Abstract
Ferrous ion source is prevented and kill off hydrogen sulfide in the sea farming.The invention belongs to galvanic cell speed and give birth to ferrous ion, the novel method of preventing and kill off hydrogen sulfide with culturing that sulfonium ion and hydrogen sulfide in the pond form the Iron sulfuret precipitation.This method is made negative pole with iron, is anodal with indissoluble electrode materialss such as copper, graphite, nickel, edge platinum, titanium-based noble metals, and two electric pole short circuits join, and are electrolytic solution with the flowing seawater.Prevent and kill off with method of the present invention and to culture hydrogen sulfide in the pond, device is simple, less investment, fast, convenient, easy row.Through facts have proved, can reach the water quality standard of national regulation, and replenish and propagated middle source of iron key element artificially.
Description
The present invention belongs to a kind of open type flowing electrolyte battery to produce the novel method that ferrous ion is prevented and kill off hydrogen sulfide in the sea farming fast.
Hydrogen sulfide in the sea farming is because the tired organic matter of pond prodelta clay, forms as the putrid fermentation of residual bait, planktonic skeleton of a corpse, biological metabolite etc.Hydrogen sulfide is a kind of toxic gas, and its existence not only can influence the growth of aquaculture organism, and can jeopardize the life of aquaculture organism.In aquaculture, the content of hydrogen sulfide is very important water-quality guideline in the water, and the water quality standard for fishery that China is drafted is that the content of hydrogen sulfide is no more than 0.1ppm.For preventing and kill off of hydrogen sulfide in the sea farming, external at present the employing at the bottom of culturing the pond by 1 kilogram/meter
2Consumption apply the iron protoxide of 75% purity, with removal of hydrogen sulfide, generation produce the Iron sulfuret precipitation.Facts have proved that this method is effective, but because of its price height, it is unpractiaca using, and therefore can not use in the big area sea farming.The domestic people of having once adopted at the bottom of culturing the pond by 1.5 kilograms/meter
2Consumption applies the ironmaking slag, and its effective ingredient is a ferric metasilicate etc., but because of sulfur-bearing and other detrimental impurity in the ironmaking slag, is that more harm than good to aquaculture organism, can not adopt.Up to the present, be subjected to the harm of hydrogen sulfide both at home and abroad in the aquaculture industry, its method for control is not resolved as yet always.
The objective of the invention is to obtain a kind of less investment, fast, convenient, produce method easily to the favourable ferrous ion of aquaculture organism, adopt this method ferrous ion that produces and the sulfonium ion and the hydrogen sulfide reaction of culturing in the pond, generation Iron sulfuret precipitation, thus reach prevention and eliminate the purpose of culturing hydrogen sulfide in the pond.
Main points of the present invention are to adopt galvanic cell to produce ferrous ion.
Negative pole: iron pipe or iron plate
Anodal: insoluble electrode materialss such as copper, graphite, nickel, edge platinum, titanium-based noble metal, respective negative makes tubulose or tabular.
Electrolytic solution: flowing seawater
Assembling mode: open type
In actual applications, two electric pole short circuits are joined, thereby reach the purpose that speed is given birth to ferrous ion.
Adopt method of the present invention to prevent and kill off hydrogen sulfide in the sea farming, its device is simple, only need to make negative pole with iron pipe or iron plate, with insoluble electrode materialss such as copper, graphite, nickel, edge platinum, titanium-based noble metals, affected tubulose of respective negative or tabular work positive pole, be fixed on the bait throwing in ship of mobile operational process or seawater inlet gate place, long service life, only need one-time investment, easy to use, can make apace in the whole breed pond and obtain ferrous ion equably, reach the purpose of comprehensively preventing and kill off hydrogen sulfide in the pond.According to the actual sulphur content that records in the breeding process, the equivalent relation by reaction applies excessive ferrous ion, precipitated sulfur ion fully, and preventive effect reaches 100%.
Embodiment: in the prawn culturing process, the actual ferrous ion source apparatus that adopts is that the iron pipe long 1 meter with 10, that diameter is φ 36mm * 5mm is made negative pole, long 1 meter with 10, diameter is that the copper tube of φ 8mm * 1mm is done anodal, the copper pipe symmetry is inserted in the iron pipe, short circuit is joined, constitute the electrode electricity to and form open type electrode electricity to group.Time spent immerses and cultures in the pond, with the flowing seawater is ionogen, along with the paddling of bait throwing in ship just can produce ferrous ion continuously, apace, series of cells and culturing pool mask have certain obliquity, water surface was advisable for 5～10 centimetres at the bottom of the size of its gradient was pressed close to the pond with series of cells one end, be furnished with elevating lever with the bait throwing in ship place of linking on the series of cells anchor, adjustable-height is with the injustice at the bottom of the adaptation pool (as circular groove and Di Tan).Facts have proved that the present invention is remarkable to the effect of preventing and kill off the hydrogen sulfide in the shrimp culture pond, the field measurement data are as follows:
Concentration of hydrogen sulfide is 0.0003ppm among the Chi Shui.
Come-up water cure hydrogen concentration is 0.018ppm at the bottom of the pond.
Bed mud top layer, pond interstitial water concentration of hydrogen sulfide 0.29ppm.
Pond bed mud 5 centimeters concentration of hydrogen sulfide 0.35ppm.When the concentration of hydrogen sulfide that above-mentioned data and luxuriant open country (1975) are found out with experiment was 0.1～2.0ppm, prawn lost self balance, and the dead immediately water quality standard of prawn compares under the concentration of 4ppm, all in safety range, obtains good harvest over the years.
Claims (4)
1, ferrous ion source is prevented and kill off hydrogen sulfide in the sea farming, it is characterized in that adopting galvanic cell speed to give birth to ferrous ion and the sulfonium ion and the hydrogen sulfide reaction of culturing in the pond, generates the Iron sulfuret precipitation, thereby prevents and kill off the hydrogen sulfide of culturing in the pond.
