Disclosed is a method for treating sulfur-containing organic wastewater by integrating an energy supply unit and a treatment unit into an integrated device. The treatment unit is used to purify sulfur-containing organic wastewater with an initial concentration of organic sulfur, so that the organic sulfur content in the treated sulfur-containing organic wastewater is within a preset range to enable the device to efficiently purify and treat sulfur-containing organic wastewater with different initial concentrations of organic sulfur, the efficiency of purifying sulfur-containing organic wastewater can be improved to a certain extent, the purification cost can be reduced, and the competitiveness of enterprise can be enhanced.

Method for treating sulfur-containing organic wastewater

The invention discloses a biological desulfurizer for removing organic sulfur in fracturing flowback fluid and application thereof. The biological desulfurizer includes a compound with a triazine structure formed by modifying chitosan with aldehydes and inorganic salts. The triazine structure has a good removal effect on hydrogen sulfide and organic sulfur such as mercaptan and sulfide. The biological desulfurizer of the invention has a sulfur capacity of up to 250 g/kg and a desulfurization efficiency of over 95% in 15 min. It can effectively remove the stink of sulfur-containing working water, improve the working environment of the well site, and reduce the impact of sulfur compounds on the atmospheric environment during the development of oil and gas fields.
