摘要
统计分析了全国15个省(市、区)33个高速公路服务区污水中的pH值,SS,COD,BOD5,NH3-N,磷酸盐,石油类和动植物油等8个水质因子,发现除pH值呈正态分布外,其余因子均符合对数正态分布。pH均值为7.47,而SS,COD,BOD5,NH3-N,磷酸盐,石油类和动植物油等质量浓度均值分别为126.95,357.33,158.54,26.87,4.85,4.82,5.97mg/L。集对分析表明我国高速公路服务区污水除含有SS,石油类等特征污染因子外,与典型的低浓度生活污水水质较为相似,宜优先采用沉淀、隔油等措施降低SS,石油类负荷,然后采用低浓度型生活污水处理工艺。
Eight water quality indicators,including pH,SS,COD,BOD5,NH3-N,phosphate salt,oil,animal and vegetable oil of 33 major highway service areas in 15 provinces （ cities or districts） in China were inspected and analyzed.The results indicated that the pH shows the normal distribution,while the others have log-normal distributions.The average pH is 7.47,and the average concentrations of SS,COD,BOD5,NH3-N,phosphate salt,oil,animal and vegetable oil are 126.95,357.33,158.54,26.87,4.85,4.82,5.97mg/L,respectively.The results of the set pair analysis showed that the water quality of highway service areas is similar to that of the typical,low concentration life sewage,excepting that the sewage in highway service areas contained some characteristic pollutants,such as SS,oil,etc.Thus,the prior treatment method is reducing the concentration of SS and oil by precipitation and separating oil in advance,and then treating the sewage with the techniques for the low concentration life sewage.
