Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a purifying agent for treating turtle breeding wastewater and a preparation method thereof, and a purification device for treating turtle breeding wastewater. Background technique [0002] my country's aquaculture industry has a long history, and its aquaculture output has ranked first in the world for many years, which has greatly met the people's growing demand for protein. At present, my country's aquaculture tends to be intensive, industrialized, high-density and high-yield aquaculture, and the average annual growth rate of aquatic products exceeds 10%. The nutritional composition of tortoise is similar to soft-shelled turtle, it is rich in protein, fat, carbohydrate, vitamins, trace elements and so on. The protein content of tortoise muscle reached 16.64%, essential amino acids and umami amino acids accounted for 49.16% and 43.39% of the total amino acids, respectively,...
