Problems solved by technology

The collection, salvage, drying and other processes of cyanobacteria have matured, but the further utilization of algae toxins is limited due to the presence of algae toxins in cyanobacteria. It is expected to be applied in feed, organic fertilizer and other fields, but the removal rate of algae toxins has defects such as poor stability, low removal efficiency, and high removal cost, and it is not suitable for application in feed, organic fertilizer and other food chain-related fields due to the principle of food chain transmission. Therefore, there is no relevant report on the research and application of industrial application products using blue-green algae as raw materials

Description

technical field [0001] The invention relates to the degradable field, in particular to a degradable carbonized material and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and industrialized production, the waste generated in industrial production and people's life has caused varying degrees of damage to the ecological environment, especially water pollution, which has seriously threatened the safety of people's normal drinking water, such as Persistent algal blooms. The collection, salvage, drying and other processes of cyanobacteria have matured, but the further utilization of algae toxins is limited due to the presence of algae toxins in cyanobacteria. It is expected to be applied in feed, organic fertilizer and other fields, but the removal rate of algae toxins has defects such as poor stability, low removal efficiency, and high removal cost, and it is not suitable for application in feed, organic fertilizer...
