摘要:
以紫背天葵菜为种植植物,研究植物人工快渗系统对生活污水污染物的去除效果。结果表明,植物人工快渗系统对COD、氨氮和总磷平均去除率分别为85.8%、95.3%和94.8%,COD、氨氮的出水浓度均能满足《城镇污水处理厂污染物排放标准》(GB18918—2002)一级A排放标准。出水中总磷的浓度能满足一级B标准。植物人工快渗系统对总氮平均去除率为67.6%。总氮、总磷较常规人工快渗系统去除率明显提高。植物的吸收和根系的截留是总氮总磷去除率显著增加的主要因素。植物种植为人工快渗系统提供了新的思路,不仅能提高污染物去除效率,还能增加环境美观度。

Abstract:
The efficacy of pollutant removal from a domestic sewage by Begonia fimbristipula plant Constructed Rapid Infiltration system was studied. The results showed that the average removal rates of COD and ammonia nitrogen were 85.8% and 95.3%, respectively and the effluent concentration met Standard I-A of “Discharge standard of pollutants for municipal wastewater treatment plant(GB 18918-2002)”. The average removal rate of total phosphorus was 94.8%, which met Standard I-B of “Discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002)”. The average removal rate of total nitrogen was 67.6%, and the removal rate of total nitrogen and total phosphorus significantly increased compared with those of the conventional constructed rapid infiltration system. Plant absorption is the main factor for increasing the removal rate. Plant cultivation provides a new idea for the constructed rapid infiltration system, which can not only improve the efficiency of the pollutant removal, but also enhance the environmental beauty.
Key words:  constructed rapid infiltration system  plant  COD  TN  TP
