【摘要】 在湖北省三峡库区,选择了24个典型农户作为研究对象,分别对农户每个季节连续3d的生活垃圾产生量、理化性质、垃圾中TN、TP产生系数进行了检测与分析。结果表明,湖北省三峡库区农村生活垃圾人均日产生量0.743kg/(d·人),生活垃圾产生量受地域、季节及农户经济收入水平的影响。生活垃圾组成中,有机垃圾(主要是厨余垃圾)约占40%,其他垃圾(灰土、煤渣等)占41%,可回收垃圾(废纸、废塑料等)约占18%,有害垃圾占1%。农村生活垃圾含水率约41%,容重0.368t/m3,有机垃圾日产生量0.212kg/(d·人),其中TN含量为14.66g/kg、TP含量为2.42g/kg。TN平均产污系数为0.993g/(d·人),TP平均产污系数为0.153g/(d·人)。依以上参数估算,湖北省三峡库区120万农村常住人口,垃圾年产生量为32万t、87万m3,垃圾中每年TN、TP产生量为435t、67t。更多还原

【Abstract】 24 typical rural households,from 4 counties of Three Gorges Reservoir area of Hubei province were selected to study the rural solid waste(RSW) production rates,the features,and the parameters of characteristic pollution which were produced in continuous 3 days of each season.The result showed that the production rate of RSW averaged 0.743 kg/d per capita;which was effected by the location,season and income of the farmer.RSW in this area was mainly composed of organic waste(food waste),recyclable waste(paper,plastic package),harmful waste and other waste(brick debris,cinder),accounting for 40%,18%,1% and 41% of the total RSW by weight,respectively.The water content of RSW was 41%,and the volume weight was 0.368 t/m3 averagely.The production rate of the organic waste averaged 0.212 kg/d per capita,in which the content of TN and TP were 14.66g/kg and 2.42g/kg.In this region,the producing coefficient of TN,TP were 0.993(N)g/d per capita,0.153(P)g/d per capita averagely.Based on the foregoing parameters,it can be estimated that the total annual production rate of RSW in the Three Gorges Reservoir area of Hubei province was 320 000 t,about 870 000 m3,and the annual amount of TN,TP from RSW were 435 t and 67 t,respectively.更多还原
