摘要
环境污染物降解人工湿地技术是近年来广泛推广的利用基质、水生植物和微生物之间的协调作用来降解环境污染物的新技术。研究了人工湿地对二级出水中总磷去除效果的影响,分别以陶粒和沸石作为湿地基质,选取水生植物香蒲和芦苇,考察不同基质和水生植物对总磷去除效果的影响。研究结果表明:人工湿地对总磷的去除主要是滤料的吸附等物理作用,植物对总磷的去除效果不明显。陶粒作为基质对磷的吸附能力高于沸石作为基质对总磷的吸附能力。芦苇对总磷的吸收效果优于香蒲对总磷的吸收效果。
The environmental contaminant biodegradable artificial wetland technology is a new technology that has been widely used in recent years. It utilizes the coordination of matrix,aquatic plant and microorganism to degrade environmental pollutants. In this paper,the effects of artificial wetland on the removal of total phosphorus in secondary water were studied,and the effects of different substrates and aquatic plants on total phosphorus removal efficiency were investigated by using ceramic granules and zeolite as the wetland substrate,and cattail and reed as the aquatic plants. The results indicate that the removal of total phosphorus in artificial wetland is mainly due to the physical effects of the filter material,such as the adsorption.Plant has no obvious effect on the total phosphorus removal.The adsorption capacity of ceramsite for phosphorus is higher than that of zeolite.The total phosphorus absorption effect of reed is better than that of cattail.
