Problems solved by technology

[0003] The existing industrial sludge is the sludge produced by the industrial wastewater treatment station. It is the sludge produced by the treatment methods such as dilution and mixing during the harmless treatment of industrial wastewater by the industrial wastewater treatment station. Generally, there are more inorganic sludge. It belongs to medium and fine-grained mixed sludge, which has good dehydration performance of fibrous body, and the other compressibility and dehydration performance are average, and contains chemical components in production wastewater, which belongs to hazardous waste. In the process of industrial sludge treatment, It is necessary to choose the appropriate dehydration method according to the nature of the wastewater. In addition, it is necessary to choose specific follow-up treatment methods such as landfill or incineration according to the composition of the dehydrated sludge, and this follow-up treatment method will also cause damage to the environment. Landfill The treatment method will cause erosion and pollution to the soil at the sludge landfill, which will deteriorate the soil quality near the landfill, and will also affect the nearby groundwater. The incineration treatment method is easy to cause damage to the atmospheric environment, and auxiliary combustion is required Raw material, higher cost

Abstract

The invention discloses an environment-friendly waste heat treatment device for oxidation treatment of sludge and a method for using the same, belonging to the technical field of sludge treatment. An environment-friendly waste heat treatment device for oxidation treatment of sludge comprises a sludge waste heat mixing tank, a sludge The right end of the waste heat mixing kettle is fixedly connected with a motor, and the right end of the sludge waste heat mixing kettle is dug with a force through hole, which can realize the use of a special structure in the sludge heating and drying stage, using the waste heat of industrial sludge to disperse and mix in industrial sludge, stirring device The sludge is stirred and dehydrated. At the same time, the sludge mixing and stirring rod rotated by the stirring device can accelerate the rupture of the arc-shaped capsule, so that the substances in the arc-shaped capsule can neutralize the heavy metal ions in the industrial sludge, and at the same time, the industrial The microorganisms in the sludge are killed to reduce the environmental damage caused by the pollutants in the industrial sludge, which not only realizes the treatment of industrial sludge, but also enables the sludge to be used as plant fertilizer for secondary use.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, and more specifically relates to an environment-friendly waste heat treatment device for oxidation treatment of sludge and a method for using the same. Background technique [0002] Sludge treatment refers to the process of reducing, stabilizing and harmless sludge such as concentration, tempering, dehydration, stabilization, drying or incineration. Sludge treatment is to reduce and stabilize sludge The process of chemical and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complicated and costly part of the operation of the sewage treatment system. Sludge is compo...
