Embodiment 1
[0020] The embodiment of the present invention provides a sewage traceability method based on comprehensive two-dimensional gas chromatography mass spectrometry, such as figure 1 As shown, the method includes the following steps:
[0021] S1: Determine all enterprises that can discharge sewage to the polluted water area according to the polluted water area to be analyzed.
[0022] The specific determination method in this embodiment is as follows: the determination is carried out in combination with the geographic location of each enterprise, enterprise distribution, enterprise type, enterprise EIA data, water supply and drainage pipe network conditions, groundwater monitoring wells and groundwater quality status.
[0023] like figure 2 As shown, the polluted water area to be analyzed in this embodiment is a pool of well water in an industrial zone. By investigating the enterprises in the industrial park, it is determined that the possible sources of sewage in the pool well ...

The invention relates to a sewage tracing method based on comprehensive two-dimensional gas chromatography-mass spectrometry. The method comprises the following steps: S1, determining all enterprises capable of discharging sewage to a polluted water area according to the polluted water area to be analyzed; s2, detecting sewage discharged by each enterprise and sewage in the polluted water area through a comprehensive two-dimensional gas chromatography-mass spectrometry detection instrument, and extracting characteristic factors contained in the sewage; and S3, performing comparative analysis on the characteristic factors contained in the sewage of the polluted water area and the characteristic factors contained in the sewage discharged by each enterprise to obtain the contribution ratio of the sewage discharged by each enterprise to the sewage of the polluted water area, and determining the source of the sewage in the polluted water area according to the contribution ratio. The method has the advantages of simplicity and convenience in operation, accuracy in traceability, high analysis efficiency and wide application range.
Description
technical field [0001] The invention relates to the field of sewage traceability, in particular to a sewage traceability method based on comprehensive two-dimensional gas chromatography mass spectrometry. Background technique [0002] In daily production activities, industrial enterprises are affected by equipment failure, operational errors, man-made damage, etc., so that industrial sewage enters natural rivers or underground pipelines without treatment, resulting in sudden water pollution incidents, which can cause huge economic and property damage. Losses, and it takes huge human and financial resources to repair the damage to the water ecological environment. In addition, water pollution affects the safety of water supply, poses a serious threat to people's health and safety, and affects the normal living order of residents in the pollution-affected areas. With the increasingly strict environmental supervision requirements, it is very important to investigate the pollut...
