| 摘 要： | 通过水平潜流人工湿地处理精养虾塘排水的中试试验,探讨了在不同高水力负荷条件下1.10～5.34 m3.(m2.d)-1]人工湿地对有机物、氮磷以及悬浮物的去除效果,以期为其设计运行提供参考.结果表明,水力负荷与COD、TN、TP、SS的去除率呈负相关;COD、TN、SS去除速率随水力负荷的升高,先升后降,最高分别达到69、1.8和117.6 g.(m2.d)-1;TP的去除速率随水力负荷的升高变化并不明显.人工湿地在水力负荷2.52～3.24 m3.(m2.d)-1范围内运行时,污染物去除总量最高处理效果最佳.

| Abstract: | A pilot scale experiment of intensive shrimp aquaculture wastewater treatment using horizontal subsurface flow constructed wetland is carried out and the effect of treatment performance under high hydraulic loading conditions 1.10-5.34m3·(m2·d)-1] is investigated. The results show that, hydraulic loading and reduction efficiency of COD, TN, TP and SS is negatively correlated. However, with the hydraulic load increases, the removal rate of CODup to 69g·(m2·d)-1], TNup to 1.8 g·(m2·d)-1] and SSup to 117.6 g·(m2·d)-1] first increased and then decreased, while the change of TP removal rate is not obvious. Therefore, under the range of 2.52 m3·(m2·d)-1 to 3.24 m3·(m2·d)-1 high hydraulic loading, constructed wetland shows best technically feasible for managing wastewater treatment of intensive aquaculture. |
