Brewing wastewater treatment is usually to deal with high-concentration organic wastewater. Soy sauce wastewater is a kind of food fermentation wastewater with high organic content. The ingredients are mainly food residues such as crushed bean crumbs, bran, flour, sugar, soy sauce, fermentation residue, various Microorganisms and enzymes and metabolites secreted by microorganisms, soy sauce pigments, trace detergents, disinfectants and a small amount of salt, etc., with high color, wastewater treatment is difficult, brewing wastewater treatment is widely used in wine, liquor, beer, soy sauce And other fields.
The anaerobic treatment process of brewing wastewater is as follows:
Brewing wastewater treatment process description
1. After the brewing wastewater is treated by the pretreatment facilities such as the original sedimentation tank, the existing first-level anaerobic tank is transformed into a hydrolytic acidification tank, the effluent enters the distribution well, and the distribution well is transformed by using the first-level oxidation tank. And set up a heating system in the water distribution well to maintain the water temperature of the wastewater at 35 ± 3 ℃ to ensure the smooth operation of the subsequent anaerobic process.
2. Use the original N and P nutrient addition device in the water distribution well to supplement the lack of nutrients in the wastewater and maintain a high removal effect;
3. The effluent from the distribution well is pumped to the LXIC anaerobic reactor, where most of the organic matter is removed by the decomposition of anaerobic microorganisms in the LXIC anaerobic reactor, and a large amount of clean energy-biogas and can be sold as strain High-quality granular sludge;
4. IC effluent enters subsequent structures for treatment and discharges after reaching discharge standards.
