Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and in particular relates to a sludge composting aeration device. Background Art

[0002] Sludge is the product of sludge treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content, high organic content, easy to decompose and stink, and fine particles, small specific gravity, and colloidal liquid. It is a thick substance between liquid and solid and can be transported by pumps, but it is difficult to separate solids and liquids by sedimentation. In the process of sludge treatment, it needs to go through a variety of treatment steps, including the process step of aeration. Aeration is to force air into the sludge to strengthen the contact between the organic matter in the sludge and the microorganisms and dissolved oxygen to ensure the oxidation of the organic matter in the sludge by the microorganisms.

[0003] Most existing aeration devices are fixed at the bottom of the tank. When the aerator of the aeration device fails after long-term use, all the sludge in the tank needs to be drained during maintenance. The aerator can only be repaired and replaced after the aeration device stops running, which seriously affects the aeration treatment process and reduces the aeration treatment efficiency.
