The concentration of body and flow, and gas liquid reaction will not produce the waste materials such as chemical sludge, be easy to use and manage.
Hydroxyl radical free radical has very high oxidisability, is widely used in depth-averaged model technique, is common in the difficult fall of process
Solution organic pollution.Ozone _ hydrogen peroxide combined treatment process is the method that ozone and hydrogen peroxide are applied to water process simultaneously, its
Reaction mechanism is as follows：
H2O2→HO2 -+H+；
O3+HO2 -→·OH+O2 -+O2；
O3+O2 -→O3 -+O2；
O3 -+H2O→·OH+HO-+O2.
During the course of the reaction, ozone and hydrogen peroxide can produce hydroxyl radical free radical, and the pollutant such as parachlorophenol play senior oxygen
Change acts on, and removes the COD in waste water.
When processing industrial wastewater using ozone process, need to consider the production cost of ozone gas, ozone in water
The key problem in technology such as the haptoreaction of mixing uniformity, ozone and pollutant, the whole utilization efficiency of ozone gas.Existing ozone
Reactor（As Chinese patent CN103936195A）Refer to and be filled with quartz sand layer, active carbon layer and scum layer in inside reactor
As filler, this device does not arrange aerator before waste water enters filler, ozone gas is spread in waste water, reacts bottom
Thing can be sufficiently mixed have been affected, and needs in the filler certain time in reactor to change, and does not refer to ozone reactor
Disassemble design, have influence on the further maintenance of inside reactor and change.
