In the backwashing process, the rotation stirring of the stirring paddles can drive the filter materials to rotate along with the filter materials under the action of water power and collide with the filter materials due to the light weight of the filter materials, so that the trapped suspended matters fall off rapidly, and the purpose of efficiently removing pollutants is achieved.
In some embodiments, referring to fig. 1 and 2, the sidewall of the cartridge 1 is provided with a purge port 18 in communication with the reaction zone 14. More preferably, the cylinder 1 is formed by splicing an upper cylinder 11 and a lower cylinder 12, and the lower part of the upper cylinder 11 is connected with the upper part of the lower cylinder 12 by adopting a flange 13. Therefore, the device can realize quick inspection and maintenance and has the advantage of convenient maintenance and replacement. Specifically, when the conditions of reduced removal rate, low backwashing efficiency of filter materials and the like occur in a period of operation, the inside of the cylinder can be checked by opening the cleaning opening, and the filter materials in the cylinder can be cleaned or replaced. When the stirring device fails, the feeding rod is blocked or the filter material needs to be replaced integrally, the upper cylinder body and the lower cylinder body can be separated through the disassembling flange, so that the stirring device, the feeding rod and the filter material can be conveniently checked and replaced.
The specific operation process is described in detail below:
① And (3) a filtering stage: referring to fig. 1, residual water after sludge dewatering enters a reaction zone 14 from a water inlet 16 at the lower part of a cylinder 1, and under the action of buoyancy, a light filter material 7 is driven to float upwards and form a stable filter layer under the action of water inlet pressure, and after water is filled and the filter layer is formed, the suspended matter removing effect is realized; meanwhile, after the liquid level reaches the position of the filter plate 2, the disinfection liquid supply device 84 is started, and the chlorine dioxide disinfection liquid is released and injected into the filter layer by the adding rod 81, so that the chlorine dioxide disinfection liquid is fully mixed with the inlet water, the purposes of ammonia nitrogen removal and COD reduction are achieved, and meanwhile, the disinfection effect is realized. The treated water flows out through the water outlet 17 to complete the integrated treatment process. During this time, the vent valve 9 at the top of the cartridge 1 acts as a vent for the filtration process device, ensuring that the device can be operated under pressure.
② Backwashing: referring to fig. 2, when the operation is performed for a certain time, the backwash operation needs to be completed to maintain the effect of efficiently treating the surplus water. In the back flushing stage, clear water is connected to the water outlet 17, back flushing is carried out from top to bottom, under the mechanical stirring action of the stirring device 3, the filter material 7 is driven by the hydraulic action to start rotating and colliding due to the light weight, so that the trapped suspended matters fall off, and back flushing concentrated liquid can be discharged from the water discharge pipe 6 by opening the back flushing valve 61, so that the cleaning of the filter material 7 is completed.
③ And (3) overhauling: when the operation is performed for a period of time, the removal rate is reduced or the backwashing efficiency of the filter material is low, the cleaning opening 18 can be opened to inspect the inside of the cylinder body 1 and clean or replace the filter material in the cylinder body. When the stirring device 3 fails, the feeding rod 81 is blocked or the filter material needs to be replaced integrally, the upper cylinder 11 and the lower cylinder 12 can be separated through the dismounting flange 13, so that the stirring device 3 and the feeding rod 81 can be conveniently inspected and the filter material 7 can be conveniently replaced.
