the hydraulic telescopic rod 41 is started again to drive the central rod 43 to ascend until the mounting plate 44 is separated from the liquid guide port 13 and stops, at the moment, the first limiting rib 431 on the surface of the central rod 43 enters the first limiting groove on the inner wall of the second rotating pipe 32, and at the moment, the saline waste liquid containing organic pollutants flows to the filter plate 31 from the liquid guide port 13, it is noted that in the process of adjusting the position of the central rod 43 through the hydraulic telescopic rod 41, the driving piece 51 does not need to be closed, therefore, when the saline waste liquid containing organic pollutants flows to the filter plate 31 from the liquid guide port 13, the rotating central rod 43 can drive the second rotating pipe 32, the first cleaning brush 33 and the second cleaning brush 34 to rotate through the first limiting rib 431 and the first limiting groove, the rotating first cleaning brush 33 and the second cleaning brush 34 can simultaneously play a role in preventing the organic pollutants from blocking the filter plate 31, besides, when organic matters on the surface of the filter plate 31 need to be discharged, the rotating first cleaning brush 33 can also clean the organic pollutants to a position close to the sewage discharge pipe 14, so as to facilitate pollution discharge;
after the waste liquid after biological treatment is filtered and discharged into the waste water scale inhibition bin 15, the liquid pump 65 is started, the liquid pump 65 can discharge the scale inhibitor in the scale inhibitor storage box 64 into the central pipe 61 through the main liquid discharge pipe 66 and the branch liquid discharge pipe 67, and finally the scale inhibitor is discharged into the waste liquid in the waste water scale inhibition bin 15 through the mesh pipe 62, the mesh pipe 62 rotating around the central pipe 61 and the stirring rod 46 rotating around the central rod 43 can also play a role in stirring the waste liquid, so that the scale inhibitor and the waste liquid are fully mixed, the scale inhibition is quickly slowed down, when the pH value monitoring sensor 17 and the computer control device 21 monitor that the pH value of the concentrated brine is regulated to acidity (5-7), the computer control device 21 can automatically close the driving part 51 and the liquid pump 65, the purpose of quickly regulating the pH value of the waste liquid is achieved, and finally the waste liquid after scale inhibition pretreatment can continuously enter the membrane distillation treatment device through the connecting pipe 16 to carry out membrane distillation treatment.
