The application discloses a solar landscape ultrasonic atomization light-shielding and algae-inhibiting floating island, which comprises a floating island body, a plurality of circumferential array arranged ultrasonic atomization nozzles, solar panels and winding mechanisms are installed on the outer side of the floating island body, and integrated control modules and propellers are respectively installed on the upper and lower sides of the floating island body; the ultrasonic atomization nozzles, the solar panels, the propellers and the winding mechanisms are electrically connected with the integrated control modules. The application utilizes solar energy to continuously provide power for the ultrasonic atomization nozzles, carries out ultrasonic atomization, and the atomized water droplets shield light, so that the underwater light intensity decreases and the photosynthesis intensity of algae is weakened, thereby achieving the purpose of inhibiting the growth of algae, and the application also has a certain landscape effect. When the counterweight balancing block is controlled by the winding mechanism and is wound by water grass, the rising pressure will push the folding piece to pop out the cross-shaped cutter, the cross-shaped cutter is cut off near the water grass in an instant, and the counterweight balancing block is conveniently recycled above the water surface.

This invention discloses a method for predicting the three-dimensional spatiotemporal distribution of algae in aquatic bodies based on a physical information neural network (PINN), belonging to the field of algal bloom prediction and control technology. Addressing the problems of poor generalization of purely data-driven models, difficulty in fitting purely mechanistic models, and insufficient vertical fitting ability in existing algal distribution prediction methods, this invention integrates the advantages of physical mechanisms and data-driven algorithms. It embeds the advection-diffusion-response (ADR) equation of algal growth into the loss function of a physical information neural network (PINN), constructing a hybrid prediction model that combines data fitting accuracy with physical constraints. This achieves accurate prediction of the three-dimensional spatiotemporal distribution of algae and inversely obtains physically meaningful ecological parameters. This invention improves the accuracy, generalization, and physical interpretability of algal distribution prediction and can be effectively applied to the monitoring, early warning, and aquatic ecological environment management of harmful algal blooms.

This invention discloses an algae-bacterial symbiosis device and its application in purifying air in enclosed spaces. The algae-bacterial symbiosis device provided by this invention can not only purify odorous gases containing VOCs using microorganisms, but also fix CO2, the metabolic end product of odorous gases, through algal photosynthesis, while simultaneously treating CO2 generated by human activities. It purifies the air and provides sufficient oxygen, serving as a source of indoor air. The algae-bacterial symbiosis device operates at normal temperature and pressure, requiring only electrical energy input and no additional energy consumption (such as fuel), resulting in significant economic benefits and low-carbon characteristics. Furthermore, the device does not produce secondary pollution; the purified indoor air can be reused indoors, and the nutrient solution required for algae growth and metabolism can be recycled without external discharge. This algae-bacterial symbiosis device enables air circulation within enclosed spaces and features small size and high purification efficiency.

This invention belongs to the field of ecological restoration technology and discloses a shellfish-algae reef for estuarine ecological restoration and fish resource conservation. The reef is composed of layered composite structural units, vertically arranged as follows: a bottom shellfish attachment zone, a middle algae growth zone, and an upper fish habitat zone. The shellfish attachment zone has a porous microtexture of 50–200 μm; the algae growth zone contains an anchoring mesh and nutrient slow-release units; and the fish habitat zone has a tubular shelter structure and an spawning substrate. The units are made of biodegradable composite materials, and their surfaces are functionalized to form a bio-attachment induction interface. Multiple units are arranged alternately or intermittently to form a flow velocity gradient region. This invention can synergistically construct multi-trophic-level biological communities, improve habitat complexity and ecosystem stability, and is suitable for estuarines affected by diversion water and with low natural transparency, significantly enhancing the effects of estuarine ecological restoration and fish resource conservation.
