Non-supported ozone catalyst and use method thereof

[0059] refer to figure 1 As shown, this embodiment provides a non-supported ozone catalyst titanium disk aeration system, including a water inlet tank 1, an inlet pump 2, a non-loaded ozone catalytic oxidation tank 4, a water production tank 6, an ozone generator 8, and an ozone tail gas Destruction device 12.

[0060] The water inlet tank 1 is connected with the non-load type ozone catalytic oxidation tank 4 through the water inlet pump 2, the water inlet pipe 3 and the water inlet valve 3-1.

[0061] The non-supported ozone catalytic oxidation tank 4 is divided into water inlet channel 4-1, non-supported ozone catalyst B4-2, non-supported ozone catalyst A 4-3, supporting layer 4-4, water distribution tank 4 from top to bottom Gas distribution disc 4-5, support plate 4-6.

[0062] The non-load type ozone catalytic oxidation tank 4 is connected to the water production tank 6 through the water production pipe 5 and the water production valve 5-1.

[0063] The water production p

[0080] refer to figure 2 As shown, this embodiment provides a non-loaded ozone catalyst jet aeration system, including a water inlet tank 1, a water inlet pump 2, a non-loaded ozone catalytic oxidation tank 4, a water production tank 6, a circulation pump 14, and an ozone generator 8 , water injector 16, ozone tail gas destruction device 12.

[0081] The water inlet tank 1 is connected with the non-load type ozone catalytic oxidation tank 4 through the water inlet pump 2, the water inlet pipe 3 and the water inlet valve 3-1.

[0082] The non-supported ozone catalytic oxidation tank 4 is divided into an outlet channel 4-7, a non-supported ozone catalyst B4-2, a non-supported ozone catalyst A 4-3, a supporting layer 4-4, and a water distribution channel from top to bottom. Gas distribution disc 4-5, support plate 4-6.

[0083] The non-load type ozone catalytic oxidation tank 4 is connected to the water production tank 6 through the water production pipe 5 and the water productio

[0101] Same as Example 1, the only difference is that the volume ratio of non-supported ozone catalyst A and non-supported ozone catalyst B is 5:1.

[0102] Use the method of this embodiment to treat the biochemical effluent of certain pharmaceutical wastewater. The raw water COD is 200-300mg / L, after being treated by this system, the COD is 108-171mg / L, the COD removal rate is 43-46%, the ozone amount / COD removal amount is 1.8-2.0, and the waste water is obtained after being treated by this system Good COD removal effect and ozone utilization efficiency.
