| 摘 要： | 建立以污水驱动水轮机,再带动转盘和低坝的落水曝气充氧,和大气复氧,菌藻吐氧,达到多次充氧的多级生物系统工程,以逐级沉淀和多次降解,以及沙滤等设施代替工厂处理的复杂工程。在沈阳西部中试结果证明该工程结构简单、管理方便、处理效果高、节能节资.同时,建立了快速监测生物活性和水质毒性的方法.

| Abstract: | A multistage bio-system with new type BRD driven by wastewater and multistage stabilizing bio-membrane was set up for wastewater treatment. The drainage ditch used as treatment basin was stuffed with nylon ropes and was divided into a number of stages with dams built by oval stones in wire net. The BRD was driven by flow of wastewater and the aeration was accelerated by falling water from each BRD and dam. A grit filter was also used in the system. |

| Keywords: | multistage bio-system BRD wastewater. |
