Abstract Nitrogen dynamics were studied over 3 years in pilot-scale surface flow constructed wetlands (SFCWs) treating three strengths of ammonium-rich swine wastewater. A high removal rate of ammonium (1.2–2.9 g m−2 d−1) and total nitrogen (1.5–3.5 g m−2 d−1) was achieved from highstrength wastewater in the SFCWs. Nitrate concentration was significantly higher (p

低温会增加具有高脱氮率的中试规模地表流人工湿地中的硝酸盐积累

摘要 在中试规模的地表流人工湿地 (SFCW) 处理三种富含铵的猪废水时,对氮动力学进行了 3 年多的研究。从 SFCW 中的高强度废水中实现了铵 (1.2-2.9 gm-2 d-1) 和总氮 (1.5-3.5 gm-2 d-1) 的高去除率。硝酸盐浓度显着更高(p
