This study encompasses investigation of treatment of pistachio processing industry wastewaters in a batch reactor under aerobic conditions, calculation of kinetic parameters and comparison of different inhibition models. The mixed microorganism culture used in the study was adapted to pistachio processing industry wastewaters for nearly one month and then concentrations from 50 to 1000 mg L of pistachio processing industry wastewaters were added to the medium and treatment was investigated in batch experiments. The Andrews, Han-Levenspiel, Luong and Aiba biokinetic equations were chosen for the correlations between the concentration of pistachio processing industry wastewaters and specific growth rates, and the kinetic parameters in these biokinetic equations were calculated. The maximum specific growh rate, semi-saturated constant and inhibition constant parameters, included in the Aiba biokinetic equation providing best fit among the other equations, had values calculated as 0.25 h, 19 mg L, and 516 mg L, respectively. The substrate value reaches maximum value and the specific growth rate at this concentration were calculated as 101.379 mg L and 0.1827 h, respectively.
本研究采用分批式反应器，在需氧条件下对开心果加工工业废水进行处理，计算动力学参数并比较不同的抑制模型。研究中使用的混合微生物培养物经过近一个月的时间适应了开心果加工工业废水，然后向培养基中添加浓度为 50 至 1000 mg/L 的开心果加工工业废水，并进行分批实验处理。Andrews、Han-Levenspiel、Luong 和 Aiba 生物动力学方程被选择用于关联开心果加工工业废水中的浓度与特定生长率，并且从这些生物动力学方程中计算出动力学参数。在其他方程中，Aiba 生物动力学方程提供了最佳拟合，其包含的最大比生长速率、半饱和常数和抑制常数参数值分别为 0.25 h、19 mg/L 和 516 mg/L。底物值达到最大值，在该浓度下的特定生长率计算值分别为 101.379 mg/L 和 0.1827 h。
