Environment-friendly water purifying agent for aquaculture and preparation method thereof

Abstract

The invention discloses an environment-friendly water purifying agent for aquaculture. The environment-friendly water purifying agent is prepared from the following raw materials in parts by weight: 34-36 parts of aluminum potassium sulfate dodecahydrate, 20-22 parts of polydimethyl diallyl ammonium chloride, 18-22 parts of polyacrylamide, 14-16 parts of attapulgite, 12-16 parts of fly ash, 10-12parts of activated charcoal, 9-11 parts of nano-silica, 9-11 parts of nano-silicon oxide, 7-9 parts of nano-titania, 6-8 parts of chitosan, 5-7 parts of disodium edetate, 3-5 parts of graphene oxide,2-4 parts of aluminum sulfate and 1-3 parts of polymerized ferric sulfate. According to the environment-friendly water purifying agent for the aquaculture, provided by the invention, the water purifying agent is environmentally friendly and efficient, meanwhile, is good in water purifying effect, cannot cause secondary pollution and has a relatively high use value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to an environment-friendly water purifier for aquaculture and a preparation method thereof. Background technique [0002] The water body is the environment that fish and shrimps and other aquatic animals must rely on for their survival and growth. The quality of water is the key to the success of aquaculture, especially intensive aquaculture. With the rapid development of aquaculture, water pollution is becoming more and more serious. It refers to the phenomenon that the water body is destroyed and the balance of water quality factors is out of balance due to factors such as human activities (production, life, etc.), secretions and excreta of the breeding objects themselves, excess bait, and drug residues; in recent years, my country's aquaculture industry has developed rapidly , the aquaculture scale continues to expand, but at present most of my country's aquaculture adopts ...

Problems solved by technology

[0002] The water body is the environment that fish and shrimps and other aquatic animals must rely on for their survival and growth. The quality of water is the key to the success of aquaculture, especially intensive aquaculture. With the rapid development of aquaculture, water pollution is becoming more and more serious. It refers to the phenomenon that the water body is destroyed and the balance of water quality factors is out of balance due to factors such as human activities (production, life, etc.), secretions and excreta of the breeding objects themselves, excess bait, and drug residues; in recent years, my country's aquaculture industry has developed rapidly , the aquaculture scale continues to expand, but at present most of my country's aquaculture adopts a high-density intensive aquaculture model, excessive stocking of seedlings, a large amount of fertilization and baiting make residual bait, aquatic organism excrement and corpses, sediments at the bottom of aquaculture water, Various organic and inorganic fertilizers and other eutrophication factors coexist in the same water body, and then abnormal changes occur, producing harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide, etc., causing disease or even death of aquaculture animals, and the discharge of industrial sewage and domestic sewage is undoubtedly Aggravated the pollution of aquaculture water, seriously restricted the sustainable development of my country's aquaculture industry

[0003] In the prior art, the decomposition of water purifiers used in aquaculture will cause secondary pollution, and the water purification effect is not very good, which limits the development of water purifiers in aquaculture technology
