Abstract

"IMOBILIZAçãO IN SITU DENTRO DE CORPOS DE áGUA DE DENSIDADES VARIáVEIS". é descrito um método para o tratamento (in situ) de grandes corpos de água contaminados com metais pesados e tendo camadas de densidades variadas para imobilizar os metais contaminantes. O método, ou o processo para a imobilização (in situ) dos metais está focado no tratamento de grandes corpos de água tendo metais nas mesmas que são também adjacentes a uma margem de solo ou materiais da terra em uma tentativa de imobilizar os metais de penetrar através do solo. O método é também capaz de tratar a divisa de água do solo dentro da lagoa de mina para proporcionar imobilização adicional. As lagoas de minas podem incluir as lagoas de minas abertas, as lagoas de minas subterrâneas, as correntes de escoamento e similares. O método é também capaz de tratar uma mina abandonada antes do enchimento da mina com água. Inicialmente, é determinada a média de densidade do corpo de água, o qual é o mais denso, típico em regiões a ou aproximando 4 graus C. O processo inclui introduzir uma substância de tratamento que tenha uma densidade maior do que aquela da média de densidade no corpo de água, proporcionando pelo menos um micróbio próximo ao ou no corpo de água, produzindo sulfetos microbianos que surgem da colocação inicial de micróbio, fazendo com que os sulfetos microbianos reajam (in situ) com os íons de metais ou os compostos contendo metais localizados dentro do corpo de água, reduzindo a solubilidade dos íons de metais por formação de sulfetos de metais, e inibindo a taxa de migração dos íons de metais ou outros compostos contendo metais dentro ou a partir dos solos ou materiais da terra à medida que eles precipitam da água."IN SITU IMMOBILIZATION WITHIN VARIABLE DENSITY WATER BODIES". A method for treating (in situ) large bodies of water contaminated with heavy metals and having layers of varying densities to immobilize the contaminating metals is described. The method or process for in situ immobilization of metals is focused on treating large bodies of water having metals thereon which are also adjacent to a soil margin or earth materials in an attempt to immobilize the metals from penetrating through the ground. The method is also capable of treating the soil water boundary within the mine pond to provide additional immobilization. Mine ponds may include open mine ponds, underground mine ponds, runoff streams and the like. The method is also capable of treating an abandoned mine prior to filling the mine with water. Initially, the average density of the body of water is determined, which is the densest, typical in regions at or near 4 degrees C. The process includes introducing a treatment substance that has a density greater than that of the average density. in the body of water, providing at least one microbe close to or in the body of water, producing microbial sulfides that arise from initial microbe placement, causing microbial sulfides to react (in situ) with metal ions or metal-containing compounds. located within the body of water, reducing the solubility of metal ions by formation of metal sulfides, and inhibiting the migration rate of metal ions or other metal-containing compounds within or from soil or soil materials as they occur. precipitate from the water.
