Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing ozone contact oxidation tank is used to treat refractory organic pollutants in water, the utilization rate of ozone is low, the reaction rate of organic pollutants and ozone is low, and the highly stable organic pollutants in water are difficult to degrade. Degradation, under normal circumstances, the reaction time between ozone and organic pollutants in water is different, the amount of ozone consumption is large, and the water treatment effect is not ideal. Provide a method to improve the ozone utilization rate of the ozone contact oxidation tank and strengthen the treatment effect

specific Embodiment approach 1

[0006] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 Illustrate this embodiment, this embodiment is accomplished like this: first place porous medium filler 1-3 between two baffle plates 1-2 in each unit cell 1-1 in ozone contact oxidation tank 1, described The porous medium filler 1-3 is composed of porous medium and the surface of the porous medium is loaded with metal or metal oxide; then through the aeration pipe 1-4, it flows into the ozone contact oxidation tank 1 equipped with the porous medium filler 1-3 with bubble flow The oxidant is passed into the oxidant in a manner, and the diameter of the oxidant bubble is 20 μm to 5 mm; the oxidant is pure ozone or a mixed gas of ozone and oxygen or a mixed gas of ozone and air; the volume percentage of the ozone and oxygen is: ozone: 0.001-10%, oxygen: 90-99.999%; the volume percentage of ozone and air is: ozone: 0.001-10%, air: 90-99.999%, the concentration of ozone is 0.1-5.0mg / L, ...

specific Embodiment approach 2

[0007] Specific implementation mode two: combination figure 1 , figure 2 , image 3 , Figure 4 Describe this embodiment, the difference between this embodiment and specific embodiment 1 is: the diameter of the oxidant bubble in this embodiment is 3mm, the volume percentage of described ozone and oxygen is: ozone: 5%, oxygen: 95% The volume percent of described ozone and air is: ozone: 5%, air: 95%, and the concentration that ozone feeds is 3.0mg / L, and keeping water temperature is 25 ℃, and the flow velocity of water flow through porous medium filler 1-3 is 0.25m / s.

specific Embodiment approach 3

[0008] Specific implementation mode three: combination figure 1 Describe this embodiment, the difference between this embodiment and specific embodiment 1 is: in this embodiment, the porous medium filler 1-3 is placed on the bottom wall 1-1-3 of each unit cell 1-1. 1 on. Arranging the porous medium filler 1-3 on the bottom wall 1-1-1 in each unit pool 1-1 can change the flow line of the water flow and avoid the occurrence of short flow, thereby prolonging the ozone contact oxidation pool 1. Pollutants contact reaction time with ozone.

[0009] Specific implementation mode four: combination figure 2 Describe this embodiment, the difference between this embodiment and specific embodiment 1 is: in this embodiment, the porous media filler 1-3 is placed on the side wall 1-1-1 of each unit cell 1-1. 2 on. Arranging the porous media filler 1-3 on the side wall 1-1-2 in each unit pool 1-1 can change the flow line of the water flow and avoid the occurrence of short flow, thereby p...

Abstract

The invention relates to a handling method of enhancing ozone availability ratio, reinforced treatment effect of the ozone contact oxidation pond. The invention solves the present problem: organic pollutant in conditioning water of ozone contact oxidation pond is non-degradable, the availability ratio of ozone is low, the degradation of organic pollutant is not exhaustive. It is accomplished as follows: first set porous media filling materials (1-3) made up of porous media and metal or metallic oxide inside every unit pond (1-1) in said ozone contact oxidation pond (1); then add oxidant whose bubble diameter is 20mum~5mm to said ozone contact oxidation pond, said oxidant is pure ozone or mixture gas of ozone and oxygen / air; the concentration of ozone is 0.1-5.0mg / L. The method in said invention is not only useful for dealing organic pollutant in ozone contact oxidation pool completely, but also enhancing the availability ratio of ozone.

Description

technical field [0001] The invention relates to a treatment method of an ozone contact oxidation tank, in particular to a method for improving the ozone utilization rate of the ozone contact oxidation tank and strengthening the treatment effect. Background technique [0002] With the rapid development of industry and the continuous improvement of human material living standards, the serious pollution of organic pollutants to the water environment has become a common problem. In recent years, the use of advanced ozone oxidation water treatment technology to treat refractory organic pollutants in water has been widely used. However, the existing ozone advanced oxidation technology simply utilizes the reaction of the ozone in the ozone contact oxidation tank with the organic pollutants in the water to degrade the organic pollutants in the water. The use of the above-mentioned ozone advanced oxidation water treatment technology has the problem that the utilization rate of ozone...
