Key words: oxidation in supercritical water, waste water treatment, cellulose production, coagulation, flocculation
The method of oxidative waste water (WW) treatment in the supercritical conditions (SC) is considered. It is demonstrated that the values of water parameters required for the downstream biological purification are accessible if coagulation-flocculation treatment of WW on the first stage is combined with oxidation in the SC on the second stage. The necessity of such combination is caused by low degree of lignin degradation in the conditions of oxidative treatment (400 °C, 24 MPa, Н2О2 as oxidant).
