Abstract
The invention discloses a meerschaum water purifying agent for quickly purifying a marine culture water body. The technical scheme is characterized in that the quick marine culture water purifying agent is mainly composed of meerschaum and rice hull. The water purifying agent is prepared through the following steps: performing PICT (pressure-shear induced chemical transitions) pulverization, soaking, stirring, extruding, drying, screening, and packaging to obtain the finished product. In the water purification and filtration process, the specific surface area of meerschaum is increased through a PICT technology, thus removing granular and colloid pollutants through adsorption, and effectively removing harmful substances such as key pollutants ammonia nitrogen, COD (chemical oxygen demand) and the like causing eutrophication of a water body. Big electrostatic attraction power and stress fields are formed outside the kieselguhr modified through the PICT technology, so that the ion-exchange property is enhanced, thereby being more beneficial to adsorptive purification of harmful substances such as Hg<2+>, Pb<2+>, Cr<6+>, Cd<2+>, Cu<2+>, other heavy metal ions and the like in the water. Thus, the meerschaum water purifying agent is applicable to purification and filtration such as quick ammonium reduction, nitrogen, phosphorus and COD removal, heavy metal adsorption and the like in the marine culture process, and is also applicable to purification of a marine aquarium fish water body.
Description
Technical field
The present invention, in aquaculture field, is specifically related to a kind of sepiolite 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 sepiolite 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 sepiolite water purification agent of fast purification marine culture water, by sepiolite (mass percent 80-90%) by micro-cut to help do mutually after technical finesse, micro-the cutting of sepiolite 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 sepiolite water purification agent of fast purification marine culture water.
Sepiolite is a kind of rich fibrous magnesium silicate clay mineral, has specific area maximum in nonmetallic mineral and (reaches as high as 800m
2/ g) and unique content pore passage structure, be the generally acknowledged the strongest clay mineral of adsorption capacity.Therefore have extremely strong adsorptivity, decolourising property, dispersiveness, heat endurance, good salt-resistance and cation exchange, be no matter that in brine, its structure does not all change under normal temperature or high temperature, condition of high voltage.
Because sepiolite has the characteristic that specific area is large, make it have powerful colloid absorption and ion-exchange absorption ability, in water treatment procedure, not only can adsorption particle state and the polluter of colloidal attitude, can also effectively reduce major pollutants ammonia nitrogen and the COD 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 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 385-400kg/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.
