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 method for modifying bottom of an aquaculture pond and specifically relates to a pure natural flocculant for modifying the bottom of the aquaculture pond and a preparation method of the pure natural flocculant for modifying the bottom of the aquaculture pond. The pure natural flocculant for modifying the bottom of the aquaculture pond comprises the following components in parts by weight: 30-40 parts of paddy shell, 21-27 parts of beanstalks, 21-28 parts of sweet potato leaves, 20-25 parts of starch, 18-25 parts of folium mori, 15-22 parts of isoachlya, 12-17 parts of banana skin, 12-18 parts of galactomannan gum, 11-18 parts of bentonite and 9-15 parts of zeolite powder. The pure natural flocculant has the advantages of excellent bottom modifying effect, natural and nontoxic effect and no secondary pollution.

Description

technical field [0001] The invention relates to a method for improving the bottom of aquaculture ponds, in particular to a pure natural flocculant for bottom improvement of aquaculture ponds, and also to a preparation method for the above-mentioned pure natural flocculant for bottom improvement of aquaculture ponds. Background technique [0002] After the pond has been used for a certain period of time, a certain amount of residual bait and aquaculture animal feces have accumulated at the bottom of the pond. After they are decomposed, they interact with the sediment at the bottom under the biological interaction to form a certain thickness of bottom mud. This kind of sediment can not only supply and preserve fertilizer, but also regulate and buffer the deterioration of pond water to a certain extent. However, when a large amount of bait is fed in the breeding pond after a period of time, the remaining bait and animal feces will be deposited on the bottom of the pond, and the...
