Comparison of useful terrestrial and aquatic plant species for removal of nitrogen and phosphorus from domestic wastewater

摘要: Abstract To develop a low cost and energy-saving wastewater treatment technique in combination with resource recycling amenity functions, we constructed plant bed filter ditch which useful terrestrial aquatic plants can be utilized for nitrogen phosphorus removal from wastewater. Screening studies were conducted to evaluate compare the effectiveness of 20 kinds species are economically important or exhibit on aesthetic value, including 13 species, domestic treatment. Artificial containing mg L-1 Nand 3.3 P, was supplied at rate about 1.41–2.08 g m-2 d-1 N 0.20–0.33 P. The experiments performed glass house windows opened April November. ditches showing high P rates planted exhibited biomass production rates. In case papyrus ditch, exceeded 0.8 0.15 ...
