大气环境防护距离与卫生防护距离确定技术方法对比研究

根据环境影响评价技术导则—大气环境（HJ2.2-2008）等有关规定，对基于SCREEN3模型的大气环境防护距离确定技术方法进行研究，对比分析了现行的卫生防护距离和HJ2.2-2008规定的大气环境防护距离确定方法的差异，论述了各行业卫生防护距离标准仍执行的可行性，进一步探讨了大气环境防护距离确定存在的问题与技术解决方案，提出了尽快制定无组织排放源强确定技术方法规范、各行业大气环境防护距离标准的建议，为环境评价与保护工作提供参考。

Comparative study on technology methods determining atmospheric environment and hygienic prevention distances

According to the guideline for atmospheric environment evaluation technology (HJ 2.2-2008), the technology method determining atmospheric environment prevention distance was analyzed based on the SCREEN3 model, and the differences were summarized with hygienic prevention distance. The feasibility of living hygienic prevention distance criterion was discussed, and the living problems and the way to solve the problems were also brought up. The suggestions determining uncontrollable emission source technology criterion and establishing atmospheric environment prevention distance criterion in various industries were put up, which can provide the references for environment evaluation and environment protection.
