    The activated carbon products have good adsorption performance for phenol in the treatment of wastewater containing phenol. The increase of temperature is not conducive to the adsorption, and the adsorption capacity decreases; but the time to reach the adsorption equilibrium by increasing the temperature is shortened. wood activated carbon powder The results showed that the amount of activated carbon and adsorption time had the best value, and the removal rate changed little under the acidic and neutral conditions; under the strong alkaline condition, the phenol removal rate decreased sharply, and the stronger the alkalinity, the worse the adsorption effect.



    Application history:

    Activated carbon has been used in water purification for about 60 years, but it began to be used in wastewater treatment in 1960s. Due to the rapid development of industry, there are more and more highly toxic and difficult to biodegrade pollutants in wastewater. Activated carbon has been paid attention to because of its effective removal of these pollutants.



    In 1965, the United States built the world's first advanced treatment plant of activated carbon wastewater with production scale. In 1972, the treatment method of adding powdered activated carbon into aeration tank was successfully studied. Since the early 1970s, China began to study the technology of wastewater treatment with activated carbon, and in 1976, the first activated carbon advanced treatment unit for refinery wastewater was built.



    Classification of industrial wastewater:

    According to the chemical properties of the main pollutants in industrial wastewater, it can be divided into: inorganic wastewater mainly containing inorganic pollutants, organic wastewater containing mainly organic pollutants, mixed wastewater containing organic and inorganic substances, heavy metal wastewater, wastewater containing radioactive substances and cooling water only polluted by heat.coal pellet activated carbon For example, electroplating wastewater and mineral processing wastewater are inorganic wastewater, while food or petroleum processing wastewater is organic wastewater.



    According to the products and processing objects of industrial enterprises, they can be divided into papermaking wastewater, textile wastewater, tannery wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater, etc.



    According to the main components of pollutants in wastewater, it can be divided into acid wastewater, alkaline wastewater, phenol wastewater, chromium wastewater, organic phosphorus wastewater and radioactive wastewater.
