Modularized integration method for treating soy sauce brewing wastewater

Abstract

The present invention relates to the field of integrated treatment of high concentration organic wastewater, and in particular relates to a modularized integration method for treating soy sauce brewing wastewater. Aiming at the problem of treatment of high concentration organic wastewater generated in the production process of soy sauce brewing enterprises, the method comprises process integration and parametric design, and uses a first pre-processing module, a secondary biochemical module and a third deep processing module, the first pre-processing module is used to remove suspended solids and regulate the homogeneous function, the secondary biochemical module is provided with an anaerobic submodule (anaerobic expansion bed / anaerobic fluidized bed) and an aerobic submodule (semi-intermittent biological turntable, intermittent membrane bioreactor) which are in series connected, the third deep processing module is provided with a mixed flocculation sedimentation tank, an activated carbon adsorption pool and an ultraviolet disinfection sub-module which are in series connected. According to influent water quality conditions, running module and control module operating parameters are selected. The method has the characteristics of flexibility, high efficiency, convenience and intelligence, and the like, and can guarantee the economical, effective and stable operation of wastewater treatment facilities.

Description

technical field [0001] The invention relates to an integrated treatment technology for high-concentration organic wastewater, in particular to a modular integrated method suitable for the treatment of soy sauce brewing wastewater. Background technique [0002] At present, my country's soy sauce production is mainly based on the "low-salt solid-state process" in the north and the "high-salt dilute process" in the south. The general soy sauce production process includes raw material processing, koji making, fermentation, leaching and oil pouring, and heating preparation. Soy sauce wastewater is a food fermentation wastewater with high organic content, and its components are mainly food residues (such as: crushed beans) crumbs, bran, flour, sugar, soy sauce, fermentation residue, various microorganisms and enzymes and metabolites secreted by microorganisms, soy sauce pigment, trace detergent, disinfectant and a small amount of salt, etc.), the color is high, and the composition...
