Description
Technical field
The utility model relates to a kind of drinking water deep treatment facility, the piped direct-drinking water pretreatment system of say so more specifically a kind of tap water materialization and biochemical treatment.
Background technology
Water pollutes serious day by day today, poisonous in the source water, harmful organic chemical pollutant content rises just year by year, particularly dissolved organic matter (DOC) generates disinfection byproduct (DBP) (DBP) with liquid chloro reaction, and long-term drinking contains the water of these mutagenic organic active substances, is easy to generate pathology.Traditional waterworks water purification and sterilization process, can not remove effectively that difficulty in the water decomposes with compounds such as solvability organic pollutant, mutagen and ammonia nitrogen, can not reach the user to drinking water safety, healthy requirement.
In order to reach requirement healthy, safe drinking water, it is the drinking water deep treatment system of core that more domestic and international water factories and community have occurred with nanofiltration and reverse osmosis membrane processing, set up a new independently closed circulation waterworks, capable of direct drinking for the user, be called piped direct-drinking water, also be supplying water in different qualities.Requirement healthy, safe drinking water matter that nanofiltration and reverse osmosis membrane filtration can satisfy, but influent quality is had relatively high expectations, need former water is carried out pre-treatment, and be prone to organic contamination, biological pollution and the obstruction of film.Pretreatment system at present commonly used is mainly combined by devices such as sand filtration, ozone, biological activated carbon and secondary filters, not only complex process, and filtrate is heavier, floor space greatly, weak effect, back flushing be frequent, improved the pre-treatment expense.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, a kind of improved piped direct-drinking water pretreatment system is provided, this system has not only significantly prolonged the cycle of operation, has reduced the back flushing number of times, has cut down the consumption of energy, stable operation, and the water outlet effect stability, satisfy the requirement of subsequent film processing to water inlet; For water quality tap water preferably, water outlet can directly be drunk.
For achieving the above object, design of the present utility model is:
The utility model piped direct-drinking water pretreatment system adopts a kind of novel porous elastic filter material.This poroelasticity filtrate material is a urethane, has following feature and advantage:
1) it is characterized in that this novel filtering material space is big, density is little, flexible and the space is many.
2), can reduce the back flushing number of times and save the back flushing water yield because the big advantage in its space has the water environment capacity than the high several times of sand filtration.
3) since density little, from heavy and light, can save the executive cost of strainer.
4) owing to have elasticity, can make it be applicable to the multiple water treatment purposes by adjusting to its pore size.
As being used for the processing of drinking water source, also can be used for sanitary sewage or Industrial Wastewater Treatment and reuse.
5) because it has more than the quantity and the hole of suitable size, suit between the filtering material inner skeleton, to form ultrafine microbial film, not only suspended substance there is good cutoff performance, and organism is had good removal performance.
The poroelasticity filtrate is cut into the cubes that profile is 7mm * 7mm * 7mm, the column shape filter of packing into, being provided with above filter can be to the device of filtrate compression, the i.e. porous plate that can move up and down; Utilize porous plate to the exert pressure pore size of needs of poroelasticity filtrate, rate of compression is 70%.After tap water in the water tank is squeezed into poroelasticity filtrate post by water pump, water is by behind the filter material layer, grow microbial film on the filler gradually, organism in the water, ammonia nitrogen and nitrite are degraded by microorganisms, bigger particulate matter and suspended substance and other metal ions are held back by filtrate and microbial film, reduce turbidity; After water outlet flows into activated carbon column, poisonous and hazardous material and dechlorination in the charcoal absorption water, and grow microbial film, organism is further degraded, transfer remaining ammonia nitrogen and nitrite to nitrate simultaneously, and hold back a part of particulate matter and suspended substance, thereby further reduce turbidity and other Pollutant levels; Water after the processing enters water storage tank, carries out ultraviolet-sterilization, kills the microorganism in the water outlet of charcoal post, and pending subsequent film is handled.
According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of piped direct-drinking water pretreatment system, comprise a water tank, be connected with a water pump, an activated charcoal filter and a ultraviolet sterilizer behind the water tank in turn, it is characterized in that before activated carbon filtration, having a compressible poroelasticity media filtration vanning to put, pending former water is behind poroelasticity media filtration device, activated charcoal filter, and water purification is exported behind ultraviolet sterilizer.
The filtering material material of above-mentioned compressible poroelasticity media filtration device is a urethane, and it is cut into cubes and the filter housing inner chamber coupling that profile is 7mm * 7mm * 7mm.
The structure that above-mentioned compressible poroelasticity media filtration device can change rate of compression according to the water quality situation of pending former water is: on poroelasticity media filtration device top the porous plate that can move up and down is set and is pressed on the poroelasticity filtrate; Selecting rate of compression during filtration is 50%～70%.
On the connecting tube valve and under meter are housed between above-mentioned water pump and the poroelasticity media filtration device, valve and under meter also are housed on connecting tube between poroelasticity media filtration device and the activated charcoal filter; The water-in of described poroelasticity media filtration device and activated charcoal filter is all on top, and water outlet is all in the bottom, and spillway is all arranged at top.
The utility model advantage compared with prior art is as follows:
1) adopts above-mentioned technology, former water is through the absorption of dual microbiological deterioration purification and gac, removed hazardous and noxious substances a large amount of in the water, suspended substance and metal ion in the water also is purified simultaneously, and through germicidal treatment, water conditioning after the processing reduces the film contamination of heavy to greatest extent.
2) owing to adopt the poroelasticity filtering material of compression before gac, the pollutant holding capability of system increases, and the cycle of operation was brought up to 60 days from original about 5 days, had increased more than 10 times; Reduce the back flushing number of times and the recoil water yield of system, reduced the pre-treatment cost.
3) owing to adopted compressible poroelasticity filtering material, can change rate of compression flexibly according to the water quality situation of former water, reach the stable treated effect, thereby improve the anti-pollution load of system, suitability strengthens.
4) during the back flushing of poroelasticity filtrate, move on the porous plate, recover the original-pack of poroelasticity filtrate, made things convenient for back flushing, saved the water yield of back flushing.
5) simple, the handled easily of this system design, strong from heavy and light, suitability; For water quality tap water preferably, the water quality after the processing can reach country's " direct drinking water water quality standard ".
