摘　　要：为研究准好氧填埋技术在海拔高、空气稀薄、气温低、昼夜温差大、蒸发强、降雨少的青藏高原地区的适用性,在青藏高原不冻泉地区开展了为期14个月的准好氧填埋单元试验研究。试验结果表明,准好氧填埋单元的渗滤液COD浓度由3307 mg/L降低到403 mg/L,氨氮由135.4 mg/L降低到0.04 mg/L,渗滤液量大幅减少。研究为青藏高原地区提供了一种垃圾处理方式。In order to study the applicability of semi-aerobic landfill on the Qinghai-Tibet plateau, which is high altitude, rareness of air, low temperature, great difference in temperature between day and night, strong evaporation, little rainfall, the pilot-scale of semi-aerobic landfill experiment was carried out at the Budongquan for 14 months, the results show that the concentration of COD dropped from 3307 mg/L originally to 403 mg/L finally; the concentration of ammonia nitrogen dropped from 135.4 mg/L to 0.04 mg/L during the corresponding time, moreover, the quantity of leachate decreased greatly. The research provided a municipal solid waste disposal method for the Qinghai-Tibet plateau.
