METHOD OF SEWAGE WATER PURIFICATION FROM PHENOL COMPOUNDS Russian patent published in 2013 - IPC C02F3/34 C12R1/40 

FIELD: chemistry.

SUBSTANCE: invention relates to field of biochemistry. Sewage water with increased content of phenol compounds 300 - 1200 mg/l, content of sulfide-ions to 64.1 mg/l and content of sulfate-ions to 401.4 mg/l and 1843.7 mg/l in case of sparging with air, is passed through column type reactor. Reactor contains adsorbent - petroleum coke, onto which cells of strain of aerobic bacteria Pseudomonas putida 131 All-Russian collection of industrial microorganisms B-10894 are immobilised. Orthophosphoric acid or its salts are preliminarily dissolved in sewage water as biogenic additive in order to obtain pH 7-8, optimal for phenol destruction by bacteria strain.

EFFECT: invention ensures increased quality of purification of sewage water, which contain sulfide-ions and sulfate-ions, from phenol compounds to 0-50 mg/l.
