Therefore, the scientific research workers research and development of various aniline degradation in the environment of aniline degradation method of substances, To satisfy the environmental protection request. This experiment degradation of pollutants aniline degradation part factors influence are discussed in water with ultrasonic. Experiments show that: Temperature is 25 ℃, the initial concentration of 0.2 ug/L, degradation time when 7min for 33.8% for removal. Simultaneo us determination of COD degrading simulation wastewater before removal under the same conditions for 33.8%.
