Description
Technical field
The invention belongs to Aeration tank slope in equipment for sewage treatment technology, more particularly to a kind of Biolak sewage treatment process
Portable aerator.
Background technology
Biolak sewage treatment process (BIOLAK) technology is in twentieth century 70 years by German Feng Nuodunxi companies
A kind of successful Novel sewage treatment technology of generation research, and formally put into operation first BIOLAK process sewage in nineteen eighty-three
Treatment plant.Being unique in that using underload activated sludge process for it, produces one kind by a kind of floating aerating chain
Awave mixed oxidization effect, so as to create the good growing environment of all kinds of extraordinary microorganisms, what realization was higher denitrogenates phosphorus
Effect.Common BIOLAK process flow process：Dephosphorization pond Aeration tank (multistage A/O functions) sedimentation tank depositing reservoir is up to standard outer
Row.Wherein, dephosphorization pond：Sewage enters the pond together with returned sludge, is sufficiently mixed, then enters aeration zone under agitator effect.It is dirty
There is the reaction of part hydrolysis acidification in Shui Gai areas, improve the biodegradability of sewage, mitigate the burden of follow-up aeration zone, so as to reduce
Power consumption and the volume of aeration zone.The extended aeration of mixed zone and aerobic treatment region is engaged, can to the denitrogenation dephosphorizing of sewage
Play effect well；Sedimentation tank：Sewage solid-liquid separation in clarification sedimentation tank, the sludge for being deposited in bottom are suspended formula suction mud
Device is suctioned out, and a sludge part is back to Aeration tank, and a part is beaten to homogeneous pond, dehydration by residual sludge pump.Aerator is
Important component part in sewage disposal process by activated sludge process system, by aerator to Aeration tank oxygen supply, while aeration
The function that equipment is also mixed, to strengthen mass transfer condition of the pollutant in water treatment system, improves treatment effect.Aeration
Pond：Aerator is that micropore sleeve pipe swings aeration form, and it is some side by side by main pipe that aerator structure is generally aerator
Root snorkel, the snorkel draw float tube (aeration tube) by flexible pipe, and float tube is suspended in pond, is provided with some little in float tube
Hole, aperture connection flexible pipe, flexible pipe are connected with aerator.During ventilation, aeration tube produces motion in water due to unbalance stress.Due to
The operation of aerator, rising bubble form air supporting, and movement locus increase the dead time that gas ducks in drink, therefore improve oxygen
Utilization rate.Aeration tank upper end size：74.9m×72.1m；Lower end size：74.9m×56.5m；Chi Shen：5m, Aeration tank both ends of the surface
For the slope of 33.3 ° of slope angles, two sides are concrete face wall.The slope and bottom are covered with HDPE antiseepage film, and antiseepage film is not
Can contact with sharppointed article, it is easily damaged, then subsoil water can be made to rise in Aeration tank.Biolak sewage treatment process can not be clear
Empty Aeration tank is removed contamination, in case bottom HDPE antiseepage film is excessive by groundwater pressure and floats.
At present, the problem of Biolak sewage treatment process Aeration tank presence is：Due to the slope angle on Aeration tank slope it is larger, and
Aerator is not provided with directly over slope, causes activated sludge to deposit on the slope, make Aeration tank dischargeable capacity less and less, and it is dirty
Large stretch of mud scum is formed after mud alluvial anaerobism, water outlet indices are impacted.Biolak sewage treatment process Aeration tank slope
Sludge alluvial problem, is sewage treatment plant's technical barrier urgently to be resolved hurrily.

The present invention for achieving the above object, is employed the following technical solutions：Aeration tank in a kind of Biolak sewage treatment process
The portable aerator on slope, including some snorkels, the aeration tube drawn by flexible pipe with snorkel, is opened on aeration tube
There are some apertures, aperture connection flexible pipe, flexible pipe are connected with aerator, be it is characterized in that：On the snorkel, bypass is connected with movement
Formula aerator, the portable aerator are placed in Aeration tank slope and bottom intersection, the portable aerator bag
Inducing QI steel pipe and underwater aerator is included, described inducing QI steel pipe one end is connected with snorkel by resistance to compression flexible pipe, its other end and water
Lower aerator connection, the underwater aerator are provided with some apertures of supplying gas.
The inducing QI steel pipe is vertical with underwater aerator affixed, and the inducing QI steel pipe is fixed in the central position of underwater aerator
Put.
Ball valve is provided between the inducing QI steel pipe and snorkel.
The underwater aerator two ends are equipped with rubber wheel, and underwater aerator is provided with some apertures of supplying gas.
The portable aerator is corresponded with some snorkels and is arranged.
The portable aerator is respectively placed in Aeration tank both ends of the surface slope and bottom intersection.
Beneficial effect：Compared with prior art, the present invention is constantly overflowed by compressed air in underwater aerator, stirs water
Stream, thoroughly solve the phenomenon of sludge alluvial on the Aeration tank slope of Biolak sewage disposal, it is ensured that Biolak Aeration tank has
Effect volume and effluent quality qualified discharge；Underwater aerator two ends are equipped with rubber wheel, are easy to movement, while can effectively prevent sharp
Thing and HDPE antiseepage film directly contacts, can be prevented effectively from the damage of HDPE antiseepage film.
