Preparation for strongly removing vibrios and preparing method of preparation

The invention relates to the technical field related to elimination of thalli, and particularly provides a preparation for strongly eliminating vibrios and a preparing method of the preparation. On one hand, provided is the preparation for strongly removing vibrios, wherein the preparation comprises the components in percentage by weight: 65-85% of a first guanidine derivative, 2-12% of a second guanidine derivative and the balance being ethanol, wherein the first guanidine derivative is polyhexamethylene guanidine salt and/or polyhexamethylene biguanide salt; and the relative molecular weightof the second guanidine derivative is 500-1500. The vibrios can be effectively removed by utilizing polyhexamethylene guanidine hydrochloride and chlorhexidine hydrochloride under the specific content. The preparation provided by the invention has a strong removal effect on pathogenic vibrios, such as vibrio parahaemolyticus, vibrio anguillarum, vibrio alginolyticus, vibrio cholerae, vibrio fluorescens and the like, has
