Abstract

This invention discloses a method for producing concavo-convex rod(CCR) granule absorption and oxygen-increasing agent. It is composed of: CCR stone clay, natural mineral absorption agent, sodium percarbonate, quick lime and ferrous sulfate. The production steps are: the raw materials are mixed and then pulverized, pressed into pellets, packaged to obtain the finished products. This inventive products, after distributed in pond, can increase the dissolved oxygen (DO), to moderate or eliminate the oxygen deficient in the pond for culturing fish, shrimp, crab or other aquatic animals. It can also absorb ammonia nitrogen, hydrogen sulfide and other toxic matter, and regulate the pH value in water. This inventive product can be produced in shapes of: balls, pellets, blocks, cylinders or other shape.

Description

Technical field: [0001] The invention relates to an oxygen-increasing agent, in particular to a production method for absorbing an oxygen-increasing agent by attapulgite particles. Background technique: [0002] The main source of ammonia nitrogen in aquaculture is the feed that sinks to the bottom of the pond, fish excrement, fertilizer, and the remains of dead animals and plants. About 80% to 90% of the nitrogen-containing excrement of fish is ammonia nitrogen; The ammonia nitrogen produced by the decomposition of feces and feed residues cannot be completely absorbed by phytoplankton, resulting in excessive ammonia nitrogen and nitrite in the water body, which can inhibit the growth of fish and cause fish death in severe cases, thus affecting the overall quality and output of aquaculture . [0003] In the process of aquaculture, the traditional oxygenation method can no longer meet the needs of the aquaculture industry. The powerful oxygenation machine is easy to injure f...
