Problems solved by technology

For example, the artificially synthesized flocculant-polyacrylamide monomer has neurotoxicity and "three causes" effects (teratogenic, carcinogenic, mutagenic), aluminum salts are toxic and will affect human health, and iron salts will cause damage to treated water. After the color, the high concentration of iron will also be harmful to human health and the ecological environment, so the development of a natural non-toxic flocculant that will not cause secondary pollution has important production significance and market prospects

Abstract

The invention relates to a natural and efficient bottom-modifying flocculating agent and a preparation method thereof. The bottom-modifying flocculating agent is formed by preparing the following components including, by mass, 30-40 parts of sweet potato leaves; 20-27 parts of beanstalk, 20-27 parts of viva pertusaje, 6-9 parts of bentonite, 2-3 parts of vermiculite, 1-4 parts of winter jasmine, 5-7 parts of Chinese holly, 20-25 parts of potatoes, and 10-15 parts of folium eucalypti. The natural and efficient bottom-modifying flocculating agent and the preparation method thereof have the advantages that the flocculating agent is good in flocculating effect, environmentally friendly and free of poison.

Description

technical field [0001] The present invention relates to the technical field of aquaculture, in particular to a natural and efficient bottom reformed flocculant, and also relates to a preparation method of the natural and efficient bottom reformed flocculant. Background technique [0002] With the development of the economy and the rapid growth of the world population, the human demand for animal protein is increasing day by day, and because the catch is limited by the renewal of natural fishery resources, aquaculture is playing an increasingly important economic role. However, with the continuous expansion of aquaculture scale and the rapid increase of output, a series of ecological and environmental problems have gradually emerged. Residual bait, wreckage, fish and shrimp body excrement, etc. produced in the aquaculture process have led to hypoxia in the substrate environment, accumulation of harmful substances, deterioration of the bottom environment, and increasingly seri...
