Gongyi City Forté water purification materials into activated carbon coconut shell activated carbon, powdered activated carbon, activated carbon, shell activated carbon, granular activated carbon, coal granular activated carbon. The main raw material of carbon can be almost all carbon-rich organic material, such as coal, wood, shell, coconut, walnut shells, almond shells, shells and other dates. These activated carbonaceous material in a furnace at a high temperature and a certain pressure is converted to charcoal by pyrolysis. The main chemical properties of activated carbon indicators: PH value, ash content, moisture, fire point, not carbide, sulfide, chloride, cyanide, sulfate, acid substance, alcohol was the iron content, zinc content, lead content of arsenic , calcium and magnesium content, heavy metal content, and phosphates. The main charcoal adsorption performance indicators are: methylene blue adsorption, iodine adsorption, phenol adsorption, carbon tetrachloride adsorption, caramel adsorption, adsorption of quinine sulfate, saturated sulfur capacity, breakthrough sulfur capacity, water capacity , ethyl steam guard time, ABS values, etc. Due to the large activated carbon adsorption capacity of organic matter, get in wastewater treatment is widely used, has the following advantages: ① high degree of treatment, urban sewage treatment with activated carbon depth, BOD can reduced 99%, TOC can be reduced to 1 ~ 3mg / L. ② wide range of applications, the vast majority of organics in wastewater are valid, including microbial degradation of organic matter is difficult. ③ strong adaptability to changes in water and organic load of strong adaptability, stable treatment effect is obtained. ④ granular carbon can be reused reproduction, adsorbed organic compounds are burned in the regeneration process, does not produce sludge. ⑤ recyclable useful substances, for example, treatment with activated carbon wastewater, alkali regeneration of activated carbon adsorption saturated sodium salt can be recovered. ⑥ The equipment is compact, easy to manage.
