Through the field investigation of 198 sewage outlets in Jiangyang section of Luzhou,the Yangtze River,88 sewage outlets met the sampling conditions,and the analysis results showed that 86 sewage outlets exceed the standard.It was found that the sewage of some old communities did not completely enter the pipe network.The sewage discharge in rural areas was scattered and the wastewater was discharged directly.Some small and medium-sized enterprises and small production workshops had disorderly,direct and excessive wastewater discharge.Problems such as unstable operation of sewage treatment facilities and mixed flow of rain and sewage were prominent.Combined with the law of the people’s Republic of China on the protection of the Yangtze River and the current situation of sewage outlets into the river in this area,suggestions were put forward for the control of pollution sources and the regulation of sewage outlets into the river.
