Article Preview

This article mainly studies the effect of pretreatment in high temperature on reducing sugar content in cow dung waste water in different conditions. Based on the single-factor research, this experiment chooses three factors-temperature, pH value and pretreatment time as independent variable, reducing sugar content as response variable to conduct the response surface experiment, adopts Box—Behenken method to carry out experimental design in order to study the effect of each variable and their interaction on reducing sugar content in waste water. Through the experiment and fitting analysis, the second degree polynomial regressive equation model is retained, and the best pretreatment condition is calculated as this: pretreatment time is 5 days, pH value at 5.9 and temperature at 49°C. Finally the experiment shows that the maximum reducing sugar content in cow dung under this condition is 1.2789 mg/mL.
