废物资源的功能化技术及其意义

The Technologies and Meanings of Waste Resources Functionalization

功能化是废物资源化的高级阶段,对循环经济有重大的促进作用。利用废物资源研制腐植酸是农用资源化和功能化的一个重要渠道,腐植酸可广泛应用于肥料系列产品的生产。本文在总结国内外研究成果的基础上介绍了与腐植酸有关的几种肥料新功能:源头控污、节资节能、施肥节水和施肥防病。

Funcfionalization is the advanced phase of waste reutilization, and it promotes greatly the circular economy. Manufacturing humic acid from waste resources is an important approach of waste reutilization in agriculture and functionalization. In this paper, some new functions of the fertilizers containing humic acid are introduced, such as controlling pollution at beginning, saving nature resources and energy sources, and saving water and preventing diseases by fertilization.
