This paper analyzed parameters of biological pre-treatment process of petrochemical wastewater collected after styrene and propylene oxide production. The values of organic pollution load are determined and the cleaning efficiency is calculated. The composition of the microbial community that participated in the pre-treatment process in the bioreactor is studied.
