Embodiment 1

[0017] Activated carbon particles loaded with 2% iron phthalocyanine are used to treat dye wastewater. When the activated carbon is saturated, the activated carbon is immersed in a 0.3% hydrogen peroxide solution. After 60 minutes, the activated carbon is washed with water. The activated carbon can continue to be recycled.

Embodiment 2

[0019] Use activated carbon particles loaded with 2% cobalt phthalocyanine to treat nitrophenol wastewater. When the activated carbon is saturated, the activated carbon is immersed in a 0.5% mass concentration of hydrogen peroxide solution. After 30 minutes, the activated carbon is washed with water. The activated carbon can continue to be recycled.

Embodiment 3

[0021] Use activated carbon particles loaded with mixed phthalocyanine (2% iron phthalocyanine and 2% cobalt phthalocyanine) to treat trichlorophenol wastewater. After the adsorption of activated carbon is saturated, the activated carbon is immersed in 0.3% mass concentration of chlorine dioxide solution for 30 After 10 minutes, the activated carbon is washed with water, and the activated carbon can continue to be recycled.

Abstract

The invention relates to a handling method of organic wastewater. The method comprises using an active carbon material loaded with metal phthalocyanine to adsorb organic pollutant in the wastewater, immersing the active carbon material in water solution including oxidizer after saturation absorbing, or directly adding the active carbon material loaded with metal phthalocyanine and the oxidizer into the organic wastewater, catalyzing and degrading the organic pollutant, thereby the active carbon material is capable of regenerating and being used repeatedly. The handling method can be used for handling various organic wastewaters like phenol organic wastewater which is difficult to degrade, dye waste and the like or recycling intermediate water. The invention has the advantages of simple method, low costs, perfect treatment effect of the organic wastewater and the like.

Description

technical field [0001] The invention relates to a method for treating organic wastewater, which belongs to the technical field of chemistry and water treatment. Background technique [0002] Organic wastewater is the most important type of industrial wastewater. Many organic pollutants have high chroma, high toxicity, and are difficult to biodegrade, causing serious damage to the environment. At present, the methods for treating organic wastewater mainly include: physical treatment methods, including adsorption methods and membrane separation technologies, etc.; physical and chemical treatment methods, including flocculation precipitation methods and electrochemical degradation methods, etc.; chemical oxidation methods, including Fenton reagent oxidation methods and ozone Oxidation methods, etc.; biological treatment methods, including aerobic and anaerobic treatment technologies; and high-temperature deep oxidation methods, mainly including wet air oxidation, supercritical ...
