采用室内土柱实验法，研究了向土壤中掺入活性炭纤维对地下水硝酸盐氮污染的防治效果。结果表明，将活性炭纤维掺入土壤中，可以强化土壤反硝化作用，防止硝酸盐氮对地下水的污染。这种防治技术简单、有效，并且能增加土壤的肥力和保墒能力。环境效益和经济效益皆佳。
The indoor soil column experiment was used to study the control effect of activated carbon fiber incorporated into the soil on nitrate nitrogen pollution of groundwater. The results showed that the incorporation of activated carbon fiber into the soil could enhance soil denitrification and prevent the contamination of groundwater with nitrate nitrogen. This control technology is simple and effective, and can increase soil fertility and soil moisture capacity. Environmental benefits and economic benefits are good.
