摘要

高速厌氧消化器由于其高负荷能力、减少碳足迹和降低污泥产量而备受关注。其中,最优选的是上流式厌氧污泥床(UASB)反应器。然而,仍有一些悬而未决的问题阻碍了这项技术的广泛应用。从颗粒污泥床开始,培养微生物群落是UASB反应器工作的主要基础。这些微生物群落在废水处理中起着主要作用,因此需要研究控制它们生长、存活和分布的因素。因此,分析颗粒污泥的粒度、颗粒密度和缩微胶片特性,以提高反应器的效率,似乎是非常重要的。这使得世界各地的科学家都在关注颗粒的形成因素,以及颗粒如何对废水处理做出贡献。本研究介绍了最先进的技术。

Granules as Precursors in the Working of Upflow Anaerobic Sludge Blanket Reactor: A Review on the Impacts of Granulation
High-rate anaerobic digesters are of great concern these days—due to their high loading capacity, reduced carbon footprints and lower sludge production. Among them, the most preferred is the upflow anaerobic sludge blanket (UASB) reactor. However, there are still unresolved issues that inhibit the widespread of this technology. To start with the granular sludge bed fostering the microflora forms the prime seat in the working of UASB reactors. These microflora have a predominant role in the treatment of wastewater, hence the factors governing their growth, survival, and distribution are to be studied. Thus it seemed as due important to analyse the granular sludge for its particle size, particle density, and microfilm characteristics, to enhance the reactor’s efficiency. This has made scientists across the world put an eye on factors that shape the granules and how the granules contribute to wastewater treatment. The state-of-the-art is presented in this study.

期刊介绍: Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
