| 摘要 |
The invention relates to a method for the treatment of industrial effluent gases for the removal of sulphur dioxide, according to which the gases are contacted with an absorbing solution, containing alkali metal sulphite and bisulphite, the solution, before the contact stage, being pre-treated with air or other gas inert to the solution, preferably a gas devoid of oxygen, whereby the SO2 partial pressure of the solution is reduced, thus enhancing the SO2 removal from said effluent gases.
