Description
Technical field
The utility model relates to water treatment field, is specifically related to a kind of earth's surface and sinks to submerged filter tank diafiltration water intake system.
Background technology
The method for fetching water of current domestic Drinking Water for Residents mainly divides three major types:
One, earth's surface method for fetching water
Adopt floor treatment method, by extracting the earth surface water source of rivers and lakes, being transported to the PROCESS FOR TREATMENT such as ground water factory carries out precipitating, flocculates, clarifies, filters, drug-treated, sterilizing, after reaching drinking water national standard, being transported to water supply network again.
There is following shortcoming in the mode that this ground water factory carries out fetching water:
(1) floor space is large, and scale is taken up an area all at several thousand to several ten thousand square metres in general water factory, is restricted for mountain area and the application of shortage of land resource area;
(2) construction cost is high;
(3) in complicated treatment process and processing procedure, repeatedly energy consumption causes running cost high.
Two, natural filtering layer diafiltration method for fetching water
Natural sand boulder bed (the natural filtering layer that river basin is formed through alluviation in 1 years, also referred to as aquifer) in containing clean clear water, by with water intake facilities such as influent well, radial, large open wells, take the phreatic water of certain depth in natural filtering layer, after the filtration of the river of riverbed surface under gravity constantly by natural filtering layer simultaneously, supplement phreatic water, the techniques such as the precipitation that ground factory applies, flocculation, clarification, filtration treatment once complete in natural filtering layer infitration process at surface water.
The method is the both economical method for fetching water that recent two decades starts comparatively to popularize, and be mainly used in the small and medium-sized cities and counties and townships town etc. of each large watershed middle and upper reaches bank, its advantage is:
(1) floor space is little, under water intake facilities is mainly built in riverbed, only need arrange a water intake pumping station near riverbed, general occupation of land less than 1000 square metres;
(2) construction cost is low, because water treatment procedure make use of natural filtering layer, without the need to the complex facilities of ground water factory;
(3) running cost is low, and infiltration process is by natural gravity, without the need to consuming the energy in addition.
But there is following shortcoming in natural filtering layer diafiltration water intaking:
(1) relatively high to the water quality requirement at water source, because water treatment procedure is the natural filtering layer that places one's entire reliance upon, and natural filtering layer formed after its character cannot change, it is restricted to water treatment capacity, is only suitable for being applied to each basin middle and upper reaches water quality better regional;
(2) limit by geological conditions, natural filtering layer diafiltration water intaking requires comparatively large to thickness of filter bed, be generally 8 ~ 10 meters, but also require whether filtering layer composition character meets water treatment, application restriction is larger;
(3) natural filtering layer area requirements is larger, the infiltration rate of natural filtering layer can not manual control, and the infiltration rate v value of the natural filtering layer being applicable to water intaking is general all very little, if ensure certain aquifer yield, need larger water intaking area, more dry point, the length of underground water intake pipe and the corresponding increase of difficulty of construction;
(4) natural filtering layer diafiltration water intaking, silt phenomenon ubiquity up, run about 5 years aquifer yields and generally reduce 30%, decay after 5 years faster, aquifer yield is unstable, water factory is restricted application life, because natural filtering layer is the open filtering layer of non-boundary, and area is large, thickness is high, and the maintenance maintenance silted up for technological means process filtering layers such as application backwashes is very difficult, maintenance cost is very high, is the disadvantage of natural filtering layer diafiltration water intaking.
Three, deep phreatic water taked by deep-well
By boring deep-well, take the method for deep phreatic water, because the current groundwater resources of China are seriously deficient, the country's strictly exploitation of restriction to underground water.
