摘　　要：对南京市某高校校园生活垃圾物理组成、含水率、热值及生活污水中污染物浓度进行测试和分析。结果表明:校园生活垃圾平均密度为134.28 kg/m^3,主要物理组分为易腐类(23.28%)、塑料(17.50%)、砖石(16.83%)、纸(14.26%)和草叶木(12.41%);总含水率为39.59%,热值为8 384 kJ/kg。与城市混合垃圾相比,校园生活垃圾可燃组分含量多,热值高,焚烧处置可减量95%。校园生活污水中氮磷浓度较低,食堂污水中SS、COD分别为51~71 mg/L和1 004.2~1 297.6 mg/L,洗衣污水中COD为287.1~340.4 mg/L,超过城镇污水处理厂污染物排放标准限制;洗澡污水满足绿地灌溉水质要求且产量集中,可用于校园绿化。Physical composition,moisture content,calorific value and concentration of domestic sewage pollutants in one campus in N anjing were tested and analyzed. The results indicated that the density,moisture content and calorific value of campus domestic waste was 134.28 kg/m^3,39.59% and 8 384 kJ/kg,respectively. And the main components of physical composition were perishable material（23.28%）,plastic（17.5%）,brick（16.83%）,paper（14.26%）,wood-grass-leaves（12.41%）and so on. Compared with municipal mixed waste,campus domestic waste contained more combustible component and possessed higher calorific value,which could be reduced 95% by incineration. The concentration of nitrogen and phosphorus in campus domestic sewage were low,SS and COD of canteen sewage were 51~71 mg/L and 1 004.2~1 297.6 mg/L and COD of washing wastewater was 287.1~340.4 mg/L,which exceeded the standards for pollutant discharge in urban sewage treatment plants. The production of bathing wastewater was concentrated and met the water quality requirement of greenbelt irrigation,which could be used for campus greening.
