Comparative Study on the Anaerobically Methanogenic Results of Sauce Sweet Model Liquor and Fen-Flavor Liquor Wastewater

Abstract:

Based on the condition test and comparative analysis of mixing bottom pot water and bottom cellar water from a sauce sweet model liquor enterprise and a fen-flavor liquor enterprise, this study discuss the difference of recycling methane from anaerobic fermentation in two types of distilled spirit wastewater. The results of the tests show mixing the bottom pot water and bottom cellar water of the two kinds of Chinese spirits under the optimal proportion and conducting the anaerobic experiment under optimum conditions, the COD concentrations in effluent of both mixed distilled spirit wastewater are approximately the same. And the rates of degradation in two types of wastewater are almost the same. At the same time, the gas production of sauce sweet model liquor wastewater is a little higher than that of fen-flavor wastewater. The best removal rates of COD are 90.22% and 88.99% respectively for the two types of wastewaters.
