【摘要】 当前,生物膜法是一种好氧型生物污水处理工艺,广泛应用在工业废水和城市污水处理中。生物膜法由生物滤池工艺、生物转盘工艺、生物接触氧化法工艺和生物流化床法工艺等组成,本文对其进行了深入研究。与活性污泥法比较,生物膜法具有独特的优势,如运行管理方便、加快城市发展、运行稳定良好等,对氮、磷及一些重金属具有良好的去除效果。更多还原

【Abstract】 At present, biofilm process is an aerobic biological wastewater treatment process, which is widely used in industrial wastewater and municipal wastewater treatment. The biofilm process is composed of biofilter process, bio-rotating disc process, bio-contact oxidation process and bio-logistics chemical bed process, etc. In this paper, the biofilm process is studied in depth. Compared with activated sludge process, biofilm process has unique advantages, such as convenient operation and management, accelerating urban development, stable operation, etc. It has good removal effect on nitrogen,phosphorus and some heavy metals.更多还原
