摘要

摘要: 将给水厂副产品——铝污泥作为人工湿地的填料,采用A/O+铝污泥填料人工湿地组合工艺对农村生活污水进行处理。结果表明,组合工艺对化学需氧量(COD_Cr)、氨氮(NH₃-N)、总氮(TN)、总磷(TP)的总平均去除率分别为82.33%、81.58%、76.22%和86.50%,出水水质满足GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准;组合工艺的铝污泥填料湿地段对TP的去除率为50.43%,显著高于传统湿地,铝污泥填料的吸附作用是其去除磷的主要途径;A/O+铝污泥填料人工湿地组合工艺能有效提高脱氮与除磷效率,实现污水的深度处理,又能缓解湿地堵塞,延长人工湿地的使用寿命。

Abstract: The aluminum sludge, a by-product of the water supply plant, was used as the filler of the constructed wetland, and A/O+ aluminum sludge filled artificial wetland combination process was adopted to treat the rural domestic sewage. The results showed that the total average removal rates of chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus were 82.33%, 81.58%, 76.22% and 86.50%, respectively, and the effluent quality could reach Level 1A standards of Pollutant Discharge Standard of Urban Sewage Treatment (GB 18918-2002). The removal rate of TP was 50.43% in aluminum sludge filled constructed wetland, significantly higher than that of traditional wetlands. The adsorption of aluminum sludge filler was the main way to remove phosphorus. The combination process of A/O + aluminum sludge filled constructed wetland could effectively improve the efficiency of nitrogen and phosphorus removal, realize the deep treatment of sewage, alleviate the blocking of wetlands, and extend the service life of constructed wetlands.
