Abstract:
The progress in biochemical treatment technology of acrylic fiber wastewater according to the time sequence is reviewed.Two main periods are divided, one aims at the removal of main organic compounds by cultured microorganisms and the other aims at the removal of NH3-N.But so far all the biochemical methods are traditional and dif ficult to control.

摘要:
对腈纶废水生化为主的处理工艺流程随时间推移的演变作了一个回顾、总结,对不同腈纶厂的处理工艺特点及其运行过程中出现的问题作了对比、归纳。纵观腈纶废水以生化为主导的处理技术的发展历程,无不随着环保工作者认识的深入、新的处理理论的提出以及新的环境问题的暴露而改变处理目标和针对对象。但迄今为止的方法都属于传统处理方法,不同物质和菌种之间的相互干扰问题没有得到根本解决。
