Abstract
The invention discloses a zeolite water purifier for rapid purified seawater aquatic water. According to the technical scheme, the rapid seawater aquatic water purifier is mainly characterized by containing feed-grade zeolite powder and rice hull which are made into a finished product by smashing in a mechanochemical assisting mode, soaking, stirring, extruding, drying, screening and packaging, wherein the micro-pore channels of zeolite crystal molecules are increased through a mechanochemical assisting technique in the purified water filtering process, harmful substances such as ammonia nitrogen and nitrite in the aquatic water are effectively adsorbed in a physical mode, and the zeolite water purifier is strong in affinity with harmful polar gas molecules such as SO2, NH3 and H2S in the seawater aquatic water since great electrostatic attractive force and field of stress are formed inside the modified zeolite. Due to floating, suspension and up-and-down construability of the product in the seawater aquatic water, a three-dimensional water purification effect is achieved, the purifier is applicable to water purification for rapidly and conveniently reducing amino, removing nitrogen, stabilizing the pH value, adsorbing heavy metal and the like in the seawater aquatic process, and the purifier is also applicable to purification of seawater aquarium fish water.
Description
Technical field
The present invention, in aquaculture field, is specifically related to a kind of zeolite water purification agent 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: " within three minutes, breeding fish, seven minutes foster water ".The quality of water quality directly has influence on their upgrowth situation and raiser's economic benefit.Along with economy and the reach of science, people increase day by day to the demand of aquatic products, in the situation that 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.Yet, along with increasingly sharpening that the high intensive fast development of propagating artificially of high density and breeding environment pollute, make 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: the serious eutrophication of water body, Suspended Matter in Water increases, the content of COD, ammonia nitrogen, nitrite nitrogen, hydrogen sulfide increases, harmful heavy metal content accumulation, dissolved oxygen declines, water acidification and the smelly end.Because the inner harmful substance that produces accumulation of water body causes that water body environment worsens, the lighter produces harmful effect to the growth of aquatic economic animal, growth, breeding; When serious, can cause epidemic disease to take place frequently and increase with the death rate, finally cause that aquatic product quality declines and output reduces.
Water purification mode in existing seawater intensive culture process is generally to 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 expensive shortcoming of high energy consumption; Although the water body for burst worsens, 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 has 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, and a kind of zeolite water purification agent of fast purification marine culture water is provided.
Technical scheme of the present invention is as follows:
According to the batching of the zeolite water purification agent of fast purification marine culture water, by zeolite (mass percent 80-90%) by micro-cut to help do mutually after technical finesse, micro-the cutting of zeolite obtaining more than 500-600 order helped powder, mixes input add water in fermentation vat and soak 12-24 hour with rice husk (mass percent 10-20%); By in the mixture input extruser after soaking, being uniformly mixed rear extruding is nearly spherical shape medicine ball, the diameter control of medicine ball is at 2-6 millimeter, being transported to dryer dries, after dry, the moisture of mixture is not higher than 10%, obtain, after required mixture medicine ball, being packaged as the finished product of the zeolite water purification agent of fast purification marine culture water.
Zeolite is the general name of zeolite family mineral, is the manosil AS mineral of a kind of moisture alkali metal or alkaline-earth metal.Zeolite structured by [SiO
4] and [AlO
4] tetrahedron take the mode on corner-sharing top to be unified into sial oxygen screen work be feature, wherein Si or Al are positioned at tetrahedral center, and respectively with oxygen bonding, oxygen is positioned at each summit of tetrahedron, forms many broad holes and duct in screen work.Because zeolite has unique internal structure and crystal chemistry character, thereby make zeolite have the multiple characteristic of utilizing for workers and peasants' fishery.
The absorption property of zeolite: natural zeolite has the large (440～1030m of specific area
2/ g), aperture is even, adds special molecular structure and forms larger electrostatic attraction, make zeolite there is sizable gravitational field, when the hole of zeolite inside and duct are once there be " vacancy ", zeolite will show very strong adsorption capacity, to SO in marine culture water
2, NH
3, H
2harmful polar gas molecule such as S has very strong affinity, and can efficient physical the harmful substance such as ammonia nitrogen in absorption breeding seawater and nitrite.
The ion-exchange performance of zeolite: the space structure elementary cell of zeolite is to be built into silicon (aluminium) oxygen tetrahedron by 4 oxygen atoms and 1 silicon or aluminium atomic reactor.At this tetrahedron; the valence link having in oxygen atom is neutralized; make whole aluminum-oxygen tetrahedron with negative electricity; for protection charge neutrality; the positive charge lacking carrys out compensation balance by near the cation of positively charged, these balance cations and hydrone very easily with ambient water solution in cation exchange, zeolite structured not being destroyed after exchange; the ion exchange property of zeolite, is beneficial to Hg in adsorption cleaning water

+, increase OH
-, avoid water acidification and the smelly end, guarantee the water body environment quality in sea-farming process.
Rice husk is one deck shell of paddy outside, by inner glume and larger coetonium composition.The long 5-10mm of rice husk, 2.5-5mm, thick 23-30 micron, it is golden yellow that its color and luster is generally, and after being pulverized, 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, can increase floatability, suspension and the sink-float controllability of product, be conducive to the clean-up effect of marine culture water 3 D stereo.
On existing market, marine culture water purifies preparation and mainly contains chemical reagent class and the large class of probiotics two, but ubiquity certain defects all.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 nonmetallic mineral, nontoxic, physical absorption, and efficient quick, inertia is strong, and cost is low, has the purifying water effect of efficient quick safety for acute water body pollution.
