Description
Technical field
The present invention relates to a kind of modifying agent and preparation method thereof, more particularly, to a kind of improver of water quality used for aquiculture and
Its preparation method.
Background technology
In recent years, the development of culture fishery is very rapid, however, largely rich in heavy metal, nitrogen, the industrial wastewater of phosphorus,
Agricultural effluent and sanitary sewage are entered in river, river, lake water, cause water area ecological environment severe exacerbation, also make cultivation water environment dirty
Dye problem becomes increasingly conspicuous.National Survey of Fishery Ecological Environment net shows the monitoring that most of inland fishery waters is carried out, Chinese
The state of ecological environment of fisheries water totally keeps stabilization, and local pollution is more serious, major pollutants be nitrogen, phosphorus, petroleum-type and
Copper.The deterioration of breeding ecological environment, easily causes the generation of various aquatic products diseases, is caused to culture fishery different degrees of
Economic loss, it has also become one of key factor that restriction China culture fishery develops in a healthy way.
As the continuous popularization of aquatic products intensive culture technology, pond culture density are increasing, specific yield is significantly increased, cultivation
Economic benefit is significantly improved.A large amount of is to improve the most important means of aquaculture organism yield using feed, but feed is residual
The accumulation of bits and aquaculture organism excreta generates serious pollution to breeding water body.The deterioration of breeding water body not only has influence on foster
The healthy growth of biology is grown, its death is resulted even in, huge economic loss is caused.Science carries out changing for breeding water body water quality
It is good, it is to improve breed variety growth quality, reduce disease and occur, the key of the excellent product of high yield is realized, and improver of water quality is undoubtedly
The important dependence of breeding water body regulating and controlling water quality.
The principle of the water quality of improver of water quality improvement both at home and abroad is broadly divided into 3 kinds at present：Physical absorption, refers to using with absorption
The raw material of property is adsorbed to the pollutant in water body, with to secondary pollution of water it is small the characteristics of；Chemical method, refers to utilizationization
Learn medicine to improve water quality, feature is rapid effect, and effect substantially, but can cause some to damage environment；Biological method, refers to
The nitrifying bacteria community in water is set to form population advantage using biological agent.Conventional improver of water quality mainly has following a few classes at present：
Quick lime and calper calcium peroxide, natural minerals modifying agent, biological modification agent, flocculant.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of with good adsorption effect, and absorption is quick, will not
Produce the improver of water quality used for aquiculture and preparation method simple to operate, cheap of secondary pollution.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of aquatic products with good adsorption effect is supported
Grow and use improver of water quality, modifying agent is made up of following composition and its components by weight percent：Oyster shell powder 8-15 parts, activated carbon 2-5 parts, silicon
Diatomaceous earth 2-5 parts, bentonite 5-10 parts, kaolin 5-10 parts, zeolite 1-3 parts, dodecyldimethylammonium hydroxide inner salt 0.01-0.1 parts,
Myristic acid 0.01-0.1 parts, activated alumina 3-7 parts.The preparation method of improver of water quality used for aquiculture, including following step
Suddenly：Coastal Pacific oyster shell or discarded oyster shell will be taken from, surface is cleaned with low-concentration hcl；After cleaning, go
Except impurity subsidiary in oyster husk as raw material；100 mesh sieves are crossed after the size-reduced machine of oyster shell is crushed, sealing preserve is dried standby；Press
Above-mentioned components by weight percent weighs activated carbon, diatomite, dodecyldimethylammonium hydroxide inner salt, myristic acid, bentonite, kaolin, boiling
Stone, activated alumina sealing preserve are standby；Powder obtained above is mixed by a certain percentage with auxiliary material, suitable quantity of water is added and is glued
Mixture, water is ultra-pure water, is sufficiently stirred for, and after mediating uniformly, obtains sticky powdered improver of water quality used for aquiculture；Will be above-mentioned
The sticky powdered improver of water quality used for aquiculture for obtaining prepares spherical sample particle in being put into pellet processing machine, is placed in Muffle furnace
Middle calcining at constant temperature, Muffle furnace calcining heat is 550 DEG C, and calcination time is 2 h, and sealing preserve after cooling obtains form of spherical particles
Improver of water quality used for aquiculture.
The invention has the advantages that：The present invention is the compound improver of water quality based on Adsorption of Heavy Metals, in water body
Several major pollutants there is good adsorption capacity, can be used for cultivation water improvement.Improver of water quality is in spherical, and surface is thick
Rough, with more pore structure, specific surface area increase is conducive to the absorption to various polluters.The improver of water quality into
This is cheap, and preparation method is simple, works well, and will not produce secondary pollution when in use, with stronger exploitability.
