Efficient artificial algal reef using tidal flat mud as raw material and preparation method of efficient artificial algal reef

Abstract

The invention provides efficient artificial algal reef using tidal flat mud as a raw material and a preparation method of the efficient artificial algal reef. The efficient artificial algal reef is characterized in that the artificial algal reef is prepared by using the characteristic that the tidal flat mud is rich in nutrient salt components such as nitrogen, phosphorus and the like and referring to dissolution rules of nutrient salt substances under different mass proportions of mud and cement. The invention also provides a preparation method of the tidal flat mud raw material. By adopting the method, the mass of obtained mud can account for 15-30% of the total mass of the algal reef, the corresponding compressive strength is between 25Mpa and 30Mpa, and the total utilization rate of the tidal flat mud can reach more than 20%. According to the efficient artificial algal reef, the nutrient salt components such as nitrogen, phosphorus and the like can be continuously dissolved from the internal part of a reef body, attachment and fixation matrixes of algae and spores of the algae can be provided, and good nutritional environment for survival and growth of the algae and the spores of the algae also can be provided. The efficient artificial algal reef provided by the invention can be used for reducing the application amount of materials such as cement and the like and reducing the alkalinity of artificial algal reef concrete, also has an important significance in repairing natural landscapes of tidal flat areas, achieves the aims of energy conservation and emission reduction, and is beneficial for improving the compatibility between the artificial algal reef and the marine ecological environment.

Description

technical field [0001] The invention relates to a high-efficiency artificial algae reef using beach mud as raw material and a preparation method thereof. Background technique [0002] The decline of fishery resources, the signing of international fishery agreements, and the increasing demand for aquatic products have promoted the development of conservation and restoration of offshore fishery resources, and the conversion of fishermen to other industries. The construction of facility fisheries with artificial reefs as the core has gradually become an important way to alleviate a series of problems. [0003] As a kind of artificial fish reef, artificial algae reef is an underwater structure set up to improve the breeding environment of marine algae, proliferate and protect fishery resources. There are many kinds of construction materials, and the adhesion effect and proliferation performance are also different. At present, in the research on the construction of artificial a...

Problems solved by technology

However, at present, the materials used in the preparation of artificial algal reefs in my country are still mainly concrete and block stones, and there is little research on the application of tidal mud in the preparation of artificial algal reefs.
