Abstract

Industrialization plays an important role in the growth of a nation. But it is also added to the deteriorating condition of our ecosystem. Pollution, be it aquatic, terrestrial, or airborne, has affected our environment drastically and the surge of industries and growing population plays a major role in it. Innumerable basic and advanced techniques degrade the contaminants in wastewater. Most of these techniques are efficient but have several drawbacks too. The biological technique is one such viable approach in which there are no eminent downsides. This article presents a brief investigation of the biological treatment of wastewater, namely biofilm technology. Recently biofilm treatment technology has garnered a lot of attention due to its efficiency, inexpensiveness, and ease of incorporation into various conventional treatment techniques. A succinct analysis is provided about the mechanism of biofilm formation and its application in various systems in fixed, suspended, or submerged conditions. Details of the application of biofilm technology in lab-scale and pilot-scale treatment of industrial effluents are also discussed. This study is crucial to understand the competency of biofilms and to utilize the idea for further development of the technology for better management of wastewater. Pollutants such as BOD, COD can be removed up to 98 % with the help of Biofilm reactor technologies, making it one of the most efficient systems for wastewater treatment.

生物膜反应器在废水处理中的研究进展:生物膜载体、动力学、反应器、经济及未来展望。

工业化在一个国家的发展中起着重要的作用。但这也加剧了我们日益恶化的生态系统。污染，无论是水生的，陆地的还是空气中的，都极大地影响了我们的环境，工业的激增和人口的增长在其中起着重要作用。无数基本和先进的技术可以降解废水中的污染物。这些技术大多是有效的，但也有一些缺点。生物技术就是这样一种可行的方法，没有明显的缺点。本文介绍了污水的生物处理技术，即生物膜技术。近年来，生物膜处理技术因其高效、廉价、易于纳入各种常规处理技术而受到广泛关注。简要分析了生物膜的形成机制及其在固定、悬浮或浸没条件下的各种系统中的应用。详细讨论了生物膜技术在实验室规模和中试规模工业废水处理中的应用。这项研究对于了解生物膜的能力和利用这一思想进一步发展废水管理技术至关重要。生物膜反应器技术可以去除高达98%的BOD、COD等污染物，使其成为最有效的污水处理系统之一。

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
