Contaminate the handling process of source water.
Background technology
In recent years, with the increase of China's industrial expansion and agricultural chemicals, drinking water source is heavily contaminated, and is in
Development trend, the health polluted not only to the mankind of source water brings larger harm, and to traditional water-purifying process and water
Matter makes a big impact.Water pollution classification is more, and property is complicated, and the wherein relatively low polluted-water of pollution concentration is known as " micro- dirt
Dye " water.The characteristics of micropollutant water, is mainly shown as：Organic matter increases, ammonia nitrogen concentration increase, algal bloom etc..With normal
It is that, with simply coagulation, precipitation, filtering, sterilization process, can not eliminate at all " micro- that surface water, which is advised, for the running water processing in source
Harmful substance in pollution " water, it is difficult to ensure that effluent quality is up to standard.Many organic pollutions and heavy metal have poison in itself in water
Property, into human body after can gradually accumulate, it is very big to human health damage.And some organic micro-pollutantses are during chlorination
The generation of DBPs can be caused, such as the material such as dibutyl phthalate, haloform, halogen acetic acid, serious prestige
Coerce human health.
At present, according to raw water quality feature, by various preconditioning techniques, further treatment technique and existing conventional processes
Integrated combination, is the basic fundamental countermeasure of current contaminated micro polluted source Water warfare；Simultaneously with the development of water technology,
The handling process for seeking new and effective micro-polluted source water is also the focus of research and practice.
The application of hyperfiltration technique can carry out advanced water treatment, the micro polluting substance in water body can effectively be removed, to water

Son amount organic matter is removed from water, and PAC can effectively prevent fouling membrane in ultrafiltration membrane surface formation layer protective layer.But this
Technique charcoal end operating condition is harsh, is difficult to reclaim after first use, so as to increase processing cost；Filter tank biology backwashing water is taken out of
A large amount of PAC, influence the water quality of water distribution system, and the influence to sludge treatment is also very big.
Traditional GAC-UF（Granular activated carbon-ultrafiltration）Group technology advantage sets GAC filter tanks and ultrafiltration apparatus to connect respectively
Operation, has preferable suction-operated to Organic substance in water, while the absorption of Carbon-sand filter surface microorganism using granular activated carbon
Also there is good degradation to organic matter with attachment, and milipore filter can effectively ensure that to turbidity, the crown_interception of microorganism
The chemistry and biological safety of drinking water.
But the technique of existing GAC-UF group technologies processing micro-polluted water is all separate type, not only floor space compared with
Greatly, and if water factory's landform is unfavorable for gravity stream, need using pump lifting, so may result in power consumption increase.Ultrafiltration is retained
The concentrated water got off originally can as microbe survival on granular activated carbon nutriment, if this part of concentrated water of separate type will be direct
Discharge, causes the waste of water resource；If being delivered to technique front end with water pump, power consumption is caused to increase.So by seed activity
