This equipment uses advanced physical, chemical and biological technologies to efficiently remove fluorescent substances in wastewater and protect the environment from harm.

[0004] Fluorescent agent wastewater treatment equipment mainly uses the following technologies: physical adsorption method, chemical oxidation method, biological degradation method, etc. Physical adsorption method uses adsorbents with high specific surface area, such as activated carbon, zeolite, etc., to adsorb and remove fluorescent substances in wastewater. Chemical oxidation method uses strong oxidizing agents such as ozone, hydrogen peroxide, etc. to decompose fluorescent substances into harmless substances. Biological degradation method uses the metabolic action of microorganisms to convert fluorescent substances into harmless substances.
