Biofilter for the treatment of sour water

摘要

A process for oxidizing the sulfide (H2S, HS-, S-2) in sour water to convert the sulfide to sulfate by producing a sulfide tolerant strain of Thiobacillus denitrificans and then co-immobilizing the T. denitrificans and CaCO3 on or within a carrier to form the biofilter. The sour water is contacted with the biofilter in a continuous process.
