摘要:

利用引进的CWO处理技术及其200 L/d小型工业试验装置,对我国焦化、造纸、生物制药等十多种行业的高浓度工业有机废水进行处理试验研究,结果表明CWO技术及装置对处理我国高浓度工业有机废水具有良好的适用性。在昆明自主设计、制造、集成建设和运行了一套20 m3/d工业应用装置,完成了对该技术的国产化研究与示范工程。该工业化应用装置对造纸黑液、焦化废水等两种高浓度生化难降解工业有机废水具有良好的净化处理性能,废水中的CODCr,NH3-N等的去除率均达99%以上,可以使废水经处理后连续稳定地达标排放,并具有较好的经济性。

《环境科学与工程前沿(英文)》 2016年 第10卷 第3期   页码 513-521 doi: 10.1007/s11783-015-0777-y

摘要: The successful operation of any type of hydrogen-producing bioreactor depends on the performance of the microorganisms present in the system. Both substrate and partial gas pressures are crucial factors affecting dark fermentation metabolic pathways. The main objective of this study was to evaluate the impact of both factors on hydrogen production using anaerobic granular sludge as inoculum and, secondly, to study the metabolic shifts of an anaerobic community subjected to low partial gas pressures. With this goal in mind, seven different wastewater (four synthetic media, two industrial wastewater, and one domestic effluent) and the effect of applying vacuum on the systems were analyzed. The application of vacuum promoted an increase in the diversity of hydrogen-producing bacteria, such as , and promoted the dominance of acetoclastic- over hydrogenotrophic methanogens. The application of different media promoted a wide variety of metabolic pathways. Nevertheless, reduction of the hydrogen partial pressure by application of vacuum lead to further oxidation of reaction intermediates irrespective of the medium used, which resulted in higher hydrogen and methane production, and improved the COD removal. Interestingly, vacuum greatly promoted biogenic hydrogen production from a real wastewater, which opens possibilities for future application of dark fermentation systems to enhance biohydrogen yields.
