Aiming at the high organic substance problem in the make-up water of boilers in heat power plants, the process of ozone (O3)-biological activated carbon (BAC) is applied. The result shows that when the dosage of ozone is 3 mg/L,the contact time of ozone is 20 min and the retention time for BAC column is 20 min,the average removal rate of CODMn is 52.57% and the removal rate of UV254 is 68.15%. In the meantime,the effluent of the BAC column is stable and its lifetime is prolonged when the ozone is in coordination with BAC. The result shows that the process of 03-BAC is feasible in the application of make-up water treatment of boilers.
