Abstract

The invention discloses a method for degrading organic wastewater based on cooperation of natural tourmaline and hydrogen peroxide, and particularly relates to the field of organic pollutant treatment. The method comprises the steps of preparation of tourmaline powder and treatment of organic matter wastewater. Natural elbaite which is rich in source, low in price, non-toxic and harmless and good in cycling stability and hydrogen peroxide are adopted to synergistically degrade acidic organic wastewater, hydroxyl free radicals with strong oxidizing property are generated, and organic pollutants are successfully degraded. The use method of the natural elbaite is simple, the catalytic process is simplified, the cost is reduced, and the degradation process of the acidic organic wastewater becomes more environment-friendly. An example is provided for safely and effectively degrading organic pollutants by utilizing the pyroelectricity of tourmaline.

Description

technical field [0001] The invention relates to the field of organic pollutant treatment, in particular to a method for degrading organic wastewater based on natural tourmaline and hydrogen peroxide. Background technique [0002] As an important method of water treatment, advanced oxidation technology has been widely used in production. The current advanced oxidation technologies mainly include Fenton oxidation, photocatalytic oxidation, ozone oxidation, ultrasonic oxidation, wet oxidation and supercritical water oxidation. The Fenton oxidation method has the advantages of mild reaction conditions, simple operation, and wide application range. However, the catalyst used in the Fenton oxidation method will introduce heavy metal ions into the water and generate a large amount of sludge, which limits its applicability; The catalytic oxidation method has strong oxidation ability and wide application range, but the oxidation is not complete and the utilization rate of light is l...
