减少制革污水中氨氮含量的工艺研究

Study on Reducing Ammonia-nitrogen in Tannery Effluent

本文讨论了制革生产中氨氮的产生及在各工序的分布， 并通过清洁工艺有效地降低了制革污水中的氨氮含量， 减少制革污水的污染问题。

Ammonia-nitrogen production and distribution in various process will be discussed in this topic. In order to decrease the pollution problem in leather industry, cleaning technology for reducing ammonia-nitrogen content in effluent will be found out in this paper.
