Abstract
The invention discloses a kind of diatomaceous earth purifier of fast purification marine culture water, the main points of its technical scheme are that quick marine culture water purifier is primarily of food grade kieselguhr and rice husk composition.Pulverizing, soaking and stirring, extruding oven dry, screening is helped to be packaged as finished product through micro-cutting.In absorption Water treatment, technology is helped to increase diatomite micropore canals and specific area by micro-cutting, the polluter of Adsorption particulate form and colloidal attitude, effectively can also reduce water turbidity and remove the harmful substances such as the major pollutants phosphorus of body eutrophication and ammonia nitrogen.Floating in marine culture water by this product, suspend and sink-float controllability, be conducive to the clean-up effect of water body 3 D stereo, be applicable to fast fall the water body purification that pH value, Adsorption of Heavy Metals etc. were denitrogenated, regulated and controled to ammonia in sea-farming process, the water purification being also applicable to marine ornamental fish water body uses.
Description
Technical field
The present invention, in aquaculture field, is specifically related to a kind of diatomaceous earth purifier of fast purification marine culture water.
Background technology
Seawater is the Essential Environment condition that marine cultured animal is depended on for existence, as the saying goes: " breeding fish for three points, seven points of foster water ".The quality of water quality directly has influence on their upgrowth situation and the economic benefit of raiser.Along with economy and the reach of science, the demand of people to aquatic products increases day by day, when amount of fishing can not be met the need of market, aquaculture was converted into present intensive culture mode by traditional extensive management, Resource Dependence type aquaculture mode already.But what the fast development propagated artificially along with high density height is intensive and breeding environment polluted increasingly sharpens, and makes the pollution level of aquaculture system considerably beyond the detergent power of water body self.Remaining bait and excreta deposit in water body, cause water body self-pollution and even water quality deterioration, show as: water body serious eutrophication, Suspended Matter in Water increases, the content of COD, ammonia nitrogen, nitrite nitrogen, hydrogen sulfide increases, harmful heavy metal content is accumulated, and dissolved oxygen declines, water acidification and the smelly end.Cause water body environment to worsen because water body inside produces the harmful substance of accumulation, the lighter is to the growth of aquatic economic animal, growth, breeding generation harmful effect; Then can cause time serious epidemic disease take place frequently and the death rate increase, finally cause aquatic product quality decline and output minimizing.
Water purification mode in existing seawater intensive culture process is generally adopt circulating filtration, and pond is fallen in clear pond, throws in chemical water purification agent and probiotics etc.But ubiquity is wasted time and energy and the shortcoming of high energy consumption high cost; Although worsen for the water body of burst, chemical water purification agent energy fast reaction transforms harmful substance, can cause secondary pollution to water body environment; Probiotics is environmentally friendly water purification scheme, but there is the inferior positions such as flora soak time length, Survival Reproduction bad adaptability and quantity minimizing.
Summary of the invention
The present invention will solve weak point in prior art, provides a kind of diatomaceous earth purifier of fast purification marine culture water.
Technical scheme of the present invention is as follows:
According to the batching of the diatomaceous earth purifier of fast purification marine culture water, by diatomite (mass percent 80-90%) by micro-cut help and do technical finesse mutually after, micro-the cutting of diatomite obtaining more than 500-600 order helps powder, carries out immersion 12-24 hour with adding water in rice husk (mass percent 10-20%) Mixed design fermentation vat; Mixture after soaking is inputted in extruser, being uniformly mixed rear extruding is nearly spherical shape medicine ball, the diameter control of medicine ball is at 2-6 millimeter, be transported to dryer to dry, after dry, the moisture of mixture is not higher than 10%, after obtaining required mixture medicine ball, be packaged as the finished product of the diatomaceous earth purifier of fast purification marine culture water.
Diatomite is a kind of biogenic silicastone, primarily of ancient times diatom remains composition, in diatom have many different shapes, as discoid, needle-like, tubular, pinniform etc., its chemical analysis mainly SiO
2, the good characteristics such as voidage is high, specific surface is large, proportion is little owing to having, wear-resisting, acidproof, adsorptivity is strong, thermal conductance is low, heat-insulating flame-retardant, heat preservation and soundproof, are widely used in the industries such as diet, building materials, chemical industry, the energy, water treatment.
Diatomite has the large characteristic of specific area, and the larger adsorbance of specific area is larger; Aperture is larger, and the diffusion rate of adsorbance in hole is larger, then be more conducive to reaching adsorption equilibrium.And diatomaceous surface and internal surface of hole are distributed with a large amount of silicone hydroxyl, these silicone hydroxyl in aqueous dissociation go out H
+, thus make particle performance go out certain surperficial elecrtonegativity, make it in water treatment procedure, not only can remove the polluter of particulate form and colloidal attitude, effectively can also reduce major pollutants phosphorus and the ammonia nitrogen of water turbidity and removal body eutrophication, and Hg
2+, Pb
2+, Cr
6+, Cd
2+, Cu
2+etc. harmful substances such as heavy metal ion.
Rice husk is one deck shell outside paddy, by inner glume and larger coetoniumly to form.The long 5-10mm of rice husk, 2.5-5mm, thick 23-30 micron, its color and luster is generally in golden yellow, and after pulverizing, bulk density can reach 384-400kg/m
3.
Rice husk is rich in cellulose, lignin, silica, and wherein the content of fat, protein is very low, is mainly used to do fuel, filler bedding and padding, mushroom growth base and feed addictive.As the auxiliary material of this product, the floatability of product, suspension and sink-float controllability can be increased, be conducive to the clean-up effect of marine culture water 3 D stereo.
On existing market, marine culture water purification preparation mainly contains the large class of chemical reagent class and probiotics two, but all ubiquity certain defects.Although such as chemical reagent water purification is fast, efficiency is high, simultaneously to secondary environmental pollution and aquaculture organism toxic and side effect; Although the harmless safety of probiotics, sluggish, tolerance is poor.This product adopts natural non-metallic mineral, nontoxic, physical absorption, efficient quick, and inertia is strong, and cost is low, acute water body pollution is had to the purifying water effect of efficient quick safety.
