Abstract
This paper presents the results of wastewater treatment at a mining enterprise developing a complex ore deposit in the Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this complex wastewater treatment, a two-stage scheme was proposed and tested using two sorbents (at a pH of 6): an aminated peat biosorbent to remove sulfate and a commercial sorbent based on the mineral brucite to remove metals. Optimal conditions were established for purifying the wastewater of sulfate and manganese and strontium ions to the level of maximum available concentrations in water bodies for fishery purposes.
Resumen
Este artículo presenta los resultados del tratamiento de las aguas residuales de una empresa minera que explota un yacimiento complejo en la región de Murmansk (Rusia). Los principales contaminantes son sulfato, manganeso y estroncio. Para el tratamiento de estas aguas residuales complejas, se propuso y probó un esquema en dos etapas utilizando dos sorbentes (a un pH de 6): un biosorbente de turba aminada para eliminar el sulfato y un sorbente comercial con base de mineral brucita para eliminar los metales. Se establecieron las condiciones óptimas para depurar las aguas residuales de sulfato y de iones de manganeso y estroncio hasta el nivel de concentraciones máximas disponibles en las masas de agua con fines pesqueros.
摘要
本文介绍了俄罗斯摩尔曼斯克地区一个开采复杂矿床的采矿企业废水处理结果。废水中的主要污染物为硫酸盐、锰和锶。针对如此复杂的废水处理,我们提出了一个两阶段的方案,并使用两种吸附剂(PH=6条件)进行了测试:用于去除硫酸盐的胺化泥炭生物吸附剂,以及用于去除金属的矿物水镁石商用吸附剂。此方法将废水中的硫酸盐、锰和锶离子净化,为该水体适用于渔业目的的最大允许浓度水平建立了最佳条件。
