Source recycles, and reduces industrial water cost, pressure of supply water, realizes and produces economic, society, the many-sided common benefit of environmental protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of two sections of embrane method recycling systems of city domestic sewage, including stabilization pond, in stabilization pond 1 one
Side be provided with connect with stabilization pond 1 water diversion tank 2, the side of water diversion tank 2 provided with connected with water diversion tank 2 raw water pump 3, in raw water pump
3 sides are provided with what is connected with disc filter 4 provided with the disc filter 4 connected with raw water pump 3, in the side of disc filter 4
First bag filter 5, the side of the first bag filter 5 be provided with connected with disc filter 4 UF film process device 6, in UF
The side of film process device 6 is provided with what is connected with backwashing pump 7 provided with the backwashing pump 7 connected with UF film process device 6, in the side of backwashing pump 7
Intermediate pool 8, the side of intermediate pool 8 be provided with connect with intermediate pool 8 booster pump 9, the side of booster pump 9 provided with and supercharging
The second bag filter 10 that pump 9 connects, it is provided with the side of the second bag filter 10 and connects with the second bag filter 10
High-pressure pump 11, the RO film process device 12 connected with high-pressure pump 11 being provided with the side of high-pressure pump 11, and in RO film process device 12 1
Side is provided with the Membrane cleaning device 13 and reuse pool 14 connected with RO film process device 12.Membrane cleaning device 13 connects with UF film process device 6.
Disc filter 4 includes the container body connected respectively with raw water pump 3 and UF film process device 6, and the filtering being provided with container body
Lamination and the spring being provided with filtering lamination.Mechanical filter uses disc filter 4, the plastic laminate of very thin particular color
It is carved with the groove of a large amount of certain micron-scales in both sides.One lamination for changing pattern of the same race is pressed in specially designed inner support.Pass through bullet
When spring and fluid pressure compress, the groove between lamination intersects, so as to produce the deep layer mistake for possessing system's uniqueness filtration channel
Unit is filtered, this filter element is mounted in a superpower performance engineering plastics filter cylinder and forms filter.In filtering, lamination is filtered
Compressed by spring and Fluid pressure, pressure difference is bigger, and thrust is stronger.It ensure that self-locking performance high efficiency filter.Liquid by lamination outside
Edge flows to lamination inner edge by groove, so as to form the in-depth filtration of uniqueness.Filtering by hydraulic pressure makes pine between lamination after terminating
Drive row automatic backwash into.UF film process device 6 is that the small granular suspended matters in raw water, colloid, bacterium are separated, and is prevented anti-
Permeate contaminated；This project uses external-compression type reinforcement PVDF ultrafiltration membrane, prevents film wire fracture completely.Contamination resistance is strong, significantly
Alleviate fouling membrane, reduce using and extending run time for chemical agent；Filtering accuracy is up to 0.02um, it is ensured that water outlet
SDI15<2.0.RO film process device 12 is main demineralizer, removes most dissolved solid, salt, a huge sum of money in raw water
Belong to ion.RO film process belongs to physical separation, screening process, does not chemically react and does not produce novel substance or the new pollutant of synthesis.
Every pollutant index clearance is up to 90% in draining after RO film process, and caused recycle-water quality is high.Washer timing
UF films and RO films are cleaned, to improve water efficiency and water quality processed, can more extend membrane lifetime.Mechanical filter sets dosing antibacterial
Device, periodically sterilized, prevent bacteria breed from influenceing treatment effect.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
