摘要

The method for rehabilitation of standing water such as lake water by rottenness processes in a bottom sludge and normal turbid and evil-smelling surface water, comprises enlarging the surface of clay mixture through humidity and settling microorganisms on the surface. The clay mixture enriched with microorganisms is injected together with water in a desired ratio with pressure into the sludge and/or subjected on the water surface. A mixture of effective microorganisms and bentonite present in the liquid is produced over fermentation. The method for rehabilitation of standing water such as lake water by rottenness processes in a bottom sludge and normal turbid and evil-smelling surface water, comprises enlarging the surface of clay mixture through humidity and settling microorganisms on the surface. The clay mixture enriched with microorganisms is injected together with water in a desired ratio with pressure into the sludge and/or subjected on the water surface. A mixture of effective microorganisms and bentonite present in the liquid is produced over fermentation. The mixture sucked in and streaming out from the water is subjected in a given ratio. The supply of the mixture in the water flow is carried out by a venturi-nozzle (12, 13). The liquid is mixed with effective microorganisms and bentonite by a compulsory mixer. The bentonite is dosed by silos and mixed in the liquid. The mixture is brought together with the water flow by a sludge injector (16) under pressure in the sludge and the sludge is processed. The mixture subjected in the flowing surface water is distributed by an irrigation cannon on the water. The cleaning of the water is carried out by supplying the mixture by the sludge injector and subsequently cleaning of the water by the irrigation cannon. An independent claim is included for a device for rehabilitation of lake water by rottenness processes in bottom sludge and normal turbid and evil-smelling surface water.
