新鲜渗滤液作为老龄渗滤液处理厂生化脱氮碳源的工程应用研究OACHSSCD

A landfill leachate treatment plant has carried out a special engineering test of"fresh leachate as a supplementary carbon source for aging leachate treatment"with resource recycling as the core idea.During the test,the focus was on exploring the optimal mixing ratio of fresh leachate delivery and aging leachate.At the same time,the potential correlation between the actual preparation volume of fresh leachate under different alkalinity conditions and the total nitrogen removal rate of the Membrane Bio-Reactor(MBR)system and the pH value of the biochemical reaction tank was accurately quantified,forming a parameter matching scheme that can directly guide operation.After a year of continuous operation test and data verification,the project was finally completed by laying a dedicated delivery pipeline,realizing the role transformation of fresh leachate from"pollutant to be treated"to"high-quality carbon source",and successfully constructing a long-term and engineering application system for carbon source supplementation in aging leachate,providing replicable and popularizable technical paradigm for the treatment of aging leachate in similar landfills.
