A method for sludge dehydration and degradation

Abstract

The invention provides a sludge dehydration and degradation method. The sludge dehydration and degradation method comprises following steps: S1, sludge is delivered into a centrifugal machine so as to realize separation of liquid sewage and solid sludge in sludge, and solid sludge is delivered into a sludge dehydration temporary storage tank; S2, a heating plate in the sludge dehydration temporary storage tank is used for heating evaporation of water in the solid sludge, an auger conveyor is used for conveying obtained sludge into a tank; S3, an electronic on-ground weigher is used for weighing the sludge, and the sludge is delivered into a stirring drying device when sludge weigh reaches a preset value; S4, water in the sludge is removed further using the stirring drying device, and the sludge is subjected to gradual drying and degrading so as to obtain solid particles; and S5, waste gas in the stirring drying device is delivered into a waste gas dedusting unit for processing. The sludge dehydration and degradation method is capable of increasing sludge processing efficiency, processing tail gas, and reducing atmosphere pollution.

Description

technical field [0001] The invention relates to a method for dehydrating and degrading sludge, which can be applied to thick matter treatment, and is especially suitable for sludge treatment. Background technique [0002] Nowadays, with the rapid increase of my country's urban population and the development of social economy, the generation of urban sewage has increased sharply. While the amount of domestic sewage treatment has increased, the pressure on sludge treatment has followed. Moreover, the natural degradation of sludge takes a long time. The previous sludge is not degraded, and new sludge is piled up again, and the sludge will pollute the land and the surrounding environment. If things go on like this, it will cause serious damage to the ecological environment of the city. influence, thereby restricting the development of the city. The existing urban sewage treatment plants mainly use sludge reduction technology to reduce the volume of sludge, but the existing sludge...

[0002] Nowadays, with the rapid increase of my country's urban population and the development of social economy, the generation of urban sewage has increased sharply. While the amount of domestic sewage treatment has increased, the pressure on sludge treatment has followed. Moreover, the natural degradation of sludge takes a long time. The previous sludge is not degraded, and new sludge is piled up again, and the sludge will pollute the land and the surrounding environment. If things go on like this, it will cause serious damage to the ecological environment of the city. influence, thereby restricting the development of the city

The existing urban sewage treatment plants mainly use sludge reduction technology to reduce the volume of sludge, but the existing sludge treatment methods are inefficient and consume a lot of energy, that is, the cost is relatively high, and the existing sewage The mud treatment technology does not treat the exhaust gas, so the exhaust gas will pollute the environment
