摘要

采用以回收塑料为填料的厌氧滤池与人工湿地这一组合工艺对农村生活污水进行处理,研究其性能特点和脱氮除磷效果。结果表明:在厌氧滤池水力停留时间(HRT)为6 h,人工湿地水力负荷为0.12 m3/(m2·d),气水比(体积比)为6∶1条件下,该组合工艺对COD、氨氮、TN和TP的平均去除率分别为84.99%、69.31%、65.11%、73.58%,平均出水质量浓度分别为20.44、6.82、12.53、1.00 mg/L,均满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准,其中COD和TN平均出水浓度还满足一级A标准。
        The combined process of recycled plastics anaerobic filter and constructed wetland for the treatment of rural sewage was used to study the performance characteristics and the effect of nitrogen and phosphorus removal. The operating parameters were set as hydraulic retention time( HRT) of 6 h in the anaerobic filter,hydraulic load of 0.12 m3/( m2·d) in the constructed wetland and air-water ratio( volume ratio) of 6 ∶ 1. Under these operation conditions,the average removal efficiencies of COD,ammonia nitrogen,TN and TP were 84.99%,69.31%,65.11% and 73.58%,and their average concentrations in effluent were 20.44,6.82,12.53 and 1.00 mg/L,respectively,meeting the 1 B standard of"Discharge standard of pollutants for municipal wastewater treatment plant"( GB 18918-2002),while COD and TN also met the 1 A standard.
