Since the late 20th century, there have been many warnings
about the existence of phenol and phenol compounds in the
environment, especially the water environment. Phenol pollutes the
natural water environment due to its presence in many industrial waste
streams such as petrochemical, coke, steel . [1-3]. Although widely
used in many industries, science has proved that phenols are toxic to
humans and organisms. Thus, phenol pollution in water is becoming a
serious problem for many countries, including Vietnam. Many methods
have been applied to treat phenol in water such as adsorption, biology,
catalytic wet oxidation . However, it is often necessary to combine two
or more technologies to completely remove phenol from the waste
stream. Recently, catalytic Ozonation Process (COP) or catazon has
emerged as a new strategy for the treatment of persistent organic
substances and has proven very effective in treating wastewater.
contains phenol compounds. This method has many advantages such as
no problems related to chemicals, high efficiency of pollutant
decomposition, fast processing time, simple equipment, easy to install,
no waste sludge and In particular, ozone can be
