摘要
本文简述了水体氮污染的危害、来源及其转化。从理论上分析了我国《污水综合排放标准》中应以总氮代替氨氮作为限制污水排氮量的一项指标,以实现《地面水环境质最标准》,避免出现水体氮污染现象。污水脱氮可达到限制污水排氮暈的目的,这一过程的实现可通过污水生物处理方法,特别是氧化渠处理技术来完成。
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 ditches.
