The invention relates to a preparation method and application of strain immobilized particles for degrading enrofloxacin at low temperature. The immobilized particles are particles mainly prepared from strains, sodium alginate, sodium pyrophosphate, sodium hexametaphosphate, cane sugar, zeolite and biochar. The strain is alcaligenes, is named as Y-ENR, is preserved in the China General Microbiological Culture Collection Center (CGMCC) on September 7, 2022, the address is No. 3, No.1 yard, Beichen West Road, Chaoyang District, Beijing, the preservation number is CGMCC No. 25659, and the sequence of the strain is shown as SEQ ID No. 1. The effect of degrading enrofloxacin by the Y-ENR strain can be improved. The specific surface area is large, attachment and survival of microorganisms are facilitated, high strain activity is reserved, the mechanical strength is high, and the microbial agent can be put at any time and activated rapidly. The treatment temperature is reduced to 4-8 DEG C, and the method has huge e
