In the transition to unleaded gasoline, that one problem must be considered is to avoid introducing other even more hazardous pollutants to health or to environment. Based on investigating great number of literatures from domestic and abroad, to review the positive and negative effects of full composition such as benzene, aromatics, alkene and MTBE, and the vapor pressure on the motor vehicle emissions, and put forward the suggestions of laying down the environmental protection standard of gasoline and of fitting with the catalytic convertors.

在实施汽油无铅化的过程中,一个值得引起重视的问题是,要防止“污染替代”发生,即在消除铅污染的同时,防止另一些对环境和健康构成严重威胁的污染物被引入。该文在调研大量中外文献的基础上,综述了目前研究较多的苯、芳烃、烯烃、甲基叔丁基醚(MTBE)等汽油组成和汽油蒸气压对汽车排放正、负方面的影响,提出了制定汽油燃料环保标准、汽油无铅化和安装催化转化器同步进行等建议。

Volatile organic compounds (VOCs) in wastewaters from different stages in Datansha wastewa-ter treatment plant of Guangzhou were analysed, Monocyclic aromatics and chlorinated hydrocarbons (CHCs) were found to be the principal hazardous pollutants in influent. By the comparison of VOCs in the influent and effluent, it revealed that the removal efficiencies for benzene, toluene, ethylbenzene and xylene (BTEX) were almost 100%, and for several typical CHCs, 79%-89 % .

Volatile organic compounds (VOCs) in wastewaters from different stages in Datansha wastewa-ter treatment plant of Guangzhou were analysed, Monocyclic aromatics and chlorinated hydrocarbons (CHCs) were found to be the principal hazardous pollutants in influent. By the comparison of VOCs in the influent and effluent, it revealed that the removal efficiencies for benzene, toluene, ethylbenzene and xylene (BTEX) were almost 100%, and for several typical CHCs, 79%-89 % . BTEX and the selected CHCs were mostly removed in the bioreaction basin, especially within the anaerobic process. Emissions of hazardous VOCs to the ambient air were also estimated, and the calculation showed that a larger proportion of CHCs were removed by volatilisation than that of BTEX.

对广州大坦沙污水处理厂各工艺阶段污水中挥发性有机物(VOCs)的测试表明,进水中主要有害VOCs为苯系物和卤代烃;进水和出水比较,苯 甲苯、乙苯、二甲苯(合称BTEX) 的去除率接近100%,污水中几种主要卤代烃的去除效率范围为79%—89%.VOCs主要的去除作用发生在生物反应池,特别是厌氧阶段,本研究还对污水处理厂几种典型挥发有机物排放到周围空气中的量进行了理论估计,计算表明卤代烃进入空气中的比例高于BTEX.

A photocatalically active coating made of photocatalyst-type TiO_2 has been introduced.It will soon be able to help to remove NO_x,SO_2,bacteria,and other hazardous pollutants from the air

介绍了以光催化型TiO_2制备的涂料,有望通过这些涂料来消除空气中的NO_x、SO_2、细菌和其他有害污染物。
