference bed plane so that the reference irradiation angle is consistent with the catalytic irradiation angle, and performing irradiation control on the standard visible light source.

The actual irradiation point is determined from the visible light spot area, and the target irradiation point is determined from the standard reference area. A representative monitoring coordinate system is constructed. In the representative monitoring coordinate system, the coordinates of the actual irradiation point and the target irradiation point are determined, and the corresponding coordinate data is recorded to obtain point record data.

[0104] It can be understood that the actual irradiation point is the center point of the visible light spot area; the target irradiation point is the center point of the standard reference area.

The light source parameter data, point recording data, and reference space data are combined to calculate the photocatalytic correction angle. Then, according to the photocatalytic correction angle, a corresponding correction adjustment signal is generated. Then, according to the correction adjustment signal, the angle of the photocatalytic light source in the abnormal catalytic area is adjusted accordingly, so that the catalytic light can be stably and accurately focused on the surface of the photocatalyst bed. Specifically, the calculation formula of the photocatalytic correction angle is:
