Method and apparatus for synchronously removing heavy metal and nitrate in drinking water |
| abstract |
A method for synchronously removing heavy metal and nitrate in drinking water is provided. Micro molecular organic carbon including formic acid as the major component and acetic acid or ethanol as the minor component is added into raw water to be treated for acidizing so as to adjust pH to 5-3.9. The acidized water is passed through a heavy metal removing column (5) in the presence of oxygen, and heavy metal is removed by using fillings therein. The water, in which heavy metal is removed, enters into a denitrification reaction column (6) for removing nitrate in the water via synergistic effect of heterotrophic and autotrophic denitrification, wherein the micro molecular organic carbon without excessive additive amount is used as a carbon source and fillings in the denitrification reaction column (6) are used as an electron donor source. The residues in the water are filtered by aerobic circulation to obtain drinking water, from which heavy metal and nitrate are removed. An apparatus for carrying out the above method is also provided. In the method, heavy metal and nitrate in the raw water can be efficiently removed and the effluent is alkalescent. |
