Levy and be, comprise the steps:
1) add alkali to water storage tank, PVA high concentrated organic wastewater pH regulator will be contained to 8-10；
2) waste water after pH adjusted, is delivered to iron-carbon micro-electrolysis reaction tank through dosing pump, utilizes aerating machine that it is carried out aeration
In the case of, start agitating device simultaneously, carry out iron-carbon micro-electrolysis process；
3) after iron-carbon micro-electrolysis processes, enter sedimentation tank, in sedimentation tank, add CPAM carry out flocculation sediment；
4) after flocculating sedimentation, the water outlet of sedimentation tank enters Fenton reactor, adds acid for adjusting pH to 3-5, add ferrous sulfate and
Hydrogen peroxide, is sufficiently stirred for, and carries out Fenton's reaction；
5) precipitation filters, and regulation pH water outlet enters clear water reserviors.
Technique the most according to claim 4, it is characterised in that described in step 1) containing PVA high concentrated organic wastewater
