    "patent_abstract": "A method of treating selenium-containing wastewater comprises performing anoxic biological treatment of the selenium-containing wastewater to produce a first liquid including a residual dissolved selenium species, introducing an oxidant into the first liquid to form an oxidant-treated first liquid, introducing a coagulant into the oxidant-treated first liquid to form a second liquid having selenium-containing solids, and removing the selenium-containing solids from the second liquid in a solids-liquid separation operation.",
