摘要
目的了解乌鲁木齐市天津南路片区生活垃圾构成和物理性质。方法于2007年以每周1-2次的采样频率,在无大风（3级以上）、雨、雪的条件下采集标本,并按照国家标准对天津路垃圾转运站生活垃圾的物理成分、容重、含水率、可燃物含量等进行检测。结果乌鲁木齐市天津南路片区混合垃圾中有机垃圾（草木和橱余）、无机垃圾（灰渣和砖瓦）以及可回收垃圾（金属、玻璃、塑料、纸类、织物）所占比例分别是57.0%,17.0%和26.0%。该片区混合垃圾不同季度平均容重为350.09 kg/m3,平均含水率38.27%,可燃物占垃圾总量的43.02%。各季节3个指标间的差异均有统计学意义（F容重=4.026,P=0.051;F含水率=9.901,P=0.005;F可燃物=26.658,P=0.000）;垃圾容重3,4,5月份达到最高值,垃圾中可燃物含量在1,2月份达到最高值。结论乌鲁木齐市生活垃圾理化性质存在季节差异,应根据生活垃圾的特点,提出相应的合理化建议,为建立城市生活垃圾的科学收运体系和卫生处理设施提供依据。
Objective To know constitution of refuses and analyze its physical property in area of Tianjing South Road in Urumqi.Methods The refuse samples were collected 1-2 times one week when the weather was fine.According to the national law,the physical property such as constitution,volume-weight,water content and combustible content was detected.Results The proportions of organic,inorganic and retrieved garbage were 57.0%,17.0% and 26.0%.The average volume-weight of the refuses was 350.09 kg/m3 with the average proportion and water content of 38.27%,and the combustible content was 43.02%.There were statistical significances in the three indices in different seasons（Fv-w=4.026,P=0.051;Fmoisture content=9.901,P=0.005;Fcombustible content=26.658,P=0.000）.The volume-weight reached the maximum in March,April and May,while the combustible content was at peak in January and February.Conclusions There is seasonal difference in physical and chemical property of the refuses in Urumqi.Proper suggestion should be proposed according to characteristics of the refuses,so as to provide basis for establishing process facility of the refuses in the city.
