Abstract

In this study, it was aimed to make an efficient wastewater treatment by using adapted bacteria cultures to support and strengthen the biomass in aeration basin of the wastewater treatment plant, when the treatment processes are not sufficient in biological wastewater plants (BWWTP) for industrial wastewater which contains toxic and recalcitrant organic chemicals. For this purpose, petrochemical industry was chosen for field of study. The physical, chemical (flow rate, dissolved oxygen, temperature, chemical oxygen demand, total suspended solids, phenol, NH4-N, phosphorus, pH) and microbiological analysis (indicator microorganisms) were carried out predominantly to observe the performance of the treatment plants. Microbiologic data (during the applications) and chemical data which were recorded before and during the applications in the biological wastewater treatment plant of petrochemical industry, showed that adapted bacteria cultures could stabilize discharge limits from independent influent parameters. The results indicate that the adapted bacteria cultures easily induce healthy biomass during the biological treatment processes in the tested system. It can be suggested that this method may be applicable to develop healthy biomass in these types of wastewaters.
