Graphite wastewater integrated treatment device

Abstract

The invention discloses a graphite wastewater integrated treatment device which comprises a treatment tank, wherein an annular shell is arranged on the outer wall of the treatment tank, the shell is provided with a water outlet hole communicated with the treatment tank, a main water inlet pipe is arranged at the top of the shell, a sealing plug is arranged at the lower end of the treatment tank, acolumn made of medical stone is inserted into the top of the sealing plug, the column is positioned in the treatment tank, the lower end of the sealing plug is connected with a conduit, the conduit is inserted into the column, the outside of the treatment tank is matched with a plurality of precipitation tanks, an overflow pipe is matched between the tops of two adjacent precipitation tanks, a first guide pipe is matched between one precipitation tank and the guide pipe, a pump body is matched on the first guide pipe, and the precipitation tank on the outermost side is connected with a dosingtank; the device can filter the graphite powder in the sewage and adjust the pH value of the waste water.

Description

technical field [0001] The invention relates to an integrated treatment equipment for graphite wastewater. Background technique [0002] my country's graphite reserves and annual output rank among the top in the world, and it is one of the world's major graphite suppliers. In recent years, the total annual output of graphite in China has reached more than 600,000 tons, of which the output of flake graphite has also reached more than 200,000 tons. With the development of my country's graphite deep processing technology With the development of the development, the output of graphite deep-processing products is increasing day by day, but the environmental pollution is also increasing. At present, there are more than 300 graphite production enterprises with a certain scale in my country. Except for a few factories and mines that use simple treatment processes to treat production wastewater, there is no formal The construction of industrial wastewater treatment projects and the env...

[0002] my country's graphite reserves and annual output rank among the top in the world, and it is one of the world's major graphite suppliers. In recent years, the total annual output of domestic graphite has reached more than 600,000 tons, of which the output of flake graphite has also reached more than 200,000 tons. With the development of my country's graphite deep processing technology With the development of the development, the output of graphite deep-processing products is increasing day by day, but the environmental pollution is also increasing. At present, there are more than 300 graphite production enterprises with a certain scale in my country. Except for a few factories and mines that use simple treatment processes to treat production wastewater, there is no formal The construction of industrial wastewater treatment projects and the environmental pollution caused by graphite production are mainly water pollution and atmospheric dust pollution, while water pollution is mainly reflected in the large amount of graphite residue produced by graphite production and a large amount of acidic substances in wastewater. The current graphite production wastewater The treatment devices are not yet mature, they are all reused after simple filtration treatment, the work efficiency is slow, and the wastewater treatment effect is poor
