| 摘 要： | 从理论计算和试验两方面探讨了生物除铁除锰滤池中的曝气溶氧问题。结果表明，生物滤层除铁除锰不需要高溶解氧，也不需要通过散除CO2来提高原水的pH值，相反CO2可作为微生物繁殖代谢的碳源。认为简单的曝气充氧方式与生物滤池的结合可大大简化传统的处理流程。

| Abstract: | Oxygen demand for iron and manganese removal in biofilter was discussed by means of theoretical calculation and experiment.The results show that neither high level of DO nor CO 2 dissipation in raw water is required for iron and manganese removal in biofilter bed,but rather CO 2 can be used as carbon source for microbial metabolism.It is considered that the simple aeration in combination with biofilter may result in significant simplification of the conventional treatment process. |
