Abstract

The invention relates to a sludge high-temperature aerobic composting treatment method. The treatment method comprises the following steps: (1) conveying dewatered sludge of a plate-and-frame filter press to a sludge deep treatment workshop, mixing the dewatered sludge with a strain fermentation material, and stacking the mixture in an aerobic fermentation tank of the sludge deep treatment workshop; (2) performing ventilating aeration by an aerator pipe at the bottom in the aerobic fermentation tank to ferment the mixture of the dewatered sludge and the strain fermentation material, turning over the mixture during the fermentation process, and transporting the mixture outwards after the mixture is fermented to be mature. The sludge high-temperature aerobic composting treatment method is simple in steps.

Description

technical field [0001] The invention relates to a sludge high-temperature aerobic composting treatment method. Background technique [0002] During the sewage treatment process, the residual sludge of the sewage plant is processed into compost for secondary treatment. The sludge compost produced by the traditional treatment method has a high moisture content, a foul smell, and the steps are cumbersome and complicated. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a sludge high-temperature aerobic composting method, which is simple and convenient to operate. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a high-temperature aerobic composting treatment method for sludge, the treatment method comprising the following steps: (1) transporting the dewatered sludge from the plate and frame filter press to the s...
