【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 effect of plant artificial rapid osmotic system on the removal of pollutants from domestic sewage was studied. The results showed that the plant artificial rapid osmotic system was effective on COD. The average removal rates of ammonia nitrogen and total phosphorus were 85.8% and 94.8% respectively. The effluent concentration of ammonia nitrogen can meet the pollutant discharge standard of municipal wastewater treatment plant (GB18918-2002). The concentration of total phosphorus in effluent can meet the first class B standard. The average removal rate of total nitrogen in plant artificial rapid osmotic system is 67.6%. The removal rate of total phosphorus was significantly higher than that of conventional artificial rapid osmotic system. The absorption of plants and the interception of root system were the main factors to increase the removal rate of total nitrogen and phosphorus significantly. Plant planting provided a new way of thinking for artificial rapid osmotic system. It can not only improve the removal efficiency of pollutants, but also increase the environmental aesthetics.

【正文快照】： 人工快渗系统是在土地处理基础上演变的污水处理技术[1],人工快渗系统对有机污染物、氨氮、SS、阴离子表面活性剂等常规的污染物去除率较高,但是对总氮、总磷的去除率偏低,不能满足相关排放标准的要求[2-5]。一些学者通过添加特殊渗滤介质以及外加碳源等方法提高了系统的脱氮
