Problems solved by technology
The invention relates to a method for carrying out injection-reducing standard discharging treatment on high-sulfur wastewater of an oil-gas field. According to the method disclosed by the invention, technologies of negative-pressure desulfurization, chemical reaction desulfurization, flocculating settling, ceramic membrane filtering, high-pressure reverse osmosis and ozone catalytic oxidation are adopted, so that the purpose of deeply removing sulfide, suspended matters, organic matters, chloride and oil in the high-sulfur wastewater of oil-gas field can be realized, the sulfur content, the suspended matter content and the oil content in high-pressure reverse osmotic concentrated water can meet the reinjection water standard of the oil-gas field, and effluent after ozone catalytic oxidation is subjected to standard discharging.
