This article introduced character of ozone and mechanism of ozonization.

In order to improve biodegradability and decrease COD of the pharmaceutical wastewater, Ozonization process was adopted.

In response to the characteristics of wastewater from the processing of pharmaceutical intermediate, A~2O process was used for biochemical treatment after the pretreatment by the metal exchange bed for copper removal / ozonization pretreatment process.

Advanced treatment of sewage secondary effluent by preozonation/biological aerated filter(BAF);

The objective was to determine: the contribution of algae cells and algae extracellular organic matter(EOM) to the disinfection by-products formation potential(DBPFP),and the effects of preozonation including ozone dosage and preozonation time on DBPFP of algae cells and EOM and mechanism of these effects.

Experiments were conducted with preozonation-floating filter and ozone-DAF-floating filter for treatment of water from Queshan Reservoir.
