Beschreibung
Zusammenfassung:The invention relates to biological purification of sewage containing high concentrations of ethylene glycol. The method comprises treating the sewage containing ethylene glycol and microelements with the sources of phosphorus, nitrogen and a microorganism of genus Arthrobacter. Then said microorganism is cultivated at 20-35 DEG C until the sewage is purified from ethylene glycol. Said method permits biological purification of the sewage containing over 2000 mg/dm of ethylene glycol to a purification rating of 99%. Diethanolamine is used as a cooxidant at concentrations of over 4000 mg/dm . Arthrobacter simplex 667, arthrobacter variablis 667, arthrobacter species 126 and arthrobacter species 127 are given as the strains capable of being used. Microelements are examplified by K, Mg, Zn, Fe, Mn, CaNO2 and SO4.
