Sludge treatment device with deodorization function and method thereof

Abstract

The invention discloses a sludge treatment device with a deodorization function and a method thereof. The sludge treatment device comprises a first aerobic tank and a centrifugal dehydrator arranged on one side of the first aerobic tank; a second aerobic tank, wherein the second aerobic tank is arranged on the other side of the first aerobic tank, foam blocking plates are arranged in the first aerobic tank and the second aerobic tank; a foam collecting mechanism arranged on one side of the foam blocking plate, wherein a foam collecting frame driving seat is arranged at one end of each foam collecting mechanism, and a foam collecting frame is arranged at the other end of each foam collecting mechanism; and a foam scraping mechanism arranged between the blocking plate and the foam collecting mechanism, wherein the foam scraping mechanism comprises a foam baffle driving block, a foam scraping supporting frame, a foam scraping telescopic frame, a foam collecting frame sliding block, a foam scraping driving motor, a driving chain wheel, a driven chain wheel and a driving chain. The effect of scraping and cleaning foams generated during aerobic fermentation is realized, so that the problem that the effect of subsequent fermentation operation is influenced is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sludge treatment device and method with a deodorizing function. Background technique [0002] Sludge contains organic matter, heavy metals, pathogenic bacteria and other components. Its physical and chemical properties are very unstable. During the process of storage, transportation and treatment, the properties of its components will continue to change. If it is not handled properly, it will cause serious damage to the environment. harm. At present, domestic and foreign sludge disposal methods mainly include sludge incineration, sanitary landfill, and land use. Sludge incineration has low calorific value of sludge, and at the same time, it is difficult to remove the inner moisture of sludge, which affects the combustion stability. There is also the problem of how to meet environmental protection requirements for sludge incineration and its system, and the pri...

AI Technical Summary

Problems solved by technology

[0003] At present, the sludge treatment devices on the market often have floating foam on the surface during aerobic fermentation. During mechanical aeration, the foam isolates the air from contacting with water, reducing or even destroying the oxygenation capacity of the impeller; When the activated sludge is solid, it rushes to the secondary settling tank for sedimentation efficiency and deteriorates the water quality. Therefore, it is necessary to clean the foam at this time. However, the aerobic tanks currently on the market are not cleaned thoroughly, which affects the effect of subsequent fermentation operations.
