Above-mentioned polynary coal ferrum carbon filler is in atmosphere of inert gases, by ferrum, carbon and metal catalytic element according to
After composition quality Fe:68-85%, C:10-30%, the ratio of metal catalytic element: 1%-5% mix, use
Different size of mould obtains all size polynary coal of porous alloy structure after sintering 5-8 hour at 1050 DEG C
Ferrum carbon filler.Wherein, at least during metal catalytic element can be, but not limited to platinum, palladium, rhodium, silver and ruthenium
Plant metal.This polynary coal ferrum carbon filler collection oxidation, reduction, electro-deposition, flocculate, adsorb, build bridge, roll up and sweep
And the several functions such as co-precipitation is in one.Electrification is mainly there is in the organic wastewater of difficult degradation on microelectrolysis process
Oxidation, reduction, the discharge and recharge attached collection of electricity to flco and the catalytic action to reaction learned and electrochemistry are produced
The comprehensive effect of the effects such as the net of the cohesion of thing, the absorption of nascent state flco and bed is caught, filtration.This is polynary
Coal ferrum carbon filler is very fast at the organic wastewater Anodic iron rot being passed through air, substantial amounts of Fe2+Enter in waste water,
The most effectively overcome anodic passivity, and produce nascent state Fe with greater activity2+[H], can be with useless
In water, many component generation redox reaction, destroy coloring matter chromophoric group or auxochromes unity in waste water
Structure, even chain rupture, make macromolecule toxicity organic pollution in waste water change into little molecule or be readily biodegradable
Material；Aerated reaction consumes hydrion simultaneously, makes the pH value of waste water raise, create for follow-up flocculation reaction
Good condition, saves reagent cost.
It is understood that in other embodiments, this reactor 700 can also be provided with 3,4 or count above
The reative cell of amount, can be arranged with stacking between each reative cell, it is also possible to place side by side, as long as by organic wastewater
Pass sequentially through each reative cell, and flow from the bottom up portion of each reative cell；Accordingly, along organic
The flow direction of waste water, the mean particle size of the polynary coal ferrum carbon filler in reative cell is sequentially reduced.Further,
It is understood that in other embodiments, this wastewater treatment equipment 10 can not contain pH monitoring device 400,

Device carries out purified treatment to organic wastewater.As shown in Figure 4, this method of wastewater treatment comprises the steps:
Step S910: by the pH regulator of organic wastewater to 2.5～3.
Step S920: organic wastewater is passed through in wastewater treatment equipment, and multi-stage reaction chamber is entered from inlet opening
Reactor in carry out physical filtering and microelectrolysis processing.
Step S930: discharge the organic wastewater of purified process from outlet pipe.
The most in the present embodiment, the handling process of organic wastewater is as follows:
PH is adjusted to 2.5-3 by preposition pH regulator device 100 by former organic wastewater, then passes through water inlet pipe
300 inside entering base 200, waste water is uniformly introduced by the water inlet water distribution system of water inlet pipe 300, enters gently
Enter reative cell 700, monitor waste water reaction bar continuously by the pH monitoring device 400 being arranged on base 200
Whether part meets；Open breather 500 simultaneously, ventilate slowly, simple agitation waste water, water conservancy diversion waste water
Toward upper, utilize in air oxygen by reacted ferrous oxidation；Waste water flows through gently and is loaded with polynary coal ferrum
The multi-stage reaction chamber of carbon filler, first passes through thick polynary coal ferrum carbon filler, the big float of preliminary interception, then flows
Meticulous polynary coal ferrum carbon filler, it is achieved simple filter effect, when waste water flows through polynary coal ferrum carbon system simultaneously
Constantly carry out slow reaction, larger molecular organics is degraded to small Organic substance, organic to remove most
Thing.After organic wastewater stops 1.5-2 hour in device, reach predetermined process effect, finally from the second reaction
Drain pipe 800 above room 720 flows out.After this wastewater treatment equipment 10 runs a period of time, can beat
Open exhaust-valve 610, drain and processing procedure is deposited on the impurity such as mud bottom base 200.
Backwash operation: first quit work, opens breather 500, tunes up ventilation, fills out polynary coal ferrum carbon
Material sufficiently rinses, and after static a few minutes, opens exhaust-valve 610 and empties.After emptying, close emptying
Valve 610, injects tap water from outlet pipe 800, and repeat the above steps is cleaned once.
Add or change filler: occur abnormal when this wastewater treatment equipment 10 processes water outlet or use the long period
After, polynary coal ferrum carbon filler can be adjusted or change polynary coal ferrum carbon filler.First exhaust-valve 610 is opened and put
Sky, then vertically up hangs out the second plastic filler basket 722, then vertical for the first plastic filler basket 712
Up hanging out, situation is supplemented or adjusts filler as required.Then first vertical for the first plastic filler basket 712
Put down, then the second plastic filler basket 722 is vertically put down, i.e. complete to add or change filler.
Above-mentioned wastewater treatment equipment 10 and method of wastewater treatment thereof, have the reaction of multi-stage reaction chamber by design
Device 700, the mean particle size of the polynary coal ferrum carbon filler in reactor 700 is sequentially reduced, thus organic waste
Water can be filtered layer by layer, and in reative cell with polynary coal ferrum carbon filler generation micro-electrolysis reaction, along with
The reduction of the granular size of polynary coal ferrum carbon filler, specific surface knot is gradually increased, and can process multiple difference dense
The organic wastewater of degree, particularly high concentrated organic wastewater, filters and light electrolysis through preliminary at bottom, then flows into
High level carries out depth-type filtration and light electrolysis, the advantage having the most efficiently, not hardening, and has significantly removing
While organic pollutants, improve the biodegradability of organic wastewater, established well for follow-up biological treatment
Basis.
This wastewater treatment equipment 10 collect electrochemical reaction, aoxidize, reduce, electricity flocculation, co-precipitation etc. multi-functional
In one, have that broad spectrum activity is strong, applied widely, high treating effect, not electricity consumption, low cost, operability
By force, filler replaceable, without blocking with the advantage such as harden, be through engineering approaches can be applied to difficult degradation toxicity and have at present
The agent technology of machine waste water, in decolouring, toxicity reduction, open loop chain rupture, removes COD and improves wastewater biodegradability
Etc. (B/C) aspect is widely applied.
