Description

Technical Field

[0001] The present application relates to the field of sludge fermentation, and in particular, to a fabric structure and a sludge fermentation tank. Background Art

[0002] The sedimentation tanks of municipal and domestic sewage treatment plants will produce a large amount of activated sludge, which contains a large amount of organic matter and microbial communities and is often used to make organic fertilizer. During the production process, it needs to be fermented in a fermentation workshop. The spreading machine is a device that evenly spreads the treated sludge in the fermentation tank. It runs on the track beside the fermentation tank through the running wheels driven by a motor to complete the spreading of the sludge. However, the existing spreading machine does not have the function of adding bacterial agents. The additionally added fermentation biological bacteria need to be mixed with the sludge to be fermented in the stirring equipment. Due to the huge amount of sludge, a separate large-scale stirring and mixing equipment is required, which requires a large investment. In addition, the existing spreading machine has insufficient stirring effect on the sludge in the fermentation tank during movement, which is not conducive to the aerobic fermentation of the sludge.
