Laboratory Study on the Performance of Domestic Wastewater Biofilters Made of Arundo Donax L.

Abstract:

Filter systems have the ability to remove pollutants from wastewater. However, to increase the treatment efficiency, the filter made of plants has been recommended which has been called the biofilter. The objective of this study was to examine the performance of biofilter made by Arundo donax L. on domestic wastewater treatment. In this paper, a laboratory study using vertical flow constructed wetlands planted with Arundo donax L. and without any other plants were conducted. For the biofilter planted in Arundo donax L., the removal of TN, NH4+-N and TP 89%, 93% and 98% respectively. In particular, we also got the nitrogen and phosphorus content of different parts of Arundo donax L. which was divided into root, stem and leaves. For the total nitrogen content in the plant, there is a quantitive relationship of stem
