摘要:
为推动马铃薯淀粉行业科学、精准治理加工废水，针对其加工废水高有机质、高氮、高磷的水质特性，在宁夏固原某马铃薯淀粉加工企业采用工艺废水（汁水）蛋白回收与综合废水土地利用联合处理工艺（处理规模以工艺废水计，30 m3/h）替代传统末端生化处理工艺，并进行环境效益、经济效益及社会效益分析。生产运行数据表明，该联合处理工艺的蛋白回收率达到40.93%，SS去除率达到54.76%，COD去除率为19.2%，综合废水全部实现土地利用，基本实现工艺设计目标。示范工程的联合处理工艺相比废水达标排放，每年减排COD、SS、总氮、总磷分别为 6.64 t、1.99 t、1.99 t、66.4 kg，并可为企业增加经济效益（税后61万元/a）。此外，还可以增加当地农民收入，实现资源循环利用。该联合处理模式将传统末端污染治理投入模式转变为资源利用产出模式，较好地解决了企业水污染治理问题，同时经济效益、社会效益显著，为马铃薯淀粉行业废水治理提供了新路径。
Abstract:
In order to promote the scientific and precise treatment of processing wastewater in the potato starch industry, based on its characteristics of high organic matter, high nitrogen and high phosphorus, a combined treatment process of protein recovery from processing wastewater and comprehensive wastewater land use with treatment scale of 30 m3/h process wastewater is adopted in a potato starch processing enterprises in Ningxia Guyuan to replace the traditional end biochemical treatment process of wastewater, and to analyze the environmental benefits, economic benefits and social benefits. The production and operation data show that the protein recovery rate, SS removal rate and COD removal rate of the combined treatment process were 40.93%, 54.76% and 19.2%, respectively. All the comprehensive wastewater was successfully returned to the field for utilization, indicating that the goal of designed process was generally achieved. The benefit analysis shows that the combined treatment process of the demonstration project can reduce the annual discharge COD, SS, total nitrogen, and total phosphorus by 6.64 t, 1.99 t, 1.99 t and 66.4 kg, respectively, compared with up-to-standard discharge of wastewater, and could increase the economic benefit of 610 thousand yuan after tax for the enterprise every year. In addition, it could increase the income of local farmers and realize the recycling of resources. The combined treatment model transforms the traditional end pollution input mode into resource utilization output mode, which better solves the problem of enterprise pollution control, and has significant economic and social benefits. It provides a new path for wastewater treatment in the potato starch industry.
