After such industrial wastewater has undergone conventional physicochemical and biochemical secondary treatment, the wastewater still contains a large amount of toxic and biologically refractory organic pollutants, which require further advanced treatment to meet the discharge standards or reuse requirements. Therefore, the development of advanced treatment technology for industrial wastewater is of great significance to water conservation, emission reduction and environmental protection.

For this kind of refractory wastewater, the existing treatment technologies at home and abroad include enhanced biodegradation, coagulation, adsorption, membrane separation and advanced oxidation technology. Among them, advanced oxidation technology uses hydroxyl radicals with strong oxidizing ability to oxidize pollutants in water, making them go through a series of intermediate processes, and finally generate CO2 and other inorganic ions. It is an advanced advanced wastewater treatment technology. Advanced oxidation technologies include ozone catalytic oxidation, photocatalytic oxidation, Fenton oxidation, electrochemical oxidation, ultrasonic cavitation, microwave catalytic oxidation, and supercritical oxidation.

However, only relying on advanced oxidation technology alone to achieve stricter wastewater discharge standards, the treatment cost is high, and the one-time investment is large. In order to solve the technical and economical limitations of advanced oxidation technology, especially in the field of biodegradable toxic and harmful organic pollutants, researchers have invented a variety of "advanced oxidation + biochemical" combined processes, including: Fenton + exposure Gas biological filter, ozone + aeration biological filter, ozone catalytic oxidation + aeration biological filter, ozone catalytic oxidation + membrane bioreactor, etc. These "advanced oxidation + biochemical" combined processes can effectively ensure that the effluent reaches the standard with reasonable investment and operating costs, and have gradually become a preferred technology for advanced treatment of refractory wastewater. However, currently limited by the equipment, such a combined process of "advanced oxidation + biochemical" cannot achieve the desired effect.
