Abstract
In this study; variation of effluent BOD5’s (Se) with reaction time (tr) in Sequencing Batch Reactor (SBR) unit for textile industry wastewater treatment plant and effective parameters on this variation have been researched. Determination of appropriate reaction time (tr) is an important value for design and operation of activated sludge unit. An appropriate kinetic equation for Sequencing Batch Reactor (SBR) unit has been researched and simulation studies were made according to parameters’ minimum, average and maximum values. In simulation studies, it has been observed that effect of parameters (So, Q, k, Vb, Va, Vab) on Sequencing Batch Reactor (SBR) effluent concentration (Se) variation with reaction time (tr). In addition, theoretical variation of effect parameters on effluent BOD5’s (Se) and interaction of these parameters were researched. Ten different values with determined ranges were chosen for each parameter. Calculations have been done using our computer program. In the result of calculations were obtained theoretical values. Calculated values have been plotted and fitted graphics by Grapher program. Also, regression coefficient were determined and given suitable equations. This method of Sequencing Batch Reactor offers a significant improvement for the treatment of textile wastewater and this theory can be used to help define Sequencing Batch Reactor (SBR) kinetics with the optimum operational characteristics.
