Study on Treatment of Wastewater with High-Concentration Sulfate by IC Anaerobic Reactor

Abstract:

In this study, IC anaerobic reactor was made to deal with the wastewater with high-concentration sulfate, the sludge from sewage treatment plant was put into two cells of IC reactor to domesticate sulfur-reducing bacteria (SRB), artificial water was made to simulate the wastewater with high-concentration SO₄²⁻. In order to remove the SO₄²⁻ efficiently, two stages were designed in this study: sludge domestication stage and concentration strengthening stage. In sludge domestication stage, SRB could grow normally, the removal rate of SO₄²⁻ was between 34.14% and 36.2%;in concentration strengthening stage, removal rate of SO₄²⁻ was between 26% and 26.86%,demonstrating that SRB could grow and remove SO₄²⁻ in such high-concentration SO₄²⁻( 38000 mg/L ) wastewater.
