Description

Equipment for comprehensively treating wastewater based on advanced oxidation method Technical Field The invention relates to the technical field of wastewater treatment, in particular to a device for comprehensively treating wastewater based on an advanced oxidation method. Background With the continuous acceleration of industrialization and urbanization, the discharge amount of wastewater is increasing. These wastewater contains various contaminants such as organic matter, heavy metal ions, nitrogen and phosphorus nutrients, etc. If the water is directly discharged into the environment without effective treatment, serious damage can be caused to the water body, soil and ecological system, and the human health, the survival of aquatic organisms and the sustainable utilization of water resources are threatened. Advanced oxidation is an emerging wastewater treatment technology whose main principle is to oxidatively decompose pollutants in wastewater by generating radicals having strong oxidizing properties such as OH radicals. The OH free radical has extremely high oxidation potential, can be subjected to rapid oxidation reaction with most of organic matters in the wastewater in a non-selective way, and finally is degraded into carbon dioxide, water and harmless inorganic ions. The existing Fenton oxidation method needs to consume a large amount of chemical agents such as ferrous sulfate, hydrogen peroxide and the like, can generate a large amount of iron mud, has higher difficulty in subsequent treatment, has lower light energy utilization rate and slower reaction rate, has limited solubility of ozone in water and has unsatisfactory treatment effect when in use, so that the existing advanced oxidation method for treating wastewater has to be improved.
