DETERMINATION OF TECHNOLOGICAL PARAMETERS FOR MUNICIPAL SOLID WASTE TREATMENT BY AEROBIC BIOREACTOR TECHNOLOGY
-
摘要: 输氧抽气技术是基于好氧降解原理对垃圾填埋场中固体废弃物实施原位处理的先进环保技术。采用该技术对垃圾填埋场中固体废弃物减量化研究,总结了技术应用中的关键参数:有效影响半径,最佳真空度等。结果表明抽气流量大小与影响半径密切相关,抽气影响半径建议取20~25 m,抽气系统最优负压为20 k Pa,同时在技术应用过程中应保证垃圾场表层覆盖层的密封性能,尽量减少空气的渗入。输氧抽气技术在垃圾场的成功实施为同类型场地治理提供工程技术参考。Abstract: Aerobic bioreactor is an in-situ technology for municipal solid waste ( MSW) treatment. The paper presents the determination of major parameters for MSW disposal by aerobic bioreactor through on-site tests including effective radius and system vacuum. The results show that the effective radius is between 20 ~ 25 m,the vacuum of the system is about 20 kPa, which provide assistant to the similar projects.
