【摘要】 “垃圾是地球上唯一增长的资源”。随着科技的发展、社会的进步,生活垃圾资源化已逐渐成为社会共识。解决垃圾资源化利用问题,可以有效解决垃圾污染所带来的危害并有效缓解资源短缺问题。本文选取湖南省平江县和宁乡县7个村(社区)作为研究区域,进行了村民垃圾资源化利用意愿、垃圾分类类型与数量调查、开展了分类垃圾资源化利用模式的研究,主要研究结果如下:1、对村民资源化认知程度做了问卷调查,问卷调查结果表明:平江县农户生活垃圾分类率较高的是厨余类、金属类和危险废物类,分别为83.92%、91.26%、95.3%。村民对资源化了解程度一般,非常了解的人只占6.18%,一般了解和比较了解的人分别为32.54%、18.80%;愿意支付环卫费用的只占7.20%,表明该地区村民资源化认知还需大力提升。2、本文还对调查区域各村生活垃圾分类现状、处理现状、资源化现状进行了调查,并对各村的垃圾组分进行了实地调查,结果表明农村的经济水平越高,垃圾产量越高;各镇集镇的垃圾产量明显高于各镇所辖村;各村有机垃圾的百分比最高,基本超过40%,其次是可回收利用垃圾、建筑垃圾,表明调查区域垃圾资源化潜力较高。3、农村生活垃圾资源化模式的建立与可行性研究及对策。依据平江县、宁乡县现有的垃圾分类方式对各类垃圾采取相应资源化处理方式,从而构建相应的资源化模式:分别从模式的目标、主体、功能对模式进行了分析并构建,并且针对不同垃圾类别产量和特性,对有机垃圾构建了户或村循环模式;建筑垃圾构建了镇循环模式;可回收利用垃圾构建了县循环模式,最后对资源化模式进行了经济效益分析,论证了该模式在技术、市场、经济方面的可行性。更多还原

【Abstract】 "Waste is the only growing resource on the earth".With the development of science and technology and the progress of society,the resources of living garbage has gradually become a social consensus.To solve the problem of waste resource utilization,it can effectively solve the harm caused by waste pollution and effectively alleviate the shortage of resources.The villagers’ intention of household solid waste resource utilization,garbage classification type and quantity were investigated and resource utilization model on rural household solid waste were studied in seven villages(communities)in Pingjiang county and Ningxiang County in Hunan province in this paper.The results were as follows:1.A questionnaire survey is conducted on the cognition level of villagers’ resources.The results of questionnaire survey show that the classification rate of household solid waste in Pingjiang county is high,which is 83.92%,91.26% and 95.3% respectively.The villagers generally have a general understanding of resources,and only 6.18% of them know very much.People who generally know and know more are 32.54% and 18.80%.Only 7.20% of them are willing to pay for sanitation,which indicates that the villagers’ resource cognition needs to be improved.2.The status of the village household solid waste classification,treatment,resources were investigated on-the-spot,the results show that rural economic level is higher,the higher the yield of garbage;garbage yield in town was significantly higher than in rural,;the percentage of organic waste was the highest,more than 40%,followed by Recyclable solid waste and construction waste,regional waste resource potential is higher.To provide the basis for the establishment of the ecological system for the utilization of rural domestic household solid waste resources.3.The models,feasibility and countermeasure of resource utilization of rural household solid waste were studied.the respective modes of resource utilization from its aim,subject and function were built according to the current refuse classification and the relevant disposal of resources for dealing with the household solid waste in Pingjiang and Ningxiang county.Home or village cycling mode for organic waste,the town cycling mode for construction waste,and county cycling mode for recycling waste were put forward on the basis of different waste and its output and property.The economic benefit of the mode of resources utilization,its feasibility in technique,market and economy were analysed in this paper.更多还原
