摘要
2019年4~7月采用模拟人工湿地种植水葱(Scirpus validus Vahl)和香蒲(Typha orientalis Presl),研究水葱与香蒲对微咸水中N、P、Pb和Cd的去除率。通过与进水浓度的比较(去除率1)可知,香蒲湿地、水葱湿地和无植物栽培的CK湿地对N、P和Pb、Cd均有较好的去除。香蒲湿地在第1周期(4月)对Pb和Cd的去除率分别为97.7%和52.7%;水葱湿地在第2周期(5月)对TN和TP的去除率分别为95.3%和85.3%。通过与无栽培植物的CK比较(去除率2)可知,水葱在第1周期(4月)对TN的去除率达66.7%,在第2周期(5月)对TP的去除率达60.7%。香蒲在第1周期(4月)对Pb的去除率达65.0%,对Cd的去除率达52.7%。
The removal rate of TN,TP,Pb and Cd in brackish water by Scirpus validus Vahl and Typha orientalis Presl,which were planted in the simulated constructed wetland,was studied from April to July in 2019.Comparing with the influent concentration(removal rate 1),there was a good removal result for N,P,Pb and Cd in the Typha orientalis Presl wetland and the Scirpus validus Vahl wetland as well as the CK wetland without plants.In the first cycle(April),the removal rates of Pb and Cd in Typha orientalis Presl wetland were 97.7% and 52.7%,respectively.The removal rates of TN and TP in Scirpus validus Vahl wetland were 95.3% and 85.3% in the second cycle(May).Comparing with the CK effluent concentration(removal rate 2),the TN removal rate was 66.7% in the first cycle(April)and TP was 60.7% in the second cycle(May)by the Scirpus validus Vahl.And the removal rates of Pb and Cd were 65.0% and 52.7% in the first cycle(April)by the Typha orientalis Presl.
