AI Technical Summary
Existing heterogeneous catalytic oxidation systems suffer from problems such as large footprint, high investment, low pollutant degradation efficiency, high operating costs, and catalyst caking.
A novel, enhanced circulating heterogeneous Fenton catalytic oxidation system is designed, comprising a pretreatment unit, a catalytic oxidation reaction unit, and a coagulation and sedimentation unit. An internal circulation is constructed using a multi-layer packing layer, an inner cylinder, and a baffle plate. Combined with an inert ceramic ball layer, a solid waste-based catalyst is employed, and the structure of the catalytic oxidation reaction tower is optimized to achieve catalyst stability and high efficiency.
It effectively reduced operating costs, improved pollutant degradation efficiency, reduced iron sludge production, enhanced catalyst structural stability and resistance to water impact, and reduced land occupation.
