用固相萃取-气相/质谱方法检测分了某典型污水处理厂各水处理单元内分泌干扰物质（EDCs）的存在情况。在污水、污泥中共计检出30种内分泌干扰嫌疑物质。结果表明，各种EDCs在水处理过程中的去除率为70%～99%，其中污泥吸附对EDCs的去除起重要作用。污泥中酚类物质浓度为17～35mg/kg，酞酸酯类物质浓度为25～77mg/kg，多环芳烃类物质为1.33～1.74mg/kg。同国外报道的结果相比，该污水处理厂水处理流程中酚类、酞酸酯类以及多环芳烃类的含量均处于较低的水平。

自氧氧化技术是高级氧化技术的一种。在水处理中己有百年的历史。近年来岂于对微污染物和难降解有机废水的关注，臭氧处理技术有了新的发展。本文总结了自氧的应用和三种臭氧氧化技术，指出了臭氧技术发展的方向。

研究了过氧化氢强化的真空紫外光催化(VUV/TiO2/H2O2)方法对水中微量硝基苯(NB)的去除效果,同时考察了H2O2投加量、NB初始浓度、重碳酸盐和腐殖酸对NB降解的影响.采用负载在钛片上的二氧化钛(TiO2)薄膜为光催化剂, 以能发射185nm真空紫外线(VUV)的紫外灯为光源.结果表明,去离子水中50 μg/L的NB反应60 s后去除率即达到97.9%.随H2O2投加量的增加,VUV/TiO2/H2O2对NB的降解速率先增后减; 初始浓度低于170 μg/L时,初始浓度对NB降解影响不大;重碳酸盐和腐殖酸对硝基苯降解有显著的抑制作用. VUV/TiO2/H2O2能快速有效地去除地表水(含碳酸盐和天然有机物)中的微量NB,5 min内初始浓度为90 μg/L的NB去除率达到94.1%, UV254在4 min内也降低53.3%.

生物过滤法是一种较新的空气污染控制方法，它利用微生物降解或/转化空气中的挥发性有机物以及硫化氢、氨等恶臭物质。本文主要介绍生物过滤法处理废气的基本原理，讨论填料种类、湿度、pH、温度等影响生物过滤法性能参数。同时综述了生物过滤法的应用范围以及对生物过滤法的改进。

The photodegradation of persistent and bioaccumulative perfluorooctanoic acid( PFOA)in water by185 nm vacuum ultraviolet (VUV) light was examined to develop an effective technology to deal with PFOA pollution. PFOA degraded very slowly under irradiation of 254 nm UV light. However, 61.7% of initial PFOA was degraded by185nm VUV light within 2h, and defluorination ratio reached17.1%. Pseudo first-order-kinetics well simulated its degradation and defluorination. Besides, fluoride ion formed in water, 4 shorter-chain perfluorinated carboxylic acids (PFCAs), that is, perfluoroheptanoic acid, perfluoorhexanoic acid, perfluoropentanoic acid, and perfluoorbutanoic acid. These were identified as intermediates by LC-MS measurement. These PFCAs consecutively formed and further degraded with irradiation time. According to the mass balance calculation, no other by products were formed. It was proposed that PFCAs initially are decarboxylated by185 nm light, and the radical thus formed reacts with water to form shorter-chain PFCA with one less CF2unit.
