Description

Technical Field

[0001] The invention relates to the technical field of marine environmental protection, and in particular to a heavy metal treatment device for a seaweed protection area for marine environmental protection. Background Art

[0002] At present, coastal countries and island countries attach great importance to the impact of heavy metals on the marine environment. The so-called heavy metals refer to metals with a density greater than 5g / cm3. Due to the rapid development of industrial and agricultural production, especially the rapid development of light and heavy industries in coastal areas, heavy metal pollution in the marine environment has become increasingly serious worldwide. Since most heavy metal elements are input through rivers, which constitute the main way to enter the sea, the pollution of heavy metals in estuary waters is relatively serious. Seaweed is a monocotyledonous higher plant living in shallow waters in tropical and temperate seas. It is the only angiosperm submerged in shallow seawater and is widely distributed. In coastal waters, seagrass plays a very important role in the marine ecosystem. It can not only absorb nutrients, improve water quality, provide habitats, breeding grounds and food sources for many animals, but also fix the bottom, resist wind and waves, and protect the coast. In addition, seagrass beds have a huge carbon storage capacity. Heavy metal pollution also has an important impact on seagrass. Heavy metals reduce photosynthetic efficiency by destroying the ultrastructure of chloroplast membranes and endoplasmic membranes, reducing chloroplast synthesis, blocking electron transfer of electron transporters, and destroying key enzymes of the Calvin cycle and closing stomata, thereby limiting the fixation efficiency of CO2. Therefore, when protecting seagrass, it is necessary to prevent seagrass from being affected by heavy metals; Current heavy metal treatment generally places an iron-containing frame in contact with seaweed for a long time. The free iron elements in the frame will couple with the heavy metal elements to reduce the pollution of heavy metal elements. However, in actual application, the height of the current seaweed protection frame is generally fixed. The growth height of seaweed is different, and the sea water depth in different areas is also different, making the current protection frame unable to meet the growth needs of different seaweeds.
