AI Technical Summary
Existing technologies are insufficient to effectively treat wastewater from the bottom of liquor cellars, leading to environmental pollution and resource waste, and failing to achieve green and sustainable development of the liquor industry.
The method employs photocatalytic treatment combined with Bacillus amyloliquefaciens and lactic acid bacteria fermentation. First, the photocatalyst removes recalcitrant organic matter and toxic substances. Then, the pH is adjusted and Bacillus amyloliquefaciens and lactic acid bacteria are added to ferment and produce valuable substances such as lactic acid.
This method enables the efficient resource utilization of wastewater from the bottom of liquor cellars, reduces COD levels, generates economically viable lactic acid products, and produces no secondary pollution, thus supporting the green development of the liquor industry.
