Abstract

Purification method of waste water by oxidation in supercritical aqueous media (OSAM) has been considered. It is shown that the achievement of acceptable parameters of waste water for biological treatment plants is possible upon combining of a coagulative-flocculative process with OSAM. The need for such a combination is determined by the insufficient degree of degradation of lignin using only OSAM, conducted at 400°C and 24 MPa (oxidizer–H2O2).
