Introduction

　　Multivariate and multiphase photocatalytic oxidation reactor is the newest product of Dalian Beida Purifying Equipment Co., Ltd in 2002. It adopts sunlight or ultraviolet to excite metal semiconductor to get many hydroxyls (-OH), which carry through multiple strong oxidation reaction with ozone and ultraviolet together.

Application area

　　It can be used as apparatus for scientific research and teaching in graduate school and universities, also environmental companies. It can be used to treat some wastewaters which having difficult degradation contaminants.

Product Character

● Multivariate:
　　1. It can use different oxidants, such as ozone (O3), hydrogen peroxide (H2O2), chlorine
　　　 dioxide (ClO2), etc.
　　2. It can utilize different lights, such as sunshine, ultraviolet, incandescent lamp, etc.
　　3. It can use different metal oxide semiconductor catalytic membrane, such as TiO2, ZnO, WO3,
　　　　etc.
　　4. It can use different electron acquirer. That is our exclusive design.
● Multiphase: gas, liquid and solid phase.
● Utility:
　　1. Chemical oxidation
　　2. Photo oxidation
　　3. Photochemical oxidation
　　4. Photocatalytic oxidation
　　5. Photochemical catalytic oxidation
● Durability: catalyst is plated on glass carrier as transparent membrane, which is
　 firmed, loss-free, long-term using.
● Mobility: it can be used in captive test, also in dynamic test.
● Electron acquirer: the electrons (e-) are acquired by it, which are excited from
　 metal semiconductor with holes (h+) at the same time. That can improve quantum
　 amount and oxidation speed of reaction.
● Simplification: in normal temperature and pressure, operation is easy and
　 manageable. And replacing membrane is convenient.
● Strong oxidizing property: it can degrade all organic contaminants (not including
　 suspended solid) in water, especially difficult biodegradation contaminants.
