The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements; it has strong adsorption properties and is a widely used industrial adsorbent. Activated carbon is a hydrophobic adsorbent made from carbon-based materials as raw materials, through high-temperature carbonization and activation; activated carbon contains a large number of micropores and has a huge specific surface area. It can effectively remove color and odor, and can remove most organic pollutants and certain inorganic substances in secondary effluent, including some toxic heavy metals; factors affecting activated carbon adsorption include: the characteristics of activated carbon; the characteristics and concentration of the adsorbate; the pH value of the wastewater; the suspended solids content and other characteristics; the contact system and operation mode; activated carbon adsorption is the most important and effective treatment technology in the advanced treatment of urban sewage, and has been widely used;

[0003] At present, there are many molds for making the appearance and shape of activated carbon particles. When using molds to prepare activated carbon particles, the following problems exist: a. From the time the activated carbon raw materials enter the mold to the molding and drying stage, there is no process of cleaning the surface of the mold, which makes the activated carbon raw materials on the surface of the mold stick more and more, which will not only cause waste of activated carbon raw materials, but also cause the surface of the mold to corrode due to some chemical substances contained in the activated carbon raw materials, shortening the service life of the mold; b. For the removal of the activated carbon particles die-cast in the mold, there are problems such as breakage, looseness, and deformation of the activated carbon particles, which requires these destroyed activated carbon particles to be re-die-cast, resulting in a decrease in the production efficiency of activated carbon particles and an increase in labor.

8. A novel activated carbon preparation process according to claim 1, characterized in that: The drying device (7) is provided with electric drying equipment and steam activation equipment.

9. A novel method for preparing activated carbon, applicable to the novel process for preparing activated carbon according to claims 1 to 8, characterized in that: The following steps are involved: S1. Material preparation and screening: The staff prepares corresponding coal powder and charcoal powder according to the needs and screens them through the vibration screening device (1) to ensure the consistency of particle diameter. The qualified carbon powder particles are respectively sent to the corresponding conveying and lifting devices (2) and can be output through the conveying and lifting devices (2) so as to store the carbon powder; S2, material storage and quantitative transportation: through the action of the transportation and lifting device (2), qualified carbon powder can be transported into the corresponding storage device (3), and at the same time, the electronic metering device (302) in the storage device (3) accurately measures the volume of carbon powder transported by the pipeline transportation device (303); S3, equipment cleaning and material mixing: the carbon powder is accurately transported into the stirring and mixing device (4) through the cooperation of the pipeline conveying device (303) and the electronic metering device (302), and the carbon powder can be fully mixed by the stirring and mixing device (4); S4, pressure forming and material discharge: The mixed carbon powder in the stirring and mixing device (4) is conveyed to the extrusion forming device (6) through the supply device (5), so that the carbon powder can be laid on (64), and at the same time, the lifting frame (6044) is driven by the electric telescopic component (605) to make the top rod (6043) descend, and the carbon powder will enter the conical groove (6042). The hydraulic cylinder device (601) makes the upper module (603) descend to squeeze the carbon powder in the conical groove (6042) down, and the carbon powder is condensed into blocks through high-pressure operation, and the electric telescopic component (605) can push the lifting frame (6044) to rise, so that the top rod (6043) pushes the activated carbon block out of the conical groove (6042) for easy collection; S5, carbonization and activation operation: the collected activated carbon blocks are placed in a drying device (7), the temperature is increased by an electric drying device in the drying device (7), a drying and carbonization operation is performed, and then an activation operation is performed by a steam activation device.
