Abstract
This thesis, based on questionnaire survey, field investigation, sewage sample test etc., studies the relationship between water consumption and discharging volume, type and process of sewage treatment facilities, and statistical analysis of sewage discharge whereabouts in highway service areas. There are 35.5% and 27.6% respectively in the service areas of north and south China without sewage treatment facilities installed or operated. The great difference between the highway service areas of north and south China lies on the differences in geographical location, climate and level of economic development. The problem of nearby discharging of sewage and sludge in the service areas, lower recycle rate, unused or damaged sewage treatment equipment seems to be prevalent. On the whole, quite a few sewage treatment facilities and processes in service areas are not capable of managing the sewage in service areas, which has great potential for improvement.
