大气污染物综合排放标准的编制技术方法

我国《大气污染综合排放标准》规定了33种大气污染物的排放限值和执行要求。标准提出了一个污染源必须同时遵守最高允许排放浓度；最高允许排放速率和无组织排放监控浓度限值三项限制指标。以众多企业的排放数据和“最佳实用治理技术”为依据制定排放浓度限值；以环境质量要求和全国大部分地区的中性气象条件为依据，经计算后确定排放速率限值；以污染源周界环境空气浓度达到质量标准要求确定无组织排放限值。经过一定范围的调查检验后，表明该标准具有基本适宜的宽严程度。

Technical method of development the integrated emission standard of air pollutants

The Integrated Emission Standard of Air Pollutants stipulates the requirements of emission of 33 air pollutants,as well as its implementation.Each stationary pollution source must comply with all of three indexes.Among them,the maximum allowable concentration limits are set up based on the emission data from different sources and Best Practical Technology(BPT),the emission rate limits are formulated according to the requirement of environmental quality and the medium meterollogical condition in most areas of Chian,and the control limits of diffusion source are determined by the requirement of ambient air concentration around pollution source,the concentration is based on the requirement of the environmental quality standard.After a careful investigation and observation in certain area,it proves that standard is practical and feasible.
