Abstract
The invention relates to an aquaculture substrate modifier and a preparation method thereof and belongs to the technical field of aquaculture environment regulation and control. The aquaculture substrate modifier comprises the following components of 20-80 parts of activated sludge, 0.1-3 parts of chitosan and 1-10 parts of polyaluminum ferric chloride as adsorbents, 1-8 parts of calcium chloride as a calcium preparation and 10-60 parts of an excipient as the accessory. The preparation method comprises the following steps: the activated sludge is dried until the water content is below 20 percent, and all components are uniformly mixed to form particles ranging from 0.2 to 2cm. The substrate modifier for a biological pond has the advantages that raw materials are low-priced and easily obtained, and products are convenient for use; organic matters on the bottom of the pond can be quickly decomposed, the contents of toxic matters such as ammonia nitrogen, nitrite and the like are reduced, survival conditions of aquaculture objects are remarkably improved, and the diseases are reduced.
Description
Technical field
The present invention relates to the lasting low-cost bio type water bottom improving of environment input agent of a kind of breeding environment substrate modifier, particularly a kind of action time.
Background technology
Since entering 21 century, people more and more pay attention to food safety, particularly after " how precious fish " event, more and more stricter to the hygienic quality safety requirements of fishery products.For this reason, country is promoted to national standard veterinary drug operative norm by provincial standard, has forbidden many special efficacys but easy carcinogenic, poisoning pesticide and sterilizing agent, such as malachite green, Mercury protonitrate etc.On the other hand, people's living standard improves day by day, demand to fishery products constantly expands, but fishable resources is day by day exhausted, water surface for aquaculture is more and more by industrial land requisition, and consequently existing cultivation density increases year by year, and breeding environment constantly worsens, the probability of cultivation object morbidity increases, and cultivation risk increases.Culturist turns to method by improving breeding environment, balance breeding ecological to carry out the generation of pre-disease prevention, has reduced human body and the harmful sterilant of environment, the dependence of sterilizing agent.
In culture environment of aquatic products, bottom material of pond for breeding is very large on the impact of cultivating system.Pond bottom precipitation has accumulated the organism (residual bait, animal excrement, dead algae, zooplankton remains etc.) producing in a large amount of breeding process, makes the bottom oxygen consumption in pond more and more serious.Eubiosis cultural method is exactly the material cycle that promotes pond, and energy is flowed to animal proteinum direction, reduces objectionable impurities deposition.The use of substrate modifier aspect aquaculture is in recent years more and more, and some areas are used the expense of substrate modifier to account for the half cost except bait in input.Modifying agent for bottom material of pond for breeding mainly contains three kinds at present: a kind of is taking sorbent materials such as zeolite powder, Sodium salts humic acids, aluminium iron sulfate, polyacrylamides as main adsorptivity product, reach temporary transient obstruct organism oxygen consumption and discharge toxin with absorption bottom organism, but decomposition digestion of organic matter that can not be real; The second is taking mushrooms such as subtilis, bacillus natto, photosynthetic bacteriums as main biological substrate modifier, Decomposition by biological bacteria is decomposed bottom organism, shortcoming is that bottom is in anoxic condition, the survival rates such as the genus bacillus that capacity of decomposition is strong are not high, and very likely accelerate the anoxic of pond bottom.The third is taking the oxygenation agent such as SPC-D, calcium peroxide as main substrate modifier, and shortcoming is can only respite bottom anoxic condition, not strong to organic substance decomposing effect.Product of the present invention can reach that oxygen consumption is few, the effect of long-acting improving pond substrate, and the wide cost of main raw material(s) is low, and cost performance is high.
Summary of the invention
The active sludge that the present invention is rich in anaerobism and aerobic-anaerobic microbe by employing is main body, complex biological and chemosorbent, zymoexciter and auxiliary material etc., by techniques such as oven dry, stirring, granulations, granulation product, can directly drop into cultivating pool bottom, reach the organic object of efficient exploded bottom.
Summary of the invention
The present invention has adopted following several components to process:
Active sludge 20%-80%
Chitosan 0.1%-3%
Aluminium iron polychloride 1%-10%
Calcium chloride 1%-8%
Auxiliary material 10%-60%
The active sludge that the present invention adopts is mainly the by product of disposing of sewage and producing, and wherein adheres to multiple anaerobism and amphimicrobe, dries to water content below 20%.The part by weight of the shared product of active sludge is 20%-80%, and suitable proportion is 40%-70%, and optimum proportion is 60%-70%.There is following advantage with active sludge treatment water quality of aquaculture pond, substrate: 1, less demanding to dissolved oxygen,, compared with still can efficiently decomposing water body organic matter under low DO concentration, can realize weather dual-purpose, expand its use opportunity.2, cost is low.Because raw material is taken from the residual active sludge of sewage work, only need trucking costs, can greatly reduce production costs.3, active sludge anaerobion is indigenous bacterial classification, and activation rate is high, and bacterial classification is abundant, effect is comprehensive.Use anaerobic activated sludge to process behind pond, obviously raising of transparency, ammonia nitrogen and nitrite concentration significantly reduces, algae structure abundant.But the shortcoming existing is that the stink of anaerobic activated sludge is larger, has affected greatly production, storage and use etc.After composite and immobilization technology, can remove anaerobic activated sludge stink through the present invention, and easily use after granulation.
The effect in the present invention of chitosan and aluminium iron polychloride is sorbent material.Form organism micelle by the organic debris in sorbent material adsorbed water body, dead algae etc., be conducive to the decomposition of anaerobion.Although active sludge itself also has the effect of absorption and sedimentation organism and colloid thereof, input active mud content is less, and concentration is low, therefore a little less than adsorptive power.Chitosan has good synergy, Coagulation aiding to aluminium iron polychloride, and the growth that can be anaerobion provides carbon source, improves its activity.The adding proportion of chitosan and aluminium iron polychloride is respectively 0.1%-3% and 1%-10%, and ratio is 0.5%-2% and 5%-10% preferably, and best ratio is 0.5%-1% and 8%-10%.
The calcium chloride adding in the present invention can be the bulk of Calcium dichloride dihydrate, Calcium Chloride Powder Anhydrous, the raw material of granular or powdery, and with Calcium Chloride Powder Anhydrous the best of powdery, adding proportion is 1%-8%, preferably 3%-6%, and the best is 4%-5%.Calcium chloride can be used as siccative, makes up the deficiency that anaerobic activated sludge moisture is higher.Calcium ion can play the pH value effect of buffering microenvironment in addition, is conducive to the efficient decomposing organic matter of anaerobion.
The auxiliary material adding can be diatomite, zeolite powder, wilkinite etc., plays vehicle.Adding proportion is 10%-60%, preferably 20%-50%, and the best is 30%-40%.
Manufacture craft of the present invention is:
Get the capable oven dry of the abundant active sludge of anaerobion, moisture controlled, below 20%, then takes 20-80 parts of active sludge in proportion, 0.1-3 parts of chitosans, 1-10 parts of aluminium iron polychlorides, 1-8 parts, polymerization calcium chloride, 10-60 parts of auxiliary materials.After mixing, mechanical stirring 5 minutes, granulates after fully mixing, and after packaging, gets product.
