Pollution is a major concern of the modern era as it affects all the principal aspects of the environment, especially the hydrosphere. Pollution with heavy metals has unequivocally threatened aquatic bodies and organisms as these metals are persistent, non-biodegradable, and toxic. Heavy metals tend to accumulate in the environment and eventually in humans, which makes their efficient removal a topic of paramount importance. Treatment of metal-contaminated water can be done both via chemical and biological methods. Where remediation through conventional methods is expensive and generates a large amount of sludge, biological methods are favoured over older and prevalent chemical purification processes because they are cheaper and environment friendly. The present review attempts to summarise effective methods for the remediation of water contaminated with heavy metals. We concluded that in biological techniques, bio-sorption is among the most employed and successful mechanisms because of its high efficacy and eco-friendly nature.
污染是现代社会的主要关注点之一，因为它影响着环境的所有主要方面，尤其是水圈。重金属污染无疑威胁着水生生物和生态系统，因为这些金属具有持久性、不可生物降解性和毒性。重金属往往会在环境中积累，最终进入人体，因此有效去除重金属成为一个至关重要的问题。受污染水的处理可以通过化学和生物方法来进行。传统方法修复成本高，会产生大量污泥，因此与旧的、常见的化学净化工艺相比，生物方法更受欢迎，因为它们更便宜且环保。本综述试图总结有效去除受重金属污染水的方法。我们得出结论，在生物技术中，生物吸附是应用最广泛、最成功的机制之一，因为它具有高效性和环保性。
