【摘要】 为研究混合液温度对IMBR污泥增殖动力学特征的影响规律,进行了动态试验,考察了10℃、15℃、20℃、25℃、30℃、35℃6个温度条件下的动力学特征。研究结果表明:本实验条件下,温度对理论产率系数与衰减系数都有显著影响,理论产率系数随温度的升高而降低,理论产率系数与温度符合乘幂关系;得到的衰减系数要高于普通的活性污泥法,衰减系数与温度仍符合关系式Kt=K20(tθ)(t-20),求得的温度系数在传统活性污泥法的取值范围之内。更多还原

【Abstract】 For the aim of finding out how the temperature of mixed liquid affects the sludge multiplication dynamic characteristics of IMBR,a dynamic experiment was adopted to investigate the dynamic characteristics at the temperatures of 10℃,15℃,20℃,25℃,30℃,and 35℃ respectively.The result showed that the temperature has sufficient effect on theoretical product rate factor and subtractive factor.The theoretical product rate factor declines when the temperature rises,and the relation between them accords with the power in this experiment.The subtractive factors of all temperatures in this experiment are higher than those by traditional active sludge techniques,and the relationship between subtractive factor and temperature can be described with the following formula: Kt= K20(θt)(t-20),with the temperature t factor in the range of tradition active sludge techniques.更多还原
