Description

Novel anaerobic pond in town sewage treatment system
Technical field
The present invention relates to sewage treatment fields, and in particular to the Novel anaerobic pond in town sewage treatment system.
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, and such as aerobic pool volume is big, floor space is high, capital cost is high Deng, while it is relatively low to the adaptability of sewage quality, water variation, operational effect is easily influenced by water quality, water variation.In view of Above-mentioned factor is gradually replaced by biofilm in sewage disposal.Biofilm compensates for many deficiencies of activated sludge process, such as Its stability is good, bear organic loading and the ability of hydraulic loading shock it is strong, without sludge bulking, without reflux, to organic matter Removal rate is high, 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;It is existing simultaneously Treatment tank it is bad to wastewater treatment efficiency.
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 at town sewage Novel anaerobic pond in reason system avoids the MBBR fillers of a part from swimming in the surface of sewage, improves MBBR fillers to sewage Treatment effect.
The present invention is achieved through the following technical solutions:
Novel anaerobic pond in town sewage treatment system, including aerobic tank, several MBBR fillers, aerator, aeration Pipe, anaerobic pond, anoxic pond, the aerator are located on the side wall of aerobic tank, and exposure tube is located at the interior bottom of aerobic tank, and with Exposure device connects, and is additionally provided with riser in the aerobic tank, one end of riser is inserted vertically into aerobic tank, and the other end is equipped with The both sides of transverse slat, the riser are equipped with several sliding blocks, and sliding block can along vertical direction move on riser, the sliding block It is equipped with filter screen on side wall, adjusting rod identical with filter screen quantity is additionally provided on the transverse slat, adjusting rod is interspersed in vertically It on transverse slat, and is connect respectively with each filter screen, adjusting rod can drive filter screen to be moved along vertical direction in aerobic tank Dynamic, the anaerobic pond be connected to anoxic pond, and partition board and movable plate are equipped between anaerobic pond and anoxic pond, movable plate positioned at every The top of plate, and movable plate can be moved towards partition board direction, anaerobic pond and anoxic pond be separated, the anaerobic pond and anoxic Several Ball-type packings are equipped in pond.
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 drainpipe on the aerobic tank, and is additionally provided with filter sheath on drainpipe, the anaerobic pond On be additionally provided with water inlet pipe.
Further, the both sides of the aerobic tank are also equipped with feeding port.
Further, it is additionally provided with conduit in the anoxic pond, tube at one end is connect with anoxic pond, and the other end connects with aerobic tank It connects, and is additionally provided with water pump on conduit.
Further, the bottom of the anaerobic pond and anoxic pond is equipped with driving mechanism, on the output end of driving mechanism Equipped with blade.
Compared with prior art, the present invention having the following advantages and advantages:
1, the Novel anaerobic pond in town sewage treatment system 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;
2, the Novel anaerobic pond in town sewage treatment system of the present invention, when handling sewage, sewage first into Enter anaerobic pond, Denitrifying Phosphate Accumulating Organisms anaerobic phosphorus release is carried out to sewage, after waiting for that the sewage in anaerobic pond thoroughly reacts, pulls upward Movable plate so that sewage enters to anoxic pond, and sewage carries out denitrification denitrogenation in anoxic pond and inhales phosphorus, completes denitrogenation dephosphorizing, it Sewage is entering to aerobic tank afterwards, sewage is carried out nitrification under the nitrobacteria effect that carrier surface adheres to, ammonia nitrogen It is converted into nitrite nitrogen and nitrate nitrogen.
