Problems solved by technology

[0004] However, the preparation of existing bioflocs has the following disadvantages: one), the raw material processing technology for preparing the biofloc culture medium is complicated, and the production cost is relatively high; two), the nutrients released after the raw materials are technologically processed do not belong to The small molecular structure is difficult to dissolve in water, which makes it difficult to completely decompose in water. Over time, the raw materials will accumulate in the pond and form a secondary pollution situation. In view of this, we propose a production formula for denitrification biofloc

Abstract

The invention discloses a production formula of denitrified biofloc. The denitrified biofloc comprises 35% of beancurd skin powder, 25% of sucrose leftovers, 30% of wheat bran, 5% of medium trace element, catalyst and beneficial microbial bacteria. Agricultural organic waste is fully utilized, carbon source substances are recycled in aquaculture environment, and sustainable and comprehensive utilization of resources can be realized; raw materials are low in cost and easy to obtain, so that local materials can be used according to local conditions; nutritional substances released after the rawmaterials are technologized belong to micromolecular structure, are extremely soluble in water and different from other recycled products which can be decomposed thoroughly and accumulate in a pond after a long time, which causes secondary pollution; carbon source circulation of breeding water quality environment is facilitated, nitrogen in water body environment is facilitated to break away fromwater environment in a monomer state, no nonionic ammonia nitrogen and nitrite are formed, water quality environment is improved, and toxication of fishes and shrimps and damage to the same are avoided.

Description

technical field [0001] The invention relates to the field of water body cultivation, in particular to a production formula of denitrification type biofloc. Background technique [0002] Biofloc technology refers to adjusting the nutrient structure of the water body, using a variety of sugars to adjust the C / N ratio, and cooperating with probiotics to make the probiotics dominant in the shortest time, thereby inhibiting harmful bacteria. Probiotics degrade and transform nutrient waste such as residual bait and feces in the aquaculture system into nutrients that can be used by planktonic algae to reproduce, so as to achieve the purpose of fertilizer and water in disguise. By transforming nitrogen, phosphorus and other self-polluting substances into bacterial proteins, various extracellular products and metabolites are produced to provide prawns with a source of nutrients that can be re-uptaken, so that the utilization rate of nitrogen in the feed of aquaculture prawns is nearl...
