Abstract

The invention discloses a fermentation system and fermentation method of a carbon-based fertilizer. The fermentation system comprises a material mixing unit for receiving materials and mixing the materials, and a material fermentation unit for fermenting the mixed material, and further comprises a material pyrolysis unit for performing pyrolysis carbonization on partial completely fermented material so as to generate charcoal; the material mixing unit receives the charcoal generated by the material pyhrolysis unit and mixing the charcoal with other received material. A technical problem solvedby the invention is to solve the problem that partial anaerobic situation exists and the fertilizer water is easy to loss in the produced charcoal fertilizer since the conventional aerobic sludge fermentation is easy to cake, and the invention provides the fermentation system and the fermentation method of the carbon-based fertilizer capable of improving the filling power of the sludge and enabling the carbon-based fertilizer to retain fertilizer and eater.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment in the environmental protection industry, in particular to a carbon-based fertilizer fermentation system and a fermentation method. Background technique

[0002] Sludge is one of the main by-products of urban sewage treatment plants. With the development of urbanization and the improvement of environmental protection requirements, the output of sludge has increased dramatically. Sludge contains a large number of germs, parasites and harmful substances (such as heavy metals) and is often accompanied by odor. Arbitrary stacking or improper handling may cause secondary pollution. In addition, in addition to the above-mentioned substances, sludge also contains a large amount of organic matter, which will be wasted if arbitrarily piled up and disposed of. Fermentation and composting of sludge is an important way to utilize sludge.

[0003] The problem existing in the existing aerobic ferment...
