摘要
Phytoremediation is a low-cost, environmentally friendly, and sustainable technology that can utilize vegetation and microorganisms to avoid eutrophication and purifying water environment. The ability of five different living aquatic plants of nitrogen (N), phosphorus (P), and chemical oxygen demand (CODcr) removal were investigated in pilot scale constructed wetlands (CWs). Aquatic plant mixes significantly improved CODcr removal and plant tissue uptake of nitrogen and phosphorus. The wetland performance of mixed plantings was also influenced by the specific species. When assessing pollutant removal in CWs, PNM performed better within mixtures, a possible synergistic effect, while TNV performed poorly, a possible antagonist effect. The nutrient uptake within plant tissues by mixed plants was always a synergistic effect. Aquatic plant mixes significantly increased the rhizosphere microbial diversity and promoted the growth of functional heterotrophic denitrifying flora.
