Research Status and Progess of Sweetpotato Starch Processing Wastewater Treatment Technology
Sweet potato starch processing wastewater was rich in various substances such as proteins,polysaccharides,fats,and inorganic salts,high concentration of organic matter,low pH value and great difficulty in treatment were the bottleneck of the development of the scale aggregation benefits of sweetpotato starch and its products.In the paper,the processing technolo-gy of sweetpotato starch,the source of processing waste water and the characteristics of water quality were briefly described,and detailed the research and application status of common biotechnology,physicochemical technology,resource recovery technology,and combination technology for treating sweet potato starch processing wastewater.Finally,how to treat sweet potato starch processing wastewater with low consumption and high efficiency was prospected,in order to provide practical theoretical basis for promoting the rapid development of sweetpotato starch and its products industry.
