A method for improving water quality of the open or acidic sulfate-containing waters

摘要

A method for improving water quality of the open or acidic sulfate-containing bodies of water with a lake volume of greater 500.000 m³, in particular for increasing the ph - value and the buffering effect of waters, characterized in that, in acidic body of water and / or in water with acidic inflows having a ph - value of & 5,5 and sulfate contents of 400 mg / l, calcined dolomite with a proportion of 50% of cao + mgo and a ratio of magnesium / calcium content of 0,25 to 2 in a grain size of 0 – 3 mm, cao + mgo – components can be present in hydrated form, in acidic sulfate-containing body of water is introduced and at a ph - value of & 4,3 to 8,2, exclusively or additionally, carbonate - and / or hydrogen carbonate - and / or carbon dioxide containing substances and / or compounds in sulfate-containing body of water are introduced until the ph - value and / or the buffer capacity in the form of the ks_{4,3 - Value} a predetermined limit value for the ph - value in the range of 5,5 – 8,2 and for the ks_{4,3 - Value} in the region of..
