Good quality of water determines the healthy life of living beings on this earth. The cleanliness of water was interrupted by the pollutants emerging out of several human activities. Industrialization, urbanization, heavy population, and improper disposal of wastes are found to be the major reasons for the contamination of water. Globally, the inclusion of volatile organic compounds (VOCs) and heavy metals released by manufacturing industries, pharmaceuticals, and petrochemical processes have created environmental issues. The toxic nature of these pollutants has led researchers, scientists, and industries to exhibit concern toward the complete eradication of them. In this scenario, the development of wastewater treatment methodologies at low cost and in an eco-friendly way had gained importance at the international level. Recently, bio-based technologies were considered for environmental remedies. Biofiltration-based works have shown a significant result for the removal of volatile organic compounds and heavy metals in the treatment of wastewater. This was done with several biological sources such as bacteria, fungi, algae, plants, yeasts, etc. The biofiltration technique is cost-effective, simple, biocompatible, sustainable, and eco-friendly compared to conventional techniques. This review article provides deep insight into biofiltration technologies engaged in the removal of volatile organic compounds and heavy metals in the wastewater treatment process.
优质的水决定了地球上生物的健康生活。水的清洁度被人类活动产生的污染物所打断。工业化、城市化、人口密集和废物处理不当被认为是水污染的主要原因。在全球范围内，制造工业、制药和石化过程中释放的挥发性有机化合物 (VOCs) 和重金属的存在，已经造成了环境问题。这些污染物的毒性导致研究人员、科学家和工业界对它们的完全消除表示关注。在这种情况下，以低成本和环保的方式开发废水处理方法在国际上变得尤为重要。最近，生物基技术被认为是一种环境补救措施。基于生物过滤的工作已经显示出在处理废水中去除挥发性有机化合物和重金属方面的显著效果。这是通过几种生物来源如细菌、真菌、藻类、植物、酵母等来实现的。与传统技术相比，生物过滤技术具有成本效益高、简单、生物相容性好、可持续和环保等优点。本文综述了生物过滤技术在去除废水中挥发性有机化合物和重金属方面的应用。
