Our Intelligent Integrated Equipment for Micro-Channel Catalytic Oxidation revolutionizes wastewater treatment by combining cutting-edge micro-channel continuous flow application technology with efficient electrocatalytic oxidation. This ingeniously crafted system seamlessly integrates novel materials, innovative processes, and groundbreaking technologies into a unique and specialized apparatus. It achieves unparalleled high flux and rapid mass transfer between pollutant particles, ensuring exceptional time-space conversion with minimal energy consumption. In-situ production of potent oxidizing agents such as active hydrogen, active oxygen, and hydroxyl radicals within the microchannel enables the effective treatment of complex compounds. Even structurally resilient substances like benzene series, halogenated hydrocarbons, phenols, monocyclic and polycyclic aromatic hydrocarbons, heterocyclic hydrocarbons, and pyridines in concentrated membrane solutions are efficiently broken down and removed through catalytic oxidation. This ensures the thorough degradation of high-concentration, high-salt, and toxic organic pollutants in a remarkably short timeframe.
High-performance Titanium-Based Electrode
Titanium serves as the foundational material for both anode and cathode electrodes. Our anode's surface undergoes a meticulous, multi-step coating and baking process, featuring 16 layers of proprietary nano-coatings developed over many years. Each layer's unique processing method enhances electrocatalytic activity, acid-base stability, electrolytic oxidation resistance, and current efficiency. The microchannel's distributed electrode group design minimizes connector resistance, augments electrolysis efficiency, reduces energy usage, and requires zero maintenance. Furthermore, our groundbreaking composite coating structure, combining an active surface layer with the titanium base, extends the anode's lifespan to over five times the national standard for high-quality products.
Innovative Electrode Coating
At the core of our titanium-based anode is an advanced nano-coating formula. This coating incorporates high-entropy alloy nanoparticle materials derived from noble metal salt oxides like ruthenium, iridium, tantalum, rhodium, and palladium, enhanced with manganese and tin. The strong bond with the substrate prevents titanium electrode digestion. Nano-scale refined grain coating offers exceptional corrosion resistance and exposes more active electrode surface areas. In an electric field, the nano-coating rapidly transfers electrons, significantly boosting liquid phase mass transfer efficiency and processing power. It efficiently catalyzes the production of potent oxidizing agents (·OH, SO4.-, OCl-, etc.), facilitating oxidation reactions with pollutants throughout the microchannel space, representing a truly innovative electrode material.
Unique Microchannel Reactor
Our uniquely designed micro-channel reactor ensures dispersed continuous flow and comprehensive reaction of pollutant molecules with ·OH on the electrode surface. Achieving COD removal rates above 95%, its mass transfer efficiency is 10 to 100 times greater than traditional electrocatalytic oxidation tanks. The design prevents the attenuation of valuable oxidizing free radicals (·OH, ·O2-). Independent segment distribution of electrocatalytic plates enhances the density and efficiency of catalytic oxidation reactions, generating hydroxyl radicals over 1,000 times more potent than standard plates. Adjustable sewage flow rates (0 to 60m3/min) allow over 90% removal rates in minimal time. This microchannel reactor addresses traditional process challenges such as high energy consumption and costs, enhancing sewage treatment efficiency while reducing energy use by over 50%, offering economic, safe, and stable operation. Automated control systems facilitate data traceability and quality control.
