摘要:
针对传统人工湿地脱氮效率低及农村地区用电不便问题，构建了以麦饭石-活性氧化铝球（体积比为10∶1）为除磷基质、CaO2基缓释氧材料（释氧周期约125 d）为核心的无动力增氧型人工湿地系统。在进水COD、TP、NH4+-N、TN浓度分别为（180.24±3.59）、（2.88±0.11）、（25.85±0.48）、（34.02±1.29） mg/L条件下，去除率分别为（89.65±1.89）%、（77.68±2.46）%、（79.44±0.63）%、（64.35±2.23）%，出水水质稳定达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级B标准。运行成本分析显示，首年建设及运行费约3.55万元，为分散式农村污水高效脱氮除磷及低成本运行提供了可行方案。
Abstract:
To address the challenges of low nitrogen removal efficiency in conventional constructed wetlands (CWs) and limited access to reliable electricity in rural areas, a novel passive aeration constructed wetland system was developed. This system features maifanite and activated alumina balls (10∶1) as the phosphorus removal substrate and CaO2?based slow-release oxygen materials (with an oxygen release period of approximately 125 days) as its core component. Under the influent conditions with COD of (180.24±3.59) mg/L, TP of (2.88±0.11) mg/L, NH4+-N of (25.85±0.48) mg/L, and TN of (34.02±1.29) mg/L, the system achieved removal efficiencies of (89.65±1.89)%, (77.68±2.46)%, (79.44±0.63)% and (64.35±2.23)% for COD, TP, NH4+-N and TN, respectively. The effluent quality consistently met the first level B standard specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Cost analysis revealed a first-year construction and operation cost of approximately CNY 35 500. This study provides a practical and economically viable alternative for efficient nitrogen and phosphorus removal in decentralized rural domestic sewage treatment systems.
