Water purifying agent for aquaculture, and preparation method thereof

Abstract

The invention discloses a water purifying agent for aquaculture, and a preparation method thereof. The water purifying agent comprises, by weight, 50-60 parts of tourmaline particles, 30-50 parts of modified zeolite, 20-30 parts of polyaluminum chloride, 15-25 parts of potassium ferrate, 10-20 parts of copper sulfate, 3-8 parts of carbon black, 10-30 parts of activated carbon fibers, 2-8 parts of diatomaceous earth, 3-8 parts of calcium oxide and 1-5 parts of magnesium oxide. The preparation method comprises the following steps: crushing and uniformly mixing the tourmaline particles, modified zeolite, polyaluminum chloride, potassium ferrate, copper sulfate, carbon black, activated carbon fibers, diatomaceous earth, calcium oxide and magnesium oxide to obtain a powder, and drying the powder to produce the water purifying agent for aquaculture. The water purifying agent for aquaculture has the advantages of physical purification and chemical preparation synergism, obvious coagulation effect, and fastness and thoroughness in purification, and is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of purifiers, in particular to an aquaculture water purifier and a preparation method thereof. Background technique [0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country. Its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. However, my country's current aquaculture industry is in a transition from the traditional high-yield sheep herding model to the large-scale However, since my country's aquaculture still adopts the method of large-scale introduction and large-scale discharge, it not only consumes a lot of water resources, but also feed residues and fish, shrimp, and crabs put in during the aquaculture process The pollutants formed by excreta pollute the water body and pond bottom mud, making the aquaculture water body increasingly eutrophic, and causing more and more harm to the surrounding water environment and ecol...

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 to the medicine, but the amount used is large, the oxygen enhancer can only increase oxygen, etc. In this context, a new multi-functional composite new water quality purifier that can improve the declining water quality becomes of great significance
