| 中文摘要 |
| 根据ABI艺的流程及主要特征,系统地分析了该工艺的开放系统原理、反应动力学原理和生物相分田原理。根据开放系统原理考虑了城市污水输送管道系统中占A段曝气池微生物量15%-20%微生物的作用;根据反应动力学原理采用了2个反应器,从而使反应器所需总容积节省38%以上;根据不同微生物的生长特点及其对环境的要求,进行了生物相的分隔,从而使处理效果更为有效和稳定。实践表明,AB工艺可比传统活性污泥法节省工程投资15%-25%,节省占地10%-15%,节省运转费用15%-25%。 |
| 英文摘要 |
| Based on the flow-sheet and main characteristics of AB process,this paper analyzed the three basic principles systematically,i.e.open-tryout system principle, dynamic principle of biological reaction and biomass separation principle of the process. Based on the open-to-out system principle,AB process utilized fully the microbes which accounts for 15%-20% to the biomass in A-stage aeration bond; based on the reaction dynamics, AB process applied two reactors which are oprated in series resulting in the reduction of total reaction volume of more than 38%. According to the requirements to the environmental factors of different biomass,AB process separates the biomass under different condition leading to more effective and stable treatment.It was practically showed that the AB process is much lower in capital investment (15%-25%),land requirement(10%-15%)and in oprational cost (15%-25%). |
