Abstract:

Supercri tical water oxidation of paper making wastewater is investig ated in a batch pressure reacto rat 250~440℃ and 20~24 M Pa. The removal rate of TOC of the wastew ater could be more than 99%. The effects of temperature and oxidant concentration on the removal rate of TOC of the wastew ater have been studied.

Key words: supercritical water, oxidation, paper making wastew ater

摘要:

利用超临界水反应系统,在250~440℃和20~24MPa的条件下,研究了造纸废水在超临界水中的氧化分解反应。考察了反应温度、氧化剂浓度对造纸废水的降解反应的影响。经处理造纸废水的TOC去除率可达99%。
