Further, several separate mesh are arranged in the rising inside pipe wall interval, and the separate mesh separates the tedge
For several marker spaces, the hollow ceramic ball is arranged in the marker space, ensures the stabilization of filler scope of activities, reduces simultaneously
The use of filler, filler, and will not there is a situation where block outlet pipe without filling up each marker space.
Further, the rising pipe internal surface is coated with titanium dioxide-coated layer, makes sewage and more titanium dioxide
Catalyst contacts.
Further, it is provided with blowout prevention plate at the top of the tedge, prevents sewage from being overflowed out of tedge.
Further, the tedge and the down-comer are pipe, and the two coaxial arrangement ensures that flow is unobstructed, and
The sewage uniform alumina of each section is decomposed.
Further, a diameter of 1/4-1/2 for rising pipe diameter of the down-comer, the diameter of down-comer is small, water
Stream is big in decline velocity in pipes, and shearing stress is larger, generates many minute bubbles, increases the dissolution rate of ozone in water, tedge
Diameter is big, and flow velocity is slow so that the time of contact of sewage and catalyst is long, improves oxygenolysis efficiency.
Preferably, the 1/3 of a diameter of rising pipe diameter of the down-comer.
A kind of advanced sewage oxidation processing equipment of the present invention, advantageous effect compared with prior art are:Pass through literary mound
In pipe realize that the mixing of ozone self-priming, while deep aeration improve the dissolved efficiency and oxidation efficiency of ozone, rising refluxing stage
Catalyst is set, further increases the oxidation efficiency of ozone, the oxygenolysis rate of sewage is high, and processing is thorough.
Description of the drawings
Fig. 1 is overall structure of the present invention.
Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, a kind of advanced sewage oxidation processing equipment, including tedge 1, Venturi tube 2 and down-comer 3, institute
It states Venturi tube 2 and is inserted into 1 top of the tedge, the entrance of the Venturi tube 2 stretches out the tedge 1 and and dredge pump
4 connections, entrance of the sewage stream that dredge pump 4 generates Jing Guo Venturi tube 2 forms high-velocity flow, in the throat of Venturi tube 2
Surrounding forms negative pressure, and air inlet pipe 5 is arranged the throat in the Venturi tube 2 and is stretched out from 1 side of the tedge, the air inlet
Pipe 5 is connected to ozone generating-device, due to suction function, air inlet pipe 5 from sucking ozone, ozone and sewage formed liquid gas mixed flow from
