Description
Technical field
The present invention relates to the continuous of a kind of field of industrial waste water treatment more particularly to a kind of industrial wastewater middle and high concentration COD
Formula processing system and treatment process.
Background technique
Under the fast development of industry, China achieves economic rapid growth, while environmental pollution also becomes history something lost
The problem of staying.By effort in recent years, China achieves biggish achievement, achievement in terms of urban sewage treatment technology
It is plentiful and substantial.As a piece of " the blue sea " for waiting to open up, water process market prospects are very optimistic.According to prediction industrial research institute《It is Chinese dirty
The prediction of water treatment field market is reported with investment analysis》It has been shown that, more than 4000 families in the existing waterworks in China, sewage treatment plant 3500
More, with the gradual perfection of sewage treatment facility, wastewater treatment in China rate has risen to a high position at present.By year ends 2016, city
City's wastewater treatment rate has reached 93.4%, and county town wastewater treatment rate has also reached 87.4%.As industry environmental protection cry day edges up
Height, industrial wastewater treatment demand is ubiquitous, in factory of enterprise, is mainly distributed on electronics, plastic cement, plating, hardware, printing, food
The industries such as product, printing and dyeing.However these factories generate most of sewage needs can be just discharged into after certain processing river,
In the Cultivated waters such as sea, rivers, lakes pool, reservoir, pond.But still there are many impurity to be difficult to handle in sewage after treatment,
The especially organic matter of the waste water of high concentration COD and difficult for biological degradation, coloration is higher in water, humic acid, fulvic acid content compared with
High sewage.
Since in the sewage composition of sewage treatment plant, most of is industrial tail water, at level-one Fenton, level-one A/O
After reason, remaining organic matter is hardly degraded organic substance in water body, to make its organic matter degradation, stable water outlet up to standard, needs to use
Advanced treatment process.
The further treatment technique of waste water mainly includes physico-chemical process, bioanalysis, high-level oxidation technology etc..Physico-chemical process mainly includes
Absorption method, membrane separation process, Coagulation Method etc.；Bioanalysis includes oxidation pond further treatment technique, biological aerated filter process etc.；It is advanced
Oxidation technology includes Fenton method and class Fenton technology, photocatalytic oxidation etc..Wherein, high-level oxidation technology is the most stable can
It leans on.
High-level oxidation technology is by generating .OH (hydroxyl radical free radical) come to cannot be by universal oxidizing in sewage
The process of pollutant progress oxidative degradation.It is numerous studies have shown that the pollutant of bio-refractory usually has corresponding stability,
It is difficult to be had by common oxidants permineralization this requires there is used chemical agent enough oxidabilities thoroughly to destroy
Machine object, this trend have promoted to generate hydroxyl radical free radical as the rapid development of the high-level oxidation technology of main feature.While by
The influence of the form of catalyst, the hydroxyl radical free radical quantity and oxygen of generation are received in the hydroxyl radical free radical that traditional Fenton process generates
Changing efficiency cannot effectively play a role, and the irradiation of UV light can strengthen the yield and time efficiency of hydroxyl radical free radical, therefore at present
Development is that UV cooperates with high-level oxidation technology.And the technology is mainly characterized by：1) strengthen the yield of hydroxyl radical free radical；2) hydroxyl is improved
Efficiency of the base free radical to mineralization of organic material.This trend has promoted the advanced oxidation to generate hydroxyl radical free radical as main feature
Technology rapidly develops.
Statistics indicate that the hydroxyl radical free radical oxidant more common than other has higher standard electrode potential outside fluorine removal, because
This is with higher oxidability.The characteristics of UV collaboration advanced oxidation processes distinguish other method for oxidation is following side
Face：
A, reaction speed is fast, and the oxidation rate constant of most organic matters in the process is up to 106-109m/s；
B, applied widely, higher oxidizing potential make hydroxyl radical free radical almost can by all oxidation operations until
Mineralising；
C, reaction condition is mild, usually to temperature and pressure no requirement (NR), without carrying out in strong acid, alkaline media；
D, chain reaction can be induced, the autoxidation of organic matter is formed, so that organic matter is degraded, this is all kinds of
The independent book use of oxidant is all inaccessiable；
E, it can be used in conjunction with other processing techniques, especially as the preprocessing means of biological treatment process, difficult to degrade has
Machine object its biochemical after advanced oxidation processes processing improves mostly, to be conducive to the further degradation of bioanalysis；
F, operation is examined, is easy to equipment management；
G, copper catalyst is Ke Xunhuanliyong, avoids the generation of iron cement；
(IFBR-UASB-ICEAS handles industrial wastewater novel work to Chinese invention patent：201610485470.0) provide
A kind of IFBR-UASB-ICEAS processing industrial wastewater novel process, the technique include conditioning tank, modified Fenton fluidized bed, take off
Gas neutralization pond, coagulative precipitation tank, up-flow anaerobic sludge blanket and ICEAS reactor；Each unit is sequentially connected through water pipe, to industry
Waste water is handled.The invention carry out can process optimization, clear route is succinct；Whole COD removal rate >=95%, organic properties are dirty
Removal rate >=95% of object is contaminated, operational management is convenient, process stabilizing, and investment operating cost is low, but the invention treated COD
Content is higher, does not reach level-one A standard, and which provides only preliminary treatment methods, does not provide the COD processing of complete set
System.
Summary of the invention
To solve problems of the prior art, based on existing Industrial Wastewater Treatment there are the shortcomings that, mesh of the invention
The one kind that is to provide can be realized and combined manually with automatic control, and implement dynamic supervision, STOCHASTIC CONTROL added amount of chemical,
Prevent Treatment of Industrial Water effluent quality COD not up to standard, strong operability, effect is good, it is ensured that the treatment process system of water quality safety；And
The processing system and its technique of scientific and reasonable, practical reduction COD are provided.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：A kind of company of industrial wastewater middle and high concentration COD
Continuous formula processing system, including intermediate lift pump pond, distribution well, UV collaboration advanced oxidation pond, catalyst dewatering system, catalyst are again
Raw system；
The intermediate lift pump pond outlet connection distribution well entrance, distribution well outlet cooperate with advanced oxidation with the UV
The connection of pond entrance, the outlet of UV collaboration advanced oxidation pond are connect with the catalyst dewatering system entrance；The catalyst is de-
