Degradation principles and the feature with high efficiency, low cost, are widely used in high concentration pulping wastewater treatment, wherein internal circulating anaerobic
Tower is using relatively broad.
Inner circulation anaerobic tower in order to obtain waste water and the good mixed effect of anaerobic bacteria (such as granule sludge), be typically designed compared with
High upflow velocity such as 4m/s even more highs, in order to keep the stabilization of fluid bed, prevent the escape of sludge, and common design is higher
Tower body height, such as 16m even more highs.During whole paper-making effluent treating process, the waste water after depth Anaerobic Treatment
Still can not directly it discharge, it is necessary to carry out further biological treatment into Aerobic Process for Treatment system, but general Aerobic Process for Treatment is for exposure
Gas cost and technical feasibility consider that pond height exists certain typically between 6m or so, such anaerobic effluent and aerobic water inlet
Difference in height.Existing technology is to aerobic system by anaerobic tower water outlet directly using discharge of pipes, is the shortcomings that the method：1st, exist
Anaerobic tower outfall drain is easily carried air and enters pipeline, because the turbulence, compression and release of air cause pipeline to shake, causes
Instrument and meter for automation measurement is inaccurate on pipeline or reduces service life；2nd, due to containing calcium ion in waste water, in air
The carbon dioxide contained produces serious fouling by being sufficiently mixed with waste water, in anaerobic tower near exit and draining tube wall and showed
As, or even influence the normal use of equipment；3rd, due to bringing air into anaerobic tower draining, aerobic water inlet is caused to produce more carbon
Sour calcium, Aerobic is caused to be easier scale problems occur.
【Utility model content】
The technical problems to be solved in the utility model be to provide it is simple in construction, safe and reliable, can effectively energy dissipating choke one
Kind is used for waste water advanced anaerobic treatment tower water drainage energy dissipation choke device.
What the purpose of this utility model was realized in：
One kind is used for waste water advanced anaerobic treatment tower water drainage energy dissipation choke device, including depth anaerobic treatment tower and located at institute

Type tubular construction.
One kind as described above is used for waste water advanced anaerobic treatment tower water drainage energy dissipation choke device, the double-U-shaped tubular construction
Including upper transition connection portion and lower transition connection portion, the lower transition connection portion bottom is connected with blow-off pipe, on the blow-off pipe
Provided with blowdown check valve.
One kind as described above is used for waste water advanced anaerobic treatment tower water drainage energy dissipation choke device, and the drainpipe includes upper
Pipeline section and lower tube section, the upper end of the upper pipeline section are connected with the anaerobic effluent mouth, and the lower end of the lower tube section is stretched into described
In Aerobic Process for Treatment tower, the double-U-shaped tubular construction is located between the upper pipeline section and the lower tube section.
One kind as described above is used for waste water advanced anaerobic treatment tower water drainage energy dissipation choke device, the double-U-shaped tubular construction,
Upper pipeline section and lower tube section are integrally formed.
Compared with prior art, the utility model has the following advantages that：
The utility model sets up the draining with double-U-shaped tubular construction by the anaerobic effluent mouth in depth anaerobic treatment tower
Pipe, reach and prevent air from entering anaerobism discharge pipe line and prevent the purpose of mixing and the turbulence of air and water body in pipeline, avoid
Water body compressed air is caused because air enters in discharge pipe line and the delivery port that causes to recoil causes impeded drainage, and is avoided thus
Caused by pipeline vibrations and to caused by pipeline damage.The draining that the utility model had both realized depth anaerobic tower is smooth, subtracts again
Vibrations caused by few air-impingement, also avoid the mixing of air and water body, not only ensure that anaerobic effluent or even entire depth
The stabilization and Efficient Operation of system for anaerobic treatment, the also stable operation for follow-up aerobic system provide good condition.
