METHOD OF SEWAGE WATER PURIFICATION Russian patent published in 2013 - IPC C02F1/30 C02F9/12 B01J19/08 

FIELD: chemistry.

SUBSTANCE: invention can be used for purification and disinfection of sewage water of small and medium-size enterprises, municipal organisations, settlements and housing estates with productivity of about 1-10 m³/hour. In order to realise the method processing of continuous water flow is performed with electron ray with energy 300-500 keV, pulse duration 20-50 ns, density of electron pulse current 5-300 A/cm² and pulse repetition rate from single pulses to 100 pulse/s. In preferable versions of method sewage water is preliminarily saturated with oxygen, or oxygen in mixture with other gases, with formation of aerosol flow. In addition, saturation with oxygen or oxygen in mixture with other gases is carried out by blowing air through water.

EFFECT: method is characterised by increase of power by 10³-10⁵ times of absorbed dose without significant increase of electron energy in ray and ensures disinfection and purification of sewage water from inorganic and organic compounds, such as phenols, crude oil products, surface-active substances.
