Abstract

A batch experiment was used to investigate the influence of common heavy metals Cr(VI), NI(II), Cu(II) on sulfur autotrophic short-cut denitrification. Experimental results show that low concentrations (1-3 mg/L) of heavy metals have little effect on sulfur autotrophic shortcut denitrification, and high concentrations (4-10 mg/L) of heavy metals have obvious effects on sulfur autotrophic short-cut denitrification. Inhibition. The doserape model is used to fit the doseeffect curve of heavy metals, and the IC₅₀is used to judge the toxicity. The order of the IC₅₀of each heavy metal is: Cr(VI)>NI(II)>Cu(II). The effects of two heavy metals in the binary system of Cu(II) and NI(II) are antagonistic.
