文章根据传统生物转盘的原理对其进行改进,将轻质多孔聚氨酯泡沫载体固定于中间用来代替盘片,形成新型的生物转盘装置-固定化载体生物转盘,即I Carrier-RBC,研究了其影响因素以及对低浓度有机污水中CODCr的降解特性。研究结果表明：I Carrier-RBC系统在最佳运行工况,即R=1 r/min,HRT=2 h时,对低浓度有机污水中的CODCr和NH3-N均具有良好的去处效果,当进水CODCr和NH3-N的浓度分别为48~330 mg/L、13.87~71.77 mg/L时,系统对CODCr和NH3-N的去除率分别为59.03%~87.13%、80.17%~93.12%;同时初步确定此系统对有机物的降解遵循一级反应动力学规律,反应速率常数K=0.925。

The paper based on the principle of the traditional rotating bio-disc to improve it,fixed the light and porous urethane foam carrier into it to used instead of plate of rotating bio-disc,forming new immobilized rotating bio-disc device,namely I Carrier-RBC,and studied its influence factors and degradation characteristics of CODCr and NH3-N in low concentration organic wastewater.Research results showed that： the system of I Carrier-RBC＇s under best operation condition that was R = 1 r/min,HRT = 2 h,it had good removal effect for CODCr and NH3-N in low concentration organic sewage,when the influent CODCr and NH3-N concentration was 48~330 mg/L and 13.87~71.77 mg/L respectively,the removal rate of system for CODCr and NH3-N was 59.03 %~87.13 % and 80.17 %~93.12 % respectively.Meanwhile,initially defined the system degradation reaction of organic followed the first order reaction kinetics,reaction rate constant K=0.925.
