摘　　要：调查了重庆地区高速公路服务区污水排放的主要特征,发现重庆高速公路服务区污水的排放量为4.38～131.50 m3/d,平均排放量为56.25 m3/d,污水水质在整体上与典型的低浓度型生活污水类似。污水处理率为27.43%～71.39%,平均处理率为51.76%,日和季节的水质变化的各项指标的最大值与最小值间差距分别在11%～33%和36%～210%之间。评述了国内外服务区污水处理现有工艺,将其划分为好氧处理、厌氧处理、好氧-厌氧处理和生态处理等4个大类,在重庆地区高速公路服务区污水排放特征的基础上,推荐了"分类预处理-生态土壤渗滤处理"为重庆地区高速公路服务区污水的适合工艺。Main characteristics of sewage from highway service area （HSA） in Chongqing were studied. Results showed that sewage discharge capacity was 4.38-131.50 m3/d, with average 56.25 m3/d. Water quality of HAS sewage was similar to typical low concentration sewage and removal efficiency was 27.43%-71.39%, with average 51.76%. Gap between maximum and minimum values of day and seasons water quality index were 11%-33% and 36%-210%. The treatment technologies were discussed in details, and were classified as aerobic treatment, anaerobic treatment, aerobic-anaerobic treatment and ecological treatment. Based on analysis of sewage characteristics, the pretreatment-ecological soil filtering was suggested as sewage treatment method in HAS of Chongqing.
