The main mechanism of photochemicaloxidation includes receiving sunlight energy, combining dissolved oxygen in different manner, and then degrading oil hydrocarbons.
光化学氧化机理主要在于接受日光照射的能量，以不同的方式与溶解氧结合，从而最终降解石油烃。

Furthermore, the thesis was discussed primarily the degradation principle of sulfide and mechanism of chemical catalytic oxidation on sulfide and photochemicaloxidation on organic mechanism.
此外，本文对化学催化氧化法转化硫化物的规律和机理，及光化学氧化法降解有机物的机理进行了初步探讨。
