In further technical scheme, described air blast is connected with frequency-variable controller.
In further technical scheme, the lateral cross section of described gas-water mixing cavity be shaped as d font.
After said structure, the utility model compared to the prior art advantageously: the utility model structure
Simply, low cost, jet aerator before paper waste conveys to sewage disposal device, in regulating reservoir for its jet aerator
Air Exposure is carried out to paper waste, the process more energy-conserving and environment-protective to paper waste, processing procedure clean environment firendly is pollution-free.
The utility model structure provides the processing function of aeration pretreatment simply by jet aerator to paper waste, leads to
Cross jet aerator to the shearing of air water and jet action, so that the oxygen of in the air is transferred in waste water, improve molten in waste water
Solution oxygen, the propagation of suppression acidification bacteria, prevent waste water to be excessively acidified, improve the freshness of sewage it is therefore prevented that because of acescency and
Acidifying is too high to be changed anaerobic bacteria flora distribution, makes anaerobic bacteria be difficult to the situation with propagation of surviving；And avoid because waste water corruption lead
Cause the sludge fermentation of precipitation in subsequent processing device, impact sedimentation effect and effluent quality；Stirring action can be played again, make to give up
Water homogenisation is beneficial to the stable operation of subsequent processing device, reduces the pressure of processing equipment.
Brief description
With reference to the accompanying drawings and examples the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, regulating reservoir 2, jet aerator 3, jet-flow aeration jet 4, air blast 5, jet pump.
Specific embodiment
Described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model
Enclose.
Embodiment, as shown in Figure 1, a kind of high acescency paper waste pretreatment unit of high concentration, including for storage and
Process regulating reservoir 1 and a jet aerator 2 of paper waste, jet aerator 2 is fixed on the at the bottom of pond of regulating reservoir 1, and jet exposes
The first end of gas device 2 is provided with air inlet and jet water inlet, and the second end is provided with jet-flow aeration jet 3, jet aerator 2
Jet-flow aeration jet 3 towards regulating reservoir 1 side wall.In regulating reservoir 1, paper waste convey to sewage disposal device it
Before, the jet aerator 2 in regulating reservoir 1 carries out Air Exposure to paper waste, by jet aerator 2, paper waste is provided
