| 摘 要： | 针对氨基废水的成份和特性，进行了废水静置分离、萃取、加尿素除甲醛、蒸馏脱醇等预处理试验。目的是回收废水中的可利用成份，同时降低废水中的CODcr浓度。根据试验结果，提出了在碱性条件下直接蒸馏脱醇是可行的。既可回收醇5％～7％左右，又能去除CODcr达80％以上。

| Abstract: | In order to recover the useful matter from amido waste water,based on the feature of amido waste water,We do some pre-treatment experiment of waste water such as separation,extraction,removing formaldehyde by adding urea,distilling de-alcoholing.On the basis of the result of the experiment,we advance it is able to distil out alcohol directly on alkalinity,which not only can recover alcohol to5%-7%,but also remove CODcr up to80%. |
