在过去的几十年里，水资源的短缺促使人们对废水的观念发生了转变：从废物到有价值的资源。利用废水不仅可以缓解水资源短缺问题，还可以为养分和能源回收提供机会，进一步抵消部分宝贵资源的开采。在建立废水资源回收系统时，应优先考虑所采用的技术和材料，以实现经济上可行和对环境负责的解决方案。生物炭在成本、养分保持和污染物吸附效率等方面的优势为资源回收提供了可能。因此，了解生物炭与资源回收之间的关系，对于开发生物炭在环境修复和废水利用中的应用至关重要。然而，到目前为止，还没有建立生物炭和回收物质之间的相关性的全面审查。在这篇综述中，我们的目的是评估生物炭在废水资源化中的作用。生物质炭可回收的物质主要包括组件、水资源和能源。针对不同的恢复目标，对可行的有效方法进行了分类。特别是通过揭示生物炭生产方法与回收物质之间的相互关系，为生物炭的选择提供指导。并对回收物的再利用和价值进行了全面总结。最后指出了生物炭在水资源回收中存在的问题、存在的局限性和广阔的工业应用前景。这一审查可以提高人们对生物炭水资源回收的各种选择的可能性的认识，并有助于进一步发展和示范废水处理。
Over the past few decades, the shortage of water resource has prompted a shift in human concept about waste water: from waste to valuable resource. Utilizing wastewater can not only mitigate water scarcity, but also provide an opportunity for nutrient and energy recovery, further offsetting part of the exploitation of valuable resources. When establishing resource recovery systems of wastewater, the implemented technology and materials should be preferentially considered in order to achieve economically feasible and environmentally responsible solutions. The advantages of biochar in cost, nutrient retention and pollutant adsorption efficiency endow its possibility for resource recovery. Thus, understanding the relationship between biochar and resource recovery is essential to develop the applications of biochar in environment remediation and wastewater utilization. However, to this date there is no comprehensive review that establish the relevance between biochar and recycled substance. In this review, we aim to evaluate the roles of biochar in resource recovery from wastewater. Recyclable substances with the presence of biochar mainly include components, water resource and energy. Viable and effective methods for different recovered targets are classified. In particular, through revealing the interrelationship between biochar production methods and recovered substances, we try to provide the guideline for biochar selection. The re-application and value of recovered substances are also summarized comprehensively. Moreover, the current problems, existing limitations, and promising industrial application value of biochar in resource recovery from water are also put forward. This review can create awareness about the possibility of various options for resources recovery from water with biochar and contribute to further development and demonstration in wastewater treatment.
