原位好氧稳定化技术在填埋场治理中的应于——以新会区陈腐垃圾填埋场为例

Application of In-Situ Aerobic Stabilization Technology in Landfill Treatment——Taking The Old And Decayed Garbage Landfill in Xinhui District As An Example

目前生活垃圾填埋场治理有较多的治理技术,原位好氧稳定化处理技术以其独特的优势脱颖而出。传统厌氧型垃圾填埋场,通过厌氧生物作用产生含甲烷的填埋气体,而且填埋垃圾中的有机物降解完成需50年以上,同时存在渗滤液处理难度大、封场后维护监管期长、风险大、费用高以及不利于场地及时复用等问题。由于填埋场甲烷浓度较高,长期存在爆炸燃烧的潜在风险,不适于对公众开放。以上问题的长期存在,使得场地开发利用或建造湿地公园时就存在长期的环境与安全隐患,并将产生长期的运行维护与管理任务,需要在这些方面长期投入费用。原位好氧稳定化技术能够在避免以上问题的出现,同时还能够加快垃圾堆体降解使得填埋场达到稳定的状态。

At present,there are many treatment technologies for the treatment of domestic waste landfills,and the in-situ aerobic stabilization treatment technology stands out with its unique advantages.Traditional anaerobic landfill sites generate methane containing landfill gas through anaerobic biological processes,and the degradation of organic matter in landfill waste takes more than 50 years.At the same time,there are problems such as difficult leachate treatment,long maintenance and supervision period after closure,high risk,high cost,and unfavorable for timely reuse of the site.Due to the high concentration of methane in landfills,there is a potential risk of long-term explosion and combustion,making them unsuitable for public access.The long-term existence of the above problems has led to environmental and safety hazards during the development and utilization of the site or the construction of wetland parks,which will result in long-term operational maintenance and management tasks,requiring long-term investment in these areas.In situ aerobic stabilization technology can avoid the above-mentioned problems and accelerate the degradation of garbage piles to achieve stable landfill conditions.
