The invention discloses a pollutant tracing method and device, a computer device and a storage medium, and relates to the technical field of environmental protection. The pollutant tracing method comprises the following steps: carrying out online water quality monitoring on a plurality of target point locations in a supervision area, determining a certain target point location as a pollution monitoring point location when monitoring that the water quality of the certain target point location is abnormal, and acquiring water quality characteristics of the pollution monitoring point location andcharacteristic pollutants of the pollution monitoring point location; determining a target pollution industry according to the water quality characteristics and the characteristic pollutants; and determining a pollution source object from a pollution tracing range corresponding to the pollution monitoring point location according to the target pollution industry, wherein the pollution source object is a main body of the water pollution event causing the pollution monitoring point location. According to the embodiment of the invention, the pollution source object can be quickly determined, andthe pollutant tracing efficiency is improved.

The invention provides a museum business data storage and query method and system based on a blockchain, and the storage method comprises the steps: carrying out the under-chain storage of total data containing museum business data and data numbers through employing a distributed relational database, and constructing a blockchain network; hashing the total data to obtain a first hash value, and storing the first hash value and the data number in a blockchain network. According to the query method, while full data corresponding to museum business data is queried and retrieved through a distributed relational database, a corresponding first hash value is queried on a blockchain network, and the full data corresponding to the museum business data is hashed and then compared with the first hash value to verify data integrity and consistency, so that whether the data is legal is confirmed to prevent the data from being tampered.

The invention provides a pollution source association information determination method and device, and terminal equipment. The method comprises the steps of determining a to-be-associated target monitoring site and a target pollution source; calculating a monitoring angle of the target monitoring station relative to the target pollution source based on the station coordinate of the target monitoring station and the position information of the target pollution source; dividing a plurality of angle intervals according to a preset wind direction group; determining association information between the target monitoring station and the target pollution source based on the angle interval where the monitoring angle is located, wherein the associated information comprises an associated distance and/or an associated orientation. According to the invention, the correlation information between the pollution source and the monitoring station can be reliably determined, so that the tracing efficiency of the pollution source is remarkably improved.

The invention discloses a hierarchical coding and tracing method for image operation information. The method comprises the following steps: (1) obtaining the operation information; (2) encoding operation information; (3) updating the operation information; and (4) tracing the operation information. According to the invention, the image data operation information with a hierarchical structure is obtained, and the unified expression and coding of the image data operation information are realized by utilizing the outer product operation of geometric algebra and a multi-vector structure; based onthe code updating of the operation information node and the operation link, the intersection operator and the dimension operator are used to complete the operation of operation information tracing andthe like, the memory occupation of the tracing information is reduced, and the tracing efficiency is improved.

The invention provides a water pollution traceability method based on ultraviolet-visible spectrum data. The method comprises the following steps: S1, establishing a normalized water pollution traceability spectrum library; S2, obtaining a three-dimensional ultraviolet-visible-to-be-traced water quality fingerprint spectrum of a to-be-traced water pollutant; and S3, tracing the to-be-traced water pollutants intelligently. The principle is as follows: obtaining known water samples of known pollution sources of rivers, lakes and multiple industries (processing plants), and obtaining ultraviolet-visible-water pollution water quality fingerprint spectrum data under different dilution concentrations through detection and pretreatment; carrying out nonlinear fitting to obtain a three-dimensional ultraviolet-visible-water pollution water quality fingerprint spectrum of each known water sample; carrying out normalization processing on the obtained three-dimensional ultraviolet-visible-water pollution water quality fingerprint spectrum to form a normalized water pollution traceability spectrum library; and comparing the spectral features of the to-be-traced water pollutants with the spectral features of the known water sample in a traceability simulation mode, and obtaining a potential pollution list, and therefore, the method has the advantages of being high in traceability efficiency, high in timeliness and high in accuracy.
