摘　　要：随着工业和农业的快速发展,人类活动所产生污、废水中过量的氮磷流入不同水域引起了水体富营养化,而这一现象在灌区也极为常见。生物炭作为一种多孔吸附剂,在富营养水氮磷净化、回收与资源化利用方面具有优越性。为了推动富营养水体的资源化利用,通过简述生物炭吸附氮磷的过程及相关影响因素,阐述了负载金属的生物炭既能降低富营养水体等级又能作为养分载体实现农田资源化利用这一充满前景的观点,并提出废水资源化利用可能是实现农业水土资源协调均衡与农田生产可持续化的重要技术。在此基础上,提出了未来生物炭值得深入探讨与攻关的研究方向,以期为我国废水资源化利用领域的发展提供参考。With the rapid development of industry and agriculture,excessive nitrogen and phosphorus in sewage and wastewater produced by human activities flow into different waters,causing eutrophication of water bodies,which is also very common in irrigation areas.As a porous adsorbent,biochar has advantages in purification,recovery and resource utilization of nitrogen and phosphorus in eutrophic water.In order to promote the resource utilization of eutrophic water bodies,by briefly describing the process of biochar adsorbing nitrogen and phosphorus and related influencing factors,this paper expounded the promising view that metal-loaded biochar can not only reduce the grade of eutrophic water bodies,but also realized the resource utilization of farmland as a nutrient carrier,and proposed that the resource utilization of wastewater may be an important technology to realize the coordination and balance of agricultural water and soil resources and the sustainability of farmland production.On this basis,the future research directions of biochar worthy of in-depth discussion and research were put forward,in order to provide reference for the development of wastewater resource utilization in China.
