FEASIBILITY OF SOILIFICATION OF PHOSPHOGYPSUM DEALKALIZED RED MUD BY APPLYING FULVIC ACID

Faculty of Geosciences and Environmental Engineering, Southwest Jiaotong University, Chengdu 611756, China

摘要

摘要: 黄腐酸呈酸性,含有丰富的营养成分,是一种植物调节剂且能促进植物生长。为研究黄腐酸用于磷石膏脱碱赤泥土壤化的可行性,通过磷石膏脱碱赤泥试验与磷石膏-黄腐酸联合脱碱赤泥试验,对脱碱液和脱碱渣进行理化性质测定,并进行盆栽试验分析验证其可行性。结果表明:1)磷石膏脱碱可使赤泥的pH值由初始的11.08降低到9.00左右,而使用磷石膏-黄腐酸联合脱碱,可使赤泥的pH值降至8.50左右;2)分析结果表明,黄腐酸的加入促进了赤泥大粒径团聚体的形成,增加了大粒径团聚体的含量,增强了团聚体的稳定性;3)脱碱渣及脱碱液的元素分析结果表明,黄腐酸的加入使得赤泥中残留的重金属离子和Na⁺含量增加;4)盆栽试验结果表明,较高的重金属离子和Na⁺浓度将黑麦草种子的萌芽时间推迟了4 d,发芽率降低了8%。将赤泥进行脱碱以及去除重金属离子,使磷石膏脱碱赤泥中相应离子含量更少,而黄腐酸的加入有利于磷石膏脱碱赤泥的土壤化。

Abstract: Fulvic acid is rich in nutrients.It is a plant regulator and can promote plant growth.In order to study the feasibility of soilification of phosphogypsum dealkalized red mud by applying fulvic acid,through the phosphogypsum dealkalized red mud test and the phosphogypsum-fulvic acid combined dealkalized red mud test,the physical and chemical properties of the dealkalized solution and the dealkalized residue were measured,and the pot experiment was carried out to verify its feasibility.The research results showed that:1) phosphogypsum dealkalization reduced the pH value of red mud from 11.08 to about 9.00,and the combined use of phosphogypsum and fulvic acid reduced the pH of red mud to about 8.50;2) the analysis results showed that the addition of fulvic acid promoted the formation of large-diameter agglomerates of red mud and increased the content of large-diameter aggregates and enhanced the stability of the aggregates;3) element analysis results of the dealkalized residue and dealkalized solution showed that the addition of fulvic acid increased the residual sodium ion content and sodium ions content on the red mud;4) pot experiment results showed that higher concentrations of heavy metal ions and sodium ions delayed the germination time of seeds by 4 days and reduced the germination rate of seeds by 8%.With effective dealkalizaton and stabilization of heavy metals in the red mud,the addition of fulvic acid would be beneficial to soil transformation of phosphogypsum dealkalized red mud.
