Description
Technical field
The present invention relates to a kind of wastewater treatment pond, particularly a kind of eddy current fixation of microbe aeration tank.
Background technology
The sewage Activated Sludge Process is a kind of sewage treatment process of using always; This technology is through evenly arranging air-diffuser to pond body bottom; Air-diffuser is mainly used in provides biological sewage treatment required oxygen, and air-diffuser is uniformly distributed with fully in this processing requirement pond body, and will use special-purpose aeration head; Or aeration tube release gas, mixed solution is the mixed solution of mud and water in the pond.Sludge loading is lower, and volume big investment in required pond is high under the same terms.
The WWT fluidization is another kind of sewage treatment process commonly used; This technology is evenly arranged air-diffuser through pond body bottom; Air-diffuser is mainly used in to be provided the required oxygen of biological sewage treatment and makes filler formation fluidized state in the pond; Mixed solution is with complete blended mode in the pond, does not form the fluid vortex state in the pond, and volume big investment in required pond is high under the same terms.
Summary of the invention
The object of the invention is exactly deficiency and the shortcoming that will eliminate above-mentioned prior art, and a kind of eddy current fixation of microbe aeration tank is provided, problem such as can solve that treatment process technical sophistication in sewage and the wastewater treatment process, floor space are big, investment height and sludge loading are low.
In order to achieve the above object; The invention provides a kind of eddy current fixation of microbe aeration tank and comprise aeration tank, water inlet pipe, aerating apparatus, discharging device and mikrobe aeration tank filler; Water inlet pipe and discharging device are installed in the aeration tank sidewall; Bottom, said aeration tank is divided into aeration zone and buffer zone, aeration zone and buffering interval at a distance from or dentation be crisscross arranged, the aeration zone accounts for pond floorage 30% ~ 50%; Said aerating apparatus comprises inlet pipe and aeration parts, and aeration members inlet pipe is laid on the aeration zone.
The aeration parts of said aerating apparatus are preferably the herring-bone form aeration tube.
When said aeration zone and buffer zone were provided with for the interval, the buffer zone width was 50% ~ 100% of aeration zone.
Said aeration zone and buffer zone can be dentation and are crisscross arranged.
Said mikrobe aeration tank filler is the aeration tank filler of attached biological film, is suspended state in the aeration tank during water-filling.
Said discharging device comprises effluent collector and rising pipe, and effluent collector is the perforate tubular structure, and the perforate direction is the radial direction of pipe, and the perforate ratio is at 30% ~ 50% of body, and rising pipe is positioned at the effluent collector middle part.
Beneficial effect of the present invention:
