Description
Technical field
The present invention relates to drinking water disinfection field of purification, in particular to mention the one of mark discharge for waterworks water quality
The drinking water sterilization device of kind ceramic membrane coupling ozone catalytic.
Background technique
In recent years, China's water supply industry mentions mark and discharges always among schedule.Typical environment water and dirt in China
Antibiotic, disinfection by-products, drug and personal care articles (PPCPs) in water treatment plant's waste discharge, incretion interferent and
The exceeded report of the toxic Recalcitrant chemicals of other persistence emerges one after another, and greatly threatens aquatic ecological safety and human body is strong
Health.The Committee of Experts, Chinese city sewage treatment concept factory is by erythromycin, sulfamethoxazole, Diclofenac, brufen, Luo Hong
Mycin, 7 kinds of estrogen (poisonous effect equivalent) endangered with latency environment and the novel organic micro-pollutants that are difficult to degrade are classified as
Science in Future in China water quality manages target, among concerned countries policy is also being bred.The common technology stream of China waterworks at present
Journey is flocculation, sand coarse aggregate ratio, disinfection (chlorination, UV or ozone), and conventional processes remove dissolved organic matter, ammonia nitrogen, two worms etc.
Ineffective, effluent quality has been unable to satisfy needs, and drinking water safety problem is extremely urgent, faces the need of technique upgrading
It asks.
With the reduction of film product price and the maturation of membrane technology, application of the ultrafiltration membrane in drinking water treatment is increasingly
Extensively, ultrafiltration membrane can effectively remove turbidity, particle and bacterium in water, and occupied area is small, high degree of automation.Common oxidation technology
Micro-polluted raw is handled, and currently used ultrafiltration membrane is the organic polymer film for being unable to resistance to oxidation, therefore is split and answered using series connection
For in each treatment process, ultrafiltration membrane to be often placed in process flow end, it is only capable of the barrier removed as microorganism, film skill at this time
The advantage of art fails to embody.Compared with organic film, ceramic membrane energy resistance to oxidation, have high mechanical strength, membrane aperture narrow distribution range,
The advantages that long service life, can couple use with oxidation technology.But it is film that membrane process, which applies to actual another biggest obstacle,
Pollution is mainly shown as that filtration resistance increases and permeation flux reduces.
Ozonation technology is an environmentally friendly technology, can be H by some of the contaminants permineralization2O and CO2, so
And its oxidisability has high selectivity.Catalytic ozonation belongs to high-level oxidation technology, is produced using catalyst
Free hydroxyl, hardly degraded organic substance in enhancing degradation water are given birth to, carbon drop decoloring ability is significantly higher than simple ozone oxidation, has drop
The features such as high-efficient, environmental-friendly is solved, cost is also below simple ozone oxidation.
Therefore, catalytic ozonation technology and Ceramic Membranes Separating Technique coupling will maximumlly be utilized into ceramic membrane and catalysis
The effect of ozonisation, catalytic ozonation can be reacted with former Organic substance in water, changed organic constitution, be can solve ceramic membrane film
Problem easily short by dirty, service life, while being also able to solve catalyst in catalytic ozonation technology and being difficult to the problem of recycling.
" multiple sterilizing filtration water purifier " disclosed in CN2586692, using the strong oxidation of ozone, oxidation is killed in water
Various bacteria microorganism, removal organic matter, but its ozone utilization efficiency is low, and drinking mainly for the production of water dispenser
Water." a kind of deep-purifying method for removing soluble pollutants in drinking water " disclosed in CN103274547A uses ceramic membrane mistake
Filter, ozone oxidation organic matter macromolecular are after small molecule by molecular screen membrane advanced treating drinking water, but its ceramic membrane and ozone
Reaction unit takes up a large area, and ozone utilization efficiency is low.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of drinking water sterilization devices of ceramic membrane coupling ozone catalytic, go out
Various bacteria microorganism, removal organic matter in water, and can be improved ozone utilization rate.
Technical scheme is as follows:
A kind of drinking water sterilization device of ceramic membrane coupling ozone catalytic, including ozone generating-device, gas flowmeter, original
Water container, fluid flowmeter, gas-liquid mixing pump, reaction vessel, catalyst couple ceramic membrane, reflux unit, discharging device, air pressure
Regulating device, back purge system, the ozone generating-device, raw water vessel connect gas-liquid mixing pump by pipeline, described
Catalyst coupling ceramic membrane is placed in reaction vessel interior, and the reflux unit, discharging device are placed on reaction vessel side wall, institute
The air pressure regulator stated is placed in the upper cover position of reaction vessel.
Further, catalyst coupling ceramic membrane includes at least two ceramic membranes and catalyst, the ceramics
Film loads cobalt oxide by infusion process, and the method by coating prepares catalyst coat in ceramic membrane surface, and building is three-dimensional more
Grade catalytic carrier, it is more thorough to the catalysis oxidation of drinking water.
Further, the ceramic membrane is butterfly structure, with a thickness of 0.8-1.2mm, overall diameter 1.2-2cm, on film
There is fenestra, fenestra aperture is 100-500nm, improves the disinfection efficiency of drinking water.
Further, the ceramic membrane the preparation method comprises the following steps:
(1) raw material are used are as follows: partial size is the TiO of 0.1-0.3um290-95 parts of powder, NH4HCO31-5 parts, asphalt mixtures modified by epoxy resin
