摘　　要：淀粉生产废水主要包含清洗废水、提取废水、淀粉清洗废水,基于生产废水既有处理方法,以马铃薯淀粉生产废水为例,提出了制成高浓度标准水溶肥产品和可直接使用水溶肥产品2种资源化回用方案,二者都可有效减少生产用水,节约成本,经济效益良好;而制成高浓度标准水溶肥产品可减少大约960 t的COD排放量,可合理利用其中的植物性营养物质有效解决环境污染问题,可基于微量元素保障植物稳定生长;制成可直接使用水溶肥产品可有效解决水环境污染问题,以循环利用水资源与废水蛋白质等珍稀资源,每年可降低960 t的COD排放量,可切实改善土壤,强化土地肥力,二者生态效益均较好。Starch production wastewater mainly includes cleaning wastewater,extraction wastewater,and starch cleaning wastewater.Based on the existing treatment methods of production wastewater,taking potato starch production wastewater as an example,two types of high-concentration standard water-soluble fertilizer products and water-soluble fertilizer products that could be directly used are proposed.The resource recycling scheme,both of which could effectively reduce production water,save costs,and had good economic benefits;and the production of high-concentration standard water-soluble fertilizer products could reduce COD emissions by about 960 tons,and the plant nutrients could be used rationally effectively solve the problem of environmental pollution,and could ensure the stable growth of plants based on trace elements;the production of water-soluble fertilizer products that could be directly used can effectively solve the problem of water environmental pollution,so as to recycle water resources and waste water proteins and other rare resources,which could reduce 960 tons of COD per year.The amount of emissions could effectively improve the soil and strengthen the fertility of the land,both of which had good ecological benefits.
