Ozone catalyst filler for refractory wastewater treatment

Conventional ozonation (direct oxidation) is selective towards target pollutants and suffers from low ozone utilization and high operating costs. Our Refractory Wastewater Treatment Ozone Catalyst Filler achieves a qualitative leap through its unique physicochemical structure:

Efficient catalytic generation of free radicals: The filler uses high-strength, large-specific-surface-area porous materials (such as gamma-alumina, diatomite, etc.) as carriers, and through a special process, loads multiple transition metal oxides such as manganese, copper, cerium, and iron as active components. These active sites efficiently catalyze ozone (O₃) molecules, decomposing them in water to produce highly oxidative hydroxyl radicals (·OH).

Non-selective attack and complete mineralization: Hydroxyl radicals have an oxidation potential as high as 2.8 eV, second only to fluorine. They non-selectively attack and destroy the molecular structures of most refractory organic compounds (such as benzene rings and heterocycles), ultimately breaking them down into harmless carbon dioxide and water, achieving complete "mineralization" rather than simple morphological transformation.

II. Specific Applications and Results in Industrial, Chemical, and Heavy Metal Sectors

Chemical park wastewater: Chemical wastewater has extremely complex compositions, often containing toxic substances such as phenols, anilines, polycyclic aromatic hydrocarbons, and halogenated hydrocarbons. Refractory Wastewater Treatment Ozone Catalyst Filler can effectively break the molecular chains of these substances, significantly improving the biodegradability of biochemical tailwater (B/C ratio), laying a solid foundation for subsequent advanced treatment or direct compliance discharge.

Heavy metal industry wastewater: The challenge in this field lies not only in the heavy metal ions themselves but also in the complexed heavy metals formed with organic matter (such as EDTA-Cu, nickel citrate, etc.). Traditional precipitation methods cannot break down the complexes, leading to excessive heavy metal levels. Refractory Wastewater Treatment Ozone Catalyst Filler generates ·OH that preferentially destroys the organic shell of the complexing agents, releasing heavy metal ions, which are then easily removed through subsequent precipitation processes, simultaneously achieving compliance for both COD and heavy metals.

Pharmaceutical and pesticide wastewater: Residual antibiotics, endocrine disruptors, and pesticide parent compounds in wastewater pose significant risks to the ecological environment and human health. Refractory Wastewater Treatment Ozone Catalyst Filler can precisely and effectively destroy the pharmacophore and toxic structures of these substances, eliminating their biological activity and effectively controlling environmental risks.

Dyeing and coking wastewater: For wastewater with high chroma, high ammonia nitrogen, and containing large amounts of heterocyclic compounds such as anthracene and naphthalene, this filler performs excellently in decolorization, deodorization, and toxicity degradation, resulting in clear and transparent effluent with significantly improved sensory indicators.
