Process and development of ozone-biological activated carbon treatment for micro-polluted raw water

The basic principle and process flow of ozone-biological activated carbon treatment of micro-polluted source water were analyzed, and the application of the method at home and abroad was introduced. Some problems that need to be paid attention to when applying the method were put forward. The results show that ozone-activated carbon water purification technology can effectively remove organic matter and ammonia nitrogen in water. It also has good removal effect on inorganic reducing substances, chroma and turbidity in water. Moreover, the mutagenic activity of effluent can be effectively reduced to ensure the safety of drinking water. Some problems which should be attended are prompted when this technique is in application in the paper. It is a water purification technology worth promoting. (paper)
