湿地植被对污水净化效果分析研究

Analysis on Effect of Vegetation Planting in Constructed Wetland on Sewage Purification

人工湿地植被种植对污水净化具有显著性的改善作用,分析人工湿地植被种植与污水净化的量化关系,分析人工湿地植被种植对污水改善的原理,建立生态植被污水净化处理模式,采用多元回归分析方法人工湿地植被对水质控制和小型富营养水体生态恢复的效益因素,以营养物的去除率、重金属的去除率以及有机物去除率为指标,分析人工湿地植被种植对污水净化的生态学改善模型。研究表明,人工湿地植被种植能增加水体透明度,降低水体中的富营养物和重金属等物质,对污水具有显著性的改善作用。

Artificial wetland vegetation planting has a significant improvement on sewage purification,analysis of the relationship between artificial wetland vegetation planting and sewage purification,analysis of the principle of artificial wetland vegetation to improve sewage. The model of ecological vegetation sewage purification was established,and the multiple regression analysis was used to analyze the effect of constructed wetland vegetation on water quality control and ecological restoration of small eutrophic water bodies,and the removal rate of nutrients was taken into account. The removal rate of heavy metals and the removal rate of organic matter were used as indicators to analyze the ecological improvement model of sewage purification by planting artificial wetland vegetation. The results showed that the planting of artificial wetland vegetation could increase the transparency of water body. Reducing the contents of eutrophication and heavy metals in water can significantly improve the quality of sewage.
