Description
Technical field
The present invention relates to drinking water disinfection field of purification, in particular to the one of mark discharge is carried for waterworks water quality
Plant the drinking water sterilization device that ceramic membrane couples ozone catalytic.
Background technology
In recent years, China's water supply industry proposes mark discharge always among schedule.In the typical environment water of China and dirt
Antibiotic, DBPs, medicine and personal care articles (PPCPs) in water treatment plant's waste discharge, incretion interferent and
The exceeded report of the poisonous Recalcitrant chemicals of other persistence emerges in an endless stream, and greatly threatens aquatic ecological safety and human body is strong
Health.The Committee of Experts of Chinese city sewage disposal concept factory is by erythromycin, sulfamethoxazole, Diclofenac, brufen, Luo Hong
There are the new organic micro-pollutantses that latency environment endangers and is difficult to degrade to be classified as mycin, 7 kinds of estrogen (poisonous effect equivalent)
Science in Future in China water quality management and control target, among concerned countries policy is also breeding.The common technology stream of current China waterworks
Journey is flocculation, sand coarse aggregate ratio, sterilization (chlorination, UV or ozone), and conventional processes are removed to dissolved organic matter, ammonia nitrogen, two worms etc.
Effect on driving birds is not good, effluent quality cannot meet needs, and drinking water safety problem is extremely urgent, faces the need of technique upgrading
Ask.
Reduction and the maturation of membrane technology with film product price, application of the milipore filter in drinking water treatment is increasingly
Extensively, milipore filter can be effectively gone in water removal turbidity, particle and bacterium, floor space are small, high degree of automation.Conventional oxidation technology
Treatment micro-polluted raw, and milipore filter conventional at present is the organic polymer film for being unable to resistance to oxidation, therefore split using series connection should
For in each handling process, milipore filter to be often placed in technological process end, the barrier removed as microorganism, film skill are now only capable of
The advantage of art fails to embody.Compared with organic film, ceramic membrane energy resistance to oxidation, with high mechanical strength, membrane aperture narrow distribution range,
The advantages of long service life, can be coupled with oxidation technology and used.But membrane process applies to actual another biggest obstacle for film
Pollution, is mainly shown as filtration resistance increase and permeation flux reduction.
Ozonation technology is an environmentally friendly technology, can be H by the permineralization of partial contamination thing2O and CO2, so
And its oxidisability has high selectivity.Catalytic ozonation belongs to high-level oxidation technology, is produced using catalyst
Raw free hydroxyl, hardly degraded organic substance in enhancing degradation water, its carbon drop decoloring ability is significantly higher than simple ozone oxidation, with drop
Solution efficiency high, it is environment-friendly the features such as, its cost is also below simple ozone oxidation.
Therefore, will maximized utilization ceramic membrane and catalysis by catalytic ozonation technology and Ceramic Membranes Separating Technique coupling
The effect of ozonisation, catalytic ozonation can react with former Organic substance in water, change organic constitution, can solve ceramic membrane film
Easily by the problem that dirty, service life is short, while also can solve the problem that catalyst is difficult to the problem for reclaiming in catalytic ozonation technology.
Disclosed in CN2586692《Multiple sterilizing filtration water purifier》, using the strong oxidation of ozone, oxidation is killed in water
Various bacteria microorganism, organics removal, but its ozone utilization ratio is low, and drinking mainly for the production of drinking water machine
Water.Disclosed in CN103274547A《The deep-purifying method of soluble pollutants in a kind of removal drinking water》Using ceramic membrane mistake
Filter, ozone oxidation organic matter macromolecular are but its ceramic membrane and ozone by molecular screen membrane advanced treating drinking water after small molecule
Reaction unit floor space is big, and ozone utilization ratio is low.
The content of the invention
Present invention solves the technical problem that there is provided the drinking water sterilization device that a kind of ceramic membrane couples ozone catalytic, go out
Various bacteria microorganism in water, organics removal, and ozone utilization rate can be improved.
Technical scheme is as follows：
A kind of ceramic membrane couples the drinking water sterilization device of ozone catalytic, including ozone generating-device, gas flowmeter, original
