Abstract

The invention discloses a method for treating high-concentration organic wastewater by utilizing dielectric barrier discharge-wastewater treatment combined equipment. Firstly, gas rich in active particles is produced by utilizing the equipment and then is in full contact with the to-be-treated high-concentration organic wastewater in an equipment reaction column for reaction to realize the removalof contaminants in the organic wastewater; the dielectric barrier discharge-wastewater treatment combined equipment consists of a gas supply pump, a gas flow meter, a power supply, a high-voltage electrode, a grounding electrode, a rotary gas distributor, a gas flow regulating valve, a titanium steel aeration head, the wastewater treatment reaction column and a wastewater inlet and outlet openingin a reaction column body. A large quantity of gas rich in the active particles can be produced by utilizing the method and the equipment, and full contact between the active particles and the organic wastewater is ensured; no chemical reagent is required to be added in the treatment process, and the strict requirements for a discharge technology for wastewater treatment are reduced; the treatment efficiency is improved, and the cost and the energy consumption are reduced. Therefore, the method has a greater industrial application value.

Description
