基于15N质量平衡法研究养殖消化废水中氨氮的去除机理OACSCDCSTPCD
Mechanisms of ammonium removal from digested piggery wastewater by Oedogonium sp .assessed via isotope mass balance analysis
为避免养猪场消化废水对环境造成的污染,利用微藻去除消化废水中营养物质的二次处理方法受到了广泛关注.采用15 N质量平衡法研究了鞘藻去除氨氮的主要机理,重点研究了鞘藻生长与氨氮去除的关系以及氨氮去除的主要途径.经高压灭菌后的消化废水在鞘藻培养期的氨氮去除率为96.2％,鞘藻特定生长率为0.04～0.15;稀释后的原消化废水氨氮的去除率为94.1％,鞘藻特定生长率为-0.14～0.13.通过曝气的汽提效应对氨的去除有显著的促进作用,尤其在高pH值试验…查看全部>>
Nutrient removal from digested piggery wastewater (DPW)using microalgae is of increasing interest as a secondary treatment prior to discharge to avoid environmental contamination.In this study, we investigated the main mechanisms involved in ammonium removal from DPW by Oedogoniumsp.using the15 N mass balance approach with a focus on the relationship between algal growth and ammonium removal and the dominant ammonium removal pathway.We noted 96.2％ ammonium r…查看全部>>
