The possibility of biological treatment of sewage from the production of organic polymers was assessed. The chemical quality of raw and treated sewage (CODCr, BOD5, ammonia nitrogen, nitrate nitrogen, total suspension, pH, chlorides and sulfates) was analyzed. The level of reduction in the analysed sewage quality indicators (%), sewage biodegradability (α) and the technical efficiency of treatment (Psw) were determined. It was shown that the limited effectiveness of the treatment process results from the excessively high load of organic contaminants. The analysed sewage contains substances which do not biodegrade easily, negatively influencing the conditions for activated sludge processes in the bioreactor. The activated sludge is characterized by low biodiversity and has an insufficient structure. The treatment process requires an introduction of technological changes which will lead to a decrease in the load of sewage entering the bioreactor. (original abstract)
