Abstract

Abstract

Point source pollution, such as rivers (seas) sewage outfalls, is closely related to the environmental quality of surface water. It is also the main cause of ecological environment pollution. Scientific and effective monitoring, evaluation and remediation of water environment pollution, systematically mastering the data of the rivers (seas) outfalls, and combining it into the water ecological environment intelligent monitoring and supervision system database is essential. In this paper, for the objective problem that submerged outfalls are difficult to investigate and review, a set of multi-source data fusion technology systems for secondary investigation of submerged outfalls was established based on acoustic, optical and other detection means. Taking a survey in a Town in Shanghai as an example, 51 suspected submerged outfalls were identified and located within a total of 35.5 km of shoreline survey area by multi-method collaboration. Among them, 49 locations were reviewed and confirmed to be present, with a success rate of 96.1%. After the review, 18 new submerged outfalls were found, and 31 registered submerged outfalls were also identified, i.e. the success rate of the known underwater outfalls reached 100%, which further verified the reliability of the secondary survey technology system. This also provides detailed basic data for the transparent regulation of emissions, scientific and precise pollution control and ecological environmental protection.
