The invention relates to a method for separating algae in a river channel and treating it as a biological fertilizer, and belongs to the technical field of algae reuse, which includes rubbing and rinsing the algae salvaged from the river channel to achieve a rehydration stage. The algae that have completed the rehydration stage are put into the algae separation furnace, and then the pressure difference cell blasting process is applied to the algae in the algae separation furnace. First, the supercritical carbon dioxide and water vapor are co-injected and pressurized to complete the heating and pressurizing stage. The pressure-holding process completes the cooking stage, and then the algae are separated and pre-processed by instantaneous pressure relief. After the blasting process of differential pressure cells is completed, the algae go through the grinding component for mechanical crushing process. Then, the preparation process of biological fertilizer is completed by drying the heater. It has the characteristics of large processing capacity, high economic value, green environmental protection and strong sustainability. Solve the problem of river algae damage to water ecology. Improve the renewable utilization of algae and ease the accumulation of algae waste. |
