【摘要】：隨著社會(huì)經(jīng)濟(jì)的發(fā)展,人口逐漸增加,城市生活垃圾產(chǎn)量和清運(yùn)量不斷攀升,生活垃圾帶來(lái)的一系列問(wèn)題已成為制約城市發(fā)展的瓶頸。通過(guò)開展垃圾分類減少城市生活垃圾末端處理量、回收資源、改善城市生態(tài)環(huán)境是城市可持續(xù)發(fā)展的迫切要求。我國(guó)自2000年開始探索生活垃圾源頭分類,在多個(gè)城市進(jìn)行試點(diǎn),但是仍然存在很多問(wèn)題。本文首先介紹了國(guó)內(nèi)外城市生活垃圾分類的現(xiàn)狀,指出我國(guó)垃圾分類存在的問(wèn)題。城市居民生活垃圾是城市生活垃圾的主要產(chǎn)生源頭。我國(guó)居民區(qū)生活垃圾量大,成分復(fù)雜,在傳統(tǒng)的混合收集、混合運(yùn)輸、混合處理模式中出現(xiàn)了很多的問(wèn)題。城市生活垃圾處理用地緊張,垃圾問(wèn)題帶來(lái)的環(huán)境問(wèn)題亟待解決。居民區(qū)生活垃圾分類的成功推行對(duì)于城市生活垃圾實(shí)現(xiàn)“無(wú)害化、減量化、資源化”具有重要意義。本文以居民區(qū)為重點(diǎn)研究對(duì)象,分析居民區(qū)垃圾特性,探討我國(guó)生活垃圾分類陷入困境的原因。構(gòu)建居民區(qū)生活垃圾評(píng)價(jià)指標(biāo)體系,提出了五種垃圾分類收集方案,并通過(guò)熵權(quán)物元可拓評(píng)價(jià)模型進(jìn)行方案選擇。以東莞市為例,通過(guò)大量調(diào)查問(wèn)卷進(jìn)行基礎(chǔ)條件研究,結(jié)合評(píng)價(jià)模型對(duì)東莞市居民區(qū)生活垃圾分類收集方案進(jìn)行實(shí)證研究。結(jié)果表明,東莞市居民生活垃圾目前應(yīng)進(jìn)行干濕分離,分為廚余垃圾和其他垃圾兩類。
[Abstract]:With the development of social economy, the population increases gradually, the output of municipal solid waste (MSW) and the quantity of clear transportation are rising, and a series of problems brought by MSW have become the bottleneck restricting the development of the city. It is an urgent requirement for the sustainable development of the city to reduce the terminal disposal of municipal solid waste, recover the resources and improve the ecological environment of the city through the development of garbage classification. Since 2000, our country began to explore the source classification of domestic refuse and carried out pilot projects in many cities, but there are still many problems. This paper first introduces the current situation of domestic and foreign municipal solid waste (MSW) classification, and points out the existing problems of MSW classification in China. Municipal solid waste (MSW) is the main source of municipal solid waste (MSW). There are many problems in the traditional mixed collection, mixed transportation and mixed treatment mode. The disposal of municipal solid waste (MSW) is tight, and the environmental problems caused by MSW are urgent to be solved. The successful implementation of the classification of residential domestic waste is of great significance to the realization of "harmless, reduced and resource utilization" of urban domestic waste. This paper focuses on residential areas, analyzes the characteristics of residential garbage, and probes into the reasons why the classification of domestic wastes in China is in difficulty. In this paper, the evaluation index system of residential solid waste is constructed, and five kinds of garbage collection schemes are put forward, and the scheme is selected by entropy weight matter-element extension evaluation model. Taking Dongguan City as an example, the basic conditions are studied by a large number of questionnaires, and the classification and collection scheme of municipal solid waste (MSW) in residential areas of Dongguan City is studied empirically with the evaluation model. The results show that the household garbage in Dongguan should be separated into kitchen waste and other garbage.
