Abstract
The utility model discloses a concentric nested active oxidation ditch, comprising an OCO continuous traveling reaction tank composed of an anaerobic area, an anoxic area and an aerobic area, and a sedimentary basin, wherein the sedimentary basin is annularly disposed on the edge of the aerobic area of the continuous traveling reaction tank, and the lower part of the sedimentary basin is communicated with the continuous traveling reaction tank. The utility model has the advantages of saving energy consumption and being convenient for the circumfluence utilizing of the active sludge.
Description
Technical field
The utility model belongs to the environment protection sewage treatment unit and makes the field.
Background technology
The aeration of continuously belt reaction tank formula (OCO) sewage disposal oxidation ditch purifies between oxidation ditch and settling bowl and sets up respectively, and it is big to exist floor space, and mud refluxes and consumes the shortcoming of additional energy source.
The purpose of this utility model is under the prerequisite of guaranteeing other advantage of OCO sewage disposal, designs a kind of more good structure formation, and it is more compact to make it to have structure, the advantage that floor space is little and energy consumption is more saved.
The purpose of this utility model is to realize by following design.
Summary of the invention
Form nested active oxidation ditch by the belt continuously reaction tank of OCO that anaerobic zone, oxygen-starved area and aerobic zone constitute with settling bowl, the settling bowl annular is arranged on the edge of the reaction tank aerobic zone that goes in ring continuously, and the settling bowl bottom communicates with the reaction tank that goes in ring continuously.
Compare with existing spirit, the utlity model has the saving energy consumption, be convenient to the advantage that activity sludge reflux utilizes.
Description of drawings
Fig. 1 is a structure vertical view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the part sectioned view of settling bowl edge portion.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Among Fig. 1 and Fig. 2,1 is the tubular anaerobic zone, and 2 is the oxygen-starved area dividing plate, and 3 is the aerobic zone dividing plate, and 5 is sewage water inlet pipe, and 6 is water outlet, and 7 is the negative area dividing plate, and settling bowl 4 annulars are arranged on the edge of the reaction tank aerobic zone that goes in ring continuously.Can see that in conjunction with Fig. 3 the settling bowl bottom communicates with the reaction tank that goes in ring continuously, 8 settlement separators for the ring-type setting, it is made of several the settlement separate plates around the settling bowl setting, and the angle of declination α of settlement separate plate is arranged on the 55-65 degree and is advisable.
For ease of different steps in oxidation ditch liquid stream recycle ratio is regulated according to biochemical reaction, be provided with the flow deflector 9 that is used to regulate the current parameter in the continuously belt reaction tank, flow deflector can be done the rotation of certain angle around axle 10, so that fluidic current parameter changes, thus regulator solution stream recycle ratio.
Experiment shows, oxygen-starved area dividing plate 2, aerobic zone dividing plate 3 are not made semicircle and when making the structure with sweep angle β, oxidation ditch has more good hydromechanics environment, and energy consumption reduces.Generally speaking, be advisable about 20 degree in this sweep angle.
Claims (3)
1, nested, concentric active oxidation ditch, form by belt continuously reaction tank of the OCO that constitutes by anaerobic zone, oxygen-starved area and aerobic zone and settling bowl, it is characterized in that the settling bowl annular is arranged on the edge of the reaction tank aerobic zone that goes in ring continuously, the settling bowl bottom communicates with the reaction tank that goes in ring continuously.
2, according to the described nested, concentric active oxidation of claim 1 ditch, it is characterized in that, be provided with the flow deflector that is used to regulate the current parameter in the reaction tank that goes in ring continuously.
3, nested, concentric active oxidation ditch according to claim 1 and 2 is characterized in that, oxygen-starved area dividing plate (2), aerobic zone dividing plate (3) have sweep angle β in the reaction tank that goes in ring continuously.
