摘要：

An ozonation technology to treat lightly loaded effluents from dye manufacturing processes has been developed. The process uses air-generated ozone and countercurrent contactors. An intermediate step is included to eliminate OH-radical scavengers and slowly reacting oxidized species from the liquid phase. A study of ozone efficiency and yield concerning the reduction of TOC and COD levels is presented. The biological degradability of treated water is discussed. A design and rating calculation procedure for countercurrent contactors is presented. Various waste treatment strategies using separation processes and ozone are discussed briefly. A cost estimate to treat a typical dye effluent in two stages on industrial scale is included.
