Description

Technical Field

[0001] The utility model relates to the technical field of algae attachment culture, in particular to an algae attachment bed for marine ecological restoration. Background Art

[0002] Algae are a type of eukaryotic organisms in the protist kingdom. They are mainly aquatic and have no vascular bundles. 90% of photosynthesis on Earth is carried out by algae. Algae itself has the function of purifying the environment, but when the concentration of organic matter in the water is too high, algae cells can grow heterotrophically and directly absorb nitrogen and phosphorus organic pollutants such as urea, amino acids, and phosphates, as well as difficult-to-degrade and toxic substances such as lignin and phenols, and can even absorb heavy metals. In view of this characteristic of algae, using algae to repair marine water bodies in offshore areas has become an effective technical means.

[0003] An algae attachment bed is a device that can cultivate algae in the ocean and provide basic conditions for the rapid reproduction and stable growth of algae. For example, the "Algae Attachment Bed for Marine Ecological Restoration" (hereinafter referred to as D1) disclosed in Chinese patent literature has a publication number of CN216764463U and an authorization announcement date of June 17, 2022. D1 includes a floating plate with a light-transmitting hole, a mounting frame is provided on the top of the floating plate, and a cage body is provided at the bottom of the floating plate. A plurality of algae attachment beds are installed in the cage body, and a fixed mesh is provided on the algae attachment bed, and an algae attachment substrate is provided on the fixed mesh. An aeration branch pipe is provided at the inner bottom of the cage body, and an aeration main pipe is connected to the aeration branch pipe, and an air pump is connected to the aeration main pipe. The aeration branch pipe is provided with air outlets, and a spoiler is rotatably connected to the aeration main pipe. The spoiler is provided with spoiler holes, and spoiler plates are provided in the spoiler holes. Fan blades are provided on the edge of the spoiler, and a water pump is provided on the mounting frame. A power pipe with a water outlet tangential to the fan blades is provided on the water pump. However, the attachment bed set in D1 is a layered setting, and the water body absorbs light strongly. Under this setting, the light that can be absorbed by the attachment bed at the bottom will be very weak, which is not conducive to the growth of algae attached thereon. Utility Model Content
