Used as the further improvement of above-mentioned sand filtering device, the sand filtration medium is quartz sand.Quartz sand as sand filtration medium, Little with filtration resistance, specific surface area is big, and resistance to acids and bases is strong, the advantages of resistance tocrocking is good.
As the further improvement of above-mentioned sand filtering device, the sandfiltration pot include tank body, be arranged at it is removable at the top of tank body Unload formula top cover and water inlet pipe, be arranged at sand filtration medium with the blow-off pipe of upper tank body, be arranged at the outlet pipe of tank base, it is described Water inlet pipe is provided with water intaking valve, and blow-off pipe is provided with blowoff valve, outlet pipe and is provided with outlet valve.Top cover is detachable, convenience The installation of ultraviolet sterilization device and the placement and replacement of sand filtration medium inside sandfiltration pot, above-mentioned overall structure realize that sewage is entered With the output of water purification after sterilizing, filtration.
Further, the tank base is provided with backwash trachea, and the backwash trachea is provided with backwash air valve, institute State the backwash gas confession that backpurge system is included the backwashing water feedway connected with outlet pipe and connected with backwash trachea To device.More thoroughly cleaning for tank interior sand filtration medium is thus achieved, improves the filter effect of sand filtration medium.
Further, the sand filtration pot bottom is provided with the Dropbox for propping sand filter medium.Dropbox is played to sand filtration medium Good supporting role, also so that sewage obtains uniform filtering.
Below by way of accompanying drawing and specific embodiment, the utility model is described in further detail.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Which is elaborated as a example by the application in sewage water filtration below by way of this utility model.
As shown in figure 1, this utility model sand filtering device, including sandfiltration pot 1, the sand filtration medium 4 that is arranged in sandfiltration pot 1 with And the backpurge system connected with sandfiltration pot 1.The sandfiltration pot 1 include tank body 110, be arranged at it is detachable at the top of tank body 110 Top cover 160 and water inlet pipe 120, it is arranged at sand filtration medium 4 with the blow-off pipe 150 of upper tank body 110, is arranged at 110 bottom of tank body Outlet pipe 130, be bolted between top cover 160 and tank body 110, the water inlet pipe 120 is provided with water intaking valve 121, row Dirty pipe 150 is provided with blowoff valve 151, outlet pipe 130 and is provided with outlet valve 131.110 bottom of the tank body is provided with backwash trachea 140, the backwash trachea 140 is provided with backwash air valve 141, and the backpurge system includes anti-with what outlet pipe 130 was connected Flush water supply device and the backwash gas feedway connected with backwash trachea 140, backwashing water feedway are tank The recoil operation of body 110 provides backwashing water, and backwash gas feedway provides backwash gas for the recoil operation of tank body 110, The sand filtration medium 4 is quartz sand, and the two groups of ultraviolet sterilization devices 2 in left and right, the ultraviolet-sterilization dress are provided with inside the sandfiltration pot 1 Putting 2 includes the ultraviolet lamp tube 210 being arranged inside sandfiltration pot 1 and the transparent lamp shade 220 shrouded outside ultraviolet lamp tube 210, The transparent lamp shade 220 is the shell that quartz material is constituted, if cost conditions can also adopt crystal material in the case of allowing The shell that material is constituted, the ultraviolet sterilization device 2 hang and are arranged above sand filtration medium 4, and the ultraviolet sterilization device 2 is solid The power supply 3 being connected with ultraviolet sterilization device 2 is additionally provided with the inwall of sandfiltration pot 1, the sandfiltration pot 1, the power supply 3 is fixed In the outer wall of sandfiltration pot 1.The sand filtration pot bottom is provided with the Dropbox for propping sand filter medium, and the sand filtration medium 4 passes through water The flat Dropbox 5 for being arranged at 1 bottom of sandfiltration pot is supported.Wherein preferably the sandfiltration pot 1 is overall and Dropbox therein 5 is not using Rust Steel material is constituted.
Hereinafter using method of the present utility model is described further:
This utility model sand filtering device is first turned on water intaking valve 121 when filter operation is carried out to sewage so that sewage from Water inlet pipe 120 is entered inside sandfiltration pot 1, is turned on the power so that ultraviolet sterilization device 2 is opened afterwards, and sewage is in ultraviolet sterilization device Sterilizing process is obtained in the presence of ultraviolet lamp tube 210 in 2, ultraviolet lamp tube 210 is avoided in the presence of transparent lamp shade 220 Affected by water, the sewage after disinfecting constantly is filtered in 4 quartz sand of sand filtration medium, opens outlet valve afterwards 131, the clear water after above-mentioned sterilizing is filtered is flowed out from outlet pipe 130 through Dropbox 5, and the final clear water for flowing out disclosure satisfy that The purity requirements after sterilizing and filtration in sewage disposal process.The ultraviolet sterilization device that this utility model is set up 2 not only cause the requirement of sewage purification effluent quality has been reached from 1 water outlet of sandfiltration pot, and cause sand filtering device carrying out sewage During filtration, periodically to device interior disinfection the bacteria breed in sand filtration medium can be reduced, beneficial to the mistake of follow-up sewage Filter, coordinates the backwash operation of backpurge system to enable to sand filtering device and keeps original filter effect.Above-mentioned sterilizing, filtration behaviour After finishing, water intaking valve 121 is closed, open backwash air valve 141, start backpurge system so that backwashing water is by outlet pipe 130 enter sandfiltration pot 1, and backwash gas enter sandfiltration pot 1 by backwash trachea 140, and thus the quartz sand in sandfiltration pot 1 is in recoil Cleaned under the double rinse of wash water and backwash gas, opened blowoff valve 151, backwashing water clean after quartz sand with Backwash gas discharge sandfiltration pot 1 via blow-off pipe 150, after system backwash terminates, close backwash air valve 141 and blowoff valve 151, Backwashing water and backwash gas stop supply, and unnecessary water is flowed out from outlet pipe 130, quartz sand natural sedimentation under gravity Compacting.What deserves to be explained is, in order to ensure ultraviolet-sterilization effect, periodically need to clear up transparent lamp shade 220, ensured with this The bactericidal effect of ultraviolet germicidal 210.
