中文摘要:用自行设计的臭氧曝气装置对厌氧污泥进行臭氧曝气试验,在曝气时间分别为0、10、20、30、40、50min时取样测定各种形态氮素含量。结果表明,厌氧污泥随臭氧曝气时间的不同对氮素形态及含量有显著影响。总氮、总凯氏氮、溶解性凯氏氮、铵态氮、亚硝态氮、颗粒态有机氮、颗粒态总氮均随曝气时间延长而减少,连续曝气50min后,分别降低124.76、232.51、11.45、191.28、4.35、221.06、286.06mg/L,均达到显著性差异水平(P<0.05);可溶态总氮、硝态氮、溶解态有机氮随曝气时间延长而增加,持续臭氧曝气50min,分别增加161.29、29.42、179.83mg/L,与初始质量浓度相比,均达到显著性差异水平(P<0.05)。

Abstract:In order to study the influences of different durations of ozone aeration on the nitrogen content and form transformation in anaerobic sludge, the experiment was conducted with self-designed apparatus, with six different durations of ozone aeration, 0, 10, 20, 30,40, 50min, respectively, sampling and measuring content of nitrogen in different forms. The results showed that different durations of ozone aeration remarkably affected the nitrogen content in different forms in wastewater system. Specifically, the content of total nitrogen, Kjeldahl nitrogen, soluble Kjeldahl nitrogen, ammonium nitrogen, nitrite nitrogen, particulate organic nitrogen and particulate total nitrogen, showed significant decline trend with magnitudes of 124.76, 232.51, 11.45, 191.28, 4.35, 221.06 and 286.06mg/L (P<0.05), respectively. By the contrary, the content of soluble total nitrogen, nitrate nitrogen and dissolved organic nitrogen showed upward trend, which were increased by 161.29, 29.42 and 179.83mg/L at the end of 50min(P<0.05), respectively.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
