The invention relates to method for enriching albumin from human urine on a large scale, which is especially suitable for large-scale application. The method is realized in a way that: a urine filter is made of an anion exchanger, is put in a urine bucket or a urinal and is used for containing urine, so that the urine can flow through the filter; the shape and size of the urine filter are suitable for those of the urine bucket or the urinal; the urine filter is regularly recovered, the anion exchanger in the urine filter is concentratedly desorbed, ingredients containing albumin are collected, and the anion exchanger is regenerated for later use; and after subsequent purification, the albumin the various indices of which meet the pharmacopoeia requirements can be prepared, and can be used as a substitute for human plasma source albumin in many fields.
