马铃薯淀粉生产废水再循环利用研究

Study on the Recycling of Potato Starch Production Wastewater

通过对宁夏南部山区马铃薯淀粉加工企业现状的调查和对西吉马铃薯淀粉工业用水的分析,结合当地干旱少雨的自然条件,提出采用多效蒸发的技术。将绝大部分生产废水经蒸发、冷凝后,作为生产用水循环利用,并将蛋白和有机肥从回收工艺中加以提取分离和浓缩。从根本上解决废水污染和水资源综合利用的问题。

Based on investigating the processing enterprise actuality of potato starch in south-mountain area of Ningxia and analyzing the industrial water in potato starch in Xiji County, combined with the drought and rainless natural conditions in the local areas, the technology of multi-effect evaporation was bring forward. By using this method, a majority of wastewater was vaporized, condensed, and recycled for being taken as the production water. And albumen and organic fertilizer was separated and contracted in the recycling process. The problem of wastewater pollution and the comprehensive utilization of water resources were radically resolved.
