脲基乙酸内酰胺的废水处理研究

Study on the treatment of wastewater from the production of glycolylurea

采用浓缩-氧化-碱洗-活性炭纤维吸附工艺处理生产脲基乙酸内酰胺的废水,着重研究了活性炭纤维吸附规律及再生方法。研究表明:该工艺处理后的废水COD去除率为95.0%,乙醇氰去除率为97.6%,脲基乙酸内酰胺去除率达92.0%,废水的气味和颜色全部除去,废水达到排放标准。

Glycolylurea wastewater is treated by flocculation - concentration - oxidation - alkali treating - activated carbon fiber(ACF) adsorption. The adsorption rule and the repeated method of activated carbon fiber have been studied emphatically. The overall removal rate of COD is 95.0%, that of glycolonitrile 97.6% and that of the production glycolylurea 92.0%. The smell and color of wastewater are removed completely. The requirement of the discharge standard of the effluent has been reached.
