IMITATION EXPERIMENTS OF NITROGEN NITRATE POLLUTION MECHANISM AND THE METHOD OF PREVENTION AND TREATMENT OF GROUNDWATER POLLUTION IN HOHHOT

摘要

During the last two decades, groundwater (phreatic water) nitrate pollution is very serious in many cities of China, so that the study of nitrogen pollution mechanism, prevention and treatment has important significance. This paper deals with the appraisement of regional groundwater nitrogen intrate pollution trends, the regularity of nitrogen nitrate transformation and transportation in the geological environment system and puts forward methods of groundwater nitrogen nitrate pollution prevention and treatment.
