Aquaculture water purifying agent and preparation method thereof

Abstract

The invention discloses an aquaculture water purifying agent which 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 carboxymethyl cellulose, 10-15 parts of ferrate, 10-15 parts of potassium permanganate, 12-17 parts of potassium hydrogen persulfate composite salt and 5-8 parts of polyethylene glycol-6000. The water purifying agent can rapidly diffuse at a low level in a pool, can play a synergistic effect of physical purification and chemical purification, oxidizes and destroys heavy metalions, organic matters and other harmful substances, performs cage complexing, and provides oxygen for a water body at the same time.

Description

technical field [0001] The invention belongs to the field of water quality purification, in particular to an aquaculture water purifier and a preparation method thereof. Background technique [0002] China is a big aquaculture country. Because of the large area of ​​aquaculture, the pollution of aquaculture water is also purposeful. Research shows that in the current aquaculture process, due to the low utilization rate of bait, organic matter such as residual bait and feces continue to accumulate. Although the water body Has a certain self-purification ability, but pursues high-yield and high-density breeding, [0003] It often causes the surge of ammonia nitrogen and sulfide in the water body, hypoxia and eutrophication of the water body, and the enrichment of C, N, and P in the sediment and the reduction of redox potential, resulting in excessive ammonia nitrogen and nitrite content. It may lead to the direct death of farmed animals, causing the exponential growth of phyt...

AI Technical Summary

Problems solved by technology

Although the treatment effect of these chemical preparations is very good, they have limitations and pertinence: coagulants can only coagulate and have a long action period, flocculants can only flocculate, and the amount of oxidant has no effect, and excessive amount will cause phytotoxicity. Although there is no harm, but the amount used is large, and the oxygenating agent can only increase oxygen, etc.
