Abstract

The invention discloses a red mud/Yellow River sediment artificial fish reef and a preparation method thereof, and belongs to the field of comprehensive utilization of solid waste resources. Raw materials comprise 100-400 parts of red mud, 100-400 parts of Yellow River silt, 30-100 parts of mineral powder, 50-200 parts of shells, 15-25 parts of an exciting agent and 25-80 parts of mixing water. The preparation method comprises the following steps: firstly, adding water glass as an exciting agent into mixing water to prepare a uniformly dispersed water glass aqueous solution; secondly, adding an aqueous solution into the red mud, the yellow river sediment, the mineral powder and the shell mixture for stirring, and carrying out compression molding on the stirred yellow river sediment slurry casting mold; and finally, maintaining the sample in an air environment, and removing the mold. Compared with a common cement concrete artificial fish reef, the preparation and production cost of the artificial fish reef is effectively reduced, meanwhile, the artificial fish reef has good strength and durability, and the alkalinity of the system is low. Comprehensive utilization of solid waste resources is promoted, the production cost of the artificial fish reef is reduced, other properties such as durability of the artificial fish reef are improved, and the artificial fish reef has remarkable environment-friendly, economic and engineering utilization values.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of solid waste resources, and designs an artificial fish reef, in particular to an artificial fish reef based on red mud / Yellow River sediment and a manufacturing method thereof. Background technique [0002] The core and main facility of the ocean ranch is the artificial reef. Artificial reefs are man-made structures in the sea, and are an important technical means for the construction of marine ranches. Artificial reefs can provide places for fish to reproduce, grow, feed and shelter, and protect and proliferate fishery resources. Reasonable artificial reef construction is conducive to adjusting the structure of the marine industry, restoring and improving the marine ecological environment, multiplying and optimizing fishery resources, and promoting the sustainable and healthy development of the marine economy. At present, the main raw material for the construction of artificial reefs...
