Anaerobic reactor for vinasse wastewater treatment

Abstract

The invention discloses an anaerobic reactor for vinasse wastewater treatment, and belongs to the field of anaerobic reactors, according to the scheme, wastewater is discharged into an anaerobic reactor body after being filtered through a water inlet pipe and a filter screen frame, anaerobic microorganisms in the anaerobic reactor body adsorb and decompose the wastewater, water-soluble balloons are dissolved in water, exposed reducing iron powder reacts with oxygen in water to generate ferroferric oxide, so that the iron element in the ferroferric oxide promotes the reaction of anaerobic microorganisms, shortens the anaerobic digestion reaction time, improves the decomposition rate of wastewater, increases the heat release, provides a good temperature environment for the growth and reaction of the anaerobic microorganisms, further improves the digestion reaction efficiency; and the wastewater flows to drive flowing blades to rotate, so that a rotating cylinder is driven to rotate through a first transmission wheel, a second transmission wheel and a transmission belt, and a memory stirring rod which is heated to bloom is driven to rotate and stir, so that the wastewater and anaerobic microorganisms are mixed and contacted more sufficiently, and the reaction effect is enhanced.

Description

technical field [0001] The invention relates to the field of anaerobic reactors, in particular to an anaerobic reactor for wine tank wastewater treatment. Background technique [0002] Brewing wastewater is a kind of low-nutrient wastewater with a C / P ratio of 250. If the traditional activated sludge method is used for treatment, the problems of sludge bulking and high effluent COD are prone to occur. However, activated sludge rich in polysaccharide bacteria is used The sludge system treats brewery wastewater. Without adding nutrients, the effluent water quality is good and no sludge bulking occurs. By adjusting the operating parameters, the COD removal rate can reach up to 97%, and the effluent COD is as low as 15.31mg / L, so the brewery generally conducts anaerobic treatment of brewing wastewater through an anaerobic reactor. [0003] In the prior art, during the working process of the anaerobic reactor, the adsorption and decomposition of the wastewater by the anaerobic ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, during the working process of the anaerobic reactor, the adsorption and decomposition of the wastewater by the anaerobic microorganisms inside the reactor is not sufficient and comprehensive, which makes the wastewater treatment efficiency slower, consumes a lot of processing time, and increases the cost of use.
