METHOD FOR PRODUCING CONCENTRATED SOIL SOLUTION ENRICHED Russian patent published in 2019 - IPC C05F11/02 

FIELD: technological processes.

SUBSTANCE: method consists in creation of drainage system in isolated reservoirs. Eco-blackened eco-friendly horizontal layer is placed above it. Above it there is processed organomineral mixture mixed with ground combustible fossil in amount of up to 10 % of total volume of layer and with ground germs – carriers of required microflora, grown separately in amount of 1…2 % of total volume of layer. Above the organomineral mixture there is a layer of water-resistant mulch of thickness 2…5 mm. Maintaining temperature of 20–25 °C and relative humidity of more than 65 %. After completion of processing, the top wormsite layer is unloaded, and the lower layer is mixed with water of at least 2 volumes from the volume of the lower layer and supplied to a cavitator which grinds solid particles to a size of less than 1 mcm. From the cavitator the solution enters the settling vessel. After cooling down to 35 °C the solution is populated with soil microorganisms by adding a concentrated soil solution enriched in amount of 0.1–1 % of the volume of the solution in the settler. Resisted at temperature of 20–25 °C not less than a day. Drain through the tap located above the sediment level.

EFFECT: invention provides higher concentration of the solution.
