铁铝酸四钙对矿井水中SO_4^(2-)的去除研究

Study on Removal of Sulfate Ions from Mine Water by Brownmillerite

针对山西省煤矿矿井水的水质特性,研究通过混凝吸附作用对矿井水中SO42-的去除效果,通过实验,发现在pH=7～9时,采用Ca(OH)2+铁铝酸四钙(4CaO·Al2O3·Fe2O3)+少量PAM的药剂投加方式,对矿井水中降低SO42-效果较好。

According to the water quality characteristics of mine water in Shanxi Province, this paper studies the removal effect of sulfate ions by coagulative adsorption of mine water.Experimental results show that the dosage of Ca（ OH ）2＋ Brownmillerite ＋ little PAM has good removal effect of sulfate ions when pH value is at 7-9.
