摘　　要：探讨了制革废水的生物接触法处理工艺。结果表明,好氧—缺氧—生物接触组合工艺是有效的方法。在最佳条件下,其COD_(cr)、BOD_5、氨氮和色度的去除率,可分别高达98％、98％、100％和98％。Techniques for treating ammonia nitrogen in tannery wastewater by biological contact process have been studied. The results showed that the integrated technique of biological contact oxidation-biological contact anaerobic treatment-biological contact aerobic treatment was an effective process for removing ammonia nitrogen in this wastewater. The optimal conditions of this technique have been found. By controlling the optimal technical condition strictly, removing rate of COD_(cr), BOD_5, ammonia nitrogen and colority were up to 98%, 98%, 100% and 98% respectively.
