Abstract

The invention discloses a method and device for treating triclocarban-containing wastewater through cooperation of plasma and a TiO2-ACFs composite catalyst. The method includes the steps that the triclocarban-containing wastewater is introduced into a reaction still between a positive electrode and a negative electrode; the TiO2-ACFs composite catalyst is pre-placed in the reaction still; a power source is switched on, and the triclocarban-containing wastewater is subjected to cycle treatment through cooperation of the dielectric barrier discharge plasma and TiO2-ACFs. Triclocarban in the wastewater is degraded through .OH and other active particles and ozone generated after discharge through cooperation of the plasma and the TiO2-ACFs composite catalyst, a UV effect and an adsorption effect, the treatment effect is good, operation is easy, no other pollutants are generated, by means of the method, the triclocarban-containing wastewater can be cleanly and efficiently treated, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a plasma synergistic TiO 2 -Method and device for treating triclocarban-containing wastewater with ACFs composite catalyst. Background technique [0002] In recent years, PPCPs have attracted widespread attention, mainly because the discharge of PPCPs that have not been effectively treated in large quantities into water bodies will cause serious environmental pollution and further cause harm to humans or other organisms. Triclocarban (TCC), as a new type of high-efficiency broad-spectrum antibacterial agent, can be widely used as a medical disinfectant. Washing powder, laundry detergent, trauma ointment, beauty cosmetics, must-use foam ointment, toothpaste, mouthwash, antibacterial tableware detergent, wound disinfectant, fabric antibacterial finishing agent, medical disinfectant, fiber textiles, underarm odor and beriberi products Bactericidal, antibacterial and deodorizing ingr...
