Abstract
AbstractTwo kinds of FeC micro‐electrolysis materials (FeC MEMs) named Fe0/FeC MEMs and Fe3O4/FeC MEMs were prepared using low‐cost biochar, chemical grade Fe0 powder and industrial iron powder. The FeC MEMs were characterized by XRD, SEM and FT‐IR. Meanwhile, the effects of sintering temperatures and mass ratios of Fe to C on the treatment high chemical oxygen demand (COD) pesticide wastewater were studied. The results display that the relative removal rate of COD reached 64% for Fe0/FeC MEMs when the sintering temperature was 400°C and the mass ratio of Fe to C was 1 : 1. For Fe3O4/FeC MEMs, and the mass ratio of Fe3O4 to C was 1 : 3, the relative removal rate of COD reached 63.71%. Hence, the chemical grade Fe0 powder could be replaced with industrial iron powder to achieve the goal of low‐cost treatment of the high COD pesticide wastewater.
