What this utility model was achieved through the following technical solutions.
Coal chemical industrial waste water electrochemicial oxidation device include electrochemical reactor, bag filter, active carbon filter,
Centrifugal pump, intermediate water tank；Electrochemical reactor, bag filter, intermediate water tank, active carbon filter are sequentially connected；Electrochemistry
Electrode assemblie is set in reactor, and with boron-doped diamond electrode as anode, stainless steel electrode is negative electrode to electrode assemblie.
Electrode assemblie is by the electrode plate groups of 12 pieces of parallel distributions into electrode board size is 250mm × 500mm.
The filtering accuracy of bag filter is 0.08mm.
Filtrate adopts cocoanut active charcoal in active carbon filter, and granularity is 6-12 mesh.
Electrochemical reactor can produce great amount of hydroxy group free radical after being powered（·OH）, hydroxyl radical free radical is a kind of important work
Property oxidant, with extremely strong oxidability, can by hardly degraded organic substance, ammonium oxidation in coal chemical industrial waste water into innocuous substance,
The precipitate such as the solid particle produced in course of reaction are collected through bag filter.
The beneficial effects of the utility model：This utility model adopts boron-doped diamond electrode, compares traditional electrode, can be formed
Higher oxygen current potential so that the Organic substance that traditional high-level oxidation technology cannot degrade is degraded；The electrode has extremely low background
Current value, battery lead plate not power consumption substantially, electric energy itself is mainly used in the degradation process of Organic substance, compared with traditional electrode plate,
Reduce operating cost；The battery lead plate is less scaling, long service life；The plant automation degree is high, can be according to influent quality
The power-on voltage of difference adjustment electrochemical reactor and conduction time, reach the purpose of energy efficient.
