Abstract
The utility model discloses an oxidation ditch. The oxidation ditch is characterized by comprising an ear-shaped anaerobic zone, an anoxic zone, an aerobic zone and a settling zone which are sequentially inwards and annularly arranged and are communicated with one another, wherein the anaerobic zone is provided with a sewage inlet pipe; a plurality of submerged current thrusters are respectively arranged in the anaerobic zone, the anoxic zone and the aerobic zone; and a plurality of aerator pipes are arranged in the aerobic zone, and a mud discharge pipe and a water outlet pipe are arranged in the settling zone. The utility model aims at overcoming the defects of the prior art and provides the oxidation ditch which has simple structure and good A2O (Anaerobic-Anoxic-Oxic)-precipitation integrated treatment effect.
Description
Technical field
The utility model relates to a kind of oxidation ditch, designs a kind of integrated A especially
2-O oxidation ditch.
Background technology
A
2The O method claims the AAO method again, is the abbreviation anaerobic-anoxic-aerobic method of English first letter of Anaerobic-Anoxic-Oxic, is a kind of sewage treatment process commonly used.The existing integrated A that is used for
2The oxidation ditch structure of O sewage disposal is relatively complicated, and its treatment effect is undesirable.
The utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, to provide a kind of simple in structure, A
2O and the good oxidation ditch of precipitation integral treatment effect.
In order to achieve the above object, the utility model adopts following scheme:
A kind of oxidation ditch, anaerobic zone, the oxygen-starved area of the ear type that it is characterized in that comprising inwardly annular successively setting and be interconnected, aerobic zone and settling region, be provided with sewage water inlet pipe at described anaerobic zone, in described anaerobic zone, oxygen-starved area and aerobic zone, be respectively equipped with a plurality of diving impellers, in described aerobic zone, be provided with a plurality of aeration tubes, in described settling region, be provided with shore pipe and rising pipe.
Aforesaid a kind of oxidation ditch is characterized in that being provided with a rotation weir gate between described oxygen-starved area and aerobic zone.
Aforesaid a kind of oxidation ditch is characterized in that its ingress of described shore pipe is arranged near on the position at center, settling region.
Aforesaid a kind of oxidation ditch is characterized in that the import of described rising pipe is arranged on the position of close aerobic zone and settling region handing-over.
Aforesaid a kind of oxidation ditch is characterized in that the central point of described scraping and sucking machine is arranged on the home position of settling region.
In sum, the utility model with respect to its beneficial effect of prior art is:
Inwardly annular successively anaerobism, oxygen-starved area, aerobic zone and the settling region that is provided with and is interconnected of the utility model oxidation ditch, the diving impeller is set respectively in anaerobism, oxygen-starved area and aerobic zone, so that sewage turns round in anaerobism, oxygen-starved area and aerobic zone, in aerobic zone, be provided with a plurality of micropore aeration pipes, effectively the sewage in aerobic zone adds enough oxygen, the utility model integrated A simple in structure
2O oxidation ditch treatment effect is good.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further described:
A kind of integrated A as shown in Figure 1
2The oxidation ditch of O, comprise that inside successively annular is provided with the anaerobic zone 1 of ear type, and the oxygen-starved area 2 that is interconnected, aerobic zone 3 and settling region 4, be provided with sewage water inlet pipe 5 at described anaerobic zone 1, in described anaerobic zone 1, oxygen-starved area 2 and aerobic zone 3, be respectively equipped with a plurality of diving impellers 6, in described aerobic zone 3, be provided with a plurality of aeration tubes 7, in described settling region 4, be provided with shore pipe 8 and rising pipe 9 and scrape suction mud 10.
Between described oxygen-starved area 2 and aerobic zone 3, be provided with a plurality of swirling recirculation flow weir gates 11 in the utility model.Described shore pipe 8 its ingresss are arranged near on the position at 4 centers, settling region.The import of described rising pipe 9 is arranged on the position that joins near aerobic zone 3 and settling region 4.Described scraping and sucking machine 10 central points are arranged on the center of circle of settling region 4.
