超临界水氧化处理橡胶废水的实验研究

Study on Supercritical Water Oxidation of Rubber Wastewater

橡胶废水具有水量大、有机污染成分含量高且难于生化降解等特点,是难处理的工业废水之一。超临界水氧化法是一种高浓度难降解有机废水处理技术,该技术可以在极短的反应时间内将废水中的有机物完全氧化分解,完全去除有机废物中的有毒有害物质,对COD、氨氮、硫的去除率都达到了80%以上,出水水质完全符合排放标准的要求,是一种解决橡胶污水处理难题的有效途径。

Rubber wastewater is generally characterized with large water volume and high organiccontaminants,and difficult to be biologically degraded compared to the ordinary wastewater. Application of SCWOtechnology to rubber wastewater treatment showed that the average removal rates of COD,NH3-N and sulfur wereall above 80%. The concentration of organic pollutants can be further degraded, and the quality of treated watermeets the requirement of《Integrated Wastewater Discharge Standard 》. This technology will possibly be anefficient means to overcome the difficult in the treating process of the rubber wastewater.
