Bean product wastewater treatment UASB anaerobic reactor manufacturer

UASB anaerobic reactor food processing wastewater treatment equipmentsummary:

The pollutants in food processing wastewater mainly include vegetable leaves, fruit peels, minced meat, oils, proteins, pathogenic bacteria and other impurities. In order to effectively remove impurities from the wastewater, the food processing wastewater treatment equipment adopts biological treatment technology to treat the raw water, and the effluent quality meets the standard for wastewater reuse. Food processing wastewater treatment equipment is widely used in industry wastewater treatment.

UASB anaerobic reactor food processing wastewater treatment equipmentThe wastewater is introduced as evenly as possible into the bottom of the reactor, and the sewage flows upward through a sludge bed containing granular sludge or flocculent sludge. Anaerobic reactions occur during the process of contact between wastewater and sludge particles. The biogas produced under anaerobic conditions (mainly methane and carbon dioxide) causes internal circulation, which is beneficial for the formation and maintenance of granular sludge. Some gases formed in the sludge layer adhere to the sludge particles, and the attached and unattached gases rise towards the top of the reactor. The sludge rising to the surface collides with the bottom of the gas emitter in the three-phase reactor, causing the sludge flocs with attached bubbles to degas. After the release of bubbles, the sludge particles will settle on the surface of the sludge bed, and the attached and unattached gases will be collected in the gas collection chamber of the three-phase separator at the top of the reactor. The function of the baffle placed under the gap of the gas collection chamber unit is to act as a gas emitter and prevent biogas bubbles from entering the sedimentation zone, otherwise it will cause flocculation in the sedimentation zone and hinder particle sedimentation. The liquid containing some remaining solids and sludge particles enters the sedimentation zone through the separator gap.

Due to the increased flow area of the inclined sedimentation zone of the separator near the water surface, the upward flow velocity decreases near the discharge point. Due to the decrease in flow rate, sludge flocs can coagulate and settle in the sedimentation zone. The accumulated sludge flocs on the three-phase separator will to some extent exceed the frictional force it maintains on the inclined wall, and it will slide back to the reaction zone, where this part of the sludge will react with the incoming organic matter.
