- Abstract
Three types of local plants (canna, calamus, umbrella,)were chosen to construct ecological floating-beds for contamination control atshiyanbaierhe. Differences in plant growth and the capacity of sewage treatment were compared. Results showed that three plants can uptake the nitrogen, phosphorus and organic matter in water effectively, but significant differences were found among these three species in absorption. The removal rates of CODcr using above plants were ranged from 50.1% to 75.6%, those of TN were between 50% to 69.3% and TP were between 70.4% to 89.2%. The efficiency of these three plants from high to low is canna calamus and umbrella. Canna had the largest net increase of biomass while umbrella had the smallest. The content of nitrogen and phosphorus in overground parts of plants were higher, thus the nutrient could be transferred from water by reaping the plants. It was recognized that canna could be the best plant to employ on the ecological floating-beds in baierhe area and could mix with calamus in order to improve the ecological diversity.
