摘要
以工程上最常用的人工湿地污水处理反应器SSFW为例,讨论了人工湿地污水处理机理,提出了在湿地床内存在着A2/O状态,并以推流式纵向扩散生化反应器(PFDBR)为模型,建立了SSFW床污水处理的数学模型,得到了SSFW有机物降解规律及其生化反应动力学常数的具体表达式.
Constructed wetland sewage disposal reactors can be classified into SFW, SSFW and VFW.Taking the commonly-used SSFW as an example,the mechanism of CW sewage disposal is discussed,the fact is given that there exists state A^2/O,the digital model of bed SSFW sewage disposal is set up, modeled by PFDBR (Pushing Flow Diffuse Bio-Reactor), and the law of organic matters dissolving and the specific expressions of the constants in Bio-React Kinetics are concluded.
