摘要
阐述了PTA精制废水处理工艺即萃取-超滤-反渗透系统的原理以及该系统的运行情况及出现的问题;分析了反渗透膜受损机理,并通过实验提出了解决方案;通过吸附操作来处理废水中少量的PX,以达到保护膜的作用,从而优化了废水处理工艺;通过实验论证了方案的可行性。
Elaborate the principle of the PTA refining wastewater~ recycling system,operational condition and existing problem of the system ; to analyze the principle of impaired reveise osmosis membrane, through expriments put forward solution ; through adsorption operiation handle a little PX of waste water, in order to achieve effect of pro- tection the membrane.
