Description

A kind of water quality cleansing agent and preparation method thereof for aquaculture

Technical field

The present invention relates to a kind of water quality cleansing agent, specifically a kind of water quality cleansing agent and its preparation side for aquaculture Method.

Background technique

China is global first aquaculture big country, and status holds the balance in agriculture field, because of aquaculture face Product is big, and breeding water body pollution is also to have mesh to block up altogether, although water body has certain self-purification capacity, pursues high yield high density and supports It grows, the organic matters such as residual bait and excrement constantly accumulate, and often result in water body ammonia nitrogen, sulfide surges, and water hypoxia and richness occur Nutrient laden, this consequence are directly dead in addition to may cause cultivated animals, it is also possible to keep the phytoplankton being exponentially increased fast in short term Speed outburst, forms fierce ecologic competition, and leads to aquaculture organism severe depletion of oxygen indirectly and batch is dead, causes one to aquaculture Setting loss is lost.In order to improve cultivation water environment quality, ensures that breeding production is gone on smoothly, guarantee cultivation using Water body cleansing agent Water quality just seems especially necessary.

For the purified treatment of cultivation water, at present still without satisfactory medicament, traditional water in terms of chemicals treatment Body cleanser main component is adsorbent, is directly adsorbed to the impurity of water body, but cleaning effect is not thorough, clean-up effect compared with Difference；Water body is increased since chemical agent will affect water ecology using the usually used Water Treatment agent of sewage disposal system Other pollutional loads, it is larger to the negative effect after water body purification, and time consumption and energy consumption, hold time short；Using biological cleaning Preparation is often slow in the presence of decontamination speed, the bad defect of scavenging effect.

Summary of the invention

The present invention is in order to solve the problems, such as to provide a kind of water prepared with humic acid potassium and a variety of chelating agents in above-mentioned technology Matter cleanser solves the problems, such as purification of water quality in aquaculture, can effectively improve the water quality of breeding environment deterioration, builds one Be conducive to the breeding environment of water body animal growth.

The present invention provides a kind of water quality cleansing agents for aquaculture, as mass fraction, including 30%-50%'s Humic acid potassium, the bentonite of 20%-30%, the charcoal powder of 10%-20%, the calcium oxide of 5%-10%, the clay of 3%-10%, The aluminium polychloride of 1%-20%, the food grade polyacrylamide of 1%-20%.

The present invention also provides a kind of water quality cleansing agent preparation methods for aquaculture, comprising the following steps:

1) it takes weathered coal to be put into pulverizer, is crushed to the weathered coal powder that fineness is 100-120 mesh, food-grade hydrogen-oxygen is added It is put into reaction kettle extracting after changing potassium solution, takes supernatant to be pumped into centrifuge and is centrifuged, residue use is filtered out after slag-liquid separation In fertilizers for potted flowers and Nutrition Soil, the liquid filtered out is condensed into humic acid potassium stoste by thickener, and it is stand-by to be pumped into mixed preparing tank；

2) bentonite, charcoal powder, calcium oxide, clay are compounded in proportion and is put into pulverizer crushing, fineness after mixing evenly Reach 100-200 mesh, the preparing tank being sent into step 1) is stirred with humic acid potassium stoste, and mixed liquor is made；

3) mixture pump feeding spray dryer is dried to dry powder, dry powder is sent into dry powder blender by conveyer belt；

4) food grade polyacrylamide and aluminium polychloride is added toward dry powder blender in proportion, after being sufficiently mixed, passes through Conveyer belt is sent into pelleter, and powder piece is made；

5) powder piece is packed and stored by examining, sorting into packing machine.

Further, the dry powder moisture control in step 3) is in 10%-15%.

Compared with prior art, the present invention provides a kind of water quality cleansing agent prepared with humic acid potassium and a variety of chelating agents, It solves the problems, such as purification of water quality in aquaculture, can effectively improve the water quality of breeding environment deterioration, reduce in breeding process The breeding environment for being conducive to water body animal growth has been built in the secondary pollution for causing water body environment.

In addition, the potassium humate, bentonite, charcoal powder, polyacrylamide and aluminium polychloride in the present invention are net in water quality Play considerable effect in agent:

Humic acid potassium is a kind of complicated chelate, has stronger suction-operated to ammonia nitrogen, has organic point of flocculation Effect of son, can decompose the excreta of bottom cultivated animals, residual bait, organic floc sedimentation etc. in breeding water body, both reduce It is metabolized the stink of excrement, and increases the fertilizer efficiency of bottom grass algae because absorbing ammonia；It can also be by activating Pituitary Adrenal System promotes cortin and can simultaneously slow down the increase of capillary permeability caused by amine.In addition, humic acid potassium is macromolecule network Conjunction object is simultaneously containing alkaloids, has stronger adsorption capacity to enteric microorganism and noxious material, while viscous to cultivated animals enteron aisle Film has astriction and prevention enterogastritis effect；Humic acid potassium is compared with the antibiotic that the prior art uses, not only without toxicity And there are also detoxications, have detoxication to heavy metal, strychnia etc., and can reduce fertilizer urea toxicity in water body.

Several kinds of mineral elements contained in bentonite is that various metabolic processes and bone build institute not in animal body It can lack, adjusting can be played the role of, supplement microelement in aquaculture, fish and shrimp organism metabolism can be effectively facilitated, Disease resistance improves survival rate；And there is excellent absorption property, sulphion, the ammonium ion, heavy metal ion in water body can be made Deng concentration decline rapidly, can effectively stop the corruption of aquaculture pond bottom organic matter, so that the growing environment of aquaculture organism is always In good state, the yield of cultivation is improved.

Charcoal powder has very strong suction-operated, and has apparent deodorization functions, from a wealth of sources, quality-high and inexpensive, reduces The production cost of finished product.

Polyacrylamide and aluminium polychloride are gold partner in aquaculture, and the two collocation is a kind of efficient water Treatment agent, can make suspended matter, colloidal substance form wadding body, achieve the purpose that water purification by precipitating, to solve cultivation Production waste water cannot be discharged into municipal sewage plant, can not discharge in violation of regulations problem.

Specific embodiment

For a further understanding of the present invention, the preferred embodiment of the invention is described below with reference to embodiment, still It should be appreciated that these descriptions are only further explanation the features and advantages of the present invention, rather than to the claims in the present invention Limitation.

Embodiment one
