摘　　要：对北京市密闭式清洁站垃圾渗沥液进行了取样分析。结果表明:渗沥液为高浓度有机污水,COD为20 000～60 000 mg/L,BOD5为6 000～20 000 mg/L,氨氮为300～500 mg/L。渗沥液所含颗粒物介于胶体和超胶体范围。三维荧光光谱(3D-EEM)和红外光谱(FTIR)显示渗沥液污染物多为蛋白质、多糖等物质。The waste leachate from waste collection stations in Beijing was analyzed. The results showed that waste leachate is organic sewage with COD concentration of 20 000-60 000 mg/L, BOD5 concentration of 6 000-20 000 mg/L and ammonia nitrogen of 300-500 mg/L, respectively. Particulate matter in waste leaehate was distributed between colloid and ultra- colloid. The 3D-EEM spectra and FFIR spectra indicated that most of pollutants in waste leachate were proteins and polysaecharides.
