Background technique

Water pollution refers to the pollution caused by the entry of industrial wastewater, domestic sewage and other waste into rivers, lakes, seas and other water bodies, exceeding the self-purification capacity of the water body. This will lead to changes in the physical, chemical, and biological characteristics of the water body, thereby affecting the value of water use. Suspended particulate matter refers to particles suspended in water with a particle diameter between 10nm and 0.1um, including water-insoluble inorganic matter, organic matter and sediment, clay, microorganisms, etc. The content of suspended solids in water is one of the indicators to measure the degree of water pollution.

In recent years, water pollution has become a prominent global environmental problem. In natural water bodies, suspended particulate matter is an important medium for various pollutants to exist in water bodies. Due to the large specific surface area and other related properties of suspended particulate matter, it plays a very important role in the migration and transformation of pollutants in natural water bodies. . Therefore, it is of great significance to study the relevant properties of suspended particulate matter in water bodies to explain the migration, transformation and final fate of pollutants in water bodies. The collection method and collection device of suspended particulate matter in natural water bodies have become the basis of research work on suspended particulate matter. At present, the commonly used method for sampling suspended particulate matter in water is to collect a certain volume of water samples, and then pass through a membrane filter device with a pore size of 0.45 μm to obtain suspended particulate matter in the water body, so that suspended particulate matter with a pore size greater than 0.45 μm is filtered together. , so that its properties change to a certain extent, and ultimately it is difficult to avoid a certain impact on the relevant analysis results of suspended particulate matter. How to obtain suspended particles of different particle sizes is not satisfied by the current visible equipment.
