In this paper, the harmful effect, source and conversion of nitrogen pollutionof water are briefly reviewed. A conclusion is obtained that ammonia in "Integra-ted Wastewater Discharge Standard" should be replaced with total nitrogen in orderto limit nitrogen discharge in wastewater and to achieve "Environmental QualityStandard for Surface Water". Nitrogen removal from wastewater can result inlimiting nitrogen discharge, and this process can be achieved by means of biologicalwastewater treatment, especially oxidation...
