Perspectivity of Application of Carbon Fibrous Sorbents for Water Treatment for Technogenic Pollutions

Summary

The main characteristics and properties of carbon fibrous sorbents for their application in sorption treatment of surface water for oil products and phenols are studied. It is established that the activated fibrous sorbent has considerably better kinetics of sorption than traditional granulated carbons. It is also established that the sorption capacity and coefficient of protective action of a layer of carbon fibrous sorbents by 6 times higher by phenol and efficiency of treatment by 1,5 times higher comparing with granulated activated carbons. The high efficiency and perspectivity of the use of carbon fibrous sorbents in combination with ozonization for removal of organic pollutants from surface water and wastewater are revealed. The technological decisions making it possible to reduce the size of equipment by 20–100 times are found. At the same time the sorption capacity by special-purpose biotoxicants increases by 1,5–3 times comparing with traditional materials at considerable reduction of costs for construction of large objects.
