An Overview on the Remediation Technology for the Nitrogen Polluted Groundwater

Based on the analysis of the groundwater nitrogen contamination recourse and hazards as well as the urgency requirement of groundwater contamination remediation scientifically and in due time, this paper the sources and hazards of the nitrogen (nitrate, nitrite and ammonia)in the drinking water and groundwater were investigated firstly. Then, a detailed overview of different nitrogen contaminated groundwater remediation Technologies (physical, chemical and biologic) were expounded amply and their advantages and disadvantages were analyzed and compared respectively and the development trend is discussed briefly. At last, the biological remediation technology was identified as the optimal one and the application idea was put forward.
