Abstract
The invention discloses an integrated A2-O oxidation ditch, which is characterized by comprising an ear-shaped anaerobic zone, an anoxic zone, an aerobic zone and a settling zone, wherein a sewage inlet pipe is arranged in the anaerobic zone; a plurality of submersible water impellers are arranged in each of the anaerobic zone, the anoxic zone and the aerobic zone; a plurality of aeration pipes arranged in the aerobic zone; and a sludge discharge pipe and a water outlet pipe are arranged in the settling zone. The invention aims to provide an A2O and settling integrated oxidation ditch with a simple structure and ideal treatment effect for overcoming the drawbacks of the prior art.
Description
Technical field
The present invention relates to a kind of integrated A
2The oxidation ditch of-O.
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.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, A in order to overcome weak point of the prior art
2O and the good oxidation ditch of precipitation integral treatment effect.
In order to achieve the above object, the present invention adopts following scheme:
A kind of integrated A
2The O 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 integrated A
2The O 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 integrated A
2The O 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 integrated A
2The O 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 integrated A
2The O 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 present invention 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 oxidation ditch of the present invention, 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 present invention's integrated A simple in structure
2O oxidation ditch treatment effect is good.
