Sewage Treatment Equipment - Electrocatalytic Oxidation Equipment

I. Customized Sewage Treatment Equipment - Electrocatalytic Oxidation Technology Features

1. Material and Process Innovation

- Electrode Design: Utilizes catalytic anodes (such as DSA plates), with titanium-based coatings or precious metals (e.g., platinum, palladium) as the core, enhancing oxygen evolution overpotential, reducing side reactions, increasing current efficiency by 30%-50%, and extending electrode lifespan to 3-5 years.

- Modular Structure: The equipment consists of a power control cabinet, pre-catalytic reactor, catalytic oxidation reactor, and dosing device, supporting customized production and adapting to different treatment scales (1-500 m³/d).

2. Efficient Reaction Mechanism

- Free Radical Oxidation: Generates strong oxidizing substances such as active hydrogen (H·) and hydroxyl radicals (·OH) through high-voltage pulsed current electrolysis, rapidly degrading organic matter, achieving COD removal rates of 60%-90% and ammonia nitrogen removal rates exceeding 90%.

- Multifunctional Synergy: Combines air flotation, sterilization, and disinfection, simultaneously removing color, heavy metals, and suspended solids (SS), with decolorization rates >95%.

3. Intelligent Control

- Dynamic Adjustment: Equipped with PLC/SCADA systems, real-time monitoring of parameters such as pH and conductivity, dynamically adjusting current, voltage, and dosing volume to adapt to water quality fluctuations (e.g., COD suddenly increasing from 5000 mg/L to 15000 mg/L).

II. Customized Sewage Treatment Equipment - Core Advantages of Electrocatalytic Oxidation

1. Economic Efficiency and Low Operating Costs

- Low Energy Consumption: High unit spatiotemporal efficiency, with a treatment cost per ton of water of only 0.8-1.2 RMB, reducing costs by over 50% compared to traditional processes.

- Sludge Reduction: Sludge production reduced by 30%-50%, saving subsequent disposal costs.

2. Environmental Friendliness

- No Secondary Pollution: Reaction products are primarily CO₂ and H₂O, with no risk of heavy metal leaching, and effluent requires no secondary neutralization.



3. Strong Environmental Adaptability

- Tolerance to Complex Water Quality: Adapts to high salinity (TDS ≤8%), high chloride ions (Cl⁻ ≤15g/L), and low conductivity wastewater, with a wide pH application range (2-9).

4. Easy Maintenance

- Insoluble Coating Electrodes: Resistant to wear, with long backwashing cycles (1-2 years), modular design supports quick replacement of parts, reducing downtime by 70%.

III. Typical Application Areas

1. Chemical and Petrochemical Industries

- High-Concentration Organic Wastewater: Treats wastewater containing benzene compounds, phenols, and pesticide intermediates, with COD removal rates >85%.

2. Electroplating and Metal Processing Industries

- Heavy Metal and Complexing Agent Treatment: Simultaneously removes pollutants such as Cr⁶⁺, Ni²⁺, and EDTA, reducing wastewater toxicity.

3. Municipal and Landfill Leachate

- Advanced Treatment: Degrades humic acids in landfill leachate and pharmaceutical residues in municipal wastewater, improving effluent quality to meet Surface Water Class IV standards.

4. Medical and Pharmaceutical Industries

- Antibiotic Wastewater: Efficiently degrades hard-to-biodegrade organic matter, improving biodegradability (B/C ratio increased from 0.1 to 0.4).
