兰炭废水预处理技术研究进展
|
摘要
综述了两种兰炭废水预处理技术:酚回收和高级氧化预处理。采用以萃取和吸附为主的酚回收预处理技术,可以高效回收废水中的酚类,但存在萃取剂损失率大、吸附材料再生困难等问题;采用高级氧化预处理技术,能保证良好的处理效果,但对于大量的兰炭废水,运行成本高。针对现有兰炭废水预处理工艺的特征和存在的问题,展望了高浓度废水处理技术的发展方向。
2 semi-co king wastewater pretreatment technologies including phenol recovery and advanced oxidation pretreatment were reviewed. The phenol extraction and adsorption recovery pretreatment could efficiently recover the phenol in the wastewater, but the loss rate of the extractant was large and the adsorption material was difficult to regenerate. The advanced oxidation pretreatment technology had good treatment effect, but the operating cost was high for the large amount of semi-coking wastewater. In view of the characteristics and problems existing in the treatment process, the outlook of high concentration wastewater treatment technology was described.
