METHOD TO PREVENT FILTRATION OF CONTAMINATED HIGH-MINERALISED INDUSTRIAL WASTES INTO WATER-BEARING HORIZON OF UNDERGROUND WATER AND ANTI-FILTRATION ACCUMULATOR Russian patent published in 2013 - IPC E02B3/16 

FIELD: construction.

SUBSTANCE: method consists in maintenance of the level of industrial wastes within the circuit of the anti-filtration accumulator. For this purpose they previously detect density of high-mineralised industrial wastes and density of edge underground water. The distance is identified from the specified point of the bed to the arbitrarily chosen plane of comparison. The maximum permissible drop is defined between them, as well as water density in the specified point of the bed and the arbitrarily chosen plane of comparison. Maintenance of the level of high-mineralised industrial wastes in the anti-filtration accumulator is performed below the natural level of the edge underground (soil) water, and it is monitored by the value of the "given" pressure of the liquid phase of industrial wastes, and using the ratio P_giv = hγ+z(γ+γ₀)/2, where P_giv - given pressure of liquid phase of industrial wastes, M·L^-1·T^-2; h - hydrostatic height (level) of liquid industrial wastes of heterogeneous composition in the accumulator bowl, L; z - distance from the specified point of the bed to the arbitrarily chosen plane of comparison, L; γ and γ₀ - volume weight of water in the specified point and on the arbitrarily chosen plane of comparison, M·L^-2·T^-2. The anti-filtration accumulator for implementation of the method comprises a bowl, an anti-filtration screen, arranged on the bottom of the accumulator and in boards of the bowl, and a water-regulating systems from water-regulating wells. Additionally inside the bowl there are water-distributing wells, which are connected with a water-regulating device and a system of horizontal pipes.

EFFECT: higher reliability of protection against pollution of underground water with brines filtered from an accumulator and other liquid wastes of industrial production that are dangerous for human livelihood, possibility is provided for environmental stability of compositions available in a liquid wastes or brines accumulator and their finalisation to the appropriate technologically stable condition.
