    摘要: The present invention relates to a method and as apparatus for simultaneous removal of thiosalts and nitrogen compounds in waste water, wherein the amount of thiosalts in the waste water is larger than the stoichiometric demand for the autotrophic nitrogen removal. The apparatus comprises a bioreactor (1) including an autotrophic bacteria culture carrying out a denitrification process using the thiosalts as electron donors, having an inlet (3) for receiving the waste water, and an outlet (4) for discharging the purified water. The apparatus comprises an oxygen supply device (6) arranged to supply oxygen to the water in the reactor and a control unit (10) arranged to control the content of dissolved oxygen in the reactor such that the excess of thiosalts is oxidized by the oxygen at the same time as the denitrification process is maintained.
