Abstract

Background and Objectives: Collection and treatment of wastewater due to adverse effect of improper wastewater disposal to the environment is inevitable and necessary. So that establishing of wastewater treatment plant toward regular evaluation of treatment systems performance is necessary for achieving environmental standards. Biokinetic coefficients obtained from laboratory studies are vital factors in industrial applications. The aim of present study was PERFORMANCE EVALUATION and BIO-KINETIC COEFFICIENTS determination of ACTIVATED SLUDGE unit in Sanandaj wastewater treatment plant.Materials and Methods: This cross-sectional study implemented in wastewater treatment plant of Sanandaj using continuous ACTIVATED SLUDGE process. In this study 30 samples were taken from influent and effluent wastewater and experiments carried out on them. The wastewater quality parameters including BOD5, COD, TSS and MLSS were measured; removal efficiency and BIO-KINETIC COEFFICIENTS such as yield coefficient maximum substrate utilization rate (k), endogenous decay coefficient (kd), half saturation coefficient (Ks), Yield coefficient (Y) and specific maximum growth (m_max) were also calculated.Results: Mean of COD, BOD5 and TSS removal was obtained 90.3 ± 3.3, 93.9 ± 1.9 and 86.4 ± 4.2, respectively.According to MLSS/MLVSS concentration, K, Ks, Y, Kd andm_max were calculated 2.5 d-1, 7.25 mg/L, 0.013, 0.027 d-1 and 0.03 d-1, respectively.Conclusion: Effluent derived from the ACTIVATED SLUDGE treatment plant in terms of achieving to BOD5, COD and TSS standards for discharge into surface water or agricultural purposes is desirable. Results of this study resulted in calculation of bio-kinetics confections. The BIO-KINETIC COEFFICIENTS obtained in this study can be used in designing of similar plants, especially in cold areas.
