POSSIBLE IMPACTS OF CHEMICAL INDUSTRY WASTEWATER TREATMENT PLANT EFFLUENT WATER MIXED WITH ORGANIZED INDUSTRIAL ZONE EQUALIZATION TANK WASTEWATER
 
In this study, the characterization and biological treatability of a chemical industry producing organic peroxide, initiator, accelerator and dye dryers and its biological treatability and dilution factor when mixed with OSB(organized industrial Zone) waters were investigated. After sampling, the samples were delivered to the laboratory and stored in a refrigerator at 4oC according to standard methods and laboratory analyzes were performed as soon as possible. The biological treatability tests were carried out using a batch reactor. Catalysts and composite materials produced in the plant were used in many sectors such as paint, plastic, chemical and petrochemical, rubber. The production of the enterprise includes chemicals, initiators, accelerators and catalysts used in polyester and paint industries. The COD pollution concentrations of the mixture produced in the chemical plant effluent and O.S.B influent wastewater were 1634, 1397, 1345 and 1420 mg / l, respectively. The sulfate concentrations of both plant wastewater mixtures were 634, 468, 432 and 484 mg / l, respectively. This wastewater was not toxic to microorganisms. In the biological treatment process in a pilot scale semi-batch reactor with a volume of 5 m3, the COD value decreased from 10030 mg/l to 6400 mg/l at the end of the 8th day. Key words: Chemical industry, Organized industrial zone, COD, Biological treatment
