Ozone Catalytic Oxidation Tower

I. Customized Sewage Treatment Equipment - Ozone Catalytic Oxidation Tower Product Features and Advantages

1. Material and Structural Innovation

- High-efficiency catalyst design: Uses porous alumina or ceramic substrates as carriers, loaded with rare earth metals (such as manganese, cobalt, cerium) and transition metal oxides. A stable crystal structure is formed through high-temperature sintering technology (800-1200°C), with a catalyst lifespan of 3-5 years, low dissolution rate, and excellent erosion resistance.

- Proprietary tower components: Equipped with a perforated aeration system to optimize gas-liquid mixing efficiency, increasing ozone solubility by over 30%. Combined with proprietary catalytic fillers, ozone utilization can reach over 80%.

2. High-efficiency Pollutant Removal Capability

- Broad-spectrum degradation capability:

- COD removal rate of 60%-90%: Targets refractory organic compounds such as benzene series, phenols, and antibiotics;

- Decolorization rate >95%: Destroys chromophores in dye molecules, suitable for printing and dyeing wastewater;

- Simultaneous removal of ammonia nitrogen and heavy metals: For example, reduces Cr⁶⁺ in electroplating wastewater to Cr³⁺ precipitate, with an ammonia nitrogen removal rate of 50%-70%.

- Fast reaction speed: Oxidation time controlled within 30-90 minutes, with a small reactor volume, significantly higher efficiency than traditional processes.

3. Economic and Environmental Benefits

- Low operating costs: Ozone dosage reduced by 40%-60%, sludge production decreased by 40%, and treatment cost per ton of water is only 0.5-1.2 RMB.

- No secondary pollution: Organic matter is ultimately decomposed into CO₂ and H₂O, with no toxic intermediate products, and no need to adjust effluent pH (adaptable to pH 3-9).

4. Strong Environmental Adaptability

- Tolerance to complex water quality: Adapts to high salinity (TDS ≤8%), high chloride ions (Cl⁻ ≤15g/L), and fluctuations in COD concentration (e.g., sudden increase from 3000mg/L to 10000mg/L).

- Modular design: Equipment footprint reduced by 30%-50%, supporting rapid deployment and retrofitting of old water treatment plants.

5. Intelligence and Low Maintenance

- Automated control: Integrated PLC/SCADA system, real-time monitoring of water quality parameters (such as pH, ozone concentration), dynamically optimizing operating conditions.

- Easy maintenance: Long backwashing cycle (1-2 years), modular structure supports quick replacement of fillers, reducing downtime by 70%.

II. Typical Industry Applications

1. Chemical and Petrochemical Industry

- Application scenarios: Treatment of highly toxic wastewater containing benzene series, phenols, and pesticide intermediates (e.g., petroleum refining wastewater, coking wastewater).

- Case study: COD of epoxy resin wastewater in a chemical plant reduced from 5000mg/L to 800mg/L, with a decolorization rate of 98%.

2. Printing, Dyeing, and Textile Industry

- Application scenarios: Degradation of reactive dye and disperse dye wastewater, decolorization, and improvement of biodegradability (B/C ratio increased from 0.1 to 0.35).

3. Pharmaceutical and Medical Industry

- Application scenarios: Treatment of wastewater containing antibiotics and hormones, with COD removal rate exceeding 85%, creating conditions for subsequent biochemical treatment.

4. Electroplating and Metal Processing Industry

- Application scenarios: Simultaneous removal of heavy metals (e.g., Cr⁶⁺) and organic matter, degradation of complexing agents (e.g., EDTA).

5. Municipal and Landfill Leachate Treatment

- Application scenarios: Advanced treatment of pharmaceutical residues and endocrine disruptors in municipal wastewater; pretreatment of humic acid in landfill leachate, with COD removal rate of 67.5%.

6. Food and Brewing Industry

- Application scenarios: Treatment of high-concentration organic wastewater (e.g., starch wastewater, fermentation wastewater), reducing COD and decolorizing.
