摘　　要：进行了铝土矿中有机物黑腐酸对赤泥沉降性能影响的研究。考查了不同浓度条件下黑腐酸对赤泥沉降速度、溢流浮游物含量和底流压缩液固比的影响,探讨了絮凝剂消除黑腐酸负面作用的条件。It was studied the effects of the fulvic acid on properties of the mud sedimentation in bauxite. The effects of different concentration of fulvic acid on settlement rate, overflow clarity and download L/S were studied. Elimination of the negative effect of flocculate on the fulvic acid was also studied in this paper.
