Integrated Air Flotation Wastewater Treatment Equipment

Working Principle Sewage is pretreated by grids and oil separators to intercept large debris and floating oil, then flows into the regulating tank to balance water quality and quantity. A lift pump delivers sewage into the air flotation host. Microbubbles adsorb fine suspended solids, emulsified oil and colloidal impurities to realize rapid solid-liquid separation. The pretreated sewage enters the hydrolytic acidification tank, where anaerobic microorganisms decompose refractory macromolecular organics and reduce pollution load. Afterwards, sewage flows by gravity into the biological contact oxidation tank. Biofilms fully degrade organic pollutants. The mixture then enters the sedimentation tank for solid-liquid separation to remove suspended solids and aged biofilm. Finally, the sewage is sterilized in the disinfection unit and discharged up to standard. Sludge generated by the system is sent to the thickening unit, and the supernatant flows back for recycling. The whole system operates efficiently, energy-saving and reliably. Application Fields Livestock and Poultry Slaughtering Industry: Suitable for slaughterhouses of pigs, cattle, sheep, chickens and ducks. It treats slaughter blood water, depilation cleaning wastewater and meat rinsing wastewater with high oil and high suspended solids, solving the problem of high pollution concentration and hard-to-separate grease in slaughter wastewater. Food & Aquatic Processing Industry: Widely used in cooked food processing, deep meat processing, seafood processing and bean product factories. It effectively treats residue wastewater, oily wastewater and cleaning wastewater generated during production, meeting the treatment requirements of high-organic and high-impurity sewage in food industry. Livestock Breeding Industry: Applicable to large-scale livestock farms, breeding bases and agricultural & pastoral industrial parks. It handles livestock flushing wastewater, manure sewage and comprehensive breeding tail water, degrading organics and removing suspended pollutants to realize compliant discharge of breeding sewage. Light Industry & Daily Chemical Industry: Suitable for small chemical plants, detergent factories, daily chemical processing plants and hardware cleaning workshops. It specially treats production wastewater containing emulsified oil, colloidal impurities and mild chemical pollutants, achieving efficient oil-water separation and water purification. Urban-rural & Factory Comprehensive Sewage: Used for comprehensive sewage of small enterprises in industrial parks, mixed domestic sewage in factory zones, centralized domestic sewage in villages and towns, and oily sewage from small commercial facilities. It fits small and medium-sized sewage treatment projects.
