摘要
本文介绍了以豆制品废水为碳源、硝酸钾为氮源的缺氧生物转盘同时去除废水中的合碳有机物(BOD)和硝酸氮(NO_3-N)的试验研究,探讨了驯化和挂膜条件,取得了在确定BOD_5/NO_3-N比值条件下,去除NO_3-N和BOD_5的最小水力停留时间和最大盘面积负荷工艺参数。
This paper presents an experimental study in which anoxic bio-disc contactor removes carbonaceous organic material (BOD)and nitrate nitrogen (NO3-N) in wastew-ater simultaneously by providing with bean-pi'ocessing wastewater as carbon food and KNO3 as nitrogen food.It makes an insight into the conditions of acclimation and biological filming,obtains some technical design factors such as the minimum hydraulic retention time and the maximum surface area loading rates of removing NO3-N and BOD5 under settling ratio of influent BOD5/NO3-N.
