摘要
以典型的POPs——多氯联苯及二口恶英为代表,综述了水体中POPs的来源及其造成的水污染状况,指出传统的污水处理技术难以去除水中的POPs,重点介绍了国内外利用外场(声、光、电等)辅助氧化技术降解水中低浓度POPs的研究进展,并分析了各种外场技术的优缺点,指出单膜微波降解技术是一种极具发展前景的新型水处理技术。
The source of the representatives of POP （ polychlorinated biphenyls and dioxin） in water and the contaminative status are summarized. The fact that conventional sewage or waste water treating processes are difficult to degrade POP in water are indicated. The research progress on lower concentration POP degradation by external power assistant technology at home and abroad are introduced in detail, and the advantages and disadvantages of diversified external power technology are analyzed. At last, it is pointed out that mono -membrane microwave degradation technology is a more attractive strategy to dispose POP all over the world.
