【摘要】：近年来，随着经济的迅速发展，人们的生活水平逐步提高，急剧增加的城市生活垃圾已成为环境污染的一个重要源头，被列为亟待解决的三大环境问题之一。解决垃圾问题的最终目标是使垃圾无害化、减量化和资源化。目前，生活垃圾主要采用卫生填埋、高温堆肥、焚烧和综合利用的方法。目前黑龙江省某管理局生活垃圾清运量约80t/d，中心城区有垃圾填埋场一座，位于第一社区南1公里，距离城镇中心3公里处，占地1.5公顷。垃圾收集过程为垃圾箱收集，只采用简易填埋的方式，严重污染环境。该处理场接近饱和状态，已不能满足城市发展的需要。论文在调研了某管理局生活垃圾的产生量、增长趋势以及处理状况的基础上，针对当地的自然条件、气候条件、地质地貌等特征，，综合考虑经济实力、投资能力、拟建场址条件、垃圾成分、城镇发展对环境的整体要求等，结合国家有关产业政策及该管理局总体规划设想，拟采用卫生填埋工艺，解决当地生活垃圾处理问题。卫生填埋是以传统填埋为基础发展起来的技术，作为生活垃圾最终处理的传统方法之一，垃圾填埋仍然是解决我国大多数生活垃圾的主要方法。填埋场采用分区分层作业方式，设计地下水导排设施。防渗材料采用1.5mm厚的高密聚乙烯（HDPE）防渗膜，防渗膜上、下应该分别采用土工布及钠基膨润土毯保护层对HDPE膜进行保护。在本工程设计中，采用垂直石笼井与场底渗滤液导流层和封场排气层相结合的方式将填埋气体排出，经收集后用于发电。垃圾渗滤液经水平和垂直收集系统收集后，采用MVR工艺处理达标后排放。本课题的实施为改善地区的环境卫生及促进生态城市建设提供了重要保障。
[Abstract]:In recent years, with the rapid development of economy, people's standard of living has been gradually improved. The rapid increase of municipal solid waste has become an important source of environmental pollution, and has been listed as one of the three environmental problems to be solved. The ultimate goal of solving the garbage problem is to make the garbage harmless, reduced and resource. At present, sanitary landfill, high-temperature compost, incineration and comprehensive utilization are the main methods of MSW. At present, a certain administrative bureau in Heilongjiang Province is carrying about 80 t / d of domestic garbage. There is a landfill in the central urban area, one kilometer south of the first community and three kilometers from the center of the town, covering an area of 1.5 hectares. Garbage collection process is garbage collection, only simple landfill, serious pollution of the environment. The treatment field is close to saturation and can not meet the needs of urban development. On the basis of investigating the production, growth trend and disposal status of MSW in a certain administrative bureau, the paper considers the economic strength and investment ability in view of the local characteristics of natural condition, climate condition, geology and geomorphology, etc. The proposed site conditions, refuse composition, the overall requirements of urban development to the environment, combined with the national industrial policy and the overall planning of the administration, the sanitary landfill process is to be adopted to solve the problem of local domestic waste disposal. Sanitary landfill is a technology developed on the basis of traditional landfill. As one of the traditional methods for the final disposal of domestic refuse, landfill is still the main method to solve most of the domestic garbage in China. The ground water guiding and discharging facilities are designed in the landfill by zonal layering operation. 1.5mm thick high density polyethylene (HDPE) impervious film should be used in the impervious material, and the protective layer of geotextile and sodium bentonite blanket should be used to protect the HDPE film under the impervious film. In the design of the project, the landfill gas is discharged by combining the vertical cage well with the leachate diversion layer and the sealing field exhaust layer at the bottom of the field, and used for power generation after collection. Landfill leachate was collected by horizontal and vertical collection system and discharged by MVR process. The implementation of this project provides an important guarantee for the improvement of regional environmental hygiene and the promotion of ecological city construction.
