铅锌冶炼厂大气污染主要模式及防治

THE MAIN PATTERNS AND PREVENTION OF AIR POLLUTION FROM LEAD AND ZINC SMELTERIES

为了探讨铅锌冶炼厂排放废气对周围环境污染情况,我倪对Cu, pb, Zn, Cd在冶炼广周围土壤、植物中的分布、迁移与累积规律进行了研究,揭示了我国亚热带地区铅锌冶炼厂大气污染规律的模式,为了实行工农联合、统一规划、合理布局、综合防治提供了科学依据。

The forms and degree of air polluting surroundings are different due to the differences of regional climatic conditions resulting from different natural geographical environments. There are mainly three air pollution patterns, 1) wind-rose pattern, 2) air pollution extent pattern, and 3) topography pollution pattern. According to the law that smelteries pollute their surroungdings in subtropic regions with lead and zinc smelteris in China, three types of plants (sod, castor and broadleeaf trees) should be planted according to the pollution degree.
