Description
Technical field
The invention belongs to technical field of waste water processing, be specifically related to a kind of iron-carbon micro-electrolysis filler and its preparation method and application.
Background technology
Iron-carbon micro-electrolysis technical finesse industrial wastewater, is simple and convenient to operate because of its technique and can reach the purpose of the treatment of wastes with processes of wastes against one another and the most in widespread attention.Light electrolysis is also called Inner electrolysis, the cell reaction being mainly based upon in electrochemistry, relates to the multiple effects such as oxidoreduction, electricity enrichment, physical absorption and flocculating sedimentation.Course of reaction is with ferrum as anode, and carbonaceous material is as negative electrode, and the ion in waste water is as electrolyte, thus forms cell reaction.Not only can remove part hard-degraded substance, colourity is greatly lowered, it is also possible to changing section organic form and structure, improve the biodegradability of waste water, reach the purpose of sewage disposal.
But all there is shortcomings in most of micro-electrolysis stuffing in the market, such as: after filler uses a period of time, due to insufficient strength and the corrosion of ferrum of filler, loss, caking etc. easily occurs；Or it is when processing industrial wastewater, low etc. to COD, colourity and part heavy metal removing rate.Therefore research and develop a kind of stable performance, intensity is big, activity height, good waste water treatment effect, the simple micro-electrolysis stuffing of preparation technology are extremely urgent.
Summary of the invention
Present invention aim to overcome that prior art defect, it is provided that a kind of intensity is big, activity is high, the iron-carbon micro-electrolysis filler of good waste water treatment effect.
Present invention also offers the preparation method of above-mentioned iron-carbon micro-electrolysis filler and the application in terms of Industrial Wastewater Treatment thereof.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of iron-carbon micro-electrolysis filler, it is made up of following materials by weight percentage: iron powder 40-50%, activated carbon powder 20-30%, anaerobic sludge (taking from sewage treatment plant of Zhumadian City the 3rd) 15-25%, manganese powder 3-5%, Graphene 0.1-0.5%, 3-5% hydroxypropyl methyl cellulose and 5-8% sodium silicate.
Concrete, the particle diameter of iron-carbon micro-electrolysis filler is preferably 2.5-3cm.
The preparation method of above-mentioned iron-carbon micro-electrolysis filler, it comprises the steps:
1) iron powder, activated carbon powder, anaerobic sludge, manganese powder and Graphene are weighed in proportion, (addition of water account for the 60-70% of raw material iron powder, activated carbon powder, anaerobic sludge, manganese powder and Graphene quality sum, the most preferably about the 65%) mix homogeneously that adds water obtains semi-finished product A；
2) adding hydroxypropyl methyl cellulose and sodium silicate (both are used as binding agent) in semi-finished product A, mix homogeneously obtains semi-finished product B；
3) semi-finished product B is made the spherical particle that particle diameter is 2-3cm, be subsequently placed in baking oven at 100 DEG C-120 DEG C and be dried 8h-10h, then be placed in Muffle furnace in 500 DEG C-600 DEG C roasting 10h-12h, naturally cool to room temperature, to obtain final product.
The application in terms of Industrial Wastewater Treatment of the above-mentioned iron-carbon micro-electrolysis filler.Concrete, directly iron-carbon micro-electrolysis filler is immersed in industrial wastewater, carries out under aeration condition, and to keep air water volume ratio be 3-5:1, the process time is 120min-150min.Process stands after terminating, and discharges supernatant, and waste water is disposed.Described industrial wastewater can be high COD, high chroma, wastewater from chemical industry that copper content is higher.
The present invention is directed to deficiency of the prior art, provide a kind of with iron powder, activated carbon powder, anaerobic sludge, manganese powder, Graphene, hydroxypropyl methyl cellulose and sodium silicate as primary raw material, and through weighing, pelletize, drying, the iron-carbon micro-electrolysis filler made of the step such as roasting.This iron-carbon micro-electrolysis filler preparation technology is simple, and intensity is big, uses the cycle long, for the process of industrial wastewater, COD in waste water, content of beary metal and colourity etc. can be greatly lowered.
Compared to the prior art, beneficial effects of the present invention:
1) micro-electrolysis stuffing that prepared by the present invention uses anaerobic sludge as template, after fired, microorganism in anaerobic sludge is carbonized, form cavernous structure, add the one-tenth porosity within filler and porosity, providing uniform aqueous vapor flow channel, promote the exchange of inside and outside current, the process to waste water provides bigger electric current density and more preferable catalytic reaction effect.It is simultaneously achieved the recycling of garbage；
2) containing manganese element in micro-electrolysis stuffing prepared by the present invention, wastewater treatment process primary cells reaction efficiency can be improved and prevent the passivation of filling surface, the removal of heavy metal in waste water can be promoted simultaneously；
3) micro-electrolysis stuffing prepared by the present invention adds the Graphene of trace, the bigger intensity that improve micro-electrolysis stuffing, reduces filler abrasion in use；
4) traditional micro-electrolysis stuffing is in use, it is necessary to carry out pH regulator, and the micro-electrolysis stuffing prepared by the present invention need not regulate pH when carrying out waste water and processing, it is adaptable to alkalescence and the process of neutral waste water, greatly reduces cost for wastewater treatment；
5) micro-electrolysis stuffing prepared by the present invention is when carrying out waste water and processing, and can not only effectively remove the COD in waste water and colourity, can remove the plurality of heavy metal ion contained in effluent part, such as metal copper ion etc. simultaneously.
