Resource Utilization Situation and Application Prospect of Starch Wastewater

Starch wastewater contains a lot of starch, protein, sugar, fat and other substances of economic value, and it is not only wastes resources, but increases treatment cost when the wastewater is direct treated by anaerobic-aerobic system, so it is necessary to propel the resource utilization of starch wastewater. Based on a large number of references both at home and abroad, the resource utilization situation of starch wastewater and main technical methods was expounded and the technical characteristics of four methods were summarized, including using starch wastewater to develop ecological agriculture, recycle useful components, cultivate functional microorganism and produce new energy. Then the effect of resource utilization on the treatment of starch wastewater was analyzed and the development direction of starch wastewater resource utilization was put forward.
