FBR-Fenton Chemical Treatment Technology
FBR-Fenton Chemical Treatment Technology

Introduction

Chemical oxidation is to decompose organics to carbon dioxide and water with oxidant, and the most effective technology is Advanced Oxidation Processes (AOPs). Fenton technology is one of AOPs, which utilizes H2O2 to generate ‧OH (the oxidation potential is only lower than fluorine) using Fe2+ as catalyst. The mechanism is:

H2O2 + Fe2+ → ‧OH + OH- + Fe3+ → Fe(OH)3

FBR-Fenton oxidation (FentonⅣ) is one kind of Fenton family methods. The idea of FBR-Fenton oxidation combines homogeneous Fenton oxidation, heterogeneous H2O2/FeOOH oxidation, fluidized-bed crystallization and reduction/dissolution of FeOOH. The suitable range of COD is less than 500 mg/L. The advantages of FBC-Fenton oxidation are low dosage of Fe2+ and decrease 60% generated sludge compared to Fenton oxidation.

The advantages of Fenton regent are:

  1. Environmentally friendly：Not like other oxidants such as NaOCl, no chlorinated organic byproducts generates.
  2. Small construction space：The oxidation is fast so that the required reaction time is only 0.5~2 hrs compared to bio-treatment. Therefore, the space of reactor can be reduced.
  3. High flexibility：During operation, when high concentration wastewater occurs, it only needs to increase the dosages of Fe2+ and H2O2.
  4. Easy to operate：Only chemical addition and pH control are required.
  5. Low installation cost：Only 1/3~1/4 compared to conventional bio-treatment system.
  6. Strong oxidation：Many kinds of toxic chemicals such as vinyl chloride, BTEX, chlorobenzene, 1,4Dioxane, aldehyde, pentachlorophenol, polychlorinated biphenyl, TCE, DCE, PCE, EDTA, MTBE, MEK, etc.
