| 摘 要： | [目的]研究溶解氧对贾鲁河底泥中氮释放的影响。[方法]结合贾鲁河（郑州段）污染现状,通过原始柱状底泥模拟试验,研究了溶解氧对贾鲁河底泥中氮转化的影响。[结果]溶解氧是影响贾鲁河底泥中氮转化的主要因素,不同溶解氧浓度对氨氮、亚硝酸盐氮、硝酸盐氮的转化时间和效率的影响不同。好氧环境条件下,氨化、亚硝化、硝化作用进行较彻底,氨氮、亚硝酸盐氮、硝酸盐氮的转化时间少于厌氧环境,其转化效率高于厌氧环境。[结论]该研究为贾鲁河水污染治理提供了科学参考。

| 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 dissolved oxygen on nitrogen transformation in Jialu River sediment were analyzed.[Result]DO was the main impact factor of nitrogen transformation in Jialu River sediment,and different DO concentrations had various effects on the transformation time and... |
