Problems solved by technology

Extensive use of feed is the most important means to increase the production of aquaculture organisms. However, the accumulation of feed residues and aquaculture organism excreta has seriously polluted the aquaculture water.
The deterioration of aquaculture water not only affects the healthy growth of aquaculture organisms, but may even lead to their death, causing huge economic losses

Embodiment 1

[0010] An aquaculture water quality improver with good adsorption effect, the improver is composed of the following components and their weight components: 8-15 parts of oyster shell powder, 2-5 parts of activated carbon, 2-5 parts of diatomite, 5 parts of bentonite -10 parts, 5-10 parts of kaolin, 1-3 parts of zeolite, 0.01-0.1 parts of dodecyl dimethyl betaine, 0.01-0.1 parts of myristic acid, 3-7 parts of activated alumina, lauryl Dimethyl betaine and myristic acid play a role in promoting adsorption through activated carbon. At the same time, the water quality improver is spherical, with a rough surface and more pore structure. The specific surface area increases, which is more conducive to the adsorption of various pollutants. , so this embodiment is remarkable for water body improvement. The preparation method of the water quality improver for aquaculture comprises the following steps: washing the surface of oyster shells or discarded oyster shells from coastal Pacific O...

Embodiment 2

[0012] A kind of water quality improver for aquaculture, in parts by weight, comprises the following components:

[0013] 10 parts of oyster shell powder, 3 parts of activated carbon, 3 parts of diatomaceous earth, 8 parts of bentonite, 7 parts of kaolin, 2 parts of zeolite, and 4 parts of activated alumina.

[0014] Its preparation method comprises the following steps:

[0015] (1) Wash the surface of oyster shells from the coastal Pacific Ocean or discarded oyster shells with low-concentration hydrochloric acid;

[0016] (2) After washing, remove the impurities attached to the oyster shell raw materials;

[0017] (3) The oyster shells are crushed by a pulverizer and passed through a 100-mesh sieve, and dried and sealed for future use;

[0018] (4) The auxiliary materials include activated carbon, diatomaceous earth, bentonite, kaolin, zeolite, and activated alumina, which can be obtained from the market and sealed for future use;

[0019] (5) Mix 10 parts of the powder ob...

Embodiment 3

[0022] A water quality improver for aquaculture, in parts by weight, comprising the following components:

[0023] 12 parts of oyster shell powder, 4 parts of activated carbon, 4 parts of diatomaceous earth, 8 parts of bentonite, 6 parts of kaolin, 1 part of zeolite, and 5 parts of activated alumina.

[0024] Its preparation method comprises the following steps:

[0025] (1) Wash the surface of oyster shells from the coastal Pacific Ocean or discarded oyster shells with low-concentration hydrochloric acid;

[0026] (2) After washing, remove the impurities attached to the oyster shell raw materials;

[0027] (3) The oyster shells are crushed by a pulverizer and passed through a 100-mesh sieve, and dried and sealed for future use;

[0028] (4) The auxiliary materials include activated carbon, diatomaceous earth, bentonite, kaolin, zeolite, and activated alumina, which can be obtained from the market and sealed for future use;

[0029] (5) Mix 10 parts of the powder obtained i...

Abstract

The invention provides an aquaculture water quality improver, which is prepared from the following components in parts by weight: 8-15 parts of oyster shell powder, 2-5 parts of activated carbon, 2-5 parts of kieselguhr, 5-10 parts of bentonite, 5-10 parts of kaolin, 1-3 parts of zeolite, 0.01-0.1 part of dodecyl dimethyl betaine, 0.01-0.1 part of myristic acid and 3-7 parts of activated aluminum oxide. The aquaculture water quality improver is a compound water quality improver mainly for adsorbing heavy metals, and has good adsorption ability for several main pollutants in a water body, thus being used for improving aquaculture water quality. The water quality improver is spherical, is rough in surface, and has more pore structures; due to the enlarged specific surface area, the water quality improver is beneficial to absorption of various pollutants. The aquaculture water quality improver is low in cost, simple in preparation method and good in effect; furthermore, when in use, the aquaculture water quality improver does not cause secondary pollution, thus having higher exploitability.

Description

technical field [0001] The invention relates to an improver and a preparation method thereof, in particular to an aquaculture water quality improver and a preparation method thereof. Background technique [0002] In recent years, the aquaculture industry has developed very rapidly. However, a large amount of industrial wastewater, agricultural wastewater, and domestic sewage rich in heavy metals, nitrogen, and phosphorus have been discharged into rivers, rivers, and lakes, which has seriously deteriorated the ecological environment of the water area and made the aquaculture water environment worse. The problem of pollution has become increasingly prominent. The monitoring of most inland fishery waters by the National Fishery Ecological Environment Monitoring Network shows that the ecological environment of China's fishery waters is generally stable, and local pollution is serious. The main pollutants are nitrogen, phosphorus, petroleum and copper. The deterioration of the a...
