The photocatalyst converts light energy into energy of chemical reaction to generate catalytic action, so that surrounding water molecules and oxygen are excited into hydroxyl free radicals and superoxide ion free radicals with strong oxidizing power, organic substances and partial inorganic substances harmful to human bodies and the environment can be decomposed, the reaction is accelerated, no resource waste is caused, and no new pollution product is formed.

⑤ catalytic reaction process is that ⑤ reactant reacts around ⑤ catalyst and ⑤ peripheral reactant diffuses toward ⑤ catalyst continuously, and ⑤ product diffuses toward ⑤ catalyst continuously, and includes seven steps of ① raw material molecules from ⑤ main airflow to ⑤ inner surface of ⑤ micropores, adsorption of material molecules near ⑤ surface of ⑤ catalyst by ⑤ catalyst, chemical reaction of ⑤ adsorbed molecules under ⑤ action of ⑤ catalyst, desorption of ⑤ product molecules from ⑤ catalyst, diffusion of ⑤ desorbed product molecules from ⑤ micropores, diffusion of ⑤ product molecules from ⑤ outer surface of ⑤ catalyst to ⑤ main airflow and separation from ⑤ reactor.
