Biochar prepared from seawater shrimp culture solid waste as well as method and application thereof

The invention relates to the technical field of biochar, in particular to biochar prepared from seawater shrimp culture solid waste and a method and application of the biochar. The method specifically comprises the following steps: mixing seawater shrimp culture solid waste and shrimp shells of seawater shrimps according to a mass ratio of (2-4): 1, and carrying out lower-limit oxygen pyrolysis at 700-900 DEG C to obtain a substance, namely biochar (BC); or mixing the pyrolyzed products to obtain the biochar. The biochar obtained by the invention has better specific surface area and pore size, more pollutant adsorption sites and higher adsorption performance on water eutrophication pollutants, antibiotics such as enrofloxacin and the like. 本发明涉及生物炭技术领域，具体涉及一种利用海水虾养殖固废制备的生物炭及其方法和应用。具体为将海水虾养殖固废和海水虾的虾壳按质量比为2-4:1比例混合，混合后于700-900℃下限氧热解获得物质即为生物炭(BC)；或，所述热解后产物混合即为生物炭。本发明所得生物炭具有较优的比表面积、孔径体积，更多的污染物吸附位点，对水体富营养化污染物和恩诺沙星等抗生素的表现了较高的吸附性能。
