| 中文摘要 |
| 在进水COD浓度400 mg/L-800 mg/L,温度15℃-23℃时,人工湿地装置处理乳制品加工废水的COD去除率达97%-98%,面积负荷率达23.3 g/(m2·d)-28.2 g/(m2·d),BOD5的去除率达97%-99%,BOD5的面积负荷率为12.6 g/(m2·d)-17.2 g/(m2·d),几乎70%-90%COD和BOD5去除率发生在进水沟段,如果没有pH冲击贡荷,处理装置的出水水质会稳定地保持在很高的水平。 |
| 英文摘要 |
| Under the influent COD concentration between 400-800 mg/L and temperature between 15-23℃, the constructed wetland functioned efficiently for COD removal. COD mass removal efficiencies reached 97 to 98%, and total removal rates reached 23.3 to 28.2 g/m2·d. BOD5 mass removal efficiencies reached 97 to 99%, while total removal rates reached 12.6 to17.2 g/m2·d. The influent trench played an important role in COD and BOD5 removal. Nearly 70 to 90% of the COD and BOD5 removal occurred in the influent trench. During the entire experimental period, the reed bed effluent water quality met secondary discharge standards if there was no pH shock loading. |
