Abstract
1. Способ нейтрализации кислых сульфатсодержащих сточных вод, включающий нейтрализацию известковым молоком, осаждение взвешенных частиц в присутствии анионного флокулянта и пиритных отвальных хвостов горно-обогатительного производства, содержащих железо и серу, перемешивание и отстаивание, отличающийся тем, что полученную воду разделяют на два потока, один из которых направляют на доочистку перед сбросом в водные объекты, а другой направляют на орошение отвалов для частичной нейтрализации подотвальных вод, образуя поток рециркуляции. ! 2. Способ по п.1, отличающийся тем, что степень рециркуляции воды, используемой для орошения отвалов, составляет 20-30%. 1. A method of neutralizing acidic sulfate-containing wastewater, including neutralization with milk of lime, precipitation of suspended particles in the presence of anionic flocculant and pyrite dump tailings of mining and processing plants containing iron and sulfur, mixing and settling, characterized in that the resulting water is divided into two streams, one of which is sent for post-treatment before discharge into water bodies, and the other is sent for irrigation of dumps for partial neutralization of subsurface waters, forming a recirculation stream . ! 2. The method according to claim 1, characterized in that the degree of recirculation of water used for irrigation of dumps is 20-30%.
