Abstract

A pilot-scale bio-filter coupled nitrification and CANON was started up to remove iron, manganese and ammonia nitrogen from groundwater in a plant, and the main removal route of ammonia nitrogen was analyzed. The experiment showed that the bio-filter could be started up successfully and achieved stable operation after 164 days of culture development. The value of △NH-N/△NO-N was 1.49, and the oxidation and removal of Fe(Ⅱ), Mn(Ⅱ), and NH-N were (9.87±1.17), (2.25±0.06), and (1.51±0.06) mg·L, respectively. The calculation based on the quantitative relationship between nitrogen conservation and dissolved oxygen (DO) measurement indicated that the contribution of CANON to NH-N removal was 33.48%-38.87%, and the average ratio of ammonia nitrogen removal amount to DO was 1:3.79-1:3.94. The removal ratio of ammonia nitrogen was lower with lower temperature.

摘要

启动了一个中试规模的生物滤池，将硝化作用和厌氧氨氧化耦合起来，以去除某工厂地下水中的铁、锰和氨氮，并分析了氨氮的主要去除途径。实验表明，经过164天的培养发展，该生物滤池能够成功启动并实现稳定运行。△NH-N/△NO-N的值为1.49，Fe(Ⅱ)、Mn(Ⅱ)和NH-N的氧化去除量分别为(9.87±1.17)、(2.25±0.06)和(1.51±0.06)mg·L。基于氮守恒与溶解氧(DO)测量之间的定量关系进行计算表明，厌氧氨氧化对NH-N去除的贡献率为33.48%-38.87%，氨氮去除量与DO的平均比例为1:3.79-1:3.94。温度越低，氨氮的去除率越低。
