Abstract
The invention relates to a water treatment method for an O3/H2O2/multiphase-Fenton combination, in particular to the water treatment method which can generate OH by a plurality of channels, which includes the following contents: the filtered water treated with the traditional water treatment technique is input into an ozone contact tower for ozone oxidation reaction; the water after ozone oxidation is added with hydrogen peroxide to react for a period of time; the yeilding water oxidized by O3/H2O2 is input in a catalyst bed for staying for a period of time, the interior of the catalyst bed is stuffed with hydroxyl oxidize iron or carrier type hydroxyl oxidize iron; the water oxidized by O3/H2O2/multiphase-Fenton is sent into a biological activated carbon filtering bed for biological treatment; after the biological treatment, the water carries out chlorination disinfection and then enters a municipal network pipeline. The principle of the water treatment method of the O3/H2O2/multiphase-Fenton combination is as follows: after the O3/H2O2 oxidation process, the residual H2O2 is taken as the H2O2 source for the following treatment technique, and the hydroxyl oxidize iron or the carrier type hydroxyl oxidize iron is introduced into the system to form an O3/H2O2/multiphase-Fenton system, thus generating the OH with strong oxidizability again.
Description
Technical field
The present invention relates to a kind of O
