The present application relates to the field of wastewater treatment, and specifically discloses a flocculating adsorbent for aquaculture wastewater and a preparation method thereof. A flocculation adsorbent for aquaculture wastewater includes a porous adsorbent material, and the porous adsorbent material includes: a porous matrix, in which a through-hole pore structure is formed; a degradation coating layer, at least a part of the degradation coating layer is provided on the surface of the porous matrix and/or the pore structure; the degradation coating layer comprises photocatalytic particles dispersed in the degradation coating layer. The preparation method includes: S1, grinding and dispersing, S2, coating liquid preparation, S3, coating modification. In this application, conventional porous materials are used to coat the degradable coating layer. The material contains photocatalytic materials, which can effectively carry out partial photocatalytic degradation of tetracycline and other harmful substances in aquaculture wastewater, so that the prepared flocculation material has a good degradation effect. . |
