Sponge effect of aerated concrete on phosphorus adsorption-desorption from agricultural drainage water in rainfall

Abstract: In the initial stage of the rainfall, the nutrient element phosphorus (P) in the farmland, one of the most important factors causing agricultural non-point source pollution, flows into agriculture drainage ditches rapidly, and an instantaneous phosphorus peak value in the ditch water often occurs. Aerated concrete with high P adsorption properties was chosen as the experiment material in the laboratory to reduce the instantaneous P peak value in the drainage water in the initial stage of the rainfall. The thre… Show more

“…For example, Zhang and Fu (2020) 106 observed phosphate desorption of 5% from aerated concrete using distilled water after 48 h, and Deng and Wheatley (2018) 100 verified phosphate desorption of 4 to 7% from recycled triggered concrete using distilled water at 180 rpm after 24 h.…”
