Embodiment

[0021] The commercially available cylindrical bamboo charcoal is crushed to form a semi-cylindrical bamboo charcoal, and then the dewatered sludge and bamboo charcoal layers are laid alternately inside the fermentation tank to ensure that a layer of bamboo charcoal is arranged at the bottom vent of the fermentation tank. The layer is made up of multiple horizontal semi-cylindrical bamboo charcoal layers with openings downwards. The thickness of each layer of dewatered sludge is 2-3cm. Then the laid bamboo charcoal layer and dewatered sludge are subjected to aerobic fermentation. The ventilation rate is 1m 3 / min, the fermentation period is 28d.

Abstract

The invention discloses a multilayer aerobic fermentation system and a fermentation method thereof, and belongs to the technical field of aerobic composting. The technical scheme is characterized in that the multilayer aerobic fermentation system comprises a fermentation tank, wherein sludge layers and bamboo charcoal layers are alternately arranged inside the fermentation tank from top to bottom, the bottom layer is the bamboo charcoal layer, the bamboo charcoal layer is formed by horizontally arranging a plurality of semi-cylindrical bamboo charcoal with a downwardly opening in a single layer manner, and the upper portion and the lower portion of the fermentation tank are respectively provided with a gas inlet and a gas outlet. The invention further specifically discloses the fermentation method of the multilayer aerobic fermentation system. According to the present invention, the used separation material bamboo charcoal can reduce the ammonia volatilization and reduce the total nitrogen loss, and has the porous structure compared to the traditional conditioner wood chips so as to effectively adsorb the odor generated during the fermentation process, the composition of the fermentation substrate is simple, the condition that the substrate contains a large number of the difficultly-degraded materials due to the addition of wood chips and other conditioners is avoided, and the fermentation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of aerobic composting, and in particular relates to a multi-layer aerobic fermentation system and a fermentation method thereof. Background technique [0002] With the development of urbanization in my country, the discharge of urban domestic sewage continues to increase, and the number of sewage treatment facilities also continues to increase. The accompanying dewatered sludge produced in the sewage treatment process has become a new environmental problem. Therefore, the recycling of urban domestic sewage sludge has become a new environmental research hotspot. [0003] Among the numerous sludge recycling methods, the sludge aerobic fermentation method is favored for its advantages of low infrastructure investment and operating costs, high degree of sludge stabilization and harmlessness, convenient operation, and the fermented products can be used in agriculture. people's attention. However, during the rea...
