溶解氧对贾鲁河底泥中氮释放的影响
Effects of Dissolved Oxygen on Nitrogen Release from Jialu River Sediment
摘要
Abstract
[Objective] The aim was to study the effects of dissolved oxygen ( DO) on nitrogen release from Jialu River sediment. [ Method] Based on the current pollution status of Jialu River (in Zhengzhou), through simulation test of original columnar sediment, the effects of dis solved oxygen on nitrogen transformation in Jialu River sediment were analyzed. [ Result ] DO was the main impact factor of nitrogen transfor mation in Jialu River sediment, and different DO concentrations had various effects on the transformation time and efficiency of ammonia nitro gen , nitrite nitrogen and nitrate nitrogen. Under aerobic environment, ammoniation, nitrosification and nitrification were carried out complete ly , and the transformation time of ammonia nitrogen, nitrite nitrogen and nitrate nitrogen was less than that under anaerobic environment, while the transformation efficiency was higher than that under anaerobic environment. [ Conclusion ] The study could provide scientific references for the water pollution control in Jialu River.关键词
