Rivers are important water resources in nature, which not only provide important support for human life and social and economic development, but also provide habitats for many organisms. However, due to the increasing human activities and the intensification of environmental pollution, the problem of river water quality is becoming more and more prominent, especially the content of suspended solids in rivers.
Suspended solids refer to particulate matter that is suspended in water and difficult to settle, including organic and inorganic matter, such as sediment, algae, microorganisms, etc. The high content of suspended solids will have a serious impact on the ecosystem and water quality of the river, such as affecting the transparency of light, blocking the channel of the water body, increasing the turbidity of the water body, etc.
In order to solve the problem of river suspended solids content determination, scientists have developed an instrument called the river suspended solids analyzer. Through a series of physical and chemical analysis methods, the meter can accurately and quickly measure the amount of suspended solids in the river, and then provide data support to help people understand the changes in river water quality and the degree of water pollution.
The operating principle of the river suspended solids analyzer is based on the scattering of light by the suspended solids. It emits a beam of light of a specific wavelength that hits the suspended solids in the water sample, which scatters the light. The meter collects the scattered light and calculates the amount of suspended solids based on the change in the intensity of the light. This method has very high accuracy and sensitivity, and is able to measure the amount of suspended solids in different water samples in a short period of time.
The river suspended solids tester is usually composed of a light source, an optoelectronic device, a photoelectric sensor, a computer and a display. The light source is the core component of the measuring instrument, and the beam it provides must have a certain intensity and stability to ensure the accuracy of the measurement results. The optoelectronic device is responsible for receiving the light emitted by the light source, converting the optical signal into an electrical signal, and transmitting it to the photoelectric sensor. After receiving the electrical signal, the photoelectric sensor will perform a series of signal processing and calculations, and then send the results to the computer for display and saving.
The river suspended solids analyzer has many advantages. First of all, it is easy to operate, does not require complex operating processes and specialized technical knowledge, and can be measured even by people without relevant backgrounds. Second, the analyzer is able to provide real-time measurement results, reducing the time and cost of traditional laboratory analysis. In addition, the small size of the meter makes it easy to carry and move, and it can be measured in different rivers and waters.
There are also some limitations to river suspended solids analyzers. First of all, the tester has high requirements for the stability of light, and if the measurement conditions are not ideal, the accuracy of the measurement results may be affected. Secondly, the tester has strict requirements for the treatment of water samples, which requires pretreatment and filtration to exclude interference from other substances to the measurement results. Thirdly, the adaptability of the tester in different waters is limited, and it needs to be adjusted and corrected according to different environments and situations.
