Abstract: The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on “control for bottom, regulation for middle and governance for top”, including: “control for bottom”—controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; “regulation for middle”—regulating primary productivity in a water body to inhibit the recovery of the algae; and “governance for top”—reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.

Abstract: Embodiments of the present application relate to methods, devices, apparatuses, and storage media for monitoring and analyzing air pollution. The methods includes acquiring air quality data of a monitored area, where the air quality data includes ground air quality data corresponding to the monitored area and N-component data collected by an air sensor in the monitored area; inputting the air quality data into a pollution analysis model, where the pollution analysis model is previously trained according to the ground air quality data and the N-component data; and determining whether the air quality data of the monitored area is abnormal according to an output result of the pollution analysis model. The methods may solve the technical problem of inaccurate monitoring results caused by the susceptibility of air quality monitoring in related technologies to human intervention.

Abstract: The disclosure relates to the technical field of aquaculture, and more particularly to a fish breeding device provided with a magnetizer and a method for accelerating normal propagation and growth speeds of fishes. The fish breeding device includes a box body, a controllable partition plate, an extraction pump, and the magnetizer; the controllable partition plate is arranged in the box body and used for dividing the inner space of the box body into a feeding area and a non-feeding area; the extraction pump is arranged on the controllable partition plate and used for exchanging the water body in the feeding area with the water body in the non-feeding area; the magnetizer is arranged on the outer wall of the box body corresponding to the feeding area, and used for magnetizing the water body of the feeding area. In the disclosure, fish eggs are further hatched by the magnetized water.
