摘要
研究了分别填充堆肥和污泥的生物滤塔对含三甲胺气体的处理能力。结果表明,两种生物滤塔均能有效处理含三甲胺的气体,对三甲胺的去除率几乎达到了100%,三甲胺被生物降解并生成氨。堆肥生物滤塔各段填料中的硝态氮含量随时间的延长呈显著提高的趋势,但pH值出现下降,说明其中发生了氨的硝化作用。而在污泥生物滤塔中,随着氨的积累则各填料层的pH值迅速升高,并且没有观察到亚硝态氮以及硝态氮含量的增加,因此其不具备进一步降解氨的能力。
The effectiveness of the compost biofiher and sludge biofiher in trimethylamine （TMA） removal was compared. The results show that TMA is effectively removed by both biofilters, and its removal efficiency nearly reaches 100%. TMA is degraded to ammonia in both biofihers. In the compost biofiher, the nitrate nitrogen is increased with time nitrification. However, in the sludge biofilter, pH prolongation, and pH is decreased, showing ammonia is increased with ammonia accumulation, and the nitrite nitrogen and nitrate nitrogen are not increased, showing that this biofilter has not ammonia degradation capacity.
