Electrochemical Industrial Wastewater Treatment System
Our Electrochemical Industrial Wastewater Treatment System is a cutting-edge, environmentally friendly wastewater treatment solution specifically engineered to tackle the most challenging refractory industrial wastewater—a pain point that traditional treatment technologies (such as biological treatment, physical filtration, and chemical coagulation) often fail to address. By leveraging the power of in-situ generated strong oxidizing species (including hydroxyl radicals (•OH), active chlorine, and ozone), the system efficiently degrades high-toxicity, high-COD, non-biodegradable organic pollutants, heavy metal complexes, and persistent contaminants (such as PFAS, pesticides, and pharmaceuticals) into harmless CO₂, H₂O, and inorganic salts. It ensures stable compliance with global strict environmental emission standards, including EU, US EPA, and regional regulations, providing a reliable and cost-effective solution for enterprises struggling with refractory wastewater treatment.

Product Feature
Core Working Principle
Our EAOP system integrates advanced electrochemical oxidation technology, utilizing high-performance electrodes and intelligent power supply control to realize efficient and thorough degradation of refractory pollutants through dual oxidation mechanisms (direct oxidation and mediated oxidation), with a streamlined and stable operation process:
1、Electrode Reaction & Oxidant Generation: The system consists of high-performance anode and cathode electrodes, connected to an intelligent power supply. When voltage is applied, electrochemical reactions occur at the electrode surfaces: the anode generates highly reactive hydroxyl radicals (•OH) with a high standard reduction potential (E° = 2.80 V vs SHE) through water oxidation, while the cathode promotes the generation of hydrogen peroxide (H₂O₂)—both are powerful oxidizing agents that can break down refractory organic pollutants. Additionally, chloride ions (common in most wastewater) are converted into active chlorine species (such as hypochlorite) through mediated oxidation, further enhancing the degradation effect.
2、Dual Oxidation Degradation: The refractory pollutants in wastewater are degraded through two synergistic pathways: direct oxidation, where pollutants are directly oxidized and decomposed by electrons at the anode surface; and indirect oxidation, where strong oxidizing species (•OH, active chlorine, H₂O₂) generated in-situ react with pollutants in the entire water body, breaking their chemical bonds and converting them into small-molecule intermediates, which are ultimately mineralized into harmless CO₂ and H₂O. This dual mechanism ensures thorough degradation of even the most stable non-biodegradable contaminants, including aromatics, dyes, and pharmaceuticals.
3、Post-Treatment & Water Reuse: After electrochemical oxidation, the treated wastewater undergoes simple sedimentation and filtration to remove small amounts of inorganic precipitates. The effluent meets emission standards or can be further treated for reuse, realizing water resource recycling. The system is equipped with automatic electrode cleaning and anti-scaling functions, which effectively prevent electrode fouling and ensure long-term stable operation. For high-salt refractory wastewater, the system can be coupled with other technologies (such as electrocoagulation or membrane separation) to further optimize treatment efficiency and reduce operating costs.
Key Product Advantages
1、Superior Refractory Treatment Capacity: Specialized in handling high-difficulty wastewater, including high-COD (COD ≥ 5000mg/L), high-toxicity, non-biodegradable, high-salt (TDS ≥ 10000mg/L), and heavy metal-containing wastewater. The COD removal rate reaches 70–95%, and the mineralization rate of organic pollutants is up to 97%, effectively degrading PFAS, antibiotics, and other persistent contaminants that traditional technologies cannot handle.
2、Chemical-Free & Zero Secondary Pollution: The entire treatment process relies on in-situ generated oxidizing species, without adding external chemical agents (such as oxidants, flocculants, or neutralizers), avoiding secondary pollution caused by chemical residues or sludge production. The treated wastewater and by-products are non-toxic and harmless, fully complying with global environmental protection requirements.
3、High-Performance Electrode Materials: Adopts high-quality non-active anode materials, including boron-doped diamond (BDD), SnO₂-Sb, and iridium-doped titanium oxide composite electrodes, which have high oxygen evolution potential, strong corrosion resistance, and long service life (≥5 years). The electrodes effectively stabilize hydroxyl radicals and enhance oxidation efficiency, even in high-acid, high-alkali, and high-salt environments.
4、Energy-Saving & Cost-Effective: Operates at ambient temperature and pressure, with low energy consumption (0.5–10 kWh/m³ depending on wastewater quality). Equipped with an efficient energy recovery device and intelligent power adjustment system, it reduces energy consumption by 20–30% compared with traditional advanced oxidation technologies. The simple structure, low failure rate, and automatic cleaning function also reduce maintenance costs and manual management costs.
5、Stable & Reliable Operation: Adopts a modular design and micro-negative pressure operation, with strong anti-impact load capacity, adapting to large fluctuations in wastewater flow and pollutant concentration. Multiple safety interlock protection systems (over-temperature alarm, over-current protection, leakage detection, and short-circuit protection) are equipped to effectively prevent operational risks, ensuring 24-hour continuous stable operation.
6、Compact & Easy Installation: Modular integrated design, small footprint (30–50% smaller than traditional advanced oxidation equipment), easy to install, disassemble, and expand. It can be prefabricated in the factory and quickly assembled on site, shortening the construction and commissioning cycle, suitable for both new projects and old factory renovation—especially ideal for projects with limited space.
7、Intelligent & Automatic Control: Equipped with a PLC intelligent control system, it can realize automatic voltage/current adjustment, automatic electrode cleaning, automatic water intake and discharge, remote monitoring, and fault alarm. It supports 24-hour unattended operation, reducing manual intervention and ensuring stable treatment effect and operational parameters.
8、Strong Adaptability & Versatility: Can handle various types of refractory wastewater from different industries, including high-salt, high-acid, high-alkali, and toxic wastewater. It can be used as a pre-treatment unit for biological treatment (improving biodegradability of wastewater) or as a deep treatment unit for advanced purification, and can be coupled with other technologies to meet diverse treatment needs.
9、Global Compliance: The design fully complies with international environmental standards and industry norms, including EU and US EPA regulations. We can provide customized solutions according to the emission requirements of different countries and regions, helping customers smoothly pass environmental inspections and avoid environmental penalties. Our products are exported to dozens of countries and regions, adapting to the stringent environmental standards of mature markets and the growing demand of emerging economies.
