  • 摘要: 采用自制的有机膨润土对苯胺基乙腈生产废水进行吸附预处理实验，分别考察了废水pH、有机膨润土投加量、吸附温度及吸附时间等因素对吸附率的影响。结果表明，有机膨润土对苯胺基乙腈生产废水进行吸附预处理是可行的，其较优的工艺条件为：有机膨润土投加量为20 g/L、废水pH为6.0、吸附温度为30℃、吸附时间为60 min，在此条件下COD及苯胺去除率分别达到了23.3%及54.4%，可生化性BOD5/COD由难以测量出可提高到0.11左右。
    Abstract: A preprocessing absorption treatment of N-phenylglycinonitrile wastewater with self-made organo-bentonite was conducted to find out the impact on absorption rate by such factors as pH， organo-bentonite addition， adsorption time and temperature. The test results indicated that it was feasible to do the preprocessing absorption treatment of N-phenylglycinonitrile wastewater with organo-bentonite， and the advantageous process conditions were as follows， the organo-bentonite concentration of 20 g/L， the pH of wastewater of 6.0， the adsorption temperature of 30℃ and the adsorption time of 60 min.Under these conditions， the organo-bentonite had a high ability of adsorption， the removal rate of COD and anilines could reach 23.3% and 54.4%， respectively and the BOD5/COD could be raised to 0.11， which was otherwise unable to be tested.
