Mine underground water iron and manganese removal process and system |
| abstract |
The invention provides a mine underground water ferro-manganese removal process, which comprises the following steps: performing primary pH adjustment treatment on the aerated and oxidized underground mine water to make the pH value be 6-9; performing chlorine oxidation treatment after precipitation and filtration treatment, and simultaneously performing aeration and secondary pH treatment to make the pH value be 6-9; and then manganese sand filtration treatment is carried out to obtain the mine underground water without iron and manganese. The invention also provides a mine underground water ferro-manganese removal system which comprises an aeration oxidation tank, a primary sedimentation tank, a primary filter tank, an oxychlorination tank and a manganese sand filter. The mine underground water ferro-manganese removal process and system provided by the invention are used for solving the problem that ferro-manganese ions in the existing sewage exceed the standard, so that the effluent quality stably reaches the national standard. |
