The working principle is as follows:
when the integrated device for sludge cell disruption is used, firstly, sludge to be treated is injected into the rotary disc cavity 13 through the sludge inlet pipe 16, the injection amount is 80-90% of the internal volume of the rotary disc cavity 13, then the first valve 34 is closed, the main motor 11 is started to drive the output shaft 111 to rotate at a high rotation speed of 4000rpm/min, when the rotary disc rotates, boundary layers are respectively formed on the wall surfaces of the rotary disc 133 and the first and second fixed discs 131 and 132, when the distance between the rotary disc 133 and the first and second fixed discs 131 and 132 is larger, a core area is formed between the boundary layers, in the boundary layer of the rotary disc 133, liquid flows outwards along the disc surface due to the centrifugal force, and due to the negative pressure effect, the liquid enters the mesoporous boundary layer through the second fixed disc 132 and flows outwards along the disc surface, the fluid in the core area rotates at a speed which is less than the rotation angular speed omega of the rotating disc 133 like a rigid body, fluid shear force is generated by a fluid speed gradient formed by high rotation speed, the fluid shear force acts on an activated sludge EPS structure, and the intracellular substances are dissolved out by destroying a Soluble Extracellular Polymer (SEPS), a loose extracellular polymer (LB-EPS) and a tightly adhered extracellular polymer (TB-EPS) and finally destroying the cell structure;
fluid mechanics model construction under laminar flow condition, under the cylindrical coordinate system, the writing component form is:
the fluid mechanics model is constructed under the condition of turbulent flow, and the writing component form is as follows under a cylindrical coordinate system:
constructing a fluid mechanics model under the condition of turbulent flow, wherein the fluid shear stress of a static disc boundary layer is as follows:
the model shows that the fluid shear force of the static disc boundary layer is mainly related to the thickness, the radial velocity and the angular velocity of the boundary layer, and the thinner the boundary layer, the larger the radial velocity and the angular velocity are, the larger the fluid shear force in the static disc boundary layer is;
according to the conservation of mass of boundary layer fluid of the rotating disc and the static disc, the velocity distribution of the boundary layer fluid of the moving disc can be calculated, and therefore the distribution of the shearing force of the fluid is calculated, and the following formula is shown:
the larger the particle diameter in the liquid, the greater the kinetic energy loss and the lower the impact velocity, the less wear on the rotating disc 133.
If a sludge sample in the treatment process needs to be taken for detection, a first valve 34 is opened to draw part of sludge into the sampling bottle 3;
opening a second valve 35, enabling the sludge treated by the mechanical turntable assembly 1 to enter the ultrasonic cracking assembly 2 through a second sludge guide pipe 32, opening a first sludge outlet 211 by opening a first electromagnetic valve 213, opening a second electromagnetic valve 235 of one group of sludge treatment bins 231 corresponding to the first sludge outlet, opening a first sludge inlet 232, enabling the sludge to enter the sludge treatment bins 231, then filling the next group of sludge treatment bins 231 with the sludge by the same method until each group of sludge treatment bins 231 are filled with the sludge, and then starting ultrasonic treatment;
during ultrasonic treatment, the mode of closing the slurry treatment bin 231 and starting the second ultrasonic generator 27 can be selected for closed ultrasonic treatment, at the moment, the ultrasonic treatment power is lower, but the rotating gear 41 of the driving motor 4 is matched to drive the slurry barrel 23 to rotate, so that the ultrasonic treatment efficiency can be improved, and a better treatment effect can be achieved with lower energy consumption;
if the heat treatment assisted ultrasonic advanced treatment is required, selecting a slurry treatment bin 231 required to be subjected to advanced treatment to rotate to the position right below an ultrasonic treatment barrel 22, starting a first electric push plate 221 and a second electric push plate 234, starting an electric telescopic rod 28 to enable a first ultrasonic generator 24 and a heater 25 to be deep to the slurry treatment bin 231, starting the first ultrasonic generator 24 and the heater 25 to carry out ultrasonic and heating assisted treatment, and enabling sludge subjected to advanced treatment to flow back to a mechanical turntable assembly 1 to serve as a carbon source for supplementing nitrogen and phosphorus removal so as to substantially reduce the yield of sludge;
when the treated sludge is discharged, the third electromagnetic valve 214 and the fourth electromagnetic valve 236 are opened, so that the second sludge outlet 212 corresponds to the second sludge inlet 233, and the sludge in the sludge treatment bin 231 is discharged into the sludge discharge pipe 26 for recycling.
Examples of the experiments
The integrated device for sludge cell disruption in examples 1 to 5 of the present invention was subjected to performance tests to detect the maximum sludge reduction and the release amount of phosphorus, and the results were compared with the results of tests performed by a conventional ultrasonic disruption device, and the results are shown in table 1.
TABLE 1 Experimental results in examples 1-5 and comparative examples
| Examples | The sludge is reduced by percentage | The release amount of phosphorus element% |
| Example 1 | 72.4 | 86.3 |
| Example 2 | 66.5 | 80.2 |
| Example 3 | 73.2 | 86.9 |
| Example 4 | 70.7 | 84.1 |
| Example 5 | 73.2 | 85.2 |
| Comparative example | 62.4 | 77.9 |
As can be seen from the data in Table 1, compared with the conventional ultrasonic cracking device on the market in the comparative example, the integrated device for sludge cell cracking in the examples 1 to 5 of the invention has the advantages that the maximum reduction of sludge and the release amount of phosphorus elements are obviously improved;
comparing with examples 1 to 4, it can be seen that, as the number of the sludge treatment bins 231 is increased, the improvement of the maximum sludge reduction and the release amount of phosphorus elements is facilitated, but the cost is inevitably increased due to the number of the set groups, and when the number of the set groups reaches 6, the sludge treatment effect is reduced, and the number of the set sludge treatment bins 231 in example 1 is selected comprehensively;
comparing examples 1 and 5, it can be seen that in example 5, the magnetic stirring device is additionally arranged, the maximum sludge reduction is improved to a certain extent after the arrangement, but the release amount of phosphorus elements is negatively affected, so that whether the arrangement is carried out or not can be selected according to the actual production condition.
