Introduction

Modern waste management faces numerous challenges, demanding innovative technologies to address environmental concerns and improve efficiency. Incineration remains a vital waste management option, but traditional approaches need to be enhanced to minimize emissions and maximize energy recovery. Advanced oxidation technologies offer significant potential to elevate the efficiency and sustainability of incinerators.

Advanced Oxidation Technologies

Advanced oxidation technologies employ high-temperature oxidation processes to enhance the completeness of combustion and eliminate harmful pollutants. These technologies utilize various catalysts and reactor configurations to facilitate efficient oxidation reactions.

1. Selective Catalytic Oxidation (SCO)

• Uses noble metal catalysts to selectively oxidize specific pollutants like dioxins and furans.
• Reduces emissions of regulated organic compounds (ROCs) by 99.99%.

2. Fluidized Bed Oxidation (FBO)

• Employs a fluidized bed of inert material to enhance heat transfer and promote oxidation.
• Suitable for treating a wide range of waste types.

3. Plasma Oxidation

• Uses electrical energy to generate high-temperature plasma.
• Offers complete oxidation of pollutants and energy recovery.

4 vicissidation

• Injects oxygen and/or air into the combustion chamber to enhance oxidation.
• Can significantly reduce emissions of NOx and SOx.

4 vicissidation with activated carbon

• Utilizes activated carbon to absorb pollutants and then oxidizes the adsorbed contaminants.
• Provides high efficiency for removing a variety of pollutants.

Benefits of Advanced Oxidation Technologies

• Reduced emissions of harmful pollutants.
