Title: METHOD FOR TREATING HYDROGEN SULFIDE-CONTAINING WASTE WATER AND APPARATUS THEREFOR
Abstract:
Provided are: a method for treating hydrogen sulfide-containing waste water that is capable of removing hydrogen sulfide efficiently even from waste water with a high concentration of hydrogen sulfide, generating little post-treatment pollution and without requiring large-scale equipment; and an apparatus therefor. The method for treating hydrogen sulfide-containing waste water comprises the adjustment of the hydrogen sulfide-containing waste water to a pH appropriate for oxidation of hydrogen sulfide, the addition of an oxidizing agent to the adjusted pH waste water to acidify the hydrogen sulfide in the waste water to sulfur and deposit same, and the removal of the deposited sulfur by solid-liquid separation.
