** The Whole transaction Procedure
(Single chemical technology, Chemistry/Biology and Chemistry
/Biology /Physical combination technology)
** Application (Apply to indoor
pretreatment of the water circulation use, or indirectly let
to publication equipment and pipe end water translation
which applied to directly let to river and bay)
** Remove Compound (Poisonous or
colored substance ‘s oxidation transformation, decrease
comprehensive parameter (DOC or COD), disinfect or remove
grain substance)
Usually can be able to decrease ozone
dosage and running fee by ozone oxidation combined with
biology divide process technology (Reference to 03-biology
transaction –03 system).
1.Disinfection
It’s necessary to disinfect wastewater to
reach certain water quality before wastewater pour to
include water. It’s important to disinfect if to directly
apply the transaction water for irrigate water or technology
water, moreover it needs much more ozone volume than
drinking water. The most popular disinfector is chlorine and
chlorine dioxide，and
chlorine can forms the disinfection outgrowth (especially
trichloromethane ,THMS) which is come to light. People is
more and more interested in the use of ozone due to
potential outgrowth.
Often use ct concept (dissociate
disinfector chroma multiplication effect touch time t) of
Chick-Watson law during the chemical disinfection design.
Lots of past and recently research show that, ozone is one
kind of effetely and potential disinfector, better than
dissociate chlorine and chlorine dioxide
2.Inorganic Compound Oxidation
In order to destroy poisonous
substance in wastewater, we need inorganic compound
oxidation. It’s limited to remove cyanide. cyanide is
frequently use for electro analysis technology in metal
process and electrical industrial. It exists in dissociate
shape CN-, and complex compound Shape which is combined with
Fe or Cu in common. Ozone and dissociate chlorine react
actively when氰離子
chroma higher than 5mg/L,it means that action can be
controlled by 傳質(zhì)
process. However絡(luò)的氰化物is
stable for ozone .Can remove NO2- and H2S/2-. Both can react
with ozone quickly.
3. Organic Compounds Oxidation
Organic Compound brings problems in
industrial wastewater. Usually ought to transact mix liquid
include different substance and chroma. The major tasks for
Ozone Oxidation wastewater transaction is as the following:
** Transform poisonous compound
** Partly oxidize component in DOC
which is difficult for biology decompounds so as to improve
function of following biology decompounds.
** Elimination chroma.
It’s difficult to mineralize
completely DOC by chemical method ,it’s the same as
drinking water transaction. Suggest that
using Ozone Oxidation combined others technology. Whether
it’s successful depends on review by total DOC??. Ozone
Oxidation system has been applies to wastewater transaction,
for example garbage filters liquid, spin, pharmacy and
chemical industrial wastewater. The major polluted substance
is Organic Compound, which is difficult to decompound. It
can classify as follows:
** Humus (brown or yellow) in garbage
filters liquid and absorbed AOX
** Colored aromatic compounds in spin
wastewater (compounded with ???)
** Poisonous or biocide substance(for
example, pesticide)produced in pharmacy and chemical
industrial
** Activating for cosmetic and other
industrial

and Fe(OH)3,they are easily reactor, conduit or valve, and
it’ll destroy pump.
4.Wastewater Oxidation water quality,
water volume analysis
According to the poured wastewater in
citizen life district, the important superscalar is COD,
BOD, SS, various colloids, and various bacteria, make
sampling analysis, and then make a report.
