Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment.

[0025] Such as figure 1 Shown, the step of organic wastewater ozone catalytic oxidation treatment process of the present invention comprises:

[0026] 1. Lift the pretreated organic wastewater into the self-cleaning filter through the self-priming pump. In the self-cleaning filter, most of the larger suspended solids in the wastewater are removed, and the produced water after the self-cleaning filter enters the security filter , to further remove suspended solids and colloidal substances in water;

[0027] 2. In step 1, the water produced by the security filter enters the heat exchanger of the cooling system and exchanges heat with the circulating cooling water of the cooling system. The water temperature of the waste water is reduced to about 25°C, and the cooling water is cooled by the chiller of the cooling system. Recycling below 25°C;

[0028] 3. The waste water heated up by ...

Abstract

The invention provides a high-efficiency catalytic ozonation process which is particularly applicable to purification and treatment of water bodies with organic pollutants. Pretreated organic wastewater is mixed with ozone prior to entering a catalytic oxidation tower through a micronano bubble generation device, and the catalytic oxidation tower is filled with catalytic filler materials for catalyzed oxidative degradation of organics in wastewater. The catalytic filler materials in the catalytic oxidation tower are large in specific surface, ozone catalyzing capability can be enhanced by composite metals on the catalytic filler materials, and effective utilization rate of hydroxyl free radicals can be increased. Compared with traditional catalytic treatment processes and catalytic filler materials, the high-efficiency catalytic ozonation process has the advantage of high efficiency in elimination of toxic and harmful organics in the water bodies.

Description

technical field [0001] The invention relates to a treatment method for organic waste water, in particular to an ozone catalytic oxidation treatment process and catalyst material. Background technique [0002] The pollution of refractory organic matter in water and its effective treatment have become a severe problem faced by my country's water environment work. Organic pollutants in water mainly include macromolecular natural organic matter, trace organic pollutants, odorous substances, algae and their metabolites, etc. These organic substances usually come from organic pollutants produced by industrial processes such as organic chemical industry, petrochemical industry, medicine, pesticides and herbicides. They have the characteristics of low concentration and high toxicity, and many of them can produce carcinogenic, teratogenic and mutagenic effects. It is extremely harmful to human health, and these organic substances are difficult to degrade, and are easy to amplify the...
