摘要
生物接触氧化法是一种广泛应用于废水处理的方法,填料是生物接触氧化法的核心部分,选择合适的填料能够加速生物接触氧化法的处理效率,并能使其运行稳定。选取了4种不同的填料,分别从COD、NH3-N、浊度的去除以及生物膜量等方面对各种填料进行了比较研究。结果表明,悬浮填料挂膜快,出水水质良好且稳定,微生物生长特性最优,是一种理想的接触氧化法填料。
Biological contact oxidation is a method which is widely used in wastewater treatment and packing material is very important in this process. Adopting suitable packing material can bring high efficiency and steady operation to the reactor. Four different packing materials were chosen in the experiment to demonstrate their efficiency in the removal of COD, NH3-N, turbidity during wastewater treatment. The result shows that the suspended packing material is better than the others due to its faster forming of the biofilm and optimum characters in microorganism growth and better wastewater treatment efficiency. It is an ideal biological contact oxidation packing material.
