As a powerful assistant in the field of sewage treatment, the Fenton reactor is widely used and highly efficient. It cleverly uses the chemical reaction of hydrogen peroxide and ferrous ions to generate highly oxidizing hydroxyl radicals. These free radicals, like warriors, quickly attack and decompose organic pollutants in wastewater and convert them into harmless small molecules. Whether it is municipal sewage or industrial wastewater, the Fenton reactor can show its prowess and effectively remove pollutants such as COD, BOD, color, odor, etc. to ensure that the effluent water quality meets the standards. It is easy to operate and has high treatment efficiency, making an indispensable contribution to the environmental protection cause. By fixing a special catalyst in a special reaction vessel, it is a new technology that combines the functions of homogeneous chemical oxidation, heterogeneous chemical oxidation, fluid bed crystallization and ferrite reduction and dissolution. This reactor improves the traditional Fenton oxidation method.
Compared with the Fenton stirring and mixing reaction, it only requires a lower dosage of reagents and a lower sludge output. This reactor system allows most of the Fe3+ produced by the Fenton process to crystallize and attach to the surface of the fluidized bed Fenton carrier. The crystallized Fe3+ iron salt forms a synergistic effect with the Fenton system and then converts to Fe2+ over and over again, which can greatly reduce the amount of chemical sludge produced by the traditional Fenton process. The amount of H2O2 added is reduced by more than 20%, the amount of Fe2+ added is reduced by more than 50%, and the amount of sludge is reduced by more than 40%, which effectively increases the COD removal rate by more than 10%, and saves 30% to 50% of the treatment and operation costs.
1. Applied to the deep treatment of industrial wastewater such as printing and dyeing, chemical industry, petrochemical industry, leather, papermaking, and pharmaceutical industry.
2. Biochemical pretreatment of difficult-to-degrade, high-COD wastewater.
