Photocatalytic Oxidation(PCO)Equipment is an advanced environmental purification device that utilizes photocatalytic technology to decompose harmful pollutants into non-toxic substances,widely applied in air and water treatment fields.Its core working principle relies on the synergy between a semiconductor photocatalyst(typically titanium dioxide,TiO₂)and ultraviolet(UV)light with a wavelength shorter than 380 nm.

When UV light irradiates the photocatalyst surface,it activates the catalyst to generate highly reactive hydroxyl radicals(·OH)and superoxide ions(O₂⁻).These oxidants can thoroughly break the chemical bonds of organic pollutants,volatile organic compounds(VOCs),bacteria,mold,and viruses,converting them into harmless carbon dioxide(CO₂)and water(H₂O)without producing secondary pollution.

The equipment is mainly composed of three key components:a high-efficiency UV light source,a recyclable photocatalyst carrier(such as honeycomb TiO₂plates),and an air or water circulation system.The UV light source ensures stable irradiation intensity to activate sufficient oxidants,while the porous carrier maximizes the contact area between pollutants and the catalyst,enhancing purification efficiency.

With remarkable advantages,PCO Equipment is energy-saving,requiring only electric power without additional chemical agents,and features low operating costs and a service life of over 15 years.It is widely used in indoor air purification,industrial wastewater treatment,industrial waste gas treatment,and food safety fields,effectively removing formaldehyde,benzene series,pesticides,and other hard-to-degrade pollutants.

As an eco-friendly purification solution,it operates at normal temperature and pressure,with no noise and simple automatic control,making it suitable for both industrial and civilian scenarios.It plays a crucial role in environmental protection and public health,providing a reliable way to improve air and water quality.
