The invention relates to a method for destroying
tetrahydrocannabinol (THC), in particular to a method and a
system for destroying
tetrahydrocannabinol based on photocatalytic oxidation. According to the invention, nano
titanium dioxide (TiO2) is used as a catalyst,
active oxygen free radicals are generated under the excitation of
ultraviolet rays with specific
wavelength, and the THC molecular structure is decomposed. The multi-stage
reaction system is adopted,
raw material pretreatment,
solvent dissolution and dispersion,
photocatalytic degradation reaction and
tail gas purification modules are integrated,
tetrahydrocannabinol is decomposed on a
production line, the supervision pressure in production is relieved, the degradation rate of tetrahydrocannabinol reaches 99% or above, degradation products are
carbon dioxide, water and trace
inert organic acid, and high efficiency and environment friendliness are achieved. The method is suitable for innocent treatment of hemp
processing waste, law
enforcement inspection products or
medical waste, and is simple to operate, high in practicability and suitable for industrial popularization and application.
