Study on degradation of direct reddish brown M by RuO_2/ La_2O_3/ TiO_2 coupled photocatalyst RuO2/La2O3/TiO2复合光催化剂对直接红棕M的降解研究
Adsorption of Direct Dark Brown M and Acid Mordant Brown RH dyes in water by dried activated sludge, pyrolysis activated sludge and modified activated sludge, which made from the material of discarded activated sludge of municipal wastewater treatment plant, was studied. 以城市污水处理厂剩余活性污泥为原料,制取干污泥、热解污泥和改性污泥作为吸附剂,对直接深棕M和酸性媒介棕RH等染料进行了吸附试验研究。
The adsorption of dye direct dark brown M on dried activated sludge fitted Freundlich isotherm model and the dye can be easily adsorbed by modified activated sludge and pyrolysis activated sludge. 直接深棕M的吸附符合Freundlich型等温吸附,易于吸附在改性污泥和热解污泥上;
