Background technology
Currently, in recycled writing paper paper industry, as policy, economy and the triple requirements of environmental protection, enterprise all need to implement cleaning
Production, energy-saving and emission-reduction produce the pollutant concentration Gao Te of waste water as waste paper and mthod of white water from paper making cyclic utilization rate are higher and higher
It is not that calcium ion content significantly rises in water, the high water quality of calcium ion content enters anaerobic system, causes anaerobic grain sludge calcium
Change so that Anaerobic Treatment ability declines；The high water quality of calcium ion content enters aerobic system, and is precipitated in aerobic system, shape
At incrustation scale, entire aerobic system aeration quality is caused to decline.If anaerobic system removal rate is poor, aerobic system processing capacity is poor, most
Entire sewerage is caused to be collapsed eventually.
Current existing efflux aerator easily blocks, and cleaning difficulty is big, influences whether entire preaeration jet-flow aeration
The operation of system causes follow-up anaerobism, aerobic calcium ion content high and fouling.
Utility model content
The purpose of this utility model be to provide it is a kind of easily implement, Operation and Maintenance it is simple, be not required to stoppage in transit preaeration jet-flow aeration
System can handle the efflux aerator blocked, not influence follow-up anaerobism, the preaeration jet-flow aeration that aerobic stage is run
System.
The technical solution of the utility model is：A kind of preaeration jet-flow aeration system is provided, including preaeration fills body, it is described
Preaeration fills body side surface and is surrounded with jet stream supervisor and air hose supervisor, and the preaeration fills body upper side and is equipped with pipeline and jet stream master
Pipe is connected, and the preaeration fills and jet pump, the preaeration are housed on the pipeline between body upper side and jet stream supervisor
Jet-flow aeration system further includes several independent jet-flow aeration units, each jet-flow aeration unit and jet stream supervisor, wind
Pipe supervisor, preaeration fill body and are connected by pipeline.
Preferably, the jet-flow aeration unit includes the jet stream branch pipe communicated with jet stream supervisor, is welded on jet stream branch pipe
Lap joint flange, the jet vectoring valve being arranged on jet stream branch pipe, with air hose supervisor communicate air hose branch pipe, be welded on air hose branch
Lap joint flange on pipe, volume control damper, one end and the air hose branch pipe and jet stream branch pipe being arranged on air hose branch pipe are homogeneous
Even, the other end connects jet-flow aeration pipe by elbow and fills the jet aerator that body is connected, the jet-flow aeration with the preaeration
It is welded with lap joint flange on pipe and jet-flow aeration control valve is installed.
Preferably, the air hose supervisor is connected with air blower.
Preferably, the front end of the jet-flow aeration pipe is equipped with nozzle, and the nozzle is located at the preaeration and fills internal subordinate
End.
Preferably, the diameter of the jet stream supervisor is more than the diameter of the jet stream branch pipe, and the air hose predominant tube diameter is more than
The diameter of the air hose branch pipe.
The beneficial effects of the utility model are：The utility model controls single jet aerator by using single valve
Mode keeps combustion adjustment simpler, and repair is more convenient, strong compared with traditional jet-flow aeration system mounting means controllability
Much.In the case where being not required to stop preaeration jet-flow aeration system operation, the cleaning to jet aerator can be achieved with.
Description of the drawings
Fig. 1 is the utility model preaeration jet-flow aeration system structure diagram.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1, the utility model provides a kind of preaeration jet-flow aeration system, including preaeration fills body 1, described pre-
Aeration fills 1 side surface upper part of body and is surrounded with jet stream supervisor 3 and air hose supervisor 4, the preaeration fill 1 upper side of body be equipped with pipeline with
Jet stream supervisor 3 is connected, and the preaeration fills and jet pump 2 is housed on the pipeline between 1 upper side of body and jet stream supervisor 3,
The preaeration jet-flow aeration system further includes several independent jet-flow aeration units, each jet-flow aeration unit with penetrate
