It determines, α chooses 0.1-0.8; The spacing of the adjacent electrode stick of the every one end of iron filler chooses 0.3m-0.5m; The length L that electrode bar is inserted into packing area is designed according to formula L=0.45H. 0-12V AC power source is set outside iron filler reaction zone, and corresponding two electrode bars of iron filler upper and lower side are connect with AC power source respectively. The present invention enhances the redox of Zero-valent Iron by extra electric field, promote macromolecular hard-degraded substance accelerated degradation, to provide advantageously condition for biological treatment, and reduce deposition of the sludge in Zero-valent Iron, improves the wastewater treatment efficiency of Zero-valent Iron Yu biological coupling system.
Description
One, technical field
The present invention relates to a kind of external electric field that adopts and strengthen the method that Zero-valent Iron-biological coupling system is handled waste water, belong to technical field of waste water processing.
Two, background technology
Because the waste water composition is complicated day by day, the usefulness of traditional biological treatment technology is restricted.At the processing of waste water difficult for biological degradation, Zero-valent Iron and life assemblage process application are more at present.Generally speaking, this process using two section reactor, be that biotic district and two zones of iron filler reaction zone separate, establish the intermediate sedimentation pond between the two, adopt mixed-liquor return to realize biological and the two coupling of iron filler, its principle mainly utilizes Zero-valent Iron to carry out redoxomorphism to endangering materials such as biological organism, heavy metal, promote the degraded of macromolecular substance, create reasonable condition for biological treatment, realize and biological synergy, and then improved biological treatment usefulness.But in actual applications, because the Zero-valent Iron chemistry there are differences water quality requirement with biological respinse, therefore guaranteeing under the biological treatment condition prerequisite, the Zero-valent Iron reaction power is low, and Zero-valent Iron is easy to be covered by organism, the surface loses activity, and electrochemical reaction is suppressed, and the synergy of the two is not given full play to.
Three, summary of the invention
The present invention is directed to the Zero-valent Iron of existing waste water difficult for biological degradation and the deficiency that the life assemblage treatment process exists, the Zero-valent Iron that provides a kind of extra electric field to strengthen--biological coupling is handled the method for waste water.
Zero-valent Iron of the present invention--biological coupling method, adopt cylindrical reactor, this cylindrical reactor comprises bio-reaction zone, settling tank and iron filler reaction zone successively, outside iron filler reaction zone the 0--12V AC power is set, corresponding two electrode bars of iron filler upper and lower ends are connected with AC power respectively.
Technical scheme of the present invention: in iron filler reaction zone the iron filler is set, the upper and lower ends of iron filler is provided with the electrode bar of number correspondence respectively,, electrode bar adopts graphite, and the overall number N of electrode bar is according to formula
Determine that wherein R is the radius of cylindrical reactor, H is the height of cylindrical reactor iron filler reaction zone, and α chooses 0.1--0.8; The spacing of the adjacent electrode rod of each end of iron filler is chosen 0.3m--0.5m; The length L that electrode bar inserts the packing area designs according to formula L=0.45H.
The present invention strengthens the speed of reaction of Zero-valent Iron in the combination process by extra electric field, strengthened the redoxomorphism of Zero-valent Iron, impel objectionable impurities, macromole hard-degraded substance accelerated degradation particularly, thereby, improved the treatment efficiency of Zero-valent Iron and biological coupling system greatly for biological treatment provides favourable condition more.
Four, accompanying drawing
Accompanying drawing 2 has provided electrode bar and AC power connection diagram; Wherein, 6 is electrode bar, 7 length L for electrode bar insertion packing area.
Accompanying drawing 3 is that the electrode bar among Fig. 2 is arranged schematic top plan view.
Five, embodiment
As shown in Figure 1, the Zero-valent Iron of present embodiment-biological coupling system adopts the cylindrical reactor of vertical layout, be followed successively by bio-reaction zone 1, settling tank 2 and iron filler reaction zone 3 from bottom to top, bio-reaction zone 1 and 3 two zones of iron filler reaction zone are separately, waste water enters reactor by bio-reaction zone 1, and the water after the processing is discharged by iron filler reaction zone 3.
In iron filler reaction zone 3, the iron filler is set, the upper and lower ends of iron filler is provided with the electrode bar 6 of number correspondence respectively, as shown in Figures 2 and 3, with graphite is electrode bar, the position of reasonable Arrangement electrode bar and spacing distance, the spacing of the adjacent electrode rod of each end of iron filler is rationally chosen 0.3m--0.5m according to wastewater property.The overall number N of electrode bar 6 is according to formula
Determine that wherein R is the radius of cylindrical reactor, H is the height of iron filler reaction zone in the cylindrical reactor, and α suitably chooses 0.1--0.8 according to the height of hard-degraded substance content in the waste water, and the high more value of hard-degraded substance content is more little.The length L that electrode bar 6 inserts the packing area designs according to formula L=0.45H.Outside iron filler reaction zone the 0--12V direct supply is set, corresponding two electrode bars 6 of iron filler upper and lower ends are connected with AC power 4 respectively.
