哈尔滨市9种湿地植物在不同HRT下净污效果研究
Study on the Pollutant Removal Efficiency of Nine Wetland Plants in Harbin
摘要
Abstract
A total of nine wetland plants including Sagittaria trifolia Linn,Scirpus validus Vahl,Typha orientalis Presl,Deyeuxia angustifolia Y.L.Chang,Acorus calamus Linn,Alisma plantagoaquatica Linn,Phragmites australis,Sanguisorba officinalis Linn and Juncellus serotinus were selected to construct a small-scale man-made wetland in Harbin.The pollutant removal ability of these wetland plants were analyzed under different hydraulic retention time.Results showed that the optimal hydraulic retention time was 5d,and the average removal rate of TN,TP,COD among the wetland plants was 81.80%,77.51%,and 55.25%,higher than that of the control groups.The removal capacity of TP were ordered as follows:Typha orientalisDeyeuxia angustifoliaSagittaria trifoliaScirpus validusAcorus calamusJuncellus serotinusAlisma plantagoaquaticaSanguisorba officinalisPhragmites australis.The order of the removal capacity of TN was:Typha orientalisSagittaria trifoliaAcorus calamusDeyeuxia angustifoliaJuncellus serotinusScirpus validusAlisma plantagoaquaticSanguisorba officinalisPhragmites australis.The order of the removal capacity of COD was:Typha orientalisAcorus calamusJuncellus serotinusScirpus validuSagittaria trifoliaDeyeuxia angustifoliaAlisma plantagoaquaticaSanguisorba officinalisPhragmites australis.These results indicated that Typha orientalis、Scirpus validus、Sagittaria trifolia were the best wetland plants with higher removal ability,which could be used in constructed wetlands.关键词
