Ozone Catalytic Oxidation Technology
Ozone catalytic oxidation technology is applied to industrial wastewater treatment in coal chemical, steel, municipal, textile and other industries. Carbon-based and metal-based porous composite catalysts are developed targeting heterocyclic, polycyclic, phenolic and other organic pollutants in wastewater. Active metals are anchored via strong covalent bonds between nitrogen and metals, and a micro-oxygen solid-solution preparation technology is adopted to improve catalyst stability.
With a small dosage of ozone as oxidant, under the effect of high-efficiency special KI-CO3 and KI-CO4 catalysts, refractory organics can be selectively oxidized and decomposed under neutral conditions. Treated wastewater can meet the national new standard for direct discharge in terms of COD, chroma, benzo[a]pyrene and other indicators.
Equipment Development
Proprietary core equipment for heterogeneous catalytic ozonation is developed based on the quantitative prediction model of mass transfer-reaction coupling. Multiple degradation pathways can be simulated according to different wastewater sources to reduce ineffective ozone decomposition and strengthen effective reactions.
