摘要
为了选择适合在中国四川地区生长的湿地植物．作者在四川省成都市１９９３年１０月２日～１１月１９日的深秋季节进行了湿地系统处理模拟污水的盆栽静态试验，以研究多种湿地植物在自然环境条件下对污染物的去除情况。试验发现：灯蕊草、芦苇、菖蒲这三种植物在１４天内均能去除模拟水样中的ＣＯＤ＿ｃｒ，其中，芦苇的去除率为３８％，菖蒲的去除率为４１％，灯蕊草的去除率为４２～４６％。这三种植物同时也能将污水的ｐＨ值从３．５调节到中性（７．０）。试验表明，用灯蕊草作为湿地植物的条件优于其它两种植物。而且在四川省，灯蕊草又是一种经济作物．具有一定市场前景，因此，在川地区应用人工湿地系统技术处理污水时，选择灯蕊草作为湿地植物是适宜的。
To select plants adaptable for waslewater tuealment by wetland system in Sichuan,experimental observation in potsfilled with still simulated wastewater and gravels under natural conditions in late autumn has been proceeded in Chengdu. Results ob-tained indicates that three species of plant:Juncus effcus, phragmites communis and Acorus calamus calamus can all reduce CODcr of simu-lated wastewater.The COD removal rates by these plants werc 38% for Phragmites communis, 41% for Acorus calamus,42% and46 % for Juncus effucus in 14 days. These plants These plants can also regulate pH values of wastewater from 3.5 to neutrality during 14 daygrowth. In this study, performance of Juncus effucus was better that of the others .In addition,since Juncus effucus is popular in Sichuan with economic value in market ,it was selected in the study as an adaptable plant for wastewat for wastewatcr treatment by wetland sys-tem in Sichuan
