Technical field
The utility model relates to a kind of waste disposal plant, relates in particular to a kind of little electrolytic iron carbon equipment that utilizes electrochemical principle to handle industrial sewage.
Background technology
The most frequently used and effective treatment process was the iron-carbon micro-electrolysis treatment process during the high-concentration hardly-degradable organic industrial sewage was handled, utilize electrochemical principle to handle little electrolytic iron carbon equipment of industrial sewage, its principle is, owing to contain carbon in the iron powder, when sewage contacts with iron powder, iron is anode, and carbon is negative electrode, and following electrochemical reaction takes place:
Anode: Fe-2e → Fe
2+E
0(Fe
2+/ Fe)=-0.44V
Negative electrode: 2H
++ 2e → 2H → H2E

By iron carbon principle as can be known, there is atomic hydrogen to produce newborn atom state hydrogen and Fe during iron carbon generation electrochemical reaction
2+Chemical property is active, can under electrical effect oxidation-reduction reaction take place with the many components in the waste water solution, and the organism fracture that can make part have ring texture generates the easily open loop organic constitution of degraded;
In addition, under acid aerobic condition, iron itself also is a kind of stronger reductive agent; Simultaneously, the electrochemical energy of iron carbon electrochemical reaction is higher, can make the colloid electrophoresis deposition in the solution, removes the part colloidalmaterial; The electronics that anodic reaction is emitted can make some unsaturated link(age) scission of link or long-chain compound fracture; Negative electrode produces a series of intermediate reaction products, as O
