。
The purification method of a kind of activated carbon and milipore filter integrated system, comprises the following steps：
A, raw water primary purification
Raw water is sequentially sent to self-cleaning filter 3 by raw water pump 2 and ultrafiltration apparatus 4 carries out primary purification, and raw water is first passed through from clear
The filtering suspended impurity of filter 3 is washed, then by ultrafiltration apparatus 4 to the impurity such as suspension, colloid, protein and microorganism in water
Progress is filtrated to get primary purification water；
B, primary purification water circulation
Primary purification water carries out purification by activated carbon filter tank 5 and imported in circulating water line 8；
C, mixing circulation purification

D, purified water water outlet
Circularly purifying water is exported by outlet pipe 7.
E, ultrafiltration backwash
The valve 10 of circulating water line 8 is closed, by backwashing water pipe 11, reversely importing ultrafiltration apparatus 4 is carried out circularly purifying water
Cleaning, flushing waste water is flowed out by wastewater effluent mouthful B.
In use, raw water by water inlet pipe be promoted to through raw water pump self-cleaning filter remove water body in most suspended substances,
Enter ultrafiltration apparatus after particulate matter, reduction turbidity, the water outlet after processing has removed 90% organic matter and microorganism, then entered again
Enter activated carbon filter tank, the pollutant such as ammonia nitrogen in water removal is removed by charcoal absorption function.The water outlet of activated carbon filter tank again with original
Water is mixed, and thus reduces the pollution level of raw water, to protect milipore filter to reduce its pollution, so that ultrafiltration membrane flux is effectively ensured,
Prolonging service lifetime of film.Activated carbon has the big characteristic of specific surface area, can lead to very strong mistake adsorption capacity remove colourity in raw water,
The pollutants such as odor, ammonia nitrogen, dissolved organic matter and synthesis of organic substance improve effluent quality.In addition, activated carbon chemical stability
It is good, can strong alkali-acid resistance, be amenable to water logging, high temperature etc..But in traditional water treatment technology, activated carbon is generally to be intended for single use, and it is inhaled
Attached capacity utilization is very low, and the cost of use thus brought is very high.Hyperfiltration technique can effectively remove almost all pathogenic microorganisms,
Including Cryptosporidium, giardia lamblia, bacterium and virus etc., effluent quality typically can reach water standard and microbiological indicator wanted
Ask.In addition ultrafiltration can retention phase to molecular weight range be 500~106Material, and the molecular weight of natural Organic substance in water is big
Part is also in this scope, therefore ultrafiltration can relatively efficiently remove the organic matter in raw water.Simultaneously because using hyperfiltration technique
Coagulant can be not added with, the consumption of disinfectant is reduced, therefore the growing amount of DBPs in water can be substantially reduced, so as to improve water
Chemical safety.But, the raw water characteristic such as suspended material, organic matter, high-valence cationic is equal in water in the application for hyperfiltration technique
The performance of milipore filter can be constituted influences, so as to reduce the flux and service life of film.It is typically in existing processing procedure
After raw water is gone into the pollutants such as oil removal, partial organic substances through activated carbon, then by subsequent ultrafiltration workshop section remove other organic matters,
Colloid and microorganism etc..But in this technological process, due to charcoal absorption, substantial amounts of suspension and partial solubility have
Machine thing, so that the removal effect to ammonia nitrogen is reduced, and also activated carbon granule can be polluted to milipore filter, reduce milipore filter
Flux, having on ultrafiltration effect significantly influences.In order to overcome the deficiencies in the prior art, by activated carbon and ultrafiltration to big point
The retention sieving actoion of the pathogenic microorganism such as sub- organic matter and bacterium is integrated well.Raw water is gone through ultrafiltration workshop section first
After most of colloid, solid particle, germ, bacterium, activated carbon filter tank is entered back into.Due to hyperfiltration technique by suspension, have
Machine thing has been removed, therefore activated carbon can preferably play the treatment effect to ammonia nitrogen.Water outlet after charcoal treated again with
Raw water is mixed, and ultrafiltration workshop section is returned by self-cleaning filter, so that effectively protect milipore filter not polluted by activated carbon, and then
Ultrafiltration membrane flux is also improved, extends milipore filter service life.
