| 摘 要： | 选取陶瓷碎片废弃物作为基质,芦苇和菖蒲作为湿地植物,构建潜流人工湿地系统,对城市纳污河道内的污染河水进行处理。水力负荷为15cm/d,考察了在较高浓度进水(CODCr和氨氮浓度分别为40~70mg/L和10~35mg/L)和较低浓度进水(CODCr和氨氮浓度分别为15~30mg/L和0.3~3mg/L)2种工况下系统的运行效果。结果表明,在较高浓度进水情况下,系统对CODCr、氨氮的平均去除率分别为10.0%和42.4%;在较低浓度进水情况下,系统对CODCr、氨氮的平均去除率分别为38.5%和63.0%。陶瓷碎片是一种经济有效的湿地基质。 |

| Abstract: | A constructed wetland system was made by selecting potsherd waste as packing medium,reed and calamus as plants to treat polluted river water.With the hydraulic loading of 15 cm/d,pollutants removal performance of the system was studied in the condition of high influent concentration (COD_ Cr and ammonia nitrogen concentration were 40～70 mg/L and 10～35 mg/L,respectively)and low influent concentration (COD_ Cr and ammonia nitrogen concentration were 15～30 mg/L and 0.3～3 mg/L,respectively).The results showed that in the condition of high influent concentration,COD_ Cr and ammonia nitrogen removal rates were 10.0% and 42.4%,respectively,and in the condition of low influent concentration,COD_ Cr and ammonia nitrogen removal rates were 38.5% and 63.0%,respectively.Potsherd waste is a kind of economical and effective packing medium for constructed wetland. |
