A method for cleaning / treatment of acidic, iron - and sulfate-containing waters

摘要

A method for cleaning and / or treatment of acidic, iron - and sulfate-containing waters, wherein– in a first treatment chamber a oxidation of fe (ii) to fe (iii) by iron-oxidizing microorganisms at a ph - value is ≦ 2,8,– in a second treatment chamber of the ph - value to 3,2 to 3,5 is lifted, whereby from the fe - iii - ions and the sulfate ions iron hydroxycaproic sulfates are produced, and, and– a rate of oxidation in the first treatment chamber by recycling of microorganism-containing iron sulfates hydroxycaproic from the second treatment chamber and / or by supply of co.sub.2₂ in the first treatment chamber is controlled.
