Catalytic wet oxidation of high concentration pharmaceutical wastewater with Fe3+ as catalyst

Non-Catalytic Subcritical Wet Oxidation of a Wastewater Treatment Sludge

Among the treatment and conversion technologies used for organic solid waste, wet oxidation has become an important process due to the fascinating characteristics of water as a reaction medium at elevated temperatures and pressure. Wet oxidation is able to degrade and remove organic compounds and thus reduce the mass and volume of solid wastes. Recovering valuable compounds and enhancement of a...

Research on Catalytic Oxidation Pretreatment of Organic Pesticide Wastewater with High Concentration

Pesticide wastewater has the characteristics of high organic pollutant, high concentration, deep color and high toxicity, which has become difficult to treat the organic wastewater with high concentration at home and abroad. This article uses three methods of US(ultrasonic), Fenton(Fe&H2O2) and combination of US&Fenton were used in the comparative research on the treatment of organic pesticide ...

Wet air oxidation of phenol using active carbon as catalyst

Catalytic wet air oxidation is a promising alternative for the treatment of phenolic waste water which cannot be treated in conventional sewage plants. Catalytic wet air oxidation of an aqueous phenol solution was conducted in a ®xed bed reactor operating in trickle ̄ow regime. Either active carbon or a commercial copper oxide supported over -alumina was used as catalyst. The performance of bot...

Catalytic Wet Oxidation of Ammonia Solution with Platinum- Palladium-rhodium Composite Oxide Catalyst

This study adopted high concentration aqueous solutions of ammonia for use in catalytic liquid-phase oxidation in a trickle-bed reactor with platinum-group metals (platinum-palladiumrhodium), prepared by the co-precipitation of H2PtCl6, Pd(NO3)3 and Rh(NO3)3. The experimental results revealed that a minimal amount of ammonia was removed from the solution by wet oxidation in the absence of any c...
