Three major sewage treatment methods of air flotation machine
An air flotation machine uses various technical methods to separate and remove pollutants from wastewater, recycle and reuse them, or convert them into harmless substances to purify the water. The air flotation machine sewage treatment technology can be divided into three categories according to principles: physical treatment method, chemical treatment method, and biological treatment method. 1. Physical treatment method: using physical actions to separate suspended solid pollutants in wastewater. The methods include screening, sedimentation, float flotation, air flotation, filtration, and reverse osmosis. 2. Chemical treatment method: using the action of chemical reactions to separate and recover pollutants in various forms (including suspended, dissolved, colloidal, etc.) from wastewater. The main methods include neutralization, coagulation, electrolysis, oxidation-reduction, stripping, extraction, adsorption, ion exchange, and electrodialysis. 3. Biochemical treatment method: utilizing microbial metabolism to convert dissolved and colloidal organic pollutants in wastewater into stable and harmless substances. The main methods can be divided into two categories, namely aerobic methods using aerobic microorganisms (aerobic oxidation method) and anaerobic methods using anaerobic microorganisms (anaerobic reduction method). The former is widely used for treating urban sewage and organic production sewage, including two methods: activated sludge process and biofilm process; The latter is mostly used to treat high concentration organic wastewater and sludge generated during wastewater treatment processes, and is now also being used to treat urban wastewater and low concentration organic wastewater.
