摘要
化肥和其他工农业化学品的大量使用导致过量含NO_(3)^(-)废水排放到自然界中,对环境和人类健康构成了严重威胁。光催化水中NO_(3)^(-)还原技术以其高效能、低能耗和广泛的适用性被认为是一种极具应用前景的NO_(3)^(-)无害化处理方法。本文详细阐述了光催化水中NO_(3)^(-)还原的机理和主要产物,总结了常用的光催化剂类型,介绍了光催化过程中的影响因素;并对光催化NO_(3)^(-)还原技术当前面临的主要挑战及其未来的发展前景进行了深入讨论和展望。
The extensive use of chemical fertilizers and other industrial and agricultural chemicals has led to the discharge of excessive nitrate wastewater into nature,posing a serious threat to the environment and human health.Photocatalytic nitrate reduction technology is considered to be a promising,harmless treatment method for nitrate due to its high efficiency,low energy consumption and wide applicability.In this paper,the mechanism and main products of nitrate reduction in photocatalytic water are described in detail.The commonly used photocatalyst types are systematically reviewed,and the influencing factors in the photocatalytic process are introduced.In addition,the main challenges faced by photocatalytic nitrate reduction technology are comprehensively analyzed,and its future development prospects are discussed and prospected.
