Method and system for tracing underground water pollution caused by sulfonamide antibiotics

Abstract

The invention belongs to the technical field of environmental protection traceability, and particularly relates to a traceability method and system for underground water pollution caused by sulfonamide antibiotics, and the method comprises the following steps: collecting information of a traceability area, collecting an underground water sample, pre-treating the collected water sample, extracting sulfonamide antibiotics in the pre-treated water sample, and measuring and analyzing the content of the sulfonamide antibiotics, obtaining analysis data; analyzing and predicting the analysis data, determining that the water sample is abnormal if the analysis data is detected to be greater than a preset threshold value, or else, determining that the content of the sulfonamide antibiotics in the underground water sample of the traceability area meets the water quality standard; acquiring information of a traceability area corresponding to the abnormal signal of the water sample, and starting emergency response and then running emergency monitoring; and obtaining pollution source information by calculating an estimated value or probability distribution of a pollution emission parameter in the water sample of the traceability area, and repeating the steps until the traceability search range is narrowed until the pollution source can be found through field investigation. According to the method, the sulfonamide antibiotics in the underground water can be quickly traced.

Description

Technical field [0001] The present invention belongs to the field of environmental protection traceability technology, specifically relates to a sulfa antibiotic groundwater pollution traceability method and system. Background [0002] Sulfonamides are the most widely used and largest class of broad-spectrum bacteriostatic drugs, which are widely used in the pharmaceutical industry, aquaculture and animal husbandry for the prevention and treatment of bacterial infections and fungal diseases. Although antibiotics exist in trace form in the water environment, they are in a "long-lasting" state due to their refractory degradation and continuous input, and are extremely easy to remain in groundwater, which has become a new type of groundwater pollution. [0003] Sulfonamide antibiotics in the environment are mainly derived from human and animal drugs, antibiotics entering the water environment are mainly from compounds that have not been fully metabolized in animals, most antibiotics...

AI Technical Summary

Problems solved by technology

Most sulfonamide antibiotics are water-soluble and have a low Henry constant, so they are easy to diffuse in the environment, and because of their migration and transformation in groundwater, it is difficult to quickly eliminate their impact on the environment in the natural environment , so it has become a difficult point to control the pollution of sulfonamide antibiotics

[0005] In the past, people traced the source of groundwater pollution mainly by sampling the polluted downstream water samples and the water samples from the sewage outlets of upstream pollution-related enterprises after the accident, and comparing the detection and analysis of the water samples with the detection results to realize the pollution source. Trace the source and find the party responsible for the pollution, but there may be a problem that due to the large number of pollution-related enterprises in the upstream, it is impossible to accurately find the pollution source at the first time, which will easily cause delays in the treatment of groundwater pollution
