Description
Technical field
The invention belongs to technical field of sewage, and in particular to mention mark transformation biological treatment dress for a kind of industrial wastewater
It sets and treatment process.
Background technique
Industry continues to develop, and the type and quantity of waste water also rapidly increase, water pollution seriously threaten the mankind health and
Safety.Industrial wastewater complicated component, containing there are many different polluters, and polluter and concentration in all types of industries waste water
There is biggish difference, it is more difficult to handle.
Environmental pressure is got worse now, every profession and trade is applicable in discharge standard and is continuously improved, and water re-using rate requires further tight
Lattice.If " planning of national environmental protection " 12th Five-Year Plan " " is explicitly pointed out and thoroughly applied the Scientific Outlook on Development, make great efforts to improve ecology text
Bright level deepens the emission reduction of major pollutants total amount.Plan that the major pollutants also fixed to China's " 12th Five-Year Plan " period are total simultaneously
Measure the emission reduction targets and task of discharge --- compared with 2010, COD and sulfur dioxide (SO2) emissions total amount decline 8%, ammonia
Nitrogen and discharged nitrous oxides total amount decline 10%.
Waste water by each business processes, recycle and Treated sewage reusing after, discharge the enrichment such as COD difficult to degrade, salinity in water
Accumulation, although wherein COD is not high, compared with difficult for biological degradation, and high conductivity environments influence microorganism growth and activity.Utilize object
Physicochemical method processing cost is larger, and such waste water can not be effectively treated in conventional bioremediation.
Biological flow bed (biological fluidized beds, BFBs) be at the beginning of the 70's of 20th century, by
The U.S. is first begin to carry out development and application.The technique is to utilize fluidised concept on the basis of biofilm
It is operated, is a kind of processing of enhanced biological, the high-performance bio treatment process for improving microbial degradation organic matter ability, overcomes
Disadvantage is easily blocked present in static bed biomembrane method.
U.S. Jeris Johns et al. successfully developed anaerobic organism flowing bed technique and had applied for patent in 1973,
The technology is for removing BOD5And NH3The nitrification processing of-N, BOD removal rate is up to 93% within the residence time of 16min.The U.S.
Ecolotrol company obtains biological flow bed processing waste water in the biological flow bed technique of HY-FIO of exploitation in 1975 for the first time
Patent, and it is used for two tertiary treatment of waste water.Research of the Japan in terms of the mid-1970s have started fluidized bed, is conceived to
The wastewater treatment of middle-size and small-size factory, representative is Mitsubishi and Su Tian company.Anoxkaldnes was 80 years 20th century
In generation, has researched and developed the patented technology of moving bed biological membrane process (M BBR/Moving Bed Bio-film Reactor),
It 1989, is completed for use using first municipal sewage plant of the technique, hereafter the technique and the combination with other techniques
Technique is successfully applied in 47 more than 500 national cities and industrial effluent treatment plant.
Nitrogen is an important indicator in waste water, Denitrogenation be always domestic and foreign scholars' concern main problem it
One, the biological denitrificaion of ammonia nitrogen mainly includes that two process needs of nitrification and denitrification are completed under aerobic and anaerobic condition.It passes
The biological denitrification process of system mainly has oxidation ditch (Oxidation Ditch) technique, A2/O(Anaerobic Anoxic Oxic)
Technique, SBR (Sequencing Batch Reactor) technique.But the generally existing treatment effeciency of traditional technique is low, capital cost
With the features such as high, operational process is complicated.Dutch Delft polytechnical university is nineteen ninety and 1997 fraction of the year you can well imagine and success is developed
Anammox (Anammox) technique and short-cut nitrification-denitrification (SHARON) technique.Third in 1999 etc. is proposed entirely
Autotrophic type nitrogen removes (CANON) technique, and the denitrification process efficiency that these are newly emerged in large numbers is higher, but the control of practice condition is more tight
Lattice, wastewater environment are more demanding.
Therefore, it is necessary to propose a kind of mentioning for industrial wastewater for the difficult point of degrade in existing wastewater treatment COD and denitrogenation
