The invention relates to the technical field of water treatment, provides a natural composite adsorbent and a preparation method and application thereof, and aims to solve the problem that a traditional biological adsorption material is low in mechanical strength and low in heavy metal removal rate. The natural composite adsorbent comprises, by weight, 10-20 parts of modified chitin, 20-40 parts of sodium alginate, 50-80 parts of biomass carbon materials, 30-45 parts of bentonite and 5-10 parts of microelement amino acid chelates. The natural composite adsorbent has the advantages that selected raw materials are green, environment-friendly, low in cost and high in mechanical strength, a gel factor is used to flexibly adjust and control dynamic balance of heavy metal adsorption, and the natural composite adsorbent is enabled to be high in adsorption rate. The preparation method of the natural composite adsorbent is simple, free from special requirements on equipment and easy for large-scale industrial production.
