摘要

人工湿地是去除多种污染物的可行选择。评价了自由流动湿地和地下湿地对生活水中污染物的去除效果。共有12个湿地，其中有物种的湿地3个，没有物种的湿地3个，有物种的湿地3个，没有物种的湿地3个，自由湿地的停留时间为6.7天，地下湿地的停留时间为3.5天。含菌地下出水浊度为4.4±0.8 NTU，色度为143.9±27.4 UC, COD为33.9±25.7 mg -1。含菌种的游离样品浊度为10.1±2.8 NTU，色度为346.3±87.0 UC, COD为74.7±30.0 mg -1。表现最好的是有物种的地下湿地，其浊度、色度和COD去除率分别为95.9%、89.4%和95.7%，COD动力学系数为0.34(自由流)和0.89 days-1(地下)。

Domestic wastewater treated with Sagittaria latifolia in constructed wetlands

Constructed wetlands are viable alternatives for the removal of multiple pollutants. The performance of Sagittaria latifolia in free flowing and subsurface wetlands in removing pollutants from domestic waters was evaluated. 12 wetlands will be followed, three free with species and three without species, three subsurface with species and three without species, with retention times of 6.7 days for the free and 3.5 days for the subsurface. The subsurface with species presented an effluent with turbidity of 4.4±0.8 NTU, color of 143.9±27.4 UC and 33.9±25.7 mgL-1 of COD. The free samples with species presented turbidity of 10.1±2.8 NTU, color of 346.3±87.0 UC and 74.7±30.0 mgL-1 of COD. The wetland with the best performance was the subsurface with species, eliminating turbidity, color, and COD in 95.9, 89.4, 95.7% respectively, obtaining a COD kinetic coefficient of 0.34 (free flow) and 0.89 days-1 (subsurface).
