Prospects for Biological Treatment of Oleaginous Crop Processing Waste Water

Abstract

The possibility of microbial treatment of waste waters of an enterprise for deep prcessing of oilseeds has been studied. It was found that the most effective cleaning occurs when using a consortium that includes strains Rhodococcus ruber 1NG, Bacillus
 sp. FL X-5, Azotobacter sp. FL9-MV and Rhodococcus wratislaviensis G-13. The efficiency of purification of oily wastewater with an initial COD of 4425 mg O2/dm3 on the 5th day was 37.7 %, on the 21st day – 40 %. High results of purification of the investigated effluents were also achieved with the use of microbial preparations of the Antoil series. The cleaning efficiency on the 21st day was 33.7–37 %.
 The results obtained indicate that the use of specialized microorganisms-destructors at the stage of biological wastewater treatment of enterprises for deep processing of oilseeds is promising.
