Our intelligent, integrated equipment for micro-channel catalytic oxidation represents the pinnacle of innovation in wastewater treatment. Combining cutting-edge micro-channel continuous flow application technology with advanced electrocatalytic oxidation, this system is meticulously designed to amalgamate new materials, processes, and technologies into unique, specialized equipment. It ensures high flux and rapid mass transfer between pollutant particles, maximizing time and spatial conversion with minimal energy consumption. In situ, within the microchannel, powerful oxidizing agents like active hydrogen, active oxygen, and active hydroxyl radicals are generated, enabling the effective catalytic oxidation of complex components such as structurally resilient benzene series, halogenated hydrocarbons, phenols, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, heterocyclic hydrocarbons, and pyridines. This process ensures the comprehensive degradation of high concentration, high salt, and toxic organic pollutants in an extraordinarily short time, achieving unparalleled ring breaking and chain removal.
High-Performance Titanium-Based Electrode
Crafted using premium titanium as the base material for both anode and cathode electrodes, our product undergoes a series of specialized precision processes. The anode is coated and baked with 16 innovative nano-coatings developed over the years, each layer meticulously applied for enhanced electrocatalytic activity, superior acid-base stability, and exceptional electrolytic oxidation resistance. Our distributed electrode group design within the microchannel not only minimizes connector resistance but also boosts electrolysis efficiency, lowers energy consumption, and ensures maintenance-free operation. Additionally, the advanced composite coating structure merging the surface active layer with the titanium base significantly extends the anode's lifespan, exceeding national standards by fivefold.
Innovative Electrode Coating
Our titanium-based anode boasts an advanced nano-coating formula enriched with high-entropy alloy nanoparticle materials derived from noble metal salt oxides like ruthenium, iridium, tantalum, rhodium, and palladium, along with elements such as manganese and tin. This precise combination ensures excellent adherence to the substrate, preventing titanium electrode degradation. The nano-scale grain coating offers robust corrosion resistance and, due to its size, allows for greater exposure of electrode surface active areas. Under an electric field, the nano-coating facilitates rapid electron transfer, significantly enhancing liquid phase mass transfer efficiency and processing speed. This results in the quick generation of potent oxidizing agents (·OH, SO4.-, OCl-, etc.), which interact with pollutants throughout the microchannel space, showcasing a truly groundbreaking electrode material.
Unique Microchannel Reactor
Our uniquely refined microchannel design ensures the dispersed continuous flow of membrane concentrate and comprehensive interaction between polluted molecules and the electrode surface's ·OH. Achieving a COD removal rate exceeding 95%, our system's mass transfer efficiency is 10 to 100 times that of traditional electrocatalytic oxidation tanks. The microchannel design mitigates the loss of valuable oxidizing free radicals (·OH, ·O2-), enabling independent segment distribution of electrocatalytic plates, significantly boosting the spatial catalytic oxidation reaction density and efficiency. Capable of controlling sewage flow rates from 0 to 60m3/min, our system ensures a removal rate above 90% in minimal time. This innovative reactor addresses the high energy consumption and costs associated with traditional electrocatalytic processes, enhancing sewage treatment efficiency, reducing energy consumption by over 50%, and offering multiple advantages such as economic viability, safety, and stability. Moreover, automated control facilitates data traceability and quality management.
