The purpose of this utility model reaches by following measures, specific embodiments is: a kind of multistage purpose ceramic-film filter, comprise bearing, be fixed on the low head of bearing top, be fixed on the filter cylinder of low head top and the upper cover of filter cylinder top; Described filter cylinder is inner is provided with quartz sand filtration layer with low head link; Described filter cylinder is inner is provided with ceramic membrane filter layer with upper cover link; Described filter cylinder lower sides is provided with inlet, and upper cover upper end is provided with liquid outlet, and low head lower end is provided with sewage backwash mouth; Described inlet is connected with to establish valvularly has feed tube and back flush drain pipe, and feed tube and direction to rinse drain pipe in parallel; Described liquid outlet is connected with establishes valvular drain pipe and back flush feed tube, and drain pipe and the parallel connection of back flush feed tube.
Adopt said structure, industry water enters inlet and then arrives inner barrel by opening valve feed tube, oarse-grained suspension is under Action of Gravity Field, Direct precipitation is to low head bottom, filtering former water is first primary filter layer through quartz sand filtration layer, primary filter layer is installed quartz sand filter media, with the bulky grain suspension removing in 99% water quality, alleviate the filter pressure of ceramic membrane filter layer, ceramic membrane filter layer is played a protective role, utilize lamina flow principle, shortened particles settling distance, carried out the isolated by filtration of thick level; Afterwards, enter ceramic membrane filter layer, this filter course filter material has the advantages such as light weight, specific area are large, high adsorption capacity, not broken, porosity is high, filtering velocity is fast, decontamination ability is strong, filtrate even, long service life.Porosity is up to 50%, and delivery turbidity can be reduced to 1～2NTU, and the clear water after filtration flows out through liquid outlet; When quartz sand filtration layer and ceramic membrane filter layer need to be cleared up, from backwash pipeline water inlet (now drain pipe valve closing), first ceramic membrane filter layer is carried out to backwash, again quartz sand filtration layer is carried out to backwash, the water of last backwash is discharged (valve closing of the feed tube that inlet connects) from inlet along backwash fluid pipeline, the dirty material of solid that backwash is got off is discharged from the sewage backwash mouth of low head bottom; This backwash process can fully guarantee the flux recovery of filter course, prevents because filtering absorption saturatedly, and energy reduces and affects service life.
As preferably, described quartz sand filtration layer thickness (highly) is 500-1000mm, and the thickness of ceramic membrane filter layer is 1800-2000mm.Adopt above-mentioned thickness and in conjunction with the two-in-one high-efficiency ceramic membrane structure of quartz sand filtration+ceramic membrane filter, filtering water quality is higher, has saved the installing space of water treatment facilities, convenient installation, maintenance, simple operation, has reduced production cost and user's maintenance cost; According to the utility model, implement the high-efficiency ceramic film filter of preparation, its filtration index is as follows:
Water inlet suspension content≤50mg/L
Go out water suspension content < 1～2mg/L
Intake pressure: 0.3～0.6MPa
Washing time: 15min
Equipment resistance :≤0.06Mpa
Kickback pressure: >=0.35MPa.
The utility model is through particular study, avoided the single filtration of existing filtering technique, had the situation of various drawbacks, and internal structure is optimized to design, and the coagulation in purification of water quality, clarification and filtration three process are completed in a container.
As preferably, described upper cover upper end and cylinder lateral wall are provided with manhole, adopt this structure, can convenient for maintaining.
As preferably, in described inlet, be provided with feed liquor distributor, adopt this structure, can guarantee contacting with quartz sand filtration layer of industrial wastewater energy maximum area to be filtered, improve filter effect.
