Problems solved by technology

The existing chemical catalytic reaction usually uses an independent metal filter for solid-liquid separation and recovery of catalyst, which requires manual cleaning of the filter to recycle the catalyst, which not only easily causes the loss of catalyst during the filter cleaning process, but also increases the risk of wastewater leakage. At the same time, due to the decrease of catalyst concentration caused by the filtration of catalyst, it is not suitable for continuous operation of wastewater treatment
[0004] However, the use of conventional polymer filter elements such as PP cotton and fiber filters not only require an independent filter device, but the catalyst cannot be completely recovered after filtration, resulting in the loss of the catalyst and increasing the cost of wastewater treatment
The independent filtration system often causes the separation of the catalyst and the reactor, which cannot ensure a constant catalyst concentration in the reactor, which is not conducive to effective wastewater treatment

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an advanced oxidation reaction system for wastewater treatment. Background technique [0002] Heterogeneous catalytic oxidation refers to the process in which pollutants react with oxidants on the surface of the catalyst and are removed by means of mechanical or fluid agitation. The catalyst promotes the oxidant to generate free radicals to effectively remove oxidized and mineralized pollutants. [0003] In the currently known wastewater oxidation process, there is no process and equipment for catalytic oxidation of wastewater treatment using powdered catalysts. Catalysts are usually expensive, and it is necessary to reduce the waste caused by repeated use of catalyst loss and reduce the cost of wastewater treatment. The existing chemical catalytic reaction usually uses an independent metal filter for solid-liquid separation and recovery of catalyst, which requires manual cle...
