Description
Technical field
The present invention relates to the drinking water treatment technology, relate in particular to a kind of appliance for treating drinking water based on ultra-filtration equipment.
Background technology
At present, domestic conventional water preparation process is a traditional technology, i.e. coagulation, deposition, filtration (sand filtration), sterilization.Along with the continuous deterioration of surface water quality and the raising of water quality standard for drinking water, traditional water preparation process has been difficult to satisfy fully drinking-water quality requirement up to standard gradually.
In the tradition water preparation process, sand filtration technology floor space is big, water distribution system is had relatively high expectations, and filtering accuracy is low, and delivery turbidity is about 1NTU.In the practical applications, except that need ensured strict design, mounting condition, also needs safeguarded regularly, overhaul, otherwise were difficult to guarantee the normal purifying water effect of sand filtration system.
On the other hand, along with developing rapidly of industrial and agricultural production, a large amount of pollution substances are drained into surface drainage system, have caused contaminated water source.The water treatment capacity of traditional technology is limited, can't effectively remove the pollution substance of trace in the water, and difficulty satisfies China's requirement growing to drinking-water quality.
In view of this, be reply micro polluted source and burst Pollution situation, that present domestic research is more is " ozone-biological activated carbon " (O
3-BAC) technology.This technology is to COD
MnClearance is merely 15-25%, and (AOC) almost can not remove to refractory organic; Micro activated carbon particle is inevitably carried in this technology water outlet meeting secretly, has a large amount of bacteriums in these particulates, can't thoroughly kill through sterilizing; In addition, this technology construction cost is high, and running technology is complicated, should not promote on a large scale.Therefore, be necessary to develop the novel drinking water treatment process that is applicable to existing water quality condition, ensure that resident's tap water is healthy.
Ultrafiltration (hereinafter to be referred as UF) is a kind of development water treatment new technology rapidly, obtains widespread use in a plurality of fields at present, and ultrafiltration in the main application characteristic in drinking water treatment field is:
(1) can remove most absurd creatures, delivery turbidity can remain in the 0.1NTU;
(2) can remove nearly all bacterium and most virus;
(3) low molecular melting organic matter had the part clearance;
(4) the project occupation of land area is little, and it is convenient to install, overhaul.
At present domestic existing many gacs and ultra-filtration technique are to the individual event or the combination research achievement of the advanced treatment of water; But majority is applied to after traditional drinking water treatment technology; Promote and support link as water quality, increased cost of investment on the one hand, also brought higher working cost on the other hand; This make ultrafiltration technology in the drinking water treatment field slower development, influenced the application in this field of ultrafiltration technology.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention provides a kind of appliance for treating drinking water based on ultra-filtration equipment; Substitute the sand filtration technology of traditional technology system water through ultra-filtration equipment; Reduce cost of investment, improve effluent quality, and reduce the chlorination of drinking water amount, prevent chlorinated secondary product generation, increase drinking water safety property, improve the tap water mouthfeel.
Technical scheme: for realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of appliance for treating drinking water based on ultra-filtration equipment; Comprise one-level lift pump, coagulative precipitation tank, ultra-filtration equipment and clean water basin; Filtering basin huge in traditional water preparation process have been deducted; The water outlet of said one-level lift pump connects the water-in of coagulative precipitation tank, and the water outlet of coagulative precipitation tank connects the water-in of ultra-filtration equipment through the ultrafiltration water pump, and the water outlet of ultra-filtration equipment connects clean water basin.
