【摘要】 厌氧废水处理是一种把废水的处理和能源的回收利用相结合的低成本的废水处理技术。作为一种适合我国国情的废水处理技术，厌氧生物处理技术在水污染控制领域有着广阔的发展前景。 UASB反应器是目前应用最为广泛的厌氧处理工艺，已成功地应用于处理多种不同成分、浓度的污水。接种污泥的颗粒化是UASB反应器启动的目标和启动成功的标志，本课题通过在UASB反应器的启动过程中投加凹凸棒石粘土和未投加凹凸棒石粘土的对比启动实验发现，投加凹凸棒石粘土能够缩短UASB反应器内接种污泥的颗粒化进程，从而加速了反应器的启动过程，此外反应器的运行状况也得到了一定程度的改善和提高。 本文结合污泥颗粒化的新理论对投加凹凸棒石粘土后反应器内污泥颗粒化加速的机理提出了相应的解释。更多还原

【Abstract】 Anaerobic wastewater treatment is a sort of low cost technology which integrates the disposal of wastewater with energy recycle. The technology fits the present situation of our country well. Anaerobic wastewater treatment technology will be with great prospects in the water pollution control area.One of the anaerobic treatment processes used in the world is the upflow anaerobic sludge bed (UASB) reactor. The reactor has succeeded in treating wastewater with various ingredient and strength. Granulation of inoculation sludge is the goal of UASB reactor’s startup process and symbol of successful startup. In this study, two experiments are done. In one experiment some attapulgite clay is added into the UASB reactor during the startup process. While the other experiment is the control experiment without the addition of attapulgite clay. By the contrast, it was found that the addition of attapulgite clay in the UASB reactor could shorten the granulation process of the inoculation sludge. Thus, the startup process is accelerated. The improvement of UASB reactor’s performance has also been observed.A new theory for the mechanism of sludge granulation, namely proton translocation-dehydration theory, was introduced in this paper. By some experiments, the mechanism of granulation acceleration in the UASB reactor with additional attapulgite clay is explained.更多还原
