preparation example Construction

[0033] In order to better demonstrate the preparation method of a substrate modifier that can build a sediment micro-ecosystem in advance, in this example, a method for preparing a substrate modifier that can build a sediment micro-ecosystem in advance includes the following steps :

[0034] Step 1: Put the shells of the molluscs of the Lepidoptera class and the animals of the subphylum Crustacea into a dryer for drying;

[0035] Step 2: Put the dried shells of the clambranchus mollusks and the animals of the subphylum Crustacea into a pulverizer for 2-4 hours, and then pass them through a 300-400 mesh sieve to obtain animal powder;

[0036] Step 3: Dry the activated iron oxide and activated alumina in a dryer:

[0037] Step 4: Put the dried activated iron oxide and activated alumina into a pulverizer to grind for 1-2 hours, and then pass it through a 100-400 mesh sieve to obtain a chemical powder;

[0038] Step 5: Put the activated carbon into a grinder and grind it for 0.5...

Embodiment 1

[0041] Step 1: Dry the oyster shells and crab shells in a dryer;

[0042] Step 2: put oyster shells and crab shells into a grinder and grind them for 2 hours, and then pass them through a 300-400 mesh sieve to obtain animal powder;

[0043] Step 3: Dry the activated iron oxide and activated alumina in a dryer:

[0044] Step 4: Put the dried activated iron oxide and activated alumina into a pulverizer to grind for 1 hour, and then pass it through a 100-400 mesh sieve to obtain a chemical powder;

[0045] Step 5: Grinding the activated carbon in a pulverizer for 0.5 hours, and then passing it through a 400-1000 mesh sieve to obtain activated carbon particles;

[0046] Step 6: Mix animal powder, chemical powder and activated carbon particles, prepare an appropriate amount of liquid, and then put it into a granulator for granulation to obtain a substrate modifier.

[0047] In this embodiment, oyster shells and crab shells are used to generate biological calcium carbonate and chi...

Embodiment 2

[0049] Step 1: Put the mussel shells into the dryer to dry;

[0050] Step 2: Put the mussel shells into a grinder and grind them for 3 hours, and then pass them through a 300-400 mesh sieve to obtain animal powder;

[0051] Step 3: Dry the activated iron oxide and activated alumina in a dryer:

[0052] Step 4: Put the dried activated iron oxide and activated alumina into a pulverizer to grind for 1.5 hours, and then pass it through a 100-400 mesh sieve to obtain a chemical powder;

[0053] Step 5: Grinding the activated carbon in a grinder for 1 hour, and then passing it through a 400-1000 mesh sieve to obtain activated carbon particles;

[0054] Step 6: Mix animal powder, chemical powder and activated carbon particles, prepare an appropriate amount of liquid, and then put it into a granulator for granulation to obtain a substrate modifier.

[0055] In this embodiment, mussel shells are used to generate biological calcium carbonate and chitin, which not only has low cost of ...

Abstract

The invention discloses a substrate modifier capable of constructing a bottom mud micro-ecosystem in advance, and a preparation method thereof. The substrate modifier comprises, by weight, 20-30 parts of biological calcium carbonate; 10-20 parts of chitin; 30-40 parts of activated carbon; 5-10 parts of active iron oxide; 5-20 parts of activated aluminum oxide; and a proper amount of liquid. According to the substrate modifier capable of constructing the bottom mud micro-ecosystem in advance and the preparation method thereof, the main component of a shell of a branchiomycota mollusk is calcium carbonate, and the shell has a unique microporous structure, has relatively high adsorption performance and can adsorb harmful organic impurities precipitated in a water body, and meanwhile, chitin of a carapace animal can release negative oxygen ions, the negative oxygen ions can decompose and purify pollutants in a water body and increase the oxygen content of the water body, and the two raw materials can be supplied in restaurants and are low in cost, so that the cost of the substrate modifier is reduced, and meanwhile, the substrate modifier has excellent environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of substrate improving agents, in particular to a substrate improving agent capable of constructing sediment micro-ecosystems in advance and a preparation method thereof. Background technique [0002] Substrate improver is a reagent to improve the water quality of aquaculture farms. The existing substrate improvers are divided into five types, including adsorption type, flocculant type, ion interaction type, live bacteria degradation type and chemical degradation Different types of substrate improvers are suitable for different water qualities. Taking the adsorption type as an example, it mainly uses materials with good adsorption capacity to adsorb harmful substances such as ammonia nitrogen, nitrous acid, and organic matter in water. However, the existing adsorption type In the production process of the substrate modifier, most of its raw materials are zeolite powder, medical stone and activated carbon. Th...
