Abstract
A lateral flow aerated biological filtration pool, which comprises a pool body, a water inlet pipe and a water outlet pipe, the inside of the pool body is staggered arranged in S shape with filling frames, and the inside of the filling frame is provided with fillings. The inside of the same filtration pool is separated in sequence with an ozone area, a good oxygen area and a segment area which are connected in sequence. An aerated system is arranged between the filling frames in the good oxygen area. The biological filtration pool inherits the advantages of traditional aerated biological filtration pool such as good processing effect and stable and reliable operation, at the same time, avoids the possibility of that the filtration pool is blocked, which saves the complex and costly anti-cleaning system of the traditional aerated biological filtration pool.
Description
Technical field:
The utility model belongs to sewage disposal, environmental protection technical field, is specifically related to a kind of lateral flow biological aerated filter.
Background technology:
Look into newly by science and technology, do not see report at present both at home and abroad as yet relevant for lateral flow biological aerated filter.Existing filter tank mostly is upward flow and following pattern to stream.In sewage disposal technology, to compare with activated sludge process, it is strong that BAF has processing power, good treatment efficiency, anti impulsion load, flora is rational in infrastructure, be subjected to temperature to influence advantages such as little.But traditional BAF is stopped up easily, when practical engineering application the filter back washing system need be set.These back-purge systems are often very complicated, and involve great expense, and operational management is also comparatively complicated.These shortcomings have directly restricted the widespread use of BAF in sewage treatment area just.And this device can address this problem preferably.
Summary of the invention:
The utility model is at traditional BAF above shortcomings, designed a kind of novel lateral flow biological aerated filter, it is good that it has inherited traditional BAF treatment effect, advantages such as stable and reliable operation, simultaneously, avoid the blocked possibility in filter tank again, saved the back-purge system of traditional BAF complex and expensive.
This BAF comprises pond body, filler, water inlet pipe and rising pipe, can make up preprocessing system in case of necessity.Be characterized in S type staggered arrangement filler frame in the body of pond, form the water stream channel of S type, in the filler frame biologic packing material is arranged.So most of sewage passes filler.Small portion sewage can be walked around the filler frame, by the space between filler frame and pool wall, converges with the sewage that passes the filler frame and to enter next filler frame.Microbial film by the multi-stage biological filling surface is handled, and sewage is purified.
This lateral flow biological aerated filter can be divided into three districts: anaerobic zone, aerobic zone, settling region, they are communicated with successively.At anaerobic zone, the sewage percolation is between filler, and the organic pollutant in the sewage obtains anaerobic hydrolysis.At aerobic zone, arrange aerating system in the gap between the filler frame, sewage is aeration aerating in the gap, enter the filler frame then, aerobic bacteria in the microbial film of the both sides of filler frame (along water (flow) direction) plays a leading role, anoxic bacterium in the middle portion microbial film of filler frame plays a leading role, and handles back and forth thus.At aerobic zone, sewage is through oxygenation → aerobic (oxidation, nitrated) → anoxic (denitrification) → oxygenation → aerobic (oxidation, nitrated) ... reaction of high order, not only the carbon source pollutant is well degraded, and can effectively carry out biological denitrificaion and handle.Sewage enters the settling region after degrading by aerobic zone, carries out mud-water separation.
This lateral flow biological aerated filter is to have carried out bold innovation on the basis of existing BAF, compares with existing BAF to have the following advantages:
1. lateral flow biological aerated filter adopts anti-blocking design, and the filler frame loading biologic packing material with customization is arranged in the filter ditch by the S type, and most of sewage passes the filler frame, and small portion sewage is walked around the filler frame by the space between filler frame and pool wall.The engineering construction requirement is mainly considered in space between filler frame and pool wall, considers the relation of water amount and treatment effect simultaneously.Behind long-play, after the accumulation of the microbial film of filling surface is thick, the corresponding increase of resistance meeting in the filler, the filler frame that sewage can be walked around the front enters next filler frame, and all fillers can effectively utilize in the filter tank like this.Simultaneously, because the filler frame relatively approaches (general 200～500mm is wide), the aged microbial film of filling surface can come off by nature, or in aeration process, because of hydraulic disturbance comes off.These microbial films that come off can enter the settling tank precipitation with current, can not stockpile in a large number in filler down, have therefore solved the filter tank blockage problem effectively.And stockpile a small amount of microbial film of getting off, and can be used as the carrier of microorganism growth, strengthened the biomass of whole reactor.Test and actual engineering operation the chamber by experiment, and this lateral flow biological aerated filter only needs each year, and cleaning gets final product for one time to filler.Can save the back-purge system of complex and expensive like this, make operational management also very simple.
2. divided anaerobic zone, aerobic zone, settling region in same biological filter, it is close-coupled processing that sewage is obtained.Prior biological filter tank or be anaerobic filter, or be aerobic filter tank do not have a kind of can be implemented in both to carry out anaerobic treatment in the filter tank, carries out aerobic treatment again.And lateral flow biological aerated filter can be implemented in and finishes anaerobic and aerobic reactions in the same filter tank, make operational management very simple, and sewage by the biological filter, can guarantee higher reactor volume effective rate of utilization and treatment effect preferably with the plug-flow attitude.
3. between aerobic zone filler frame, arrange aerating system, make sewage under the situation that does not need internal reflux, realize multistage aerobic, hypoxia response, reach the effect of nitration denitrification.Description of drawings

Embodiment
Referring to Fig. 1,2,3 and Fig. 4, this lateral flow biological aerated filter has pond body 7, and body 7 one sides in pond have water inlet pipe 1, and opposite side has rising pipe 6.Be divided into three districts in the filter tank: anterior for anaerobic zone, middle part are that aerobic zone, rear portion are the settling region, they are communicated with successively.All press S type staggered arrangement filler frame 2 in each district, biologic packing material 3 is arranged in the filler frame.Arrange the aerating system of forming by aeration head 4 and aerating pipelines 5 between the filler frame in aerobic zone, settling region.
