Abstract

The invention relates to the technical field of mariculture, in particular to flue gas desulfurization gypsum for the mariculture and a preparation method thereof. The flue gas desulfurization gypsum for the mariculture is prepared from, by weight, 1-3 parts of microbial enzymes, 5-8 parts of sepiolite, 7-12 parts of feed grade zeolite powder, 9-11 parts of rice husks, 0.5-1.5 parts of biological bacterium fluid, 75-84 parts of flue gas desulfurization gypsum, 0.8-1.6 parts of lactobacillus acidophilus and 0.6-2 parts of photosynthetic bacteria. According to the flue gas desulfurization gypsum for the mariculture and the preparation method thereof, the microbial enzymes, sepiolite, feed grade zeolite powder, rice husks, biological bacterium fluid and flue gas desulfurization gypsum serve as the main ingredients to be prepared into the flue gas desulfurization gypsum for the mariculture, and by means of the sepiolite, feed grade zeolite powder and rice husks contained in the flue gas desulfurization gypsum for the mariculture, the improved flue gas desulfurization gypsum can improve magnesium chloride and sodium chloride in seawater to meet the requirements of the mariculture; the preparation method of the flue gas desulfurization gypsum for the mariculture is simple, and the raw material cost and production cost are low.

Description

technical field [0001] The invention relates to the technical field of mariculture, in particular to a desulfurized gypsum for mariculture and a preparation method thereof. Background technique [0002] Mariculture is an industry in which humans use shallow seas and tidal flats to artificially breed marine animals. Mariculture has formed a huge industry category in the world, and 80% of the human seafood supply is provided by the mariculture industry. However, at the same time, because mariculture requires frequent water changes in the culture ponds, mariculture has become one of the main causes of algal blooms in various countries, leading to red tides. [0003] Desulfurization gypsum is also known as exhaust gas desulfurization gypsum, sulfur gypsum or FGD gypsum. The main component is the same as natural gypsum, calcium sulfate dihydrate CaSO4.2H2O, with a content of ≥93%. Desulfurization gypsum is an industrial by-product gypsum obtained by coal or oil-burning industri...
