Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a method of improving the ponds MBBR anaerobic nitrification efficiency.
Background technology
It is well known that with process and the population expansion drastically of modernization industry, water pollution problems has become society
One of focus, the method for sewage disposal at present mainly active sludge and biofilm two major classes：Activated sludge process is from 20 generation
It since Ji Chu Britain starts, has reformed possessed a variety of methods of operation after decades of development, simultaneously because its fabulous dirt
Water treatment efficiency and be increasingly becoming everybody approval comparative maturity technique；Biofilm is to utilize the biology being attached on filler
To a kind of technique that water body is purified, also rapidly developed and improved in recent years, proved by operative practice, activity is dirty
Though mud method is more mature, there is also many disadvantages and deficiencies, such as pond body volume is big, floor space is high, capital cost is high,
Relatively low to the adaptability of sewage quality, water variation simultaneously, operational effect is easily influenced by water quality, water variation.In view of upper
Factor is stated, is gradually replaced by biofilm in sewage disposal.Biofilm compensates for many deficiencies of activated sludge process, such as it
Stability it is good, bear the ability of organic loading and hydraulic loading shock it is strong, without sludge bulking, without reflux, organic matter is gone
Except rate height, reactor it is small, sewage treatment plant's floor space is small the advantages that.But biofilm also has its distinctive scarce
It falls into, as the filtrate in biofilter easily blocks, need to periodically backwash while aerator is more under fixation filler and filler
Change carrier granular more difficult, in biological fluidized-bed reactor only under fluidized state competence exertion effect, technique stabilization
Property is poor etc..The shortcomings that between both the above technique and deficiency, moving bed biofilm reactor (MBBR) are come into being.
Traditional MBBR technological principles are by adding a certain number of MBBR fillers into reactor, improving in reactor
Biomass and biological species, to improve the treatment effeciency of reactor.Since packing density is close to water, so in aeration
When, with water in the state that is thoroughly mixed, the environment of microorganism growth is gas, liquid, solid three-phase.The collision of MBBR fillers in water and
Shear action keeps air bubble more tiny, increases the utilization rate of oxygen.In addition, being all had inside and outside each carrier different
Biological species, some anaerobic bacterias of growth inside or facultative aerobe, external preferably bacteria, carrier each in this way are a minisize reaction
Device makes nitration reaction and anti-nitration reaction exist simultaneously, to improve treatment effect.But the existing ponds MBBR are being added one
When the MBBR fillers of fixed number amount, uppermost MBBR fillers will be floated upward by the effect of buoyancy, force uppermost MBBR
Filler swims in the surface of sewage so that MBBR fillers can not effectively be handled the sewage in the ponds MBBR.
Invention content
The technical problem to be solved by the present invention is to overcome deficiency in the prior art, and it is an object of the present invention to provide a kind of raising
The method of the ponds MBBR anaerobic nitrification efficiency avoids the MBBR fillers of a part from swimming in the surface of sewage, improves MBBR fillers pair
The treatment effect of sewage.
The present invention is achieved through the following technical solutions：
A method of the ponds MBBR anaerobic nitrification efficiency is improved, is included the following steps：It is injected first into pond body pending
Sewage, filter screen is then pulled by adjusting rod upward so that filter screen is respectively positioned on the top layer of pond body, then by feeding intake
MBBR fillers are put into mouthful into pond body, nethermost filter screen is then pushed by adjusting rod so that filter screen is by MBBR fillers
Filter screen is limited in the following, putting into MBBR fillers into pond body then through feeding port, then second is pushed by adjusting rod
Filter screen equally continues the lower section that MBBR fillers are limited in the filter screen, is iteratively repeated above-mentioned steps so that MBBR fillers position
In the lower section of filter screen, aerator is finally opened, oxygen is conveyed to pond body by aeration tube.
Further, including pond body, several MBBR fillers, aerator, aeration tube, the aerator are located at pond body
On side wall, exposure tube is located at the interior bottom of pond body, and is connect with exposure device, is additionally provided with riser in the pond body, and the one of riser
End is inserted vertically into pond body, and the other end is equipped with transverse slat, and the both sides of the riser are equipped with several sliding blocks, and sliding block can be perpendicular
It is moved along vertical direction on plate, filter screen is equipped on the side wall of the sliding block, be additionally provided on the transverse slat and filtering netting index
Identical adjusting rod is measured, adjusting rod is interspersed on transverse slat vertically, and is connect respectively with each filter screen, and adjusting rod can drive
Filter screen moves along vertical direction in pond body.
Further, the both sides of the riser, which are equipped with, is respectively positioned on the matched sliding slot of sliding block, sliding block in sliding slot, sliding block energy
It is enough to be moved in sliding slot.
Further, restraining position ring block is all provided on the adjusting rod, spacing ring is connect by screw thread with adjusting rod, and is adjusted
Pole is respectively positioned on the top of transverse slat.
Further, it is additionally provided with water inlet pipe and drainpipe in the pond body, and is additionally provided with filter sheath on drainpipe.
Further, the both sides of the pond body are also equipped with feeding port.
Compared with prior art, the present invention having the following advantages and advantages：
A kind of method improving the ponds MBBR anaerobic nitrification efficiency of the present invention utilizes setting when handling sewage
Several filter plates separate MBBR fillers, while limiting MBBR fillers and floating upward, effectively prevent the floating of MBBR fillers
On the upper layer of sewage, so that the sewage in reaction tank lower layer can also be reacted with MBBR fillers, improve to sewage
Treatment effect.
