Abstract

This paper studied the effect of different inflow water, heavy metal (Cu, Zn, Cd) concentration and rainfall interval on heavy metal reduction in bioretention facility. The results showed that the removal ability of heavy metals was different among the three bioretention facilities, and the removal effect of Cu was the best, while the removal effect of Cd was not stable. High inflows reduce the reducton efficiency of heavy metals in bioretention facilities. The concentration changes of heavy metals in influent did not significantly change the reduction efficiency. After comprehensive comparison, it was found that the bioretention facility with (sand + fly ash) as filler had the best reduction effect on heavy metals, and the removal rate reached 88%. The research results can provide basic data support for the design and application of bioretention facility.
