Applying colmation layers in river banks and onto lake bed of water bodies in combination with inlake treatment of acidic and/or potentially acidic water, by applying and/or introducing lime- and dolomite products on and/or into water body

摘要

The method for applying colmation layers in river banks and onto a lake bed of water bodies in combination with an inlake treatment of acidic and/or potentially acidic water by introducing alkaline substances such as burned and unburned lime- and dolomite products, comprises repeatedly applying and/or introducing the burned and unburned lime- and dolomite products, which are introduced on lake surface and/or over the lake bed in powder form and/or in suspension concentration of 5-35% by using ship- and/or pipeline system and distribution technology, on and/or into the water body. The method for applying colmation layers in river banks and onto a lake bed of water bodies in combination with an inlake treatment of acidic and/or potentially acidic water by introducing alkaline substances such as burned and unburned lime- and dolomite products, comprises repeatedly applying and/or introducing the burned and unburned lime- and dolomite products, which are introduced on the lake surface and/or over the lake bed in powder form and/or in a suspension concentration of 5-35% by using ship pipeline system and/or pipeline system and distribution technology, on and/or into the water body by using the ship pipeline system and/or pipeline system. The grain distribution of the lime- and dolomite products with a total content of calcium oxide and calcium carbonate in the active substrate of greater than 70%, where the grain distribution is less than 5 mu m in the active substrate of 10%, is 5-50 mu m in the active substrate of 50%, is 51-100 mu m in the active substrate of 90% and is greater than 100 mu m in the active substrate of 10%. A potential alkalinity of 10-1000 mole-equivalent/m 2is adjusted at the water body with a specific overdosage. The lime- and dolomite products in the ingredient and/or in the ingredient mixture have a portion of greater than 5%. The ingredient concentration in dependent of the lake depth is adjusted to 1-15 mass% in less than 5 m lake depth and greater than 10 mass% in greater than 5 m lake depth related for the alkaline material to be introduced. The specific input quantity on the lake surface in dependent of the lake depth is repeatedly adjusted to 1-10 g/m 2in less than 5 m lake depth and 10-1000 g/m 2in greater than 5 m lake depth. The application of the colmation layer at the lake bottom repeatedly takes place by wind and/or thermally induced lake flows in the epilimnion. The lime- and dolomite products are hydrophobic. The hydrophobicity takes place with calcium- and/or magnesium stearate. The hydrophobic effect for the lime- and dolomite products is adjusted to a time of 5 minutes to 2 hours.
