Effect of Plant Disposition on Purification of Eutrophicated Circulating Water in Surface Flow Wetlands.
摘要
Abstract
Effects of plant disposition on purification of eutrophicated circulating water in surface flow wetlands were studied in the Beijing Wildlife Rescue Center.Results show that when its hydraulic loading remained to be 1.46 m · d-1 for 24 hours, the surface flow wetland, as a whole, could reach to 13.26, 57.76, 62.44 and 70.72 mg · m-2 · d-1 in perunit-area removal rate of total phosphorus (TP), total nitrogen (TN), chemical oxygen demand (CODCr) and total suspended solids (TSS), respectively.Eichhornia crassipes was the highest in removing TP and TN, being 12.82 and 62.95 mg · m-2 · d-1 , respectively, while Nymphoides peltatum and Oenanthejavanica the lowest being 6.61 and 36.94 mg ·m-2 · d -1 , respectively.Regression analysis indicated that TP and TN in the effluent was exponentially related to that in the influent, separately.CODCr removal rates of the macrophytes, regardless of species, decreased with the elapse of time.However, N.peltatum was the highest in removal rate, being 67.14 mg · m-2 · d-1, while Acorus calamus the lowest being 45.43 mg · m-2 · d-1.Pistia stratiotes and Sparganium stoloniferum were the lowest in TSS removal rate ( P ＜0.05 )and the rates varied in a narrow range (22.96 -33.95 mg · m-2 · d-1) with time.The pH values of Typha orientaliss,E.crassipes, A.calamus and Sagittaria trifolia were obviously lower than other units.关键词
