Description
Technical field
The present invention relates to a kind of ozone high grade oxidations to remove COD of sewage device, more particularly, to one in vapor tight tank body
Using water spray and interval ozone addition manner, realized under conditions of being equipped with certain positive pressure to spray sewage advanced oxidation removal
COD, the purpose equipment faded and sterilized.
Background technique
People have generally proved that ozone is a kind of good advanced oxidation substance, can be used to remove COD of sewage, fade
And sterilizing.
People generally use ozone high grade oxidation to remove COD of sewage at present, are all the bottoms that ozone is imported into cesspool
Portion allows ozone to dissolve catalytic oxidation in sewage, these inventions include: 201510579361.0,201520654384.9,
201620564688.0 etc., all there is the leakage problem that residual ozone overflows reaction tank in these modes, bring to external environment smelly
Oxygen contamination.
Summary of the invention
In the ozone high grade oxidation of sewage treatment, in order to avoid overflowing secondary pollution of the ozone of oxidation pond to the external world,
Also simultaneously in order to make full use of ozone source, the present invention is to use a closed cycle of ozone oxidation unit, which solves
The spilling of residual ozone reveals pollution, while having saved the generation cost of ozone.
The device is using a closed tank body, which is cylindrical shape, and a sewage is equipped on the tank body and is entered
Pipe and a discharge pipe, sewage is provided with certain height limitation in the tank body, and the ozone injected in sealed shell of tank is in dirt
The surface of water liquid, which offers a saving high energy consumptions required when injecting to water bottom.
Be in the intracorporal sewage of the tank its tank body inner top is evacuated to from bottom using an outer circulation pipeline and water pump, and from
Top is sprayed downwards using spray head, and ozonizer nozzle is equipped with more than the intracorporal liquid level of the tank, and the ozonizer is outer by one
Circulating gas pipe and air pump make to be enclosed in the ozone in tank body on liquid level and form bottom-up flowing, and with from up to down
Spray waste water oxidation.
Cycle of ozone tracheae outside tank body is connect with an ozone generator, which uses gap discharge
Mode generates ozone, and is filled into vapor tight tank body using slotted mode.It is ozoniferous that this gap discharge mode also saves production
Energy consumption.
It is equipped with a vent valve in top of the tank, after valve is closed, ozone is filled with into tank body, tank body is interior just certain
Direct draught realizes the catalytic oxidation of effluent cycle and cycle of ozone, and after ozone-depleting is used up, the deflation valve of top of the tank is certainly
To normal-pressure situations, then deflation valve turns off the dynamic intracorporal gas pressure of toilet-cleaning jar of opening, and re-fills new ozone
Continue oxidation process.
The cyclic oxidation process that gap is filled with ozone, which is continued until, reaches set to the oxidation processes index of sewage
Until target.
The present invention is that a kind of pulsed discharge is combined to produce ozoniferous oxidation unit, and chips washing system is: ozone utilizes
The features such as rate is high, reveals in an atmosphere without ozone, equipment power saving, low cost.
Detailed description of the invention
With reference to the accompanying drawing to further description of the present invention.
Fig. 1 is that a kind of ozone high grade oxidation of the embodiment of the present invention removes COD of sewage apparatus structure schematic cross-sectional view.
Specific embodiment
It is the detailed description of the specific embodiment of the invention referring to attached drawing 1.It is characterized in that using a closed tank body 100,
The shape of the tank body 100 is cylindrical shape, and tank body material is that one is equipped on the tank body using stainless steel or glass steel material
Sewage inlet pipe 102 and a discharge pipe 103, the sewage in the tank body 100 are provided with certain height limitation.
Referring to attached drawing 1, the sewage in tank body 100 is to be evacuated to using an outer circulation pipeline 107 and water pump 106 from bottom
Top in tank body 100, and sprayed downwards from top using spray head 108, it more than the intracorporal liquid level of the tank is equipped with ozonizer and sprays
Mouth 109, the ozone form the ozone being enclosed on tank body liquid level 101 by an outer circulation tracheae 113 and air pump 112
Bottom-up flowing；Cycle of ozone tracheae 113 outside tank body 100 is connect with an ozone generator 110, which occurs
Device 110 generates ozone using gap discharge mode, and is filled into closed tank body 100 using slotted mode.
Referring to attached drawing 1, it is equipped with an automatic air release valve 114 at the top of tank body 100, after valve 114 is closed, to tank body
It is filled with ozone in 100, just the catalytic oxidation of effluent cycle and cycle of ozone is realized in certain direct draught in tank body 100, when smelly
After oxygen consumption is used up, the deflation valve 114 of top of the tank automatically opens the gas pressure in release tank body 100 to normal pressure shape
State, then deflation valve 114 turns off, and re-fills the oxidation process that new ozone continues next period.
The cyclic process that gap ozone is filled with is until the oxidation processes index to sewage reaches set target.
It after sewage 101 in tank body 100 is handled well, then opens the valve 105 of drainpipe 103 and discharges water, then open 102 valve of water inlet pipe again
Door 104 enters sewage to be processed.
Invention is described in conjunction with specific embodiments above with reference to attached drawing, however, it is necessary to which explanation, is not taking off
In the case where from the spirit and scope of the present invention, can to above-described embodiment many modifications may be made and modification, these change and repair
Change and all falls in the range of claim restriction of the invention.
