Abstract
Soybean wastewater is a kind of nutrients wastewater. Using yeast to treat this kind of wastewater can not only degrade high concentration organic pollutants, but the yeast cell itself also can be harvest and realize the resources recycling. In this work, the feasibility and the optimal conditions of using yeast to treat soybean wastewater were investigated. Results showed that the initial COD and hydraulic retention time were the critical factors influencing COD degradation. Under 28 °C and with the initial soybean wastewater of 4800 mg/L, usingCandida utiliswith 20% of inoculums dosage could realize the higher reduction of the concentration of COD. And after 18 h’s treatment with rotating speed of 160 rpm, the COD removal could reach to 90%. The yeast wastewater treatment technology has the prospect of resources recycling. Besides, the pH value is very important for yeast to treat soybean wastewater.
