Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of the Sewage treatment systems that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of the utility model protection.
As Fig. 1, the utility model embodiment provides a kind of Sewage treatment systems, comprise the multiple biological filter and a settling tank 7 that arrange from top to bottom, described settling tank 7 is positioned at the below of biological filter, bio-carrier 3 and at least one siphon pipe 2 is equipped with in biological filter described in each, described siphon pipe 2 is in inverted U-shaped structure, its one end is water-in, the other end is water outlet, described water-in is arranged near the bottom of described biological filter, thus to discharge the sewage in biological filter to greatest extent, described water outlet is positioned at the below of this biological filter; The vertex of described siphon pipe 2 is positioned under the design liquid level 1 of described biological filter.
As Fig. 1, wherein, described bio-carrier 3 is the protruded packing for biofilm development, and described protruded packing is filled in described biological filter.The porosity of described protruded packing is greater than 40%.
As Fig. 1, in this preferred embodiment, the quantity of described biological filter is three, is followed successively by high-rise filter tank 4, filter tank, middle level 5 and low layer filter tank 6 from top to bottom.The water outlet of the siphon pipe 2 in described high-rise filter tank 4 is positioned at directly over filter tank, described middle level 5, the water outlet of the siphon pipe 2 in filter tank, described middle level 5 is positioned at directly over described low layer filter tank 6, and the water outlet of the siphon pipe 2 in described low layer filter tank 6 is positioned at directly over described settling tank 7.In other embodiments, the quantity of described biological filter can be two, also can be more than three, specifically depend on the circumstances.
As Fig. 1, when described high-rise filter tank 4 sewage progressively fills the vertex exceeding siphon pipe 2, siphonage will be there is, sewage through preliminary biological respinse in high-rise filter tank 4 is entered rapidly filter tank, middle level 5, when after the whole emptying of sewage, along with air enters siphon pipe 2, siphonage stops, and 4, higher level filter tank enters " aeration " process.Filter tank, middle level 5 has the structure same with high-rise filter tank 4, along with entering of sewage, repeats the treating processes in high-rise filter tank 4, and sewage is entered again low layer filter tank 6 till water quality reaches standard.Finally, sewage is entered settling tank 7 and precipitate, just complete whole treating processes.When the microbial film porosity of filler in biological filter and generation is greater than 40%, the generation of syphonic effect just can not be affected.As long as the flow of control siphon pipe 2, quantity and height, the speed circulated of carrying out a biological disposal upon can be controlled; Because in filter tank, sewage level is significantly elevated, oxygenizement is abundant, and oxygen in water increases severely, and biochemical action is remarkable; Again because draining is rapid, can promote that aging microbial film is peeled off and taken away by flowing water.
As Fig. 1, in addition, the bottom of described settling tank 7 is provided with water port 8, and described water port 8 place is provided with by-pass valve control.The end of described water port 8 is provided with filtration unit, for filtering, only can discharge water and not sediment exclusion.
In another embodiment, described bio-carrier 3 is ribbon-like fibre felt packing, it comprises base layer and layer of fibers, described base layer is EVA material, layer of fibers is polypropylene fibre wire material, and described fibrolaminar polypropylene filaments adopts knitting mode Stagger-wrap to be fixed on base layer and forms ribbon-like fibre felt.The width of the banded fibrefelt of wall scroll is 8 ~ 12cm, and this width value is the test and the engineering reality that have considered the aspects such as auxiliary water distribution, turbulent closure scheme, head loss, engineering design, meets the needs of desired width value.Ribbon-like fibre felt total thickness is 12mm ± 2mm, and base layer thickness is 4mm ± 1mm, and fiber layer thickness is 4mm ± 1mm.During use, be polymerized some ribbon fibrefelts louvered zoology.In the present embodiment, as required some fibrefelt fillers are made on polypropylene rope, form louvered zoology.Described zoology is when engineering operation, for the microbial population of breeding in anaerobism, anoxic, aerobic environment directly provides anaerobism, anoxic, aerobic region, when the microbial metabolism of different zones upgrades, the microbial reaction product of adjacent area can be utilized mutually, make pollutent can thoroughly, continuous degradation.The bio-carrier 3 of the present embodiment has huge specific surface area, and every cubic metre can provide the biological attachment area up to 50000 square metres, far above other catalytic oxidation filler that can be applied to now engineering reality.The material of the bio-carrier 3 of the present embodiment is polymer inert material, and normal service life is more than 10 years.
In sum, first sewage be injected into top biological filter, start biochemical reaction simultaneously, when liquid level is higher than siphonal vertex, siphonage produces, rapidly sewage is entered biological filter next time, when top biological filter continue to accept sewage carry out new biochemical reaction time, the biological filter of lower one deck then starts the process occurred in the biological filter of repetition last layer; Sewage drains into the biological filter of lowermost layer under continuing, until settling tank just completes whole process.Described Sewage treatment systems structure is simple, and with low cost, energy consumption is humble.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
