反硝化细菌在水产养殖污水处理中的应用及影响其处理效果的因素分析

摘要

Aquatic productivity is usualy based on the quantity and quality of nitrogen,which plays an important role in aquaculture system.As a serious threat to the aquaculture organisms,accumulated ammonia and nitrite in the aquaculture water should be highly concerned.Aimed at biological nitrogen removal in aquaculture system,the article describes the application of denitrifying bacteria in sewage treatment.And combined with domestic and foreign research results,the article analyzes the various factors affecting the biological denitrification.%氮元素是水产养殖水体中较常见的一种限制初级生产力的营养元素，对水产养殖影响巨大。养殖水体中积累的氨氮和亚硝态氮对水产养殖生物可造成巨大危害，其影响不容忽视。本论文围绕水产养殖废水生物脱氮这一主题，介绍反硝化细菌在污水处理中的应用研究，并结合中外研究成果，分析影响生物反硝化作用的各种因素。
