Özet
Eight polycyclic aromatic hydrocarbon (PAH) compounds which have been accepted as priority micropollutants by European Union (EU) were analyzed both in wastewater and sludge lines throughout three full scale (located in city, sub-province and village) WWTPs during 12-month sampling period. Investigated WWTPs have different treatment types including advanced biological treatment, stabilization pond (SP) and constructed wetland (CW). Removal efficiencies for total PAH compounds varied from 48% in CW to 85% in advanced biological treatment plant. The maximum concentrations of 360–2282 ng/L observed for naphthalene in raw wastewater were decreased to 103–370 ng/L by treatment processes. Minimum concentration were detected for benzo(k)fluoranthene (B[k]F) and benzo(g,h,i)perylene (B[g,h,i]P) ranged between 8 and 12 ng/L and 19–33 ng/L, respectively. While minimum removal efficiencies were obtained for B[k]F and B[g,h,i]P maximum removal efficiencies were obtained for naphthalene in all WWTPs. PAHs present in minimum and maximum levels in the sludge samples were detected as 54 and 6826 ng/g for the B[g,h,I]P and naphthalene, respectively. Considering the removal mechanisms, PAHs have been determined to be removed by biodegradation or vaporization up to 84% and by settling (adsorption onto sludge) up to 2%. The greatest portion (99%) of naphthalene and anthracene were determined to be biodegraded or vaporized in biological treatment due to their low molecular weights. On the other hand, mechanism of adsorption onto sludge was determined as negligible for these two compounds. In addition, approximately 14% of PAHs were discharged to the receiving environment. Among the different WWTP types investigated, advanced biological treatment was found to be the most efficient plant for the removal of PAH compounds.
