摘要

含水层中的地下水是最重要的可再生自然资源之一。它为90%以上的农村人口提供饮用水。大部分生活和工业垃圾都在露天垃圾场处理。结果，地下水受到污染，水质变差。世界各地都在使用许多治疗策略来解决这个问题。在本研究中，我们调查了印度南部一个工业城市的地下水特性，并使用天然生物混凝剂处理了受污染的地下水。采用罗汉果（Jackfruit peel）、苦瓜籽（Momordica charantia）、香蕉花叶（Musa paradisiaca）和犬齿草（Cynodon dactylon）作为环保型生物混凝剂（飞毛草）。这些混凝剂能很好地去除浊度，同时还能保持水的pH值稳定。此外，这些天然混凝剂可降低BOD、COD和盐分水平。地下水经过处理后可用于家庭用途。因为这是一种低成本、环保的方法，所以广大民众都能负担得起。

Environmentally-Friendly Bio-Coagulants: A Cost-Effective Solution for Groundwater Pollution Treatment

Groundwater in aquifers is one of the most significant renewable natural resources. It provides drinking water to more than 90% of the rural population. The majority of domestic and industrial garbage is disposed off in open dumping yards. As a result, groundwater becomes contaminated and of poor quality. Many therapy strategies are being used in various regions of the world to address this issue. We investigated the groundwater properties in a section of an industrial city in southern India and treated the contaminated groundwater using natural bio-coagulants in this study. Artocarpus heterophyllus (Jackfruit peel), Momordica charantia (Bitter gourd seed), Musa paradisiaca (Banana blossom leaf), and Cynodon dactylon were employed as eco-friendly bio-coagulants (Scutch grass). These coagulants are good at removing turbidity while also keeping the pH of the water stable. Furthermore, these natural coagulants lower BOD, COD, and salt levels. Groundwater can be utilised for home purposes after treatment. Because it is a low-cost and environmentally friendly approach, a vast population can afford it.

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.
