Problems solved by technology

These two methods are suitable for dealing with large-scale outbreaks of cyanobacteria, but their biogas and fertilizer products have a long production cycle and low added value. Improper treatment is likely to cause secondary pollution, and the economic benefits are barely equal to the treatment cost, which is currently difficult to market root cause of promotion

Abstract

The invention relates to a device special for biological fertilizer made of blue-green algae, reeds and straw. An inlet of a blue-green algae dewatering machine is connected with a blue-green algae temporary storage pool through a conveying pipeline. A straw smashing machine is arranged parallel to the blue-green algae dewatering machine. The straw smashing machine and a discharging port of the blue-green algae dewatering machine are connected with a feeding port of a fermentation roller through a feed mechanism. A discharging port of the fermentation roller is connected with a dryer. A waste gas outlet of the dryer is connected with a dust falling device through an air pipe. An induced draft fan is arranged at the outlet of the dust falling device, and the dust falling device is connected with a tail gas washing device through the induced draft fan. A discharging port of the dryer is connected with a finished product packaging platform through a cooling and heat dissipating material conveying mechanism. The device is reasonable in structural design and high in automation degree, labor and time are saved, manpower can be greatly saved, the production efficiency can be improved, 4-5 days needed by an original landfill method process are shortened into one day, operation is easy and convenient, and the device is very suitable for requirements of bio-organic fertilizer production.

Description

technical field [0001] The invention relates to a special device for making fertilizer by using blue-green algae, reeds and straws, and belongs to the technical field of waste resource utilization. Background technique [0002] The eutrophication of lakes, reservoirs and other water bodies results in the proliferation of algae and the formation of blue-green algae. When cyanobacteria blooms break out, the water surface is covered by a thick layer of blue-green indigo, which migrates to the shore and accumulates with the wind direction, and emits an unpleasant smell after decay. On the one hand, large-scale cyanobacteria outbreaks inhibit the growth and reproduction of other algae in water bodies, reduce algae species, reduce biodiversity, and then destroy the balance of the ecosystem. On the other hand, it has caused the deterioration of water quality in lakes, reservoirs and other water bodies, manifested as black and smelly water quality and decreased dissolved oxygen. T...
