| 摘 要： | 为探索经济可行的海水养殖废水处理技术,选取南美白对虾海水养殖废水,对比研究了多介质土壤滤层(multi-soillayer,MSL)系统和4种不同植物配置潜流式人工湿地(大米草型、芦苇型、香蒲型和无植物型)在400 L·(m2·d)-1水力负荷下的废水处理效果.结果表明,MSL对化学需氧量(COD)、总磷(TP)、总氮(TN)、氨氮(NH+4-N)和硝态氮(NO-3-N)的平均去除率分别为80.38%±2.14%、68.14%±3.51%、40.79%±3.10%、42.68%±2.90%和54.19%±5.15%,均高于其他4种不同植物配置的潜流式人工湿地的处理效果.4种人工湿地系统对各污染物的去除率从高到低依次为:大米草型>芦苇型>香蒲型>无植物型.

| Abstract: | To evaluate the feasibility of using multi-soil-layer (MSL) system and subsurface flow constructed wetland to treat the wastewater of marine cultured Penaeus vannamei and to determine the suitable process for the local aquaculture wastewater pollution characteristics. In this study, MSL system and four constructed wetland systems with Spartina anglica, Phragmites australis, Typha latifolia and unplanted system were evaluated for their potentials of pollutants removal capacity. The results showed the average removal rates of chemical oxygen demand (COD), total phosphorus (TP), total nitrogen (TN), ammonia nitrogen (NH4+-N) and nitrate (NO3--N) by MSL system were 80.38%±2.14%, 68.14%±3.51%, 40.79%±3.10%, 42.68%±2.90% and 54.19%±5.15%, respectively. Additionally, the ability of pollutants removal of other four wetland systems decreased in the order: Spartina anglica, Phragmites australis, Typha latifolia and unplanted system. |
