Treatment of Dyes Wastewater by a New Kind of Bio - Fluid Bed

A new kind of bio - fluid bed used to treat dyes wastewater is described in detail due to its several special features, such as high removal efficiency, simple structure, shock load resistance, etc. By means of analyzing the experiment data, the results show that the dye wastewater's organic matter is removed greatly after being treated by this new kind of bio - fluid bed. On the other hand, the removal efficiency of chromaticity of the dye wastewater is from 96% to 100%, and that of its CODcr is almost 80% , while that of its BOD, is near to 90% . Furthermore, the reaction mechanism of this new kind of bio - fluid bed has also been studied briefly.
