摘要
对用硫铁矿烧渣制备无机复合混凝剂聚合铁盐进行了试验研究 ,考察了影响烧渣酸溶和铁聚合的因素。结果表明 ,硫酸浓度、反应时间和体系温度等是影响硫铁矿烧渣中铁溶出率的主要因素 ,在烧渣酸溶过程中添加适当的助溶剂 ,不仅能够加快酸浸速度 ,而且还可以提高产品的混凝性能。
s:The preparation of inorganic composite coagulant polymeric iron was studied.Some factors affecting the stripping rate of ferric sulfide dregs and polymerization were investigated.Experimental results show that sulfuric acid concentration,reaction time and temperature were main factors affecting the stripping rate.In the dissolution process of ferric sulfide dregs,the adding of suitable lacquer solvent could make not only the iron stripping rate accelerate,but also the coagulate ability reinforced.
