A sludge treatment equipment based on asphalt solidification technology

Abstract

The invention discloses sludge treatment equipment based on an asphalt solidification technology. The equipment comprises a wastewater tank; a primary sludge dewaterer is arranged on the upper side ofthe wastewater tank; the primary sludge dewaterer is used for removing water in sludge; a secondary sludge dewaterer is arranged on the right side of the primary sludge dewaterer; the secondary sludge dewaterer is used for carrying out secondary dewatering on the sludge; a moisture control device is arranged on the lower side of the primary sludge dewaterer; and the moisture control device can adjust the dehydration degree of the sludge secondary dehydration device on the sludge according to the initial moisture content of the sludge. Therefore, the stability of water content of dewatered sludge is ensured; a sludge solidification device is arranged on the right side of the secondary sludge dewaterer and used for mixing and stirring asphalt and sludge to solidify the sludge. Sludge with different water contents can be treated, the dewatering effect is stable, and industrial sludge dewatering and asphalt solidification integrated treatment is achieved.

Description

Technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge treatment equipment based on asphalt solidification technology. Background technique [0002] Sludge is a solid precipitate produced by the water and sewage treatment process. Industrial sludge refers to the sludge produced by industrial wastewater treatment stations. Generally, there are more inorganic sludges, which contain chemical components in production wastewater and belong to hazardous waste. Industrial sludge can be treated with asphalt solidification for harmless treatment. There are two types of asphalt solidification operations: one is to heat the asphalt and mix the waste, the other is to mix the emulsified asphalt with the waste, and the first method is to dry the waste to a certain extent. The present invention provides a device that can solve the above-mentioned problems. Summary of the invention [0003] Technical problem: There is currently a lack o...

Problems solved by technology

[0002] Sludge is a solid sedimentary substance produced in the process of water and sewage treatment. Industrial sludge refers to the sludge produced by industrial wastewater treatment stations. Generally, there are more inorganic sludge, which contains chemical components in production wastewater and belongs to hazardous waste. , Industrial sludge can be treated harmlessly with asphalt solidification. There are two kinds of asphalt solidification operations: one is to heat the asphalt and mix it with waste, and the other is to mix emulsified asphalt with waste. The first method has a certain drying effect on waste. At present, there is a lack of integrated treatment devices for industrial sludge dewatering and asphalt solidification. This invention clarifies a kind of equipment that can solve the above problems
