In recent years, with the rapid development of the social economy, sewage treatment has increasingly become an indispensable part of economic development and water resources protection. The Peristaltic Pump also played a large role in this process. Please follow me to understand the application of peristaltic pumps in sewage treatment. Overview of Sewage treatment: Sewage treatment is to make sewage discharge into a water body or reuse the water quality requirements for its purification process. Modern sewage treatment technology, according to the degree of treatment is divided into primary, secondary, and tertiary treatment. Primary treatment, mainly to remove suspended solid substances in sewage, commonly used physical method. After primary treatment of sewage, BOD can generally remove about 30%, cannot meet the discharge standard, primary treatment belongs to the pretreatment of secondary treatment. Secondary treatment, mainly to substantially remove colloidal and dissolved organic matter (BOD, COD material) in sewage. Generally, reaching the secondary treatment of sewage can meet the discharge standard, commonly used activated sludge method, and biofilm treatment method. Tertiary treatment, further removal of some special pollutants, such as phosphorus, nitrogen, and biodegradable organic pollutants, inorganic pollutants, pathogens, and so on. The main methods include biological denitrification and phosphorus removal, coagulation precipitation, sand filtration, activated carbon adsorption, ion exchange, and electroosmosis analysis. Working principle of peristaltic pump: The peristaltic pump is a kind of precision transmission equipment, which is assembled by the actuator, Peristaltic Pump Head, and peristaltic pump silica gel tube. It transmits liquid by squeezing the silica gel tube with the pump roller. Its transmission precision and hygiene are widely used in the sewage treatment and pharmaceutical industry. Sewage treatment needs: In the process of water treatment in the factory, to ensure the quality of drinking water, primary disinfection, secondary disinfection, and pH control need to carry out accurate quantitative feeding, in these processes need to use a good sealing pump. Ferric chloride, sodium hypochlorite, chlorine, carbon, lime, and other chemicals often cause gear wear and pump blockage, resulting in the performance of the pump decline, reduced life, especially lime and polymer electrolyte will cause serious impact on the operation of the pump, usually only to replace the new pump. At the same time, the performance of shear-sensitive flocculants is greatly reduced when they pass through high flow rates and tortuous pump channels. As a result, safe, accurate, and efficient chemical dosing and delivery is the goal of every wastewater treatment operation, the industry urgently needs a pump that can be used to treat harsh applications to optimize the production process, reduce maintenance work while reducing costs and improve treatment efficiency. The above requirements are the advantages of a peristaltic pump. Application in sewage treatment: As municipal and industrial wastewater treatment becomes more specialized and complex, precise dispensing, chemical transport and product transfer operations are critical. In sewage treatment plants, in sodium hypochlorite feeding system, when the concentration of sodium hypochlorite should be diluted to 1%, it is easy to cause salt solidification in the pipeline and storage tank. Because the accumulation of gas in the system can cause various hazards and easily lead to gas handling problems, in this case, a pump that is not affected by gas handling, crystallization, has good chemical resistance and does not accumulate in the pump head. And peristaltic pump because of its characteristics, in this process can be easily competent.
