The invention discloses a purification method for temporary culture process of shrimps, crabs and shellfish, which comprises three times of purification, wherein a bactericide is put in the first purification process for sterilization treatment; adjusting the water temperature, salinity and pH value in the second purification process, and continuously adding microalgae to remove most heavy metals; and removing residual heavy metals by using the composite protein metal chelating peptide in the third purification process. Realizes the sterilization and disinfection of the water body and the heavy metal removal, and effectively purifies the temporary culture environment of the shrimps, crabs and shellfish. Firstly putting microalgae to remove most heavy metals, and then removing residual heavy metals by utilizing the composite protein metal chelating peptide, so that the consumption of the composite protein metal chelating peptide can be saved, and the heavy metal removal rate is effectively improved. |
