摘　　要：污水干管是城市生活污水的重要运输和转移通道,但由于其一般处于高水位运行,难以开展内窥检测,如何诊断干管淤积、破损、渗漏等缺陷问题一直是城市水环境综合治理中的重要难题。以重庆市沙坪坝区Q流域为例,通过水质水量监测和管网数据分析等手段,对沿河污水干管开展预诊断和溢流风险识别研究。结果表明,水量水质监测可以有效识别干管中的不平衡点,发现潜在的外水入渗、污水渗漏和井口溢流等风险。其研究成果为后续干管修复提供了理论基础和技术支撑。Being important transportation and transfer channel of urban domestic sewage,Main sewers are hard to be detected by endoscopy because they always operate at high water levels.How to diagnose the defects such as silta tion,damage and leakage of main pipes has been an important problem in comprehensive treatment of urban water environment.Takes Q basin in Chongqing as an example,the main sewers are prognosed and overflow risk identificated of by means of water quality and quantity monitoring.The results showed that water quantity and quality moni toring can effectively identify the disequilibrium point in the main pipe,and find potential risks such as external water infiltration,sewage leakage and wellhead overflow.The research can provide theoretical basis and technical sup-port for the subsequent main pipes repair.
