The microbial community analysis and performance of an anaerobic ammonium oxidation system treatment with different concentrations of ammonium wastewater

指導教授 : 黃郁慈

摘要


近年來全球自然界中氮平衡受到之影響愈來愈大,主要聚焦都在於高科技產業發展蓬勃,連帶其中可能含有大量高含氮物質之製程廢水,但除了高科技製程廢水,在含氨氮廢水比例中,屬於低氨氮排放的生活(都市)污水也占了將近一半的比例,重要性仍不容小覷,因此本研究欲探討含氮廢水生物處理法,其中之厭氧氨氧化菌,在不同氨氮濃度條件下之菌相,主要分析培養於中高濃度之氨氮廢水與低氨氮濃度廢水之厭氧氨氧化菌菌種變化,同時探討各氨氮濃度階段之廢水處理表現與培養條件控制造成之影響。 本研究同時使用實驗室自行架設之批次式反應槽模組進行實驗,實驗條件主要以不同氨氮濃度之廢水進行培養,結果得知,使用本研究之模組進行實驗,能得到快速的污泥活性啟動時間與環境條件控制,且使用間歇中斷氧氣供應與反應槽攪拌轉速控制,能夠在保持厭氧氨氧化活性下,有效的抑制硝化作用,進而控制總氮出流水水質,並提高廢水中氨氮處理效率。 由菌相結果得知,Candidatus Brocadia anammoxidans、Candidatus Brocadia sinica,兩個菌種在低氨氮濃度廢水(250 mg/L)以下,具有較良好之生長活性,與其他階段相比相對比例具有明顯的差異。

並列摘要


Over the last few years, the nitrogen balance has been affected globally because of the developments in high-tech industries which dispose nitrogenous substances into the wastewater. Aside from that, emissions from urban sewage also account for nearly half of the overall amount disposed. This study aims to explore the application of biological process on treatment of nitrogenous waste, specifically the growth of anaerobic ammonium oxide bacteria under different concentrations of ammonia nitrogen. The purpose of this study is to analyze changes in the growth of the bacteria in response to high or low concentrations of ammonia nitrogen present in the wastewater and discuss the effect of wastewater treatment performance and culture condition control in ammonia nitrogen concentration stage. The current study attempts to use a setup of Anammox-SBR to achieve the purpose. The experimental conditions are carried out in different concentrations of ammonia nitrogen. The reactor used in this experiment provides a quick start time, environmental condition control for sludge activity, make use of intermittent interruption of oxygen supply and controlled reaction tank stirring speed to maintain anaerobic ammonium oxidation activity, effective inhibition of nitrification, controlled total effluent water quality and improved wastewater treatment efficiency. Results showed that Candidatus Brocadia Anammoxidans and Candidatus Brocadia Sinica have the best growth activity at the low ammonia nitrogen concentration (250 mg/L) and the relative proportion of the two bacteria were significantly higher than other stages.
