Description
Technical field
The present invention relates to a kind of Inner electrolysis reactor and its applications, more particularly, to a kind of multistage fortifying catalytic redox
It is aerated Inner electrolysis reactor and its application.
Background technology
Light electrolysis is to be constituted primary battery with iron and carbon, by the complicated redox reaction occurred on positive and negative anodes, and profit
The effects that being enriched with physical absorption and flocculation with the electricity of primary battery itself improves the biodegradability of waste water, to reach Wastewater Pretreatment
Purpose.
It is domestic in recent years more and more to internal electrolysis research, especially to waste water such as plating, printing and dyeing and chemical dyestuffs
It is widely used in processing, and has obtained engineering application, but productivity internal electrolysis reactor is mostly filter tank form, some uses
Glass-lined steel steel equipment, some use reinforced concrete constructional work.Find the existing aeration Inner electrolysis reactor (patent No.
ZL200520098793.1) and Strong oxdiative Inner electrolysis reactor (patent No. ZL20032011500.3), built-in iron carbon materials are all used
Material, bottom of pond are equipped with large resistance underdrain system.There are following points in this kind of form internal electrolysis reactor practical application：
(1) replacement is difficult
In Inner electrolysis reactor, carbon is not consumed as cathode, and iron enters for iron ion in water as anodic conversion, therefore interior
The main consumption iron of electrolysis, with the passage in reaction time, iron filings are constantly consumed, will shadow after iron filings are reduced to a certain extent
Ring the treatment effect of Inner electrolysis, it is necessary to supplement iron filings.If being added directly iron filings from Chi Ding, new iron filings and carbon granules cannot be mixed fully
It closes uniformly, influences the treatment effect of Inner electrolysis.If filler all cleared out, the new filler mixed, this mistake are reloaded
Journey workload in real process is very big, while needing larger place, implements more difficult.
(2) reaction column blocks
With the growth of internal electrolysis flocculating bed run time, the meeting more and more suspended matters of agglomeration in filler, in addition metal
The concentration of hydroxide and to suspended matter suction-operated, it will block filler hole.Therefore it need to periodically backwash, due to iron filings ratio
Weight is larger, needs very big back washing strength.Thus necessary mating larger equipment in engineering, increases cost of investment.
(3) iron filings lump
In internal electrolysis flocculating bed, most common filler is steel bits and cast-iron scrap, and steel bits phosphorus content is relatively low, Inner electrolysis
React slower, poor processing effect；Cast-iron scrap phosphorus content is high, high treating effect, but iron filings intensity is low, easily crushes, when with processing
Between increase, the grain size of iron filings is gradually reduced, and since cast-iron scrap intensity is low, is easily crushed to powdered and is lumpd, make Inner electrolysis
There is channel in method flocculating bed, and treatment effeciency reduces.
(4) Treatment of Sludge
Internal electrolysis usually carries out in acid condition, and iron filings consumption is big under acid condition, and demodulating pH in the process will production
Raw a large amount of iron cements increase certain burden to sludge dewatering process, bring to the disposition of sludge containing a large amount of iron in sludge and centainly ask
Topic.At present generally waste residue is sent to iron-smelter to dispose or blend and make construction material, it is also contemplated that made magnetic material with iron cement, close
It needs to further investigate and put into practice in the handling problems of iron cement.
(5) after engineering amplification, treatment effect declines
Whether the tectonic sieving of reactor is reasonable, directly affects the quality of micro-electrolysis reaction effect.Generally, in laboratory institute
The light electrolysis experiment of progress is mostly in smaller container, and sewage can come into full contact with filler, and reaction is more abundant；But
When light electrolysis is applied in Practical Project, due to the amplification of reactor size, the variation of reaction condition so that hold in reaction process
It is hardened that short stream, dead angle, iron filings easily occur, cause to react insufficient, treatment effect is decreased obviously.
(6) daily maintenance and operating cost are high
Micro-electrolysis reactor is broadly divided into two class of fixed bed and agitated bed.Fixed bed exactly fixes iron filings and carbon powder particle
In bed body, so that waste water is passed through the iron carbon filler layer in bed and micro-electrolysis reaction occurs.Agitated bed generally uses blender that will give up
Water is mixed with iron filings and carbon granules.Either all there is the hardened problem of iron filings in fixed bed or agitated bed, influence treatment effect, hardened
Problem brings very big difficulty to the daily maintenance of equipment and operation, and maintenance cost and operating cost is caused to increase.
(7) high energy consumption, treatment effeciency are low
Why micro electrolysis tech is able to extensive use, and being exactly it, low energy consumption, efficient.However common micro- electricity
Solving reactor, there are many deficiencies, leads in Practical Project reaction process that mixing, mass transfer, diffusion effect are bad, causes to match and is arranged
Standby energy consumption increases, and the operating cost of medicine consumption and equipment increases.
