摘要
随着我国经济的快速发展,城镇化进程不断加快,大量城市固体废物(MSW)产生。MSW具有较强的毒性、致突变活性和致癌性,其不断增加严重威胁人体健康和生态环境。因此,必须制定严格的法规控制MSW污染,利用科学方法对MSW进行分类和回收。目前,我国的MSW可分为四大类,即餐厨垃圾、可回收垃圾、有害垃圾和其他垃圾,其中,餐厨垃圾最为常见,大多采用堆肥法进行处理。本文论述了我国MSW的物理特性和组成,并利用SPSS软件分析二者的关系,以推进MSW的分类、运输、储存和资源化利用,建立无废城市,实现绿色发展。结果表明,堆积密度与灰尘和砖块的比例呈高度正相关,与食物、金属、玻璃、塑料和橡胶的比例呈高度负相关;湿基低位热值与塑料和橡胶的比例呈高度正相关;含水量与食物的比例呈高度正相关。
With the rapid development of China’s economy and the accelerating process of urbanization, a large number of municipal solid wastes(MSW) are produced. MSW has strong toxicity, mutagenic activity and carcinogenicity, and its increasing is a serious threat to human health and the ecological environment. Therefore, strict regulations must be formulated to control MSW pollution, and scientific methods must be used to classify and recycle MSW. At present, MSW in China can be divided into four categories, namely food waste, recyclable waste, hazardous waste and other waste, among them, food waste is the most common, and most of them are treated by composting. This paper discusses the physical characteristics and composition of MSW in China, and uses SPSS software to analyze the relationship between the two, so as to promote the classification, transportation, storage and resource utilization of MSW, establish a zero-waste city, and achieve green development. The results show that the bulk density is highly positively correlated with the proportion of dust and bricks, and highly negatively correlated with the proportion of food, metal, glass, plastic and rubber;low calorific value on wet basis is highly positively correlated with the proportion of plastic and rubber;water content is highly positively correlated with the proportion of food.
