Study on the optimal technology conditions about decomposing of the protein in the dairy wastewater

JIN Jie,LIU Bin,YU Zhi_min(Department of Biological and Environmental Engineering,Hefei University,Hefei 230022,Anhui,China)  
Tests on protein decomposing proteinase activity and COD of dairy wastewater were studied to search for some key influencing parameters under the anaerobic fermentation such as temperature,pH,ratio of sludge to wastewater and time.According to single factor,the direct cross_experimentation with four factors and three levels was designed.Through analysis of extreme difference,the optimal technology condition was as follews temperature 30℃,pH7.0,time of fermentation 4days and ratio of sludge to wastewater 1/11.5 respectively.
