Abstract

The invention relates to the technical field of sewage treatment, and particularly relates to a nutritional complexing agent for aquaculture wastewater. The nutritional complexing agent for the aquaculture wastewater is characterized by being prepared from the following raw materials in parts by weight: 25-45 parts of sodium polyacrylate, 12-17 parts of oxalic acid, 15-20 parts of flour starch, 7-13 parts of coke powder, 6-9 parts of a ceramic ring, 20-25 parts of carboxymethyl cellulose, 7-9 parts of bacillus natto, 6-8 parts of actinomycetes, 8-11 parts of cellulase, 9-12 parts of triple bifidobacterium, 7-13 parts of green sulfur bacteria, 8-10 parts of bacillus subtilis, and 9-14 parts of indigenous bacteria. The nutritional complexing agent for the aquaculture wastewater involved in the invention has the advantages of high reaction efficiency, high speed and stable effect, and the reaction process is safe and non-toxic; meanwhile, no sludge treatment system is needed, and no secondary pollution is generated; the product is relatively low in cost and wide in application, and is suitable for promotion and use.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a nutritional compound agent for aquaculture wastewater. Background technique [0002] The scarcity of water resources is a global problem. Water is a non-renewable resource, but its importance to the maintenance of life on earth is self-evident. Therefore, in the reuse of water resources, sewage treatment is an important issue. Aquaculture wastewater is an important type of sewage. The main pollutants contained in the aquaculture wastewater are ammonia nitrogen, nitrite, organic pollutants, phosphorus and fouling organisms. At the same time, there are a lot of bacteria and suspended solids, and the color of general aquaculture wastewater is relatively dark. The treatment of aquaculture wastewater requires targeted treatment according to its characteristics. However, traditional physical methods and chemical agents often have the disadvantages of low efficiency and s...
