Purpose of the development: Securing of slopes and beaches sludge storage using biological materials - blocks of turf and reed mats.

Recommended application field: Storage and disposal of waste iron and steel industry in open sludge ponds, as well as concentrating, smelting, chemical and rudopererabatyvayuschih enterprises (uranium, mining plants, alumina plants, waste storage, thermal power plant, power plant, nuclear power plants, ports).

Advantages over analogues: Implementation features of the invention achieves the advantages that can not be achieved at the closest analogue of the method, namely, the claimed method involves the use of biological systems for suppressing the formation of dust, which is more environmentally safe; In addition, the inventive method is effective, as evidenced by the values of the coefficient of resuspension of dust; the proposed method enables the use of sludge storage products, if necessary, without destruction of the protective layer.

The development stage readiness: Ready for application

Technical and economic effect: The low cost of biological material, its transportation, long-term protective effect of his proposed method makes economically attractive.

Description of the development:
()
A method of suppressing dust and fixing surface of red mud sludge storage, which includes sludge storage surface irrigation aqueous sulfuric acid with a concentration of 5.0 g / l, at a rate of - 1 m solution on the surface of 0.2 ha. Thereafter, the treated surface is carried sodding prestaged turf layer thickness of 5-7 cm on the basis of vegetation, comprising 4-6 components from cereal family, Convolvulaceae, clove and at least one component of the legume family. The method additionally provides for the use of reed mats thickness of 3-5 cm. The proposed method is applied for dust suppression sludge storage number 1 Nikolaev alumina refinery. Field and laboratory studies have shown sufficient resistance to the action proposed materials harmful factors (pH 10-11) and weather conditions (t: from - 20 to + 40 ° C, snow, rain, wind), that is shown on the suitability and effectiveness of the consolidation of the surface sludge storage.
