Abstract

The invention provides a chemical oxygen supply scavenging agent to solve the problem of cultured product death caused by insufficient dissolved oxygen in water and deterioration of water quality in the aquaculture process. The scavenging agent comprises 10-70% of oxygen supply agents, 0-30% of curing agents, 10-15% of pH value regulating agents, 2-8% of release agents, 0-2% of stabilizing agents and 0-10% of catalyst by weight. The oxygen supply scavenging agent is soluble in water and is neutral, can effectively supply oxygen, does not contain harmful substances and is convenient to use.

Description

Aquaculture oxygen supply scavenging agent

Technical field

The present invention relates to a kind of oxygen supply and scavenging agent of used for aquiculture.

Background technology

Greatly develop aquatic products high-density breeding, industrialized culture and in fish transportation, storage process, often can produce minute in the problem that degenerates of oxygen-supplying amount wretched insufficiency and water quality, thereby cause fish because suffocating and poison death.For addressing the above problem, adopt changed water law or mechanical enhancement more both at home and abroad, the oxygen cylinder oxygenation methods, these method costs of dawn of adopting high more during transportation of live fish, using inconvenience to popularize is restricted, for this reason, began in the last few years to adopt the agent of chemistry arch oxygen abroad, and namely cooperated with auxiliary agent with superoxide and make different dosage form, produce oxygen in aborting, with the deficiency of dissolved oxygen amount in the moisturizing.But existing chemical oxygenate still has the some shortcomings part. if any oxygenate select sodium peroxide or Potassium peroxide, but this two kind of material is strong basicity after water-soluble, and high price, processing units required high, therefore, this class oxygenate is difficult for commercialization.Some oxygenates are selected Sodium peroxoborate, but it must could give birth to oxygen when water temperature is higher, being actually infeasible. some are the oxygenate as leading take calcium peroxide or alkaline earth metal peroxide, all cooperate organic acid or heavy metal catalyst to use, or in manufacturing processed, use volatile organic solvent, and use the organic acid cost high, use heavy metal catalyst harmful to fish, use volatile solvent can cause atmospheric pollution during manufacturing. also reporting in the patent documentation has take SPC-D as main oxygenate, but its aqueous solution is strong basicity, improper use will cause fish kills, its auxiliary agent is adopted boudoir Manganse Dioxide simultaneously, the objectionable impuritiess such as potassium permanganate, they can remain in fish and read in the body, and the eater is caused secondary pollution.

In addition, in many dress dry permeability containers, it was not quite convenient to use when aforementioned oxygenate used, and rear oxygen diffusion is also inhomogeneous in the input water.

For overcoming the weak point of existing oxygenate, a kind of dissolved oxygen amount that can effectively increase in the water is provided, can purify water again, novel oxygen supplying and water clarifying agent simultaneously easy to use, the spy finishes the present invention.

Summary of the invention

The weight ratio of contained each component of oxygen supplying and water clarifying agent of arch that the present invention carries is as follows,

Oxygenate (SPC-D, calcium peroxide) 10-17%

P value adjusting agent (potassium primary phosphate, SODIUM PHOSPHATE, MONOBASIC, zinc sulfate, sal epsom, Calcium Chloride Powder Anhydrous 10-15%

Solidify chaste tree (gypsum, Calucium Silicate powder) 0-30%

Remover (graphite, talcum powder, hard magnesium acetate) 2-8%

Fringe is decided agent (silicate, phosphoric acid salt) 0-2%

Catalyzer (ferric oxide) 0-10%

Said components is pieced together through baking., pulverizing, batch mixing,, compressing tablet or granulation get product.

Chemical oxygen supplying and water clarifying agent master ticket composition provided by the present invention be the required nutritive element of fish,

The water-soluble neutrality that is, do not contain harmful matter matter, can not poison water quality, and can be with oxygenolysis such as the hydrogen sulfide that rots to produce because of the row pond thing of remaining bait, fish and organism in the water, sulphite, and wash according to different purposes and to select different prescriptions and agent l type can be controlled oxygen time and the speed of putting effectively, directly carry during use and spread, very convenient.

Be placed on respectively in 2500 milliliters of encloses containers with each five of goldfish, add 1000 milliliters in water and be the contrast experiment. throw in five of this oxygen supply water purification tablets (every 1 gram) for one group, another organizes blank.

Control group second day water is muddy, and goldfish only survived five days, and input group one all rear water just begins to become mixed, goldfish survival fortnight.

Embodiment

Example 1, be used for the oxygen supplying and water clarifying agent of living food long-distance transport, storage, obsevational fish cultivation, this is as follows for minute weight:

Calcium peroxide (active oxygen, 17.6%) 23.5%; Gypsum (or Calucium Silicate powder) 23.5%; Potassium primary phosphate 44%

Ferric oxide 4%; Talcum powder 2.9%; Tertiary sodium phosphate 1.3%;

After said components mixes, use the tabletting machine compressing tablet, make a moment of Φ I2 millimeter, thick 5 millimeters, heavy 0.9-1.0 gram.

The dried pond fish floating head that prevents of example 2 usefulness, rice field fish culture, oxygen supply under water in ice-bound season prevents that the coastal waters from the long-acting oxygen supplying and water clarifying agent of red tide occuring, its each components by weight is as follows:

Calcium peroxide (active oxygen 17.6%) 29.6%

Gypsum 22.2%

Zinc sulfate 44.4%

Graphite 2.0%

Tertiary sodium phosphate 1.8%

Said components uses first 10 tons/cm2 pressing machine to be pressed into sheet, and then is ground into the particle of φ 4 millimeter, then obtains active oxygen greater than 5% oxygen supplying and water clarifying agent.

Example 3, the first-aid oxygen supply water purification agent when being used for pond fish generation floating head, its each components by weight is as follows:

SPC-D (active oxygen〉14%) 69.0%

Calcium Chloride Powder Anhydrous 27.5%

Talcum powder 2.0%

Tertiary sodium phosphate 1.5%

Said components uses first 10 tons/cm2 pressing machine to be pressed into sheet, and then is ground into the particle of φ 4 millimeter, then obtains active oxygen greater than 9% SWater purifying agent with quick result.

Claims

1. an aquaculture is characterized in that with oxygen supply scavenging agent water purification chaste tree its Chu Zufen and heavy basin are such as lower: oxygenate (SPC-D, calcium peroxide) 10-17%; P value adjusting agent (potassium primary phosphate, SODIUM PHOSPHATE, MONOBASIC, zinc sulfate, sal epsom, Calcium Chloride Powder Anhydrous 10-15%; Solidify chaste tree (gypsum, Calucium Silicate powder) 0-30%; Remover (graphite, talcum powder, hard magnesium acetate) 2-8%; Fringe is decided agent (silicate, phosphoric acid salt) 0-2%; Catalyzer (ferric oxide) 0-10%.
