摘要
A process for treating oilfield waste water includes contacting the oilfield waste water with hydrogen peroxide, the oilfield waste water comprising sulfide; oxidizing the sulfide to sulfur; and precipitating the sulfur to form treated water from the oilfield waste water. A process for recycling oilfield waste water includes combining the oilfield waste water and hydrogen peroxide, the oilfield waste water comprising sulfide; oxidizing the sulfide to sulfur; forming a precipitate comprising a colloidal sulfur precipitate, a bulk sulfur precipitate, or a combination comprising at least one of the foregoing; removing the precipitate from the oilfield waste water to form treated water; introducing an additive to the treated water; and disposing the treated water in a subterranean environment.
