摘要/Abstract

摘要： 为探寻引滦输水河道尾矿砂、上覆水、沉积物磷之间的平衡特性关系,在室内分别进行了磷释放批量平衡试验、静态模拟试验和动态模拟试验。结果表明：3种不同尾矿砂用量振荡7 d,对上覆水PO₄-P去除率均在90％以上,效果明显;在厌氧和碱性pH值等外界环境因素的影响作用下,尾矿砂无法抑制沉积物中的生物可利用磷解吸进入上覆水体中,上覆水中的磷酸盐浓度呈现显著升高的态势;磷在强酸、强碱范围内释放量较高,而在中性条件下释放量最小。

Abstract: To study the phosphorus balance characteristics between mine tailings soil, overlying water and the sediments, phosphorus release experiment, static simulation experiment and dynamic simulation experiment were done in the lab. The results show that releases of phosphorus in the mine tailings sand is small. Three different amount of mine tailings soil of oscillation 7 days can remove PO₄-P in the overlying water more than 90％and the effect is obvious. With the influence of the environment factors of anaerobic and alkaline, mine tailings soil can not inhibit the biological available phosphorus in sediment into the overlying water. The concentration of phosphate in the overlying water increase significantly. The amount of Phosphorus release is larger in acid and alkali. The amount of Phosphorus release is minimal in neutral.

Key words: Luanhe river, mine tailings soil, overlying water, sediment, balance
