Abstract
The invention discloses a kind of activated carbon recovery process, comprise the following steps：（1）Terminal waste water removes most suspended substances matter by sand filter；（2）Sand filter water outlet enters photochemical system by elevator pump, adds strong oxidizer and blasts air, UV light is produced under microwave-excitation, violent chemical oxidation reaction occurs；（3）Photochemical water outlet enters microwave plasma fortified charcoal absorption system, by charcoal absorption organic matter and a small amount of suspension, then through microwave plasma oxidation organic matter, microwave plasma regenerated carbon, keeps the optimum activity of activated carbon；（4）Waste water after microwave plasma fortified charcoal absorption system effluent reuse in circulation.The beneficial effect of the invention is：Actinic reactor ensures that the colourity of waste water reaches reuse requirement, while removes certain COD；Microwave plasma fortified charcoal absorption system ensures that colourity, COD and the suspension of final waste water reach the requirement of reuse.
Description
Technical field
The present invention relates to technical field of active carbon, specially a kind of activated carbon recovery process.
Background technology
The activated carbon of high heap density can bear faster backwash water velocity, and hot recycling process has bigger flexible
Property；There are more activated carbon products in unit volume, therefore, to adsorption capacity identical product, the life-span is longer, has fine
Recovery prospect.
The content of the invention
It is an object of the invention to provide a kind of activated carbon recovery process, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of activated carbon recovery process, including following step
Suddenly：
（1）Terminal waste water removes most suspended substances matter by sand filter；
（2）Sand filter water outlet enters photochemical system by elevator pump, adds strong oxidizer and blasts air, is produced under microwave-excitation
Raw UV light, occurs violent chemical oxidation reaction；
（3）Photochemical water outlet enters microwave plasma fortified charcoal absorption system, by charcoal absorption organic matter and on a small quantity
Suspension, then through microwave plasma oxidation organic matter, microwave plasma regenerated carbon, keep the optimal work of activated carbon
Property；
（4）Waste water after microwave plasma fortified charcoal absorption system effluent reuse in circulation.
Preferably, the strong oxidizer is ozone.
Preferably, the step（2）In, air themperature is blasted as 30 degrees Celsius.
Preferably, the sand filter is advection filter tank.
Compared with prior art, the beneficial effects of the invention are as follows：Actinic reactor ensures that the colourity of waste water reaches reuse and wanted
Ask, while remove certain COD；Microwave plasma fortified charcoal absorption system ensure the colourity of final waste water, COD and
Suspension reaches the requirement of reuse.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
The present invention provides a kind of technical scheme：A kind of activated carbon recovery process, comprises the following steps：
（1）Terminal waste water removes most suspended substances matter by sand filter, it is ensured that turbidity and suspension reach reuse requirement.Sand filtration
Pond after certain time using needing to carry out backwash regeneration.
（2）Sand filter water outlet enters photochemical system by elevator pump, and during actual motion, sand filtration water outlet is first through introducing photochemical reaction
Device, add strong oxidizer and blast air, UV light is produced under microwave-excitation, air is under the strong catalytic action of UV light, production
Violent chemical oxidation reaction occurs for raw ozone, Cooperative oxidant, makes long-chain macromolecule or the difficult drop containing phenyl ring, azo structure
Chain rupture occurs for solution pollutant, ring opening is partially or completely decomposed, and destroying the chromophoric group of dye molecule makes its decolouring.Light
Changing reactor ensures that the colourity of waste water reaches reuse requirement, while removes certain COD.Whether oxidant adds in actinic reactor
Enter, non-polar ultraviolet light source is opened how much depending on the water quality of waste water and water outlet requirement.
（3）Photochemical water outlet enters microwave plasma fortified charcoal absorption system, by charcoal absorption organic matter and on a small quantity
Suspension, then through microwave plasma oxidation organic matter, microwave plasma regenerated carbon, keep the optimal work of activated carbon
Property.The washing of waste water effluent reuse recirculated water, stained clot-h in enterprise after microwave plasma fortified charcoal absorption system
Etc. process.Microwave plasma fortified charcoal absorption system ensures that colourity, COD and the suspension of final waste water reach reuse
Requirement.Whether microwave plasma device is opened depending on water quality situation.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
