Problems solved by technology

If the stack is too large, an anaerobic zone is likely to be formed in the center, and odor will be generated when the stack is turned; if the stack is too small, the heat dissipation will be rapid, and it is difficult to guarantee the killing of pathogens and weed seeds
Fermentation tank fermentation is carried out in factory buildings or tunnel warehouses, which can be divided into two types: sunshine shed fermentation tanks and tunnel fermentation tanks. The commonly used fermentation processes generally have uneven mass transfer and long fermentation time; the system occupies a large area; Strong smell, difficult to collect and process

Abstract

The invention provides an aerobic ecological moving bed for biological drying, which comprises a tank body and a feeding device arranged at the upper part of the tank body and used for conveying sludge into the tank body; and an aeration device arranged in the tank body, arranged below the feeding device and having a height lower than the stacking height of sludge. The aeration device is used for conveying external air into the tank body, sludge is subjected to biological drying reaction under the action of oxygen, and the aeration device is also used for conveying generated water vapor to the outside of the tank body.

Description

technical field [0001] The invention relates to an aerobic ecological moving bed for biological drying, which belongs to the field of sludge treatment. Background technique [0002] With the continuous improvement of my country's sewage treatment rate and sewage treatment degree, the output of urban sludge is also increasing year by year. Municipal sludge is mainly composed of aerobic microorganisms, and also includes solid substances such as mud, sand, fibers, and animal and plant residues mixed into sewage, as well as adsorbed organic matter, heavy metals, germs, insect eggs and other substances. If a large amount of urban sludge is not properly disposed of, it will cause serious secondary pollution. [0003] Currently, sludge disposal methods mainly include landfill, land use, and incineration. Because municipal sludge usually has a high water content, it is still as high as about 80% after concentration and dehydration treatment, which has the characteristics of bulky,...
