Analysis of modern state of radiation purification technologies of water polluted with oil products

Full text: In this work the modern state of methods and technologies on radiation purification of waste and sea water polluted with oil products is analyzed. Technologies based on ultraviolet (UV), electro plasma, magnet and radiation purification are considered. It is shown, that radionuclide γ-installations have following advantages:· for operational personal the specific qualification is not required and personnel quantity may be reduced to minimum (2-3 person for equipment);· high penetrability of γ-radiation;· low dose rate ∼10Gy/s. These technologies have also significance economic, ecologic, and other advantages versus to existing traditional methods. It is also shown, that among radiation purification methods of waste and sea water electron-beam treatment has specific actuality. It allows: · to decrease concentration of harmful ingredients down to limits,it is also shown that among of technologies of radiation purification of waste and sea water an electron- beam treatment has specific actuality. It allows: ·to decrease concentration to harmful ingredients down to limits acceptable purification system; ·to increase of clarity of water by removing of color matters; ·to produce purification without using of additional ingredients; The technology of application of frequency high-current electron beams for purification and disinfection water also is considered. The advantages of this technology are: · simultaneous on all water parameters; · absence of consumed materials; · multiple-factor action on all chemical impurities; · affection of microorganisms of all types; · flexibility and simplicity of operation of purification degree by increasing/decreasing of dose rate.In present work it is also shown that one of perspective directions of radiation purification is interfacial action of radiation and heat. The radiation-thermal method of purification of water from heptanes is considered. It is shown, that at absorbed dose 2-3 kGy at a temperature of 350-400C up to 85% of heptanes is decomposed in gas hydrocarbons. Thus, as seen from literature review on purification technology of polluted water, radiation-chemical purification is one of perspective applied for purification of polluted water
