Most of the phytophagous fishes feed on phytoplankton or organic matters in water and bottom sediment, heavy metals in the phytophagous fishes can be accumulated in different tissues and organs of the phytophagous fishes through the action of biological enrichment, and the fishes can further enrich the heavy metals in the bodies of the fishes through the modes of respiration of gills, permeation of skins, ingestion of the aquatic animals and plants polluted by the heavy metals and the like, so that the negative influence on the growth and development of the fishes is generated, and certain potential safety hazards also exist for consumers. This phenomenon is also more pronounced with the food chain, and therefore the content of heavy metal species at the top of the food chain is higher.
Along with the urbanization, more and more fishery clusters appear, so that the concentrated slaughtering of aquatic products is caused; with the help of nutriologists, fishery processing factories have the ability to select edible parts, so that the risk of eating heavy metals by people is avoided to a greater extent; however, how to treat the waste becomes a more troublesome problem for the processing plant. There are generally two approaches to the disposal of these wastes: the feed is used for breeding other animals; secondly, the treated fertilizer is used as a fertilizer in agricultural production. The treatment of heavy metals in the waste cannot be exceeded by the two aspects, and if the treatment is improper, the risk is caused to the health of human beings.
In the prior art, the chinese patent with application number 201410002729.2 discloses a method for degrading heavy metals in the process of temporarily rearing aquatic animals, which is to add compound fish vitamins, or EDTA, or a mixture of compound fish vitamins and EDTA into the feed during temporarily rearing aquatic animals; the addition amount of the compound vitamin in the feed is 4-10 g/Kg; the addition amount of EDTA is 1.0-3.2 g/Kg.
The Chinese patent with the application number of 201910945380.9 discloses a harmless treatment method for strengthening heavy metal removal of aquaculture tail water, which comprises the following steps: 1) arranging a planting pot on the floating bed, wherein the planting pot is provided with an interlayer, the interlayer is filled with a permeable protective layer, and the side wall of the planting pot is provided with permeable holes; 2) mixing the modified mineral adsorbent with soil to prepare composite soil; 3) planting the water cress seedlings in the planting pots by using composite soil; 4) putting the floating bed into a culture pond; 5) pulling out the grown mature cress with roots, planting new cress seedlings in a planting pot, and ridging by using composite soil; 6) repeating the step 4) and the step 5). The modified mineral adsorbent adsorbs heavy metal ions in the aquaculture water, and the rhizome of the cress adsorbs the heavy metal ions in the composite soil, so that the heavy metal ions in the aquaculture tail water can be timely treated.
In order to ensure food safety and realize green environmental protection, the aquatic product waste heavy metal treatment agent which is simple and convenient and has strong degradation capability needs to be developed.
