Abstract

The invention discloses a method and a device for treating wastewater through an electric synergistic oxidation reaction. The method comprises the following steps: an electrolytic reaction tank is divided into an electrolytic anode region and an electrolytic cathode region by using an electrolytic separator; the electrolyte of the electrolytic anode region comprises a persulfate-containing compound, soluble salt of multivalent metal ions, soluble variable-valence metal salt and to-be-treated wastewater; the electrolyte of the electrolytic cathode region is an electrolyte solution or water; the redox potential value of the electrolyte in the electrolytic anode region is controlled to be not lower than 300mV; and the electrolytic separator is a material capable of separating the electrolytic reaction tank and effectively preventing anions in the electrolyte in the electrolytic anode region from migrating to the electrolytic cathode region under the acting force of an electric field. The device comprises an electrolytic reaction tank, an electrolytic anode, an electrolytic cathode, an electrolytic separator, an electrolytic power supply and an oxidation-reduction potential detection device. By adopting the method and the device disclosed by the invention, organic matters, ammonia nitrogen and reducing substances in wastewater can be quickly and effectively treated.

Description

technical field [0001] The invention belongs to the field of industrial wastewater treatment, and in particular relates to a method and a device for treating wastewater by electro-cooperative oxidation reaction. Background technique [0002] In industrial production and wastewater treatment, there is often a need to remove impurities and pollutants in liquids. For example, industrial wastewater often contains a variety of pollutants harmful to the human body or the natural environment. It needs to be decomposed or separated from the liquid by physical, chemical, and biological methods. After the wastewater to be treated reaches the environmental protection discharge standard to be able to discharge. Another example, in the chemical industry, in order to avoid the impurities in the production raw materials from affecting the production quality, it is necessary to pre-treat the impurities in the production raw materials before entering the next step of production. Among the ...
