The Application Of Peristaltic Pump in Waste Water 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. 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. The secondary treatment mainly removes the colloidal and dissolved organic matter 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. The tertiary treatment is to further remove certain special pollutants, such as phosphorus, nitrogen, and organic pollutants that are difficult to biodegrade, inorganic pollutants, and pathogens.
An accurate and reliable choice


Peristaltic pumps are widely used in sewage treatment processes due to their own characteristics. Safe, accurate and efficient chemical dosage and delivery are the goals of every sewage treatment operation, which requires pumps designed to handle the most demanding applications.
The peristaltic pump has strong self-priming ability and can be used to raise the water level of the sewage to be treated. The peristaltic pump has low shear force and will not destroy the effectiveness of the flocculant when transporting shear-sensitive flocculants. When the peristaltic pump transfers fluid, the fluid only flows in the hose. When transferring sewage containing mud and sand, the pumped liquid will not contact the pump, only the pump tube will contact, so there will be no jamming phenomenon, which means The pump can be used continuously for a long time, and the same pump can be used for different fluid transmission by simply replacing the pump tube.
The peristaltic pump has a high fluid transmission accuracy, which can ensure the accuracy of the liquid volume of the added reagent, so that the water quality is effectively treated without adding too much harmful chemical components. In addition, peristaltic pumps are also used for the transmission of tested samples and analytical reagents on various water quality detection and analysis instruments.

As municipal and industrial wastewater treatment becomes more specialized and complicated, precise dosing, chemical delivery and product transfer operations are critical.
Customer application
A water treatment company used Beijing Huiyu fluid peristaltic pump YT600J+YZ35 in the biofilm sewage treatment test process to transfer the sewage containing mud and sand to the biofilm reaction tank to help verify the effectiveness of the biofilm sewage treatment process. feasibility. In order to successfully complete the test, the customer put forward the following requirements for the peristaltic pump:
1. The peristaltic pump can be used to pump sewage with a mud content of 150mg/L without affecting the service life of the pump.
2. Wide range of sewage flow: minimum 80L/hr, maximum 500L/hr, flow can be adjusted according to actual process requirements.
3. The peristaltic pump can be operated outdoors, 24 hours a day, continuous operation for 6 months.
