- Abstract:
- Taking the mountainous and hilly city in the Yellow River basin as an example, in view of the current situation of insufficient collection efficiency of sewage systems, a monitoring and evaluation system based on the water quantity accounting method and the water quality parameter comparison method is constructed to quantitatively analyze the intrusion risk of external water. The monitoring evaluation results show that the BOD5 concentrations of the source domestic sewage in the study area range from 350.0 to 750.0 mg/L, which are generally high. The rainfall infiltrated into the sewage system is less than 4% of the sewage in the dry season. The intrusion rate of external water such as river water and ground water in the sewage system laid along the river exceeds 60%. Based on the analysis results, the main means including technical countermeasures such as pipeline modification, pipeline reconstruction and the main pipe system improved, are put forward for the mountainous and hilly cities in the northern arid region, which can provide references for the quality and efficiency improvement of other urban sewage systems.
