Description
Technical field
The utility model relates to a kind of middle water reuse advanced treatment apparatus, is specifically related to a kind of macropore filler in aerated biologic filter pool.
Background technology
Water reuse advanced treatment generally adopts BAF at present.BAF is called for short BAF, be the end of the eighties at a kind of new bio embrane method waste disposal plant that the America and Europe grows up, obtain large development the beginning of the nineties.BAF integrates bio-oxidation and holds back suspended solids; Saved post precipitation pond (second pond); The maximum processing scale reaches the hundreds of thousands of tpd, and has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX (objectionable impurities).Yet adopt traditional BAF to dispose of sewage, have that filler be prone to stop up, shortcomings such as back flushing is frequent, working cost height.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of macropore filler in aerated biologic filter pool.
Its technical solution is:
A kind of macropore filler in aerated biologic filter pool; Comprise pond, filter tank body, the set inside of body is equipped with the biological respinse filtering layer of organic macropore filtrate in the pond, filter tank, below the biological respinse filtering layer, supporting layer is set; The water distribution filter that is connected with water inlet pipe is set above the body of pond, filter tank; One side of body connects the clear water rising pipe in the pond, filter tank, and the bottom of body is provided with perforated pipe, back flushing gas distribution pipe and the back flushing water distribution branch pipe that is used for aeration in the pond, filter tank, and the back flushing gas distribution pipe is connected with the back flushing inlet pipe; The back flushing water distribution branch pipe is connected with the back flushing water inlet pipe, and one side of body connects the back flushing water shoot in the pond, filter tank.
Further, the water-in of water inlet pipe is communicated with distributing water room, and distributing water room is communicated with the water outlet of water inlet manifold, and dividing plate is set in distributing water room.
The useful technique effect of the utility model is:
The utility model can prevent effectively that the biological respinse filtering layer from stopping up, and has that treatment effect is good, the back flushing number of times is few, simple to operate, working cost low and advantage such as GWR is little.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the longitdinal cross-section diagram of the utility model.
Among the figure: the body of pond, 1-filter tank; 2-biological respinse filtering layer; The 3-supporting layer; 4-water distribution filter; The 5-water inlet pipe; 6-distributing water room; The 7-dividing plate; The 8-water inlet manifold; 9-clear water rising pipe; The 10-perforated pipe; 11-back flushing inlet pipe; 12-back flushing water inlet pipe; 13-back flushing water shoot.
Embodiment
In conjunction with accompanying drawing, a kind of macropore filler in aerated biologic filter pool comprises pond, square filter tank body 1; The set inside biological respinse filtering layer 2 of body 1 is equipped with organic macropore filtrate in the biological respinse filtering layer 2 in the pond, filter tank, and this filter material surface is coarse; High-concentration biological film easily adheres to, grows; This microbial film is not limited by mud age, and kind is abundant, and different filtering layer sections can both form the dominant species that adapts with this section water quality naturally.Supporting layer 3 is set below biological respinse filtering layer 2, and supporting layer 3 is piled up by pebbles and is formed, in order to support biological respinse filtering layer 2.A plurality of water distribution filters 4 are set above pond, filter tank body 1, and water distribution filter 4 is connected with water inlet pipe 5.The water-in of water inlet pipe 5 is communicated with a side of distributing water room 6, and dividing plate 7 is set in distributing water room 6, and the opposite side of distributing water room 6 is connected with water inlet manifold 8, and the water-in of water inlet manifold 8 connects pretreatment pool.One side of body 1 connects clear water rising pipe 9 in the pond, filter tank, carries out monolateral water outlet, also can take the clean water after the mode of peripheral effluent is discharged filtration certainly.The bottom of body 1 is provided with perforated pipe 10, back flushing gas distribution pipe and the back flushing water distribution branch pipe that is used for aeration in the pond, filter tank; The back flushing gas distribution pipe is connected with back flushing inlet pipe 11; The back flushing water distribution branch pipe is connected with back flushing water inlet pipe 12, and one side of body 1 connects back flushing water shoot 13 in the pond, filter tank.
Sewage after the primary treatment flows in the distributing water room through water inlet manifold; When water level rises to certain altitude; Sewage in the distributing water room flows in the body of pond, filter tank through water inlet pipe and the water distribution filter that is connected with water inlet pipe; And filter through the biological respinse filtering layer, the clean water after the filtration flows out reuse through the clear water rising pipe.When the biological respinse filtering layer is handled sewage, carry out aeration, for microorganism growth provides oxygen through perforated pipe.In the filtering layer section near the sewage layer, organic concentration is high, and the heterotrophism flora is preponderated; Most of BOD obtains degraded at this, and in the filtering layer deep, the inhibition that autotrophic bacterias such as nitrifier are not produced by organic concentration and heterotrophic bacterium; Become dominant bacteria, have good digestion.
Along with the carrying out of treating processes, the suspended substance of tackling in the biological respinse filtering layer is on the increase, adherent microbial film progressive additive on the filter material surface; Space in the biological respinse filtering layer progressively gets clogged; Head loss increases thereupon, reaches the maximum head loss that allows, and need carry out back flushing.Back flushing adopts air water to unite flushing.The back flushing air gets into back flushing air gas distribution pipe by the back flushing inlet pipe, gets into the biological respinse filtering layer equably, makes to stick to the lip-deep large number of biological film of filtering material particle and peeled off.Carry out combined water and air backwash subsequently; Backwashing water gets into water distribution branch pipe by the back flushing water inlet pipe, with the form entering biological respinse filtering layer of big resistance water distribution, under the air water acting in conjunction; Filter material layer produces loosening; And slightly expand, make aged microbial film, suspended impurity take filtering layer out of with current, last water is rinsed filtering layer well.Backwashing wastewater is discharged outside the pond after collecting through the discharge of back flushing water shoot and by sk-.
Pond, above-mentioned filter tank body can be arranged side by side a plurality of, shared each other water distribution system, gas distribution system and back-purge system.
The part of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that under the instruction of this specification sheets, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of the utility model.
