The secondary interception device 10 comprises a second water inlet 9, a second filter screen 15 and a second water outlet 11 which are sequentially communicated.
The first filter 14 and the second filter 15 are both in a grid structure, and the grid gap of the first filter 14 is larger than the grid gap of the second filter 15.
The first-stage interception device 4 further comprises a first driving motor 8, a first back flushing pipe 16, a first spiral conveying equipment 17 and a first impurity outlet; the first driving motor 8 is fixedly connected with the first filter screen 14; the first backwashing pipe 16 is used for backwashing solid particles or impurities on the first filter screen 14 into the first spiral conveying equipment 17; the first screw conveyor 17 communicates with the outside through the first impurity outlet;
the secondary entrapment device 10 further includes a second drive motor 12, a second backwash tube 18, a second screw conveyor 19 and a second impurity outlet; the second driving motor 12 is fixedly connected with the second filter screen 15; the second backwashing pipe 18 is used for backwashing solid particles or impurities on the second filter screen 15 into the second spiral conveying equipment 19; the second screw conveyor 19 communicates with the outside through the second impurity outlet.
The operation effect of the existing cut-off equipment is analyzed, and meanwhile, the particle size composition of impurities in raw water is also analyzed, and the impurities in white spirit wastewater are found to be mainly 2-5 mm and 0.3-2 mm, and based on the on-site operation condition and sampling analysis data, in a preferred example, the grid gap of the filter screen 14 is 2mm. The grid gap of the second filter screen 15 is 0.3mm.
In a preferred embodiment, the structure for removing impurities in the white spirit wastewater further comprises a controller and a flow monitor; the water inlet pipe valve 2 and the overrunning pipe valve 6 are remote control valves; the flow monitor, the water inlet pipe valve 2 and the overrun pipe valve 6 are all connected with the controller through signals, and the flow monitor is installed at the front end of the water inlet pipe 1.
The working principle and working process of the utility model are as follows:
under normal operation conditions, the amount of wastewater is small or the amount of impurities in the wastewater is large, and at the moment, the water inlet pipe valve 2 is opened and the overrunning pipe valve 6 is closed. The white spirit wastewater enters an impurity removal link from a water inlet pipe 1, and the wastewater enters a first-stage interception device 4 through a water inlet pipe valve 2 and a first water inlet 3 and then reaches a first filter screen 14 of an interception core part;
the first filter screen 14 intercepts impurities on the surface of the wastewater, the wastewater passes through the first filter screen 14, and the wastewater is discharged into the secondary interception device 10 through the first water outlet 7 after passing through the first filter screen 14.
Then, the first filter screen 14 moves to the outlet of the first back flushing pipe 16 under the drive of the driving motor 8, impurities on the surface of the first filter screen 14 are flushed to the first spiral conveying equipment 17 under the action of the back flushing pipe 16, and then the impurities are discharged through the first impurity outlet.
The wastewater flowing into the secondary entrapment device 10 is further subjected to impurity removal by the secondary entrapment device 10. The working principle of the second-stage interception device 10 is consistent with that of the first-stage interception device, and the wastewater passes through a second filter screen 15 to realize impurity removal and then flows out from a second water outlet 11; then, the impurities trapped in the second filter screen 15 pass through the rotation of the second filter screen 15 and the flushing of the second back flushing pipe 18, and then are discharged out of the second-stage trapping device by the second spiral conveying equipment 19.
The primary retention device 4 and the secondary retention device 10 do not need to work simultaneously when the water amount of the wastewater is small or the impurity amount in the wastewater is small. An operator or the controller can open the overrunning pipe valve 6 by closing the water inlet pipe valve 2, so that the wastewater directly enters the secondary interception device 10 through the water inlet pipe 1, the overrunning pipe 5 and the water inlet 9, and impurities in the wastewater are removed. At this time, no wastewater flows into the first-stage interception device 4, the first-stage interception device 4 also stops working, and only the second-stage interception device 10 works, so that the wastewater treatment capacity is more matched with the design load.
The utility model aims at effectively removing impurities in white spirit wastewater and stably operating equipment. The original first-stage interception mode is changed into a second-stage interception mode, and according to the particle size distribution condition of impurities in white spirit wastewater, the first-stage interception is carried out by adopting grid bars with gaps of 2mm, the second-stage interception is carried out by adopting gaps of 0.3mm, and impurities with the particle size smaller than 0.3mm are removed by means of a subsequent process section as in the prior art. After the secondary interception strategy is adopted, the impurity interception device can equally divide the treatment load, so that the stable removal of impurities in the wastewater is realized, meanwhile, compared with the primary interception, the equipment model selection can be reduced, and the improvement under the condition of narrow land of a sewage plant is facilitated.
As shown in fig. 5, through analysis of the drainage condition in the white spirit production period and the impurity content in the waste water, the utility model can be used for making running schemes under different conditions and practicing in the running of a waste water plant, and the scheme is adjusted through the running effect, so that the annual running strategy for removing the impurities in the white spirit waste water is determined.
According to the method, impurities such as chaff and sorghum husk in the white spirit wastewater are removed in two stages, so that the operation load of single interception equipment is reduced, and the stable and efficient operation of the equipment is ensured. Meanwhile, the occupied area of a single device can be reduced by removing the device in stages, and flexible arrangement of the devices is realized in a limited space. Besides, the method is divided into two stages to remove, and can ensure stable and efficient operation of equipment by matching with the design of the overrunning pipe, thereby realizing energy conservation and consumption reduction of the process section.
The utility model is beneficial to adjusting the strategies of removing impurities such as chaff, sorghum husk and the like under the condition of different water qualities and water amounts of the white wine wastewater so as to ensure the effect of removing the impurities by a wastewater treatment plant, ensure the normal and stable operation of interception equipment and reduce the occupied area of a single equipment. The utility model is helpful for providing a determination method of the operation scheme of the wastewater plant in different periods, ensuring the efficient operation of impurity removal equipment and realizing the energy conservation and consumption reduction of the wastewater plant.
In conclusion, the method is wide in application and wide in application range, can effectively ensure stable operation of the interception device for a long time, ensure removal of raw water impurities by the white spirit wastewater treatment plant, and simultaneously realize energy conservation and consumption reduction in the plant area. The method can realize the stable and efficient removal of impurities such as chaff, sorghum husk and the like in the wastewater by the white spirit wastewater treatment plant, and ensure the stable operation of the subsequent process section. The efficient operation of the impurity removal process section under the conditions of different water quality and water quantity is ensured, and the energy conservation and consumption reduction of the wastewater treatment plant are realized.
