| 摘 要： | 利用“厌氧生物反应器＋潜流复合型人工湿地”组合工艺处理农村生活污水中氮和磷。厌氧生物反应器和潜流复合型人工湿地水力停留时间分别为24和48h，进水总氮、氨氮和总磷分别为10．3～51．8mg／L、6．8～44．7mg／L和0．9～5．2mg／L，组合工艺对总氮、氨氮和总磷的平均去除效率分别为30．7％、42．9％和72％，不同季节处理效率为：夏季〉春季〉冬季。组合工艺中的COD主要由厌氧水解酸化、基质截留、微生物代谢而被去除，氮主要由人工湿地微生物作用和植物吸收被去除，磷主要由人工湿地基质吸附被去除。系统整体脱氮效果的提高可采用在厌氧生物反应器后增加充氧装置，提高污水中的溶解氧，通过增强人工湿地中的硝化能力来实现。

| Abstract: | Nitrogen and phosphorus removal by Anaerobic bioreactor+Subsurface horizontal-flow compound wetland for rural sewage treating is studied.The total nitrogen varies from 10.3 to 51.8 mg/L,ammonia from 6.8 to 44.7 mg/L,while total phosphorus ranges from 0.9 to 5.2 mg/L in rural domestic wastewater.At anaerobic bioreactor's HRT of 24 h and artificial wetland's HRT of 48 h,the average removal efficiency for TN,ammonia and TP are 30.7%,42.9% and 72.3%,respectively.The treatment performance ranks in a descending o... |
