Problems solved by technology
According to the reaction mechanism and chemical characteristics of hydroxyl radicals, hydroxyl radicals are extremely unstable. If pollutants are not captured in an instant, hydroxyl radicals will immediately undergo other reactions such as each other and annihilate instantly. At this time, hydroxyl radicals do not play a strong role. Oxidation treatment of pollutants, the effective utilization rate of hydroxyl radicals generated by the system is low, so the usual advanced oxidation method has long reaction time, large amount of oxidant dosage, high treatment cost and other disadvantages
Moreover, the oxidation reaction treatment device usually adopts one reaction chamber, and there is usually one oxidant dosing point, the reaction effect is not good, and there are problems such as large equipment volume, single structure of the device, and high equipment cost.

Besides, the degradation-resistant waste water treatment system has the advantages of being low in operation cost and high in treatment efficiency.
Description
technical field [0001] A wastewater treatment system is widely used in the field of industrial wastewater treatment. More specifically, it relates to an industrial refractory wastewater treatment system. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety at all times. For the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage. Although the treatment of industrial wastewater began as early as the end of the 19th century, and a large number of experimental studies and production practices were carried out in the following half century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved. [0003] At...
