摘要
通过对位于大连一霍尔果斯高速公路西安至潼关段95km处的良田服务区排放污水的水质和水量进行24h的连续监测分析，得到了监测当日排放污水水量的时变化系数和水质参数值。通过对比分析入区车流量和水质水量监测数据，得出以下结论：（1）该服务区排放污水的CODCr浓度范围517—1116mg／L，平均值为758mg／L，标准偏差为159；氨氮浓度范围为28-151mg／L，平均值为82m∥L，标准偏差为32。表明高速公路服务区污水属高COD高氨氮的生活污水。（2）监测当日，该服务区排放污水量47．9m3／d，排放污水的时变化系数为1．7。因而高速公路服务区污水量时变化系数不宜按照一般小流量生活污水的时变化系数取值。（3）服务区排放污水的水质水量特征与进入服务区的人员和车辆数量有关。入区车流量随时间的变化分布较为均匀，削弱了总污水量的小时变化强度。
The hourly variation coefficient of wastewater quantity and the parameters of wastewater quality of the monitoring day were obtained via 24-hour monitoring and analyzing the quality and quantity of wastewater discharged from the Liangtian service area which is located in the 95 km of the Xi＇an-Tongguan section of the Dalian-Huoerguosi expressway. Based on the comparison and analysis of traffic volumes entering the service area per hour and the data of wastewater quantity and quality obtained, following conclusions are drawn： （ 1 ）. The range of CODc, and ammonia concentration of the wastewater discharged from the service area is 517~1 116 mg/L and 28~151 mg/L respectively. Mean value of the concentrations of CODcr and ammonia is 758 mg/L and 82 mg/L respectively. The wastewater discharged from the service area is domestic sewage with high concentrations of COD and ammonia. Standard deviation of the concentrations of COD and ammonia is 159 and 32 respectively. （2）. In the monitoring day, the sewage flow discharged from the Liangtian service area is 47.9 m3/d,the hourly variation coefficient of wastewater discharged from the service area is 1.7. It is proposed that the hourly variation coefficient should not be taken according to the general small-flow domestic sewage. （3）. The characteristics of wastewater quality and quantity are related to the number of people and vehicles entering the service area. The less variation of vehicle volume entering the service area per hour weakens the intensity of hourly variation of the total wastewater quantity
