Abstract
Sludge reflux or nitrification liquid backflow air-lift device, belong to technical field of sewage, are the improvement to Sludge in Sewage Treatment backflow and nitrification liquid backflow.Stripping reflux is used in sludge reflux area and nitrification liquid recirculating zone, instead of traditional sludge pump reflux, operating cost can be saved.
Description
Technical field
The invention belongs to technical field of sewage, is a kind of low sludge reflux of energy consumption or nitrification liquid backflow lifting device.
Background technology
Municipal wastewater treatment plant denitrogenation dephosphorizing handling process largely uses A2/ O methods or A/O methods.Generally, for sludge reflux
Flowed back with digestive juice, problems be present：Bad processing in mixed-liquor return mode engineering, with pump reflux, then power consumption is high.To protect
Certain denitrogenation dephosphorizing efficiency is demonstrate,proved, return current ratio of the mixed liquid is often very big, mixed-liquor return of 1-4 times equivalent to amount of inlet water, such as
Fruit sewage plant is larger, and if mixed-liquor return uses pump reflux, power consumption is very big.
The content of the invention
The present invention is precisely in order to overcome above-mentioned deficiency, there is provided the sludge reflux or nitrification that a kind of energy consumption is low, air lift effect is good
Liquid backflow air-lift device.
To realize the object of the invention, there is provided following technical scheme：Sludge reflux and nitrification liquid backflow air-lift device, including
Blower fan, the air lift pipeline being connected with blower fan, it is characterised in that the air lift pipeline includes some branch pipes and supervisor, the branch
Manage as annular, stagger setting, each branch pipe connects each branch pipe with supervisor up and down, supervisor's connecting fan, on the branch pipe
Surface offers the air lift hole being intervally arranged, and air lift nozzle is connected with the air lift hole, and air lift nozzle includes the taper at both ends
Section and the compression section of centre, conical section maximum diameter of hole are 3 with intermediate compression section aperture ratio：1.
Preferably, the branch diameter is 1 with supervisor's caliber ratio:2~3.
Beneficial effect of the present invention：By the process operation of device, reach the requirement of sludge reflux or nitrification liquid backflow, significantly
Energy consumption is saved.Main innovation is：Pump reflux is replaced by air-lift device backflow.Specific implementation situation is as follows：For mixed liquor
Backflow is flowed back using air- extraction, and this is maximum bright spot of the invention.In A2In/O techniques, in terms of mixed-liquor return includes 2, one
It is that the sludge reflux of second pond carries out recycling again to anaerobic zone, second, the nitrification liquid of aerobic zone is back to anoxic
Area.Either sludge reflux or nitrification liquid backflow, the amount of the mixed liquor of backflow is all very huge, if using traditional
With pump reflux, it will the very big electric energy of consumption, using air- extraction returned sludge or nitrification liquid, only need blower fan to provide a seldom part
Air quantity, you can reach the purpose of mixed-liquor return, be greatly saved electric energy, the present apparatus is had using air-lift device backflow mixed liquor
There is good economic benefit.
