TUBAF处理城市污水的有机物去除动力学研究

Kinetic Study on Organic Pollutants Removal of TUBAF for Treating Municipal Wastewater

本研究采用两段上向流曝气生物滤池(TUBAF)处理城市生活污水,以两段上向流曝气生物滤池的有机物去除动力学为研究对象。其中TUBAF C段采用半软性填料,根据进出TUBAF C段反应器流量和有机物浓度的变化,建立了本段有机物降解的模型,并求得了动力学参数;TUBAF N段采用酶促好氧填料,通过对TUBAFN不同的水力负荷q和滤池过滤层深度H有机物浓度的变化,对TUBAF N有机物的降解模式进行了建模,并确定了动力学参数,为进一步深化对曝气生物滤池处理机理的认识提供参考。

This paper is about the treatment of municipal wastewater using Two - Sect Upflow Biological Aerated Filter （TUBAF）, the kinetic equation of organic pollutants removal were studied. Semi - soft media were used in TUBAF C, based on organic pollutants and flow variety in the TUBAF C, the model of pollutants removal was established, while with Enzyme - enhanced aerobiosis bio -filling used in the sect of TUBAF C, based on the variety of organic pollutants in different Filter - bed depth, the model of pollutants removal was also established, and the solution were deduced.
