腐植酸是一类重要的肥料、农药缓释剂,水处理剂,在我国新农村的建设中发挥着重要的作用;但同时发现天然水体中的水生腐植酸在饮用水消毒方式不当时,会产生氯仿等致癌性的有毒副产物(THMs)。本文在阐述饮用水水生腐植酸深度处理的基础上,提出了采用生态配伍的施肥、撒药以及治水方式,避免残留农药衍生水生腐植酸副产物及生物链效应等腐植酸使用中新的注意点。
Humic acid is an important kind of fertilizer, pesticide slow-release agent and water treatment agent, which play an important role in the construction of new rural areas in our country. But at the same time, it is found that when aquatic humic acid in natural water is not properly disinfected in drinking water, Produces toxic carcinogenic by-products (THMs) such as chloroform. Based on the deep treatment of aquatic humic acid in drinking water, this paper puts forward the new fertilization, spraying and water treatment methods to avoid the pesticide-derived aquatic humic acid by-product and bio-chain effect and other new points of attention .
