METHOD FOR NEUTRALISATION OF SULPHIDE-ALKALI SEWAGE Russian patent published in 2016 - IPC C02F1/72 C10G53/14 C10G27/12

Abstract RU 2587437 C2

FIELD: chemistry.

SUBSTANCE: method for neutralisation of sulphide-alkali sewage includes catalytic oxidation of sulphides with hydrogen peroxide. Sulphide-alkaline sewage is mixed with water and cooled. Oxidation process is realised in two stages: oxidation of sulphides at temperature 10-90°C and after-oxidation of residual sulphides with introduction of hydrogen peroxide for both stages.

EFFECT: invention makes it possible to increase productivity and safety of technological process.
