Problems solved by technology

[0004] However, the existing production process of bioflocs is complex, the reaction time is long, the release of nutrients is not complete and the loss of nutrients is serious, and noise, exhaust gas, and other pollutants will be generated during the process, causing secondary damage to the environment. Secondary pollution, and high energy consumption in the production process, resulting in high production costs, in view of this, we propose a production process of denitrification biofloc

Abstract

The invention discloses a production technology of denitrification type biofloc. The production technology comprises the following flow: step 1, preparing materials and weighing: selecting various agricultural organic wastes; after screening for a plurality of times to remove impurities, weighing and preparing the materials according to the ratio; step 2, carrying out pot filling: putting organicmatter raw materials obtained in step 1 into an enzymolysis and composting pot; carrying out sealing treatment on the enzymolysis and composting pot; keeping temperature in the enzymolysis and composting pot at a constant-temperature state and air pressure in the enzymolysis and composting pot at a constant-pressure state. According to the production technology disclosed by the invention, a constant-temperature and normal-pressure enzymolysis and hydrolysis technology is adopted and is efficient and specific; carbon-source monomer active nutrient elements can be released to the greatest extent; the production technology has the advantages of short reaction time, no generation of noises, waste gas and other pollutants; secondary pollution is not generated and nutrient components are protected to the greatest extent; the production technology does not need a complicated technological flow and has less energy consumption, so that the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the field of mortar, in particular to a production process of nitrogen-removing biological flocculation. 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 nearly d...
