Process for removal of dissolved hydrogen sulfide and reduction of sewage BOD in sewer or other waste systems

摘要

Removal of dissolved hydrogen sulfide and a reduction in BOD is achieved by the addition of nitrate ions to waste systems in an amount sufficient to stimulate growth of bacteria which utilize dissolved hydrogen sulfide in their metabolism. Specifically, about 2.4 lbs. .Iadd. nitrate .Iaddend.oxygen per lb. of sulfide is required.
