Application of Gasification Residue-based Activated Carbon in Coal Chemical Wastewater Treatment

The use of activated carbon to purify coal chemical wastewater is becoming more and more common. Converting gasification residues into activated carbon can also achieve recycling effects.

Activated carbon has a very important effect on activated carbon and mud. Heavy metals and other organic matter in the water are removed during the passage, and the water is cleaned properly, and it is possible to remove the fine quality of the water under the water.

In order to solve the problem of high pollution concentration in industrial wastewater, people have made full use of the adsorption characteristics of activated carbon and used activated carbon to adsorb organic substances in industrial wastewater. Activated coke in activated carbon is often used in shallow activation production work, using activated coke to purify flue gas and water. There are cavities inside activated carbon, but the pore sizes are generally small and numerous. It is an excellent adsorbent material and is often used in the treatment of chromium, cyanide, mercury, phenol, oil, etc. in industrial wastewater treatment. For example, when treating wastewater with high phenolic content, the wastewater is first introduced into hydrolysis acidification and secondary treatment.

Preliminary treatment is carried out in the main biochemical system such as the sedimentation tank, and the phenolic compounds are initially treated, and then the activated coke in the activated carbon is used to adsorb some of the remaining impurities, and then the remaining pollution is Continue to clean things up.

There are many methods for adding water soot to the furnace. However, during this process, there is no need to wash the tower in an extremely cold room, and the city uses a large amount of water, which comes from a large amount of water. However, a large scale soot production enterprise has decided to take the process to remove the water containing the residue, and the residue has been removed from the work, and the system has been created to convert the residue to other local processing. principle . However, since the agitation residue has been present since it contained a certain amount of moisture, the specific circumstances of the agitation during the course of the journey.

However, the circumstances of water extraction in the middle of the water removal process. Once a small amount of water falls on the road, as rain water flows into the ground water, the rain water system flows into the ground water, and the environment has been heavily contaminated since then, due to this demand.

It is necessary to change the structure in an effective manner and process the residue in the future. Due to the constant content of the residue in the atmosphere, the use of the land will be sufficient, the production of activated carbon will be possible, and the environment will be protected and the energy circulation will be utilized at the same time.
