Rainfall runoff contains a huge number of pathogenic bacteria that seriously deteriorate water quality. Bioretention is an effective approach to removal of pathogenic bacteria from rainwater. This study uses sandy soil, fly ash, slag, sandy soil+5% fly ash, and sandy soil+5% slag as media to evaluate the adsorption of fecal Escherichia coli. The mechanisms of the five media conform to the Langmuir?s isotherm adsorption equation, and a pseudo-first-order kinetic model is adopted to reveal the absorption kinetics.
