| 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 COD[up to 69g·(m2·d)-1], TN[up to 1.8 g·(m2·d)-1] and SS[up 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. |
