Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, and in particular to a sewage outfall water quality monitoring device based on a full spectrum. Background Art

[0002] Sewage outlet water quality monitoring equipment is widely used in urban sewage treatment, industrial wastewater treatment, agricultural non-point source pollution control and other fields. By real-time monitoring of key indicators such as pH value, dissolved oxygen, turbidity, chemical oxygen demand (COD), ammonia nitrogen, etc. in sewage, the equipment can provide a basis for whether sewage discharge meets the standards and ensure that sewage discharge meets relevant national and local environmental protection standards.

[0003] In principle, sewage outlet water quality monitoring equipment is based on sensor technology and automation control principles. The sensor converts water quality parameters into electrical signals or other measurable signals through direct contact with the water sample, and then these signals are transmitted to the measurement system for analysis and processing.

[0004] Although the existing sewage outlet water quality monitoring equipment has played an important role in the field of environmental protection, there are still some problems and shortcomings:

[0005] (1) Technical accuracy issues: In some cases, the detection accuracy of the equipment may be limited and unable to accurately measure certain water quality parameters. This may be due to the accuracy limitations of the sensor itself, interfering substances in the water sample, or the influence of the measurement environment.

[0006] (2) Complex operation and maintenance: Some high-end equipment has complex operation procedures and maintenance requirements, requiring professional personnel to operate and maintain it. This increases the cost of use and may limit the application of the equipment in non-professional environments.

[0007] (3) Equipment selection: In practical applications, due to differences in wastewater composition and discharge standards in different industries and regions, it is particularly important to select appropriate monitoring equipment. However, the equipment selection on the market is often lacking in specificity, resulting in some equipment being unable to meet specific needs.

[0008] (4) Insufficient data processing and analysis capabilities: Existing equipment may have limitations in data processing and analysis, and cannot fully mine and utilize monitoring data. This may lead to inaccurate and incomplete assessments of water quality conditions.

[0009] These problems and shortcomings exist mainly due to the following reasons:

[0010] (1) Technical limitations: Current sensor technology and automatic control technology still need to be further developed to improve the detection accuracy and stability of the equipment.

[0011] (2) Lagging data processing technology: Existing data processing and analysis methods may not be able to adapt to large-scale, high-dimensional monitoring data, resulting in insufficient data processing capabilities. Utility Model Content

[0018] The wireless communication module is connected to the spectrometer and is used to send the digital signal to a cloud server. The cloud server receives the digital signal and analyzes the digital signal to extract water quality parameter information.

[0019] Furthermore, the optical system includes lenses and reflectors arranged in sequence along a preset optical path.

[0023] Furthermore, the power module is a lithium battery.

[0024] Furthermore, the pretreatment device includes a filtering component and a dilution component.

[0025] The beneficial effects of the utility model are embodied in:

[0026] (1) Improvement in productivity and quality

This makes water quality monitoring faster and more accurate, providing strong support for water quality assessment and pollution control.

[0030] (3) Reduction of energy consumption and costs

[0031] The device does not require the use of chemical reagents and additional pretreatment equipment, reducing energy consumption and raw material consumption. At the same time, due to the use of full-spectrum technology, the device can detect multiple pollutants at the same time, reducing the equipment and labor costs required for multiple tests. These cost-saving measures make the device more economical in long-term use.

[0032] (4) Ease of operation and control

[0033] The device adopts an integrated design, compact structure and easy operation. Users can complete the water quality monitoring task through simple operations without complicated pretreatment and operation steps. In addition, the device is equipped with an intelligent control system that can realize automatic detection and data processing, reducing the difficulty of operation and labor intensity.

[0034] (5) Control and improvement of environmental pollution

[0035] This device can monitor the water quality changes at the sewage outlet in real time, and promptly detect and deal with water quality problems. By providing accurate water quality data, the device helps to formulate more effective pollution control plans and improve the quality of the water environment. At the same time, since no chemical reagents are required, the device itself will not cause secondary pollution to the environment.

[0036] In summary, compared with the existing technology, this device has significant advantages in terms of yield, quality, accuracy, efficiency, cost, ease of operation, and environmental pollution control. These advantages make this device have broad application prospects and important practical value in the field of water quality monitoring and analysis. BRIEF DESCRIPTION OF THE DRAWINGS
