Application of peristaltic pump in sewage treatment
In recent years, with the continuous advancement of industrialization and urbanization, the social economy has developed rapidly, but the subsequent pollution problem has become an important issue that needs to be solved urgently. Sewage treatment has gradually become indispensable for economic development and water resources protection. component. Therefore, vigorously developing sewage treatment technology and industrialization level is an important way to prevent water pollution and alleviate water shortages. In this process, the pump head of the peristaltic pump has also played a big factor. Maybe you don't know much about the purpose of the peristaltic pump, but I believe that after reading the following article, you will understand the role of the peristaltic pump.
Sewage treatment overview:
Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Modern sewage treatment technology is divided into primary, secondary and tertiary treatment according to the degree of treatment.
The primary treatment mainly removes the suspended solid matter in the sewage. Physical methods are commonly used. After the first-level treatment, BOD can generally be removed by about 30%, which does not meet the discharge standard. The first-level treatment belongs to the pretreatment of the second-level treatment.
The secondary treatment mainly removes the colloidal and dissolved organic matter (BOD, COD) in the sewage. Generally, the sewage that reaches the secondary treatment can meet the discharge standard, and the activated sludge method and the biofilm treatment method are commonly used.
Tertiary treatment to further remove certain special pollutants, such as phosphorus, nitrogen, and organic pollutants that are difficult to biodegrade, inorganic pollutants, and pathogens. The main methods include biological nitrogen and phosphorus removal method, coagulation precipitation method, sand filtration method, activated carbon adsorption method, ion exchange method and electroosmosis analysis method.
The working princIPLe of peristaltic pump:
The peristaltic pump is a kind of precision transmission equipment. It is assembled by the driver, the pump head of the peristaltic pump and the silicone tube of the peristaltic pump. The liquid is transferred by squeezing the silicone tube by the pump roller. Its transmission precision and hygiene are widely Used in sewage treatment, pharmaceutical industry, etc.
