Abstract

The invention provides a sludge aerobic fermentation device and relates to the technical field of sludge treatment. The device includes: a fermentation frame and a fermentation platform; shafts are arranged at both ends of the fermentation platform, and the shaft is connected to the fermentation frame through bearings; the shaft includes: a drive shaft and a ventilation shaft; the drive shaft is connected to a stepping motor, and the ventilation shaft passes through a sealed bearing It is connected with the fan; the upper and lower sides of the fermentation platform are equipped with fermentation tanks, and aeration pipes are arranged in the fermentation tanks. In the present invention, the sludge is poured into the top fermentation platform after mixing and pretreatment, and the fan supplies oxygen to the sludge through the aeration channel and the aeration pipe. °, the sludge is poured into the next layer of fermentation platform. During this process, the sludge originally located at the bottom layer is turned over to the top layer, and the heap is evenly supplied with oxygen, which further improves the oxygen aeration effect, reduces the generation of odor, shortens the fermentation cycle, and The organic matter in the sludge is converted into stable humus, and the obtained humus has excellent fertilizer quality.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge aerobic fermentation device. Background technique [0002] With the development of the domestic sewage treatment industry, the total treatment volume and treatment degree of sewage continue to increase, and the amount of sludge produced will also increase day by day. So far, the random dumping, stacking and irregular landfill of sludge have brought serious "secondary pollution" problems. Therefore, the treatment technology of urban sludge has become a "bottleneck" restricting the healthy development of my country's urban sewage treatment industry. Due to the different actual conditions at home and abroad, the sludge disposal methods have their own emphasis on the selected treatment methods. Sludge landfill needs to occupy a large amount of land, and there is a risk of leachate polluting surface water and groundwater systems. Land use is the recommended disposa...
