IFenton moderate catalytic oxidation technology

IFenton technology is based on the traditional Fenton oxidation advanced treatment technology, combined with years of engineering application experience, the R&D team carries out process innovation and improvement, and forms a wastewater advanced treatment technology that complements the wastewater biochemical treatment process well, has a wide range of application, low treatment cost and good treatment effect.  

IFenton process technology is a "modified Fenton" process. According to the molecular structure characteristics of residual organic pollutants in wastewater after biochemical treatment, through the precise control of reaction conditions (reaction pH, ORP, time, dosage, dosage order, etc.), the degradation function of catalase is simulated. The organic pollutant molecules in wastewater are moderately oxidized by controlling the generated hydroxyl radical, and the carboxylated pollutant molecules are complexed with iron ions generated by the catalytic reaction to generate iron carboxylate complex with large molecular weight, and its water solubility is reduced. Then, wastewater purification is realized by means of solid-liquid separation.  

Scope of application: The technology is suitable for pulp and paper making, textile printing and dyeing, pesticides, pharmaceuticals and other industrial wastewater and industrial park wastewater advanced treatment, can efficiently remove wastewater COD, chroma, total phosphorus, suspended solids and other pollutants. The treatment effect is better than other advanced oxidation technologies such as ozone catalysis.


Competitive advantage

The essence of IFenton wastewater advanced treatment technology to remove pollutants in wastewater is to convert dissolved organic pollutants into insoluble substances (i.e., sludge), which is a process of transferring pollutants from liquid phase to solid phase. The essence of conventional Fenton oxidation technology to remove pollutants in wastewater is to break the C-C bond of dissolved organic pollutants and convert them into CO2, which is a process of transferring pollutants from liquid phase to gas phase. The hydrogen peroxide consumed in the reaction process of the two different pollutant conversion pathways is quite different. The hydrogen peroxide consumption of IFenton technology is only 10-20% of that of Fenton oxidation technology.


  • Typical wastewater treatment effect and operating cost of printing and dyeing park

    The wastewater treated by the project is the effluent of the secondary sedimentation tank after biochemical treatment in the sewage treatment plant of the park. In the advanced treatment project, the influent CODCr is 120-160mg/L, the color is 200-300 times, and the TPIs 0.8-1.8mg/L. Advanced treatment effluent CODCr≤50mg/L, chroma ≤15 times, TP ≤ 0.5mg/L, wastewater advanced treatment agent cost 0.5-0.8 yuan/cubic.
