Description
First, technical field
The present invention relates to sewage disposal and biological denitrificaion active carrier technology to be entered in second pond with tower method to sewage
The method and device of row biological denitrificaion processing.
2nd, background technology
A is commonly used in Modern sewage processing both at home and abroad2/ O or A/O active particle sludge and biomembrance process, with physical-chemical process
Compared to economical and practical non-secondary pollution and transfer, the complete Technical comparing of design parameter is ripe.With new material new technology and method not
Disconnected innovation.Such as MBR and SBBR methods, which are handled sewage, has been applied, because the changeable biological growth of sewage complicated is by more
The limitation of kind factor and the influence of poisonous substance, as long as a kind of change of factor just influences the overall situation.If itself strength reparation or reconstruction are leaned on completely
Active particle sludge needs up to 180 days or the longer time, and the above method is inadequate natural endowment.
There is scholar with investment, short distance nitration, carbon fiber and polyurethane to add activated carbon modified foam soft or hard material
Used with as carrier, also useful rubble, Ju grains and corrugated plating are made filtrate and sewage handled but less effective, still need to rely on from
The biomembrane that right grown cultures are formed, these effort are unsatisfactory to ammonia nitrogen removal effect.Particularly town sewage is arranged by country
Put standard and one-level A discharges are changed to by the discharge of GB 18918-2002 originals two level, can only newly-built enlarging sewage treatment plant by prior art
Or old sewage plant is transformed with new technology.
The method for creating transformation is to innovate, and we are adapted to the filter of microorganism growth with the method selection of preeictive microbiology
Material carries out screening purifying domestication and culture to nitrifier and obtains new active carrier, and dominant microflora and life have been formed on carrier
Thing film.Only the active carrier material and waste water need to can be subjected to biological denitrificaion through laundering period short time.Relevant such life
Thing denitrification activity carrier material application technology yet there are no report.
The present invention is and the scale metaplasia with the biological denitrificaion active carrier production method and technology oneself with intellectual property
The biological denitrificaion material of active carrier is produced, the technology can establish biomembrane ecological balance system, increase life in a short time
Object amount simultaneously shortens incubation time, biological denitrificaion carrier technique is striden forward a step, and experiment is proved in second pond with tower process
Using the potential and function that can give full play to biological denitrificaion active carrier.
3rd, the content of the invention
It in sewage disposal using spherical and irregular shell is raw material biological denitrificaion active carrier that the purpose of the present invention, which is,
And spheroid shell is used with to the technology for keeping away water bias current, biological denitrificaion, this place are carried out to sewage with tower method in second pond
Reason method and device presses process progress：
1st, the preparation of denitrification activity carrier：6~15mm balls are made in shellfish powder with bonding method, shell crosses 6~20mm sieves；With certainly
The nitrification and nitrococcus of oneself screening purifying domestication are cultivated denitrification carrier respectively；
2nd, Jian Ta：Can the carry carrier and other weighing loads for building fractional layer have the tower body of stack effect, and footpath post is than 1:
10 have hopper；
3rd, body is loaded：Two kinds of active carriers of spheroid and shell can mix layering according to water quality difference in 10~40% ratio
Load in tower；
The 4th, water inlet system is installed：Pacify spray thrower, 40~400m of water transfer power load in tower upper end3/(m2.h)。
