不同消毒方式下的微生物群落组成及对管段腐蚀的影响
Effect of Microbial Communities Composition on Water Supply Pipelines Corrosion under Different Disinfection Methods
摘要
Abstract
Corrosion-induced problems in the water network and the choice of disinfection methods are of increasing concern.The role of the dominant flora in the biofilm in the corrosion process under different disinfection methods was studied in this paper.High-throughput sequencing was used to characterise and characterise the biofilm bacterial community in each tube section of the pilot network system.The results showed that Hyphomicrobium,a denitrifying bacterium,was the dominant genus in the UV disinfection mode and inhibited corrosion in the tube sections.In chlorine disinfection,Propionivibrio is the dominant genus,which to a certain extent promotes the formation of metal pitting.In the UV-chlorine disinfection method,most of the genera were similar in composition to the initial UV disinfection method,with denitrifying bacteria being the dominant genus,but as the length of operation increased,Propionivibrio became the dominant genus.Thus,the use of UV or UV-chlorine as a disinfection method has an inhibitory effect on the corrosion of the pipe section.关键词
