Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a multiphase Fenton automated management water treatment equipment. Background Technology

[0002] The Fenton reaction is an inorganic chemical reaction in which a mixed solution of hydrogen peroxide (H₂O₂) and ferrous ions (Fe²⁺) oxidizes many known organic compounds, such as carboxylic acids, alcohols, and esters, into inorganic forms. This reaction has a high capacity for removing recalcitrant organic pollutants and is widely used in the treatment of wastewater from dyeing and printing, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and diphenylamine wastewater. Fenton's reagent can oxidize most organic matter in water, and is particularly suitable for the oxidation treatment of organic wastewater that is difficult to biodegrade or where conventional chemical oxidation is ineffective. COD, or Chemical Oxygen Demand, is an indicator used to measure the concentration of organic pollutants in water bodies, especially those substances that can consume oxygen through oxidative chemical reactions; it is commonly used to assess the degree of water pollution, particularly the content of organic matter.

[0003] Existing water treatment equipment cannot adjust the mixing ratio of wastewater and oxidizing agent online, requiring repeated adjustments based on different operating conditions. When the wastewater after mixing the agent reacts in the tank, the external temperature affects the catalytic efficiency inside the tank. Utility Model Content
