In facture, Fenton chemical oxidization method or other modified form Fenton chemical oxidization methods, have cost of investment it is low, to water quality
The degree of tolerance of variation is big, Operation and Maintenance is easy and operating cost is low, and other methods are then because being just set as or operating cost is excessively high
Or it is unable to reach requirement at all and more difficult is received by dealer.
Fenton reactor is catalyzed hydrogen peroxide and generates the superpower hydroxyl free of oxidisability using ferrous ion as catalyst
Base can be used to handle many used water difficult to degradate without most of organic matters in the oxidized waste water of selection.Fluidized bed-
Fenton system makes the most of packet in the way of crystallizing or precipitate of ferric iron produced by Fenton method in the way of fluidized bed
The carrier surface for overlaying on fluidized bed is one and combines same phase chemical oxidation (Fenton method), out-phase chemical oxidation (H2O2/
FeOOH), the new technology of the functions such as reduction of dissolved of fluidized bed crystallization and FeOOH.Due to the presence of filler, on the one hand reduce
On the other hand the iron cement yield of reaction provides heterogeneous catalytic reaction point for Fenton's reaction, improve catalyst use efficiency.
