COD Removal of Washing Water by Photodegradation

摘要：

　　Degradation of the wastewater of washing oil tanks after degreasing and minimal treatment by photocatalysis is studied by using a rotating photoreactor and TiO2 photocatalyst of Degussa P25.Effects of irradiation time and pH value on removing efficiency are investigated.The results show that the COD down to about 80mg/L can be achieved at the irradiation time of about 4-5 hours at mild pH valus.At the pH value from 1.5 to 3.2,the COD down to about 80mg/L can be achieved at the irradiation time less than 1 hour,and the COD down to about 20mg/L could be achieved at the irradiation time of about 4 hours at a pH value of about 3.2.
