摘要:

将简化的ASM1与生物膜动力学方程结合,运用均相生物膜概念,建立好氧生物膜的模型,并且针对焦化废水的特征,进行模型修正。对酒钢集团公司焦化厂A/O生物滤池处理中O段曝气生物滤池COD和氨氮组分的降解过程进行了模拟,并且研究了酚浓度变化、生物膜脱落速率、温度和溶解氧浓度变化对出水COD、氨氮和硝态氮的影响。

Abstract:

An inhibited aerobic bio-film model has been established through combining the simplified activated sludge model No.1 (ASM1)and the equations bio-film dynamics, and using the concept of homogenous bio-film. The model is modified, according to the characteristic of coking wastewater. The degradation process of COD and ammonia-nitrogen component of A/O biological filter system are simulated at Coking Plant, Jiugang Co., Ltd. The effects of the changes of phenol concentration, the bio-film abscission speed, temperature, and dissolved oxygen changes on the effluent COD, NH4+-N, NOx--N have all been studied.

Key words: biofilm, activated sludge model No.1, coking wastewater, inhibition constant
