人工湿地技术在污水净化中的应用研究

研究人工湿地技术在污水净化中的去除机理,分别对人工湿地技术对污水中的悬浮物、有机物、脱氮、除磷和重金属去除机理进行了分析和阐述;从提高茶园水库库区全年除污总效果的角度,给出了人工湿地植物的栽种选择和搭配,重点研究人工湿地在低温季节对库区污水的净化效果和不同湿地植物针对不同污染物的净化效果存在显著差异性,在人工湿地技术的实际应用中,要根据当地的条件,有针对性地种植湿地植物或合理配置湿地植物,为人工湿地在茶园水库库区的推广提供了技术指导。

Application of Constructed Wetland Technology in Sewage Purification

The constructed wetland technology has great application prospect in the purification of sewage in the tea garden reservoir area.Study on removal mechanism of artificial wetland technology in sewage purification, respectively in artificial wet-land are analyzed and expounded on the suspended matter in sewage, organic matter, nitrogen, phosphorus and heavy metal re-moval mechanism; improve the reservoir from the tea garden annual total decontamination effect,to the artificial wetland plant se-lection and collocation the purification effect of the sewage reservoir, in the low temperature season focuses on artificial wetland and wetland plants for the purification effect of different pollutants have significant differences,in the practical application of artifi-cial wetland technology,according to local conditions,the planting of wetland plants or the rational allocation of wetland plants to provide technical guidance for the promotion artificial wetland in reservoir area of tea garden.
