Abstract

The invention discloses an irradiation processing method for acrylonitrile waste water, which belongs to the field of nuclear technology application and environmental protection. The method mainly makes use of the principle that ionizing radiation can induce acrylonitrile to have a polyreaction, enables the acrylonitrile in the waste water to have the polyreaction through the ionizing radiation; and then acrylonitrile polymer deposit is separated from the water phase through a filtration method so as to realize the aim of removing the acrylonitrile from the waste water. The method can effectively remove the biologically toxic acrylonitrile pollutant in the high-concentration acrylonitrile waste water. The method is a waste water processing technology with high efficiency, economy and environmental friendliness.

Description

technical field

[0001] The invention relates to a method for treating acrylonitrile wastewater, in particular to a method for treating acrylonitrile wastewater by using ionizing radiation technology (such as gamma rays or electron beams). Background technique

[0002] Acrylonitrile is an important organic chemical raw material widely used in many industrial fields such as synthetic fiber, synthetic chemistry and synthetic rubber. However, a large amount of industrial wastewater containing toxic and harmful substances is usually produced during the production of acrylonitrile. Acrylonitrile wastewater mainly contains high concentrations of inorganic cyanide and organic nitrile substances such as acrylonitrile and acetonitrile. Due to its toxic, harmful and refractory characteristics, acrylonitrile wastewater is difficult to be effectively treated by traditional physical and chemical methods and biological methods.

[0003] At present, the treatment methods of acrylonitrile ...
