The invention relates to a method for preparing compound amino acid, which is characterized in that after a first barrier separation of lysine fermented liquor, threonine fermented liquor, glutamic acid fermented liquor and methionine fermented liquor, remaining strong liquor is mixed with mother liquor obtained after concentration and crystallization; pH value is regulated to 4-6; then the solution is evaporated and concentrated, sprayed with concrete and granulated; finished product can be obtained after sieved and dried. In the finished product, content of lysine is 50-60 percent, threonine 10-20 percent, glutamic acid 8-10 percent, and methionine 8-10 percent. The method for preparing compound amino acid prepares compound amino acid by mixing the remaining strong liquor from a first barrier separation of lysine fermented liquor, threonine fermented liquor, glutamic acid fermented liquor and methionine fermented liquor in current amino acid fermentation production with mother liquor obtained after concentration and crystallization, thus realizing a recycling of waste resource; simultaneously, the manufacturing process is simple; water and power can be saved without pollution; the production cycle is short; comprehensive cost is greatly lowered, which conforms to national energy-saving emission reduction policies.
