摘要
隨著經(jīng)濟(jì)的迅速發(fā)展及工業(yè)化與城市化進(jìn)程的加快,城市生活垃圾急劇增多。垃圾污染環(huán)境,對城市居民的健康和生存構(gòu)成了嚴(yán)重威脅,已成為社會一大公害,因此,對垃圾的處理刻不容緩。傳統(tǒng)的垃圾填埋技術(shù)已遠(yuǎn)遠(yuǎn)滿足不了社會對保護(hù)環(huán)境的要求,衛(wèi)生填埋是在傳統(tǒng)垃圾填埋技術(shù)基礎(chǔ)上發(fā)展起來的處理城市生活垃圾的較為理想的方法。現(xiàn)代衛(wèi)生填埋場是一項相當(dāng)復(fù)雜的系統(tǒng)工程,涉及許多方面內(nèi)容。根據(jù)收集到的資料,對城市生活垃圾特性、垃圾填埋場的功能和構(gòu)造、垃圾填埋場的規(guī)劃、選址及勘察、垃圾滲濾液、防滲工程、垃圾力學(xué)等諸多方面分別進(jìn)行了闡述。
衛(wèi)生填埋是目前及今后相當(dāng)長的時期內(nèi)我國城市生活垃圾處理的主要方式。但按我國衛(wèi)生填埋技術(shù)、污染控制標(biāo)準(zhǔn) ,目前國內(nèi)尚沒有垃圾填埋場能全部達(dá)到要求 ,多為準(zhǔn)衛(wèi)生填埋場。其運(yùn)行后 ,對周圍的大氣及水體、土壤等環(huán)境將產(chǎn)生一定影響。
?現(xiàn)代衛(wèi)生填埋工程是一種安全、有效、有控制地處理城市固體廢棄物的方法,其涉及眾多學(xué)科,屬于環(huán)境安全、生態(tài)安全、工業(yè)安全、衛(wèi)生安全共同關(guān)注的問題。城市及工業(yè)廢料的衛(wèi)生填埋工程目的是實現(xiàn)減量化、無害化和資源化,形成一個安全、有效、嚴(yán)格控制、環(huán)境生態(tài)保護(hù),經(jīng)濟(jì)化、無害化、資源化科學(xué)發(fā)展的循環(huán)體系。

Abstract
With the rapid development of economy and urbanization and industrialization, municipal domestic refuse increases quickly and the environment has been polluted. The refuse has done great harm to the society, and threatened our health and living conditions. Therefore, some measures should been taken peremptorily. However, The tradition rubbish is filled burying a technology already having been satisfied with over without end, society protects the environment request face to face, hygiene fills in to bury the comparatively ideal method being that the rubbish fills the treatment city house refuse developing on burying the technology basis in tradition. That modern hygiene is filled burying field is pretty complicated one system engineering, relates to content in many aspects. According to collecting the data arriving at, characteristic property, the rubbish have filled the function and structure burying field , the rubbish has filled the plan , selections location and reconnaissance burying field , rubbish a lot of aspect such as percolating and filtrating liquid , defending against to the project , rubbish Mechanics ooze has been in progress respectively to city house refuse to expound.
Sanitary landfill is one of MSW disposal methods in the present and the future of China. According to the national standards of sanitary landfill technology and pollution controlling, home landfills cannot meet all the standards and are quasi-sanitary landfills. After a landfill has run, it will affect the atmosphere, water and soil. Atmospheric pollution by landfill gas is a very important aspect.
Modern sanitary dumping engineering is a safe, effective and controllable method for dumping urban solid wastes, which concerns many disciplines involving environmental safety, ecological safety, industrial safety and sanitary safety. The goal of sanitary dumping of urban solid wastes is to compress the total amount, to make them less hazardous, and to make them to be a resource, so as to form a circulating system of scientific development. The system is safe, effective, strictly controllable, and environmental
Key words: Sanitary landfill, Municipal refuse, Percolate
