Abstract

The invention discloses a device and a method for treating organic waste water by a water plasma torch. The device comprises a water plasma torch waste water treatment reactor; the method comprises the steps of: directly using organic water to be treated as the working medium of the water plasma torch to generate a steam plasma jet, and introducing the steam plasma jet into the organic waste water to treat organic pollutants in the water; the device and method for treating the organic waste water by the water plasma torch have the advantages that the energy utilization efficiency is high, the organic waste water is rapid in degradation rate, and meanwhile the organic waste water can be converted into synthesis gas, thus achieving the resourcezation and energization of the organic waste water; the device and the method is particularly applicable to the treatment of the organic waste water which is high in concentration and difficult to degrade.

Description

technical field [0001] The invention relates to a device and a method for treating organic waste water with a water vapor plasma jet generated by a water plasma torch, belonging to the fields of environmental engineering and plasma science. Background technique [0002] At present, the technologies and methods for treating high-concentration refractory organic wastewater (liquid) mainly include chemical oxidation, incineration, electrochemical oxidation, photocatalysis, wet oxidation, etc. However, these technologies and methods all have defects of varying degrees, such as the harsh reaction conditions (high temperature and high pressure) of the supercritical water oxidation method, high requirements on the material of the reaction equipment, and blockage of the reactor and pipeline by inorganic salts; The incineration method consumes a lot of energy, and produces flue gas, fly ash, etc., causing secondary pollution to the environment; although chemical oxidation, el...
