This utility model discloses an ecological restoration device for urban water bodies, comprising: several concave filter boxes, a J-shaped siphon suction pipe, and a filtration restoration structure. The concave filter boxes are mutually capped, and the J-shaped siphon suction pipe is connected to the highest concave filter box. The filtration restoration structure is installed inside the concave filter boxes. This utility model relates to the field of water body ecological technology. By using multiple concave filter boxes mutually capped, in conjunction with the J-shaped siphon suction pipe and the filtration restoration structure, efficient water purification is achieved. The device utilizes photovoltaic panels to convert solar energy into electrical energy, driving an ozone emitter and an air pump to introduce ozone and high-pressure gas into the concave filter boxes. The ozone is then diverted through a bubble emission net, enhancing the oxidation and purification effect of the water.

This invention discloses a real-time assessment method for forest ecological carbon sinks based on the fusion of multiple meteorological parameters, relating to the field of forest ecological technology. The specific steps of this method are: data acquisition, data preprocessing, data screening, data fusion, and data accounting. This invention uses a time-series analysis unit combined with the time-series pattern of forest carbon sink accumulation to divide carbon sink sensitive periods and non-sensitive periods. Based on the correlation between meteorological data and carbon sink changes, it completes the screening of key data and eliminates redundant data. This scheme takes the time-series change mechanism of forest carbon sinks itself as the core basis, abandons the logic of indiscriminate data processing, accurately locks meteorological data that are highly correlated with carbon sink changes, and aligns with the inherent characteristics of carbon sink formation and fluctuations from the data screening stage, eliminating the interference of redundant data on the assessment process, and providing data source support that is highly matched with carbon sink changes for carbon sink accounting.

This application provides a method for early warning of polycyclic aromatic hydrocarbons (PAHs) in coking coal basins, relating to the field of environmental ecology technology. The invention includes the following steps: selecting first to third-level sub-basins along the main stream based on the topography of the coking coal basin, collecting water samples and surface sediments; determining the concentration and composition of PAHs, and qualitatively analyzing the pollution sources of PAHs through the ratio distribution between PAH isomers; selecting representative water and sediment samples for metagenomic sequencing to obtain information on the structure and functional genome composition of microbial communities; conducting ecological risk assessment of PAHs using the risk entropy method; and providing early warning of the ecological risk of PAHs in the coking coal basin. This invention organically couples the spatiotemporal distribution of PAHs, the ecological risk assessed by chemical methods, and the structural and functional responses of microbial communities to construct a spatial pollution identification system encompassing surface water, sediment, and land use information, which helps improve the ability to analyze coal-coke composite pollution.
