摘要
采用不同方法对湿法腈纶废水进行预处理 ,比较了它们的处理效果和特点。研究中使用的菌种预处理方法达到了理想的效果 ,废水中大分子有机污染物被迅速、高效地分解为挥发性脂肪酸和氨氮等 ,为后续的接触氧化以及反硝化创造了良好的条件 ,COD和TKN的总去除率分别为 92 %和 85 % ,最终出水达到或优于行业二级排放标准。
Treating acrylonitrile containing wastewater by using three kinds of processes has been carried out. It is found that the application of special microbes to the No.3 treatment process as wastewater pre treatment measure could result in the highest removal of COD and TKN.Special microbes effectively degrade most of the polymers such as acrylonitrile, phenol and so on to produce volatile fat acids which could be easily degraded and could greatly enhance bio denitrification.The total COD and TKN removal rates of No.3 treatment process are 92% and 85%, respectively.
