Description
Technical Field
The invention belongs to the field of water purification, and particularly relates to an aquaculture water purifying agent and a preparation method thereof.
Background
China is a big aquaculture country, because the aquaculture area is large, the pollution of aquaculture water is also blocked, researches show that in the current aquaculture process, because the bait utilization rate is low, organic matters such as residual bait, excrement and the like are accumulated continuously, although the water has certain self-cleaning capacity, high-yield and high-density aquaculture is pursued,
the ammonia nitrogen and sulfide in the water body are increased suddenly, the water body is anoxic and eutrophicated, and the C, N, P enrichment and the oxidation-reduction potential of the bottom mud are reduced, so that the content of the ammonia nitrogen and the nitrite exceeds the standard, and the cultured animals can die directly, so that the exponentially growing phytoplankton can rapidly burst in a short period to form strong ecological competition, and the cultured organisms are seriously anoxic and die in batches, thereby causing certain loss to the aquaculture industry; the discharge of a large amount of breeding wastewater causes great influence on the surrounding environment, the water area environment is deteriorated, red tide frequently occurs, and the ecological balance and the biodiversity are damaged. In order to improve the quality of the aquaculture water environment and ensure the smooth operation of aquaculture production, the water purifying agent is especially necessary to ensure the aquaculture water quality.
At present, the prior art for treating polluted water at home and abroad can be divided into a chemical method, a physical method and a biological method. However, although the existing methods can purify the water body to a certain extent, the existing methods have respective disadvantages.
The chemical method generally comprises the steps of using various halogen element preparations, surfactants, chlorine dioxide and other chemical preparations to realize the disinfection of the water body and the improvement of the water quality, wherein the products can generate secondary pollution in the using process, increase the viscosity of the water body, cause the hardening of the bottom of the water body, are not beneficial to even the establishment of ecological balance of the water body, and cause damage to water body organisms, animals and people in the food chain.
The physical method generally uses macromolecular and polar chemicals and minerals (such as zeolite powder) containing a large number of micropores for complexing adsorption, and harmful substances are precipitated at the bottom of the water body to achieve the temporary water body purification target; however, basically, harmful substances are not degraded, but are concentrated and covered at the bottom, and are diffused into the water again along with the change of the water conditions at any time, so that more serious problems are caused.
Despite the physical breakthrough of aquaculture water treatment in recent years, the treatment still has great defects in chemical preparations. At present, the water treatment aspect of China is still used: coagulants such as potassium ferrate, polyaluminium chloride, polyferric sulfate, nonionic polyacrylamide and cationic polyacrylamide, oxidizers and adsorbents such as activated carbon, bromochlorohydantoin, zeolite powder and diatomite, and oxidizers such as sodium percarbonate and potassium persulfate. These chemicals, while very effective in treatment, have limitations and pertinence: the coagulant can only be coagulated, the action period is long, the flocculant can only be flocculated, the oxidant dose is small, the effect is not good, the dose is large, the pesticide harm is caused, the adsorbent does not have the pesticide harm, but the dose is large, and the oxygen increasing agent can only increase oxygen and the like.
Under the background, the water quality purifying agent is provided, can play a synergistic role of physical purification and chemical purification, and has important application significance.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide an aquaculture water purifying agent which can be quickly diffused in a pond in a low degree, can play the synergistic action of physical purification and chemical purification, oxidizes and destroys heavy metal ions, organic matters and other harmful substances, carries out cage type complexation and simultaneously provides oxygen for a water body.
The invention is realized by the following technical scheme:
an aquaculture water purifying agent is prepared from the following raw materials in parts by weight: 20-30 parts of nano calcium carbonate, 15-20 parts of attapulgite, 15-20 parts of sodium carboxymethylcellulose, 10-15 parts of ferrate, 10-15 parts of potassium permanganate, 12-17 parts of potassium hydrogen persulfate composite salt and 8-05 parts of polyethylene glycol-600.
The invention further improves the scheme as follows:
an aquaculture water purifying agent is prepared from the following raw materials in parts by weight: 22-28 parts of nano calcium carbonate, 17-19 parts of attapulgite, 17-19 parts of sodium carboxymethylcellulose, 12-15 parts of ferrate, 12-15 parts of potassium permanganate, 14-16 parts of potassium hydrogen persulfate composite salt and 8-6 parts of polyethylene glycol-60006.
The invention further improves the scheme as follows:
an aquaculture water purifying agent is prepared from the following raw materials in parts by weight: 25 parts of nano calcium carbonate, 18 parts of attapulgite, 18 parts of sodium carboxymethylcellulose, 13 parts of ferrate, 14 parts of potassium permanganate, 15 parts of potassium hydrogen persulfate composite salt and 60007 parts of polyethylene glycol.
The invention has the further improvement scheme that:
weighing the raw materials according to the weight parts, sequentially adding the raw materials into a mixing machine according to the sequence of ferrate, nano calcium carbonate, potassium permanganate, attapulgite, potassium hydrogen persulfate composite salt, sodium carboxymethylcellulose and polyethylene glycol-6000, uniformly stirring one raw material, adding the next raw material, stirring for 10-20 minutes after all the raw materials are added, and preparing into granules or tablets by using a granulator or a tablet machine under the environment of 10-30 ℃ and relative humidity of less than 50%.
The invention has the beneficial effects that:
the ferrate used in the present invention has ferrate as its active component and is very oxidizing and thus can be disinfected through oxidation. Meanwhile, the reduction product after the reaction is ferric hydroxide which is colloidal in the solution, so that suspended matters in water can be gathered to form precipitate, and fine suspended matters in water can be efficiently removed. Namely: the ferrate has the water purification effect of chlorine and alum.
The potassium permanganate used in the invention releases nascent oxygen and manganese dioxide when meeting water, and no free oxygen molecules are released, so no bubbles appear. The nascent oxygen has the functions of sterilization, deodorization and detoxification, and the potassium permanganate has stronger and longer-lasting antibacterial and deodorization function than the hydrogen peroxide solution. Manganese dioxide combines with protein to form a gray-black complex ("palm manganese") which exhibits astringent properties at low concentrations and irritant and corrosive properties at high concentrations. The bactericidal power is enhanced along with the increase of the concentration, 0.1 percent of the bactericidal power can kill propagules of most bacteria, and 2 to 5 percent of the solution can kill the bacteria within 24 hours. The bactericidal effect can be obviously improved under the acidic condition, for example, 1.1 percent hydrochloric acid is added into 1 percent solution, and anthrax spores can be killed within 30 seconds.
The active substance of the potassium hydrogen persulfate composite salt used in the invention is potassium hydrogen persulfate. Has very strong and effective non-chlorine oxidation capability, and the using and processing process meets the requirements of safety and environmental protection.
The water purifying agent for aquaculture disclosed by the invention has the beneficial effects that the used raw materials are nontoxic, low in corrosivity and free of pungent smell, the water purifying agent is safe and environment-friendly to use, has higher water purifying efficiency and effect, and is suitable for being generally popularized and used.
The attapulgite used by the invention has larger specific surface area, good adsorption effect, deodorization and odor removal, heavy metal ion removal and adsorption and sedimentation effect on floccules in water.
