The combined process of micro-aerobic aeration,aerobic aeration,coagulation sedimentation,oxygen-rich biological activated carbon and UV disinfection was used to treat wastewater from DME production.

Pressurized reactor-biological activated carbon (PRBAC) process, a new development based on conventional biological activated carbon (BAC) process, is more effective for pollutant removal by way of stronger biological activity strengthened by increased DO level inside the activated carbon column at pressured state.

Determination for Optimal Ozone Dose in O_3-BAC;

Application of ozone-biological activated carbon(O_3-BAC)process in drinking water plant;

Advanced treatment process such as suspended carrier biological oxidation,flocculation and sand filtration,aerated biological activated carbon,and chlorine disinfection process was used for treatment of oil refinery wastewater with a capacity of 7 000～8 000 m~3/d.

Aimed at the microbial safety of ozone/biological activated carbon(O3/BAC) process,through the pilot-scale and productive experiments,a systematic evaluation was carried out considering the aspects of pathogenic microorganisms,microbial population,turbidity,particle number and AOC.

The O3/BAC process was applied in the pilot-scale advanced treatment of Miyun Re-(servoir) water.

However,the removal rate of DON by O3/BAC can reach 60%.

The experimental data from the treatment of micro-polluted water by O3-BAC process of a pilot test showed that the effluent could reach the standard of drinking water stipulated by our country;the average value of CODMn in BAC filtration effluent was 1.
