Description
Technical field
The utility model relates to a kind of biological contact oxidation pond for the treatment of sewage such as industry, lives, belongs to sewage disposal technologyField.
Background technology
Biological contact oxidation pond is the center processing structures of biological contact oxidation process equipment therefor. Biological contact oxidation process refers toSoftware filler (as biomembranous carrier) is set in aeration tank, when through the waste water of oxygenation with certain flow velocity flow through filler withBiomembrane contact, the method for utilizing the synergy of biomembrane and suspension Microbial Communities in Activated Sludge to purify waste water. Biological contact oxidationThe processing that change method can be applicable to, all obtains good benefit. Meanwhile, because this technique has, structures are simple, maintenance management sideJust, do not need sludge reflux, do not produce sludge bulking, the series of advantages such as running operation is more flexible, thereby be widely usedIn the sewage disposal system of all trades and professions. Biological contact oxidation pond is divided into shunting and two kinds of pond types of single flow.
In shunting biological contact oxidation pond, it is in different compartments, to carry out respectively that waste water oxygenation contacts with filler from sewage. ?Oxygenation compartment carries out violent aeration aerating; At the contact compartment of filling material, the sewage filler of flowing through downwards, is beneficial to biological growth.But in the type of this pond, sewage flows slow between filler, and biomembrane upgrades slow, easily stops up.
In single flow biological contact oxidation pond, directly at filler bottom blast aeration, thereby produce up-flow upwards in packing area,Biomembrane is subject to ascending current and airflow scouring, comes off and upgrades soon, active good. But traditional single flow biological contact oxidation pond is depositedIn equipment relative complex, the drawback of taking up an area that space is large, disposal ability is low, water outlet is muddy etc.
Summary of the invention
The deficiencies such as the disposal ability that exists for existing biological contact oxidation pond is low, water outlet is muddy, the holdup time is long, this practicality newlyType provides a kind of can significantly improve cleaning water, effectively avoid the enhanced type single flow biological contact oxidation pond of water outlet muddiness.
Enhanced type single flow biological contact oxidation pond of the present utility model, adopts following technical proposals:
This oxidation pond, comprises pond body, and the cross section of pond body is rectangular, and length-width ratio is 1:1-2:1, in the body of pond from the bottom to top successivelyFor aeration zone, packing layer and steady water layer, the ratio of the height of aeration zone, packing layer and steady water layer is 1:4:1.2; The outside of pond bodyIn aeration zone, place is provided with water inlet pipe, and at steady water layer, place is provided with drainpipe, and the bottom of pond body is provided with blow-off pipe; In aeration zoneBe provided with aerator; In packing layer, be provided with the stuffing frame being fixed on the body inwall of pond, on stuffing frame, be hung with filler; Steady water layerIn be provided with the plant growing frame being fixed on the body inwall of pond.
Described plant growing frame is the rope type support of being knitted by rope, or plantation dish-type support.
The utlity model has following characteristics:
1. carry out plant strengthening, strengthened wastewater purifying efficiency.
2. due to the adsorption cleaning of top plant, can significantly reduce water outlet SS, avoid water outlet muddiness.
3. adopt fibre bundle combination filler, overcome the shortcomings such as the easy conglomeration of conventional filler, have that specific surface is large, easy to be filmed, be difficult for knotThe advantages such as group, bubble cutting performance is good.
4. reduce the sewage holdup time, improve purification efficiency.
5. effectively reduce contact-oxidation pool progression, wherein in enhanced type single flow biological contact oxidation pond, can save sedimentation basin. FromAnd occupation of land space is little, operation maintenance is convenient, and investment and operating cost are low.

Detailed description of the invention
Embodiment 1
The enhanced type single flow biological contact oxidation pond of the present embodiment, its structure as depicted in figs. 1 and 2, comprises by concrete and buildingThe pond body 1 becoming, the cross section of pond body 1 is rectangular, and length-width ratio is 1:1-2:1, determines according to actual conditions, and available depth is4.4m-4.9m. In pond body 1, be followed successively by from the bottom to top aeration zone, packing layer and steady water layer, aeration zone, packing layer and steady water layerThe ratio of height be about 1:4:1.2, confirm through lot of experiments, this ratio can make the utility model obtain best purification placeReason effect. The outside of pond body 1 is provided with water inlet pipe 6 at aeration zone place, and the outside of pond body 1 is provided with drainpipe at steady water layer place7, the bottom of pond body 1 is provided with blow-off pipe 8.
