Embodiment
[0029] Example: such as figure 1 , figure 2 and image 3 Shown, a kind of channel algae separation and biological fertilizer processing method, according to the following steps:
[0030] The first step: the algae salvaged from the river are rubbed with salt and rinsed to achieve the rehydration stage.
[0031] The second step: put the algae that has completed the rehydration stage into the algae separation furnace 3, and the initial water content of the algae in the algae separation furnace 3 is between the quality of the saturated steam delivered by the water vapor delivery pipe 9 and the moisture at the saturation point of the algae fiber and. Then, the algae in the algae separation furnace 3 is blasted by differential pressure, and supercritical carbon dioxide and water vapor are used to inject and pressurize together to complete the heating and pressurizing stage. In the heating and pressurizing stage, the supercritical carbon dioxide fluid pipe 8 and water vapor are f...

The invention relates to a river channel algae separation and biological fertilizer treatment method, which belongs to the technical field of algae recycling, and comprises the steps of rubbing and rinsing the salvaged algae from the river channel to realize the rehydration stage. Put the algae that has completed the rehydration stage into the algae separation furnace, and then use the differential pressure cell blasting process for the algae in the algae separation furnace, first use supercritical carbon dioxide and water vapor to inject and pressurize to complete the temperature increase and pressure stage, and then carry out The pressure holding process completes the cooking stage, and then the algae is separated and pretreated by instantaneous pressure release. After completing the differential pressure cell blasting process, the algae are then mechanically broken through the milling assembly. Then, the preparation process of bio-fertilization is completed by drying the heater. It has the characteristics of large processing capacity, high economic value, green environmental protection and strong sustainability. It solves the problem of river algae damaging the water body ecology. Improve the recyclability of algae and alleviate the accumulation of algae waste.
Description
technical field [0001] The invention relates to the technical field of algae recycling, in particular to a method for separating and treating algae in a river channel and turning them into biological fertilizers. Background technique [0002] Algae are embryoless, autotrophic, lower plants that reproduce by spores. Algae are unicellular, colony or multicellular body, the tiny ones can only be seen with a microscope, and the big ones such as sargassum and macroalgae can be several meters, tens of meters to hundreds of meters long. The internal structure begins to have cellular differentiation without real roots, stems, and leaves. The whole algal body is a simple frond containing chlorophyll capable of photosynthesis. The reproduction of algae is basically that single-cell spores or zygotes germinate into new individuals directly or after short-term dormancy after leaving the mother. [0003] Algae provide the basis for aquatic productivity by fixing inorganic carbon throu...
