废水中残留泰乐菌素的降解

Degradation of Residual Tylosin in Waste Water

以泰乐菌素生产车间产生的废水为试验对象,考察酸、碱和氧化剂对废水中残留的泰乐菌素的降解效果。结果表明,在废水加入2.5%氢氧化钠(60℃)或0.5%次氯酸钠(25℃),可降解泰乐菌素,残留量达到限度要求,可通过活性污泥池进行统一生化处理后排放;而酸处理效果较差。考虑处理成本及健康、环境、安全要求,实际生产中可用碱处理的方法。

The degradation effects of the residual tylosin in waste water by acid, alkali and oxidant were investigated. It was concluded that the degradation of tylosin was obvious with adding 2.5% sodium hydroxide at 60 ℃or 0.5% sodium hypochlorite at 25 ℃ into waste water, and the residual content of tylosin in the waste water could meet the requirements of limitation, which could be discharged after treating by activated sludge. However, the effect of acid treatment was poor. With the consideration of production cost and EHS requirements, the alkali treatment method could be used in the practical production.
