Efficient Fenton reaction systemfeature

1. Fluidized bed Fenton (FBR-FENTON) is a new technology that combines homogeneous chemical oxidation (H2O2/Fe2+), heterogeneous chemical oxidation (H2O2/FeOOH), and fluidized bed crystallization functions to crystallize or coat the hydroxylated iron oxide (FeOOH) produced by the Fenton method on the surface of the fluidized bed carrier using a fluidized bed.

2. The FERED-FENTON oxidation reactor adopts advanced principles and uses ferrous ions (Fe2+) as a catalyst to catalyze hydrogen peroxide to produce highly oxidizing hydroxyl radicals (• OH), which oxidize organic matter and generate trivalent iron ions (Fe3+). The trivalent iron ions are reduced to ferrous ions at the cathode of the electrolysis cell. Therefore, the use of ferrous ions circulating in the reactor can be utilized to reduce the amount of catalyst used, decrease the amount of sludge generated by trivalent iron, and significantly reduce operating costs.

3. Fluidized Bed Crystallizer (FBC) technology utilizes other salts (such as carbonates, phosphates, oxalic acids, fluorides, or sulfides) to achieve co low solubility and steady-state crystal characteristics, allowing crystals to grow on a carrier in a fluidized bed to remove cations (such as metal ions) and anions (such as phosphate ions) from wastewater. The crystallization technology uses 0.2-0.5mm silica sand carrier as the crystallization nucleus in the crystallization tank. The wastewater and added reagents to be treated enter from the bottom of the reaction tank and flow upward. There is a return water pipeline outside the reaction tank to adjust the supersaturation of the inlet water and achieve the upstream velocity of the carrier, so that the inorganic ions to be treated form steady-state crystals on the surface of the silica sand carrier. When the crystal particle size reaches 1-2mm, they are discharged from the tank for recycling or waste reduction and disposal.
