厌氧生物转盘处理高浓度有机废水的研究

Study of Anaerobic Rotating Biological Contactor in the Treatment of Organic Wastewater of High Concentration.

厌氧生物转盘是一种处理高浓度有机废水和污泥的新技术,本研究结果表明,在中温条件下,COD容积负荷为5.44—11.6kg/m^3·d,COD去除率为70.6—74.7％,总磷去除率为35—48.5％,废水中有机氮基本上转化为HN_3-N.每去除1kgCOD产生沼气0.41—0.65m^3,约耗电0.5—0.8kw·h.该法构造简单、启动快、运行管理方便.

Anaerobic rotating biological contactor is a new device for the treatment of organic wastewater of high concentration and sludge. This study demostrated that under mesophilic conditions. COD volume load could be 5.44-11.6 Kg/m3 d and removal rates for COD and T-P could reach 70.0-74.7% and 35.0-48.5%, respectively. During the process, organic nitrogen in wastewater broke down to NH3-N. For the removal of every 1 Kg COD. 0.5-0.8 Kw h of energy would be consumed and 0.41-0.65M3 of marsh gas produced. The process is simple in construction, easy to start and convenient in operation.
