Problems solved by technology

However, due to the limited sources of protein, especially amino acids, the cost of traditional amino acid fertilizer and water preparations is relatively high. Using waste silk reeling protein to develop high-quality and low-cost amino acid fertilizer and water preparation products for fish ponds, it has the ...

Embodiment Construction

[0028] A method for using waste cocoon silk protein to manufacture amino acid fish pond fertilizer water preparation, comprising the following steps:

[0029] (1) Recovery of silk reeling waste silk protein: take the waste water from the reeling head, adjust the pH of the solution to the isoelectric point of sericin with hydrochloric acid, adjust the pH of the solution to 3.8-4.4 with hydrochloric acid, centrifuge for 30 minutes, remove the solution, and take The crude silk protein is obtained after the precipitation is concentrated in vacuo, soaked in a petroleum ether solution for 24 hours and degreasing, filtered, and the filtrate is taken and freeze-dried to obtain further purified crude silk protein.

[0030](2) Using waste cocoon and waste silk protein to prepare amino acids: take the crude silk protein obtained in step (1) and mix it with waste cocoon waste silk to obtain a mixture, hydrolyze the mixture with a 7% NaOH solution by mass, and add the mixture and NaOH solut...

Abstract

The invention relates to a method for manufacturing amino-acid fishpond fertilizer water aqua by waste bave protein. The method comprises the following steps of: preparing corresponding amino-acid hydrolysate by waste water, waste bave, waste silkworm pupae and the like of a reeling mill, and preparing the amino-acid fishpond fertilizer water aqua through the amino-acid hydrolysate, namely preparing amino-acid by hydrolyzing the bave protein, then adding urea, ammonium phosphate, potassium sulfate, ferric citrate, vitamin B1, vitamin B12, microbe consortium, trace elements and the like, and preparing the amino-acid fishpond fertilizer water aqua. According to the method, a brand-new way for reusing the reeling waste is developed, so that the cost and the pressure of the conventional sewage treatment method are reduced; and furthermore, the economic benefit of a factory and the yield of the factory are increased. The amino-acid fishpond fertilizer water aqua prepared by the method is low in cost, and has high quality and market competition. After the amino-acid fishpond fertilizer water aqua is added, the water quality can be improved effectively, so that the optimal growth environment is supplied to fishes.

Description

technical field [0001] The invention relates to a method for manufacturing a fish pond fertilizer water agent, in particular to a method for producing an amino acid fish pond fertilizer water agent by using waste cocoon silk protein. Background technique [0002] Guangxi is located in the subtropical zone, with a mild climate and abundant rainfall, which is very suitable for freshwater fish farming. Fish farming in ponds is the main body of Guangxi's freshwater fishery. Due to the limitation of geographical conditions, many places in my country rely entirely on or mostly rely on underground well water and natural river water for fish farming. The water quality of the fish pond is thin and it is directly used for raising fish, which is not conducive to the growth of fish. By applying chemical fertilizers or organic fertilizers, the water quality of fish ponds can be quickly fertilized. The invention patent application of Chinese Patent Application No. 2009103063302.0 discl...
