摘要
垃圾焚烧电厂垃圾坑主要作用是储存垃圾,垃圾在储存和发酵过程中会产生渗沥液,渗沥液是一种高浓度、成分复杂的特殊污染废水;渗沥液中的有机物含量很高,还掺杂大量有毒物质,如重金属、致癌物、微生物等,能够对地下水、周边土壤和大气造成严重的污染,会导致土壤的富营养化、地下水质的恶化,甚至直接危害人们的身体健康。有效保障垃圾坑混凝土结构抗渗性能至关重要。
The main function of the Incineration power plant garbage pit is to store garbage.During the storage and fermentation process of garbage,leachate will be produced.The leachate is a kind of special polluted wastewater with high concentration and complex composition;The organic matter content in leachate is very high,and it is also mixed with toxic substances such as heavy metals,carcinogens,microorganisms,etc.,which can cause serious pollution to groundwater,surrounding soil and atmosphere,lead to Eutrophication of soil,deterioration of groundwater quality,and even directly endanger people's health.It is crucial to effectively ensure the impermeability performance of concrete structures in garbage pits.
